difference between critical thinking and critical reading

We can distinguish between critical reading and critical thinking in the following way: is a technique for information and ideas within a text. is a technique for information and ideas, for deciding what to accept and believe.Critical reading refers to a careful, active, reflective, analytic reading. Critical thinking involves reflecting on the validity of what you have read in light of our prior knowledge and understanding of the world.� As the terms are used here, is concerned with figuring out whether, within the context of the text as a whole, " " refers to the parents, the kids, or the cars, and whether the text supports that practice. would come into play when deciding whether the chosen meaning was indeed true, and whether or not you, as the reader, should support that practice. In actual practice, critical reading and critical thinking work together.� If critical thinking and critical reading are so closely linked, why is this still a useful distinction?

The usefulness of the distinction lies in its reminder that we must read each text on its own merits, not imposing our prior knowledge or views on it. While we must evaluate ideas as we read, we must not distort the meaning within a text. We must not allow ourselves to force a text to say what we would otherwise like it to say�or we will never learn anything new! We can think of a writer as having taken on a job.� No matter what the topic, certain tasks must be done:� As critical readers and writers, we want to assure ourselves that these tasks have been completed in a complete, comprehensive, and consistent manner.�Only once we have determined that a text is consistent and coherent can we then begin to evaluate whether or not to accept the assertions and conclusions.� Reading to see what a text says may suffice when the goal is to learn specific information or to understand someone else's ideas. But we usually read with other purposes. We need to solve problems, build roads, write legislation, or design an advertising campaign.� We must evaluate what we have read and integrate that understanding with our prior understanding of the world.� We must decide what to accept as true and useful.� �

Reading & Writing Purposes

Introduction: critical thinking, reading, & writing, critical thinking.

The phrase “critical thinking” is often misunderstood. “Critical” in this case does not mean finding fault with an action or idea. Instead, it refers to the ability to understand an action or idea through reasoning. According to the website SkillsYouNeed [1]:

Critical thinking might be described as the ability to engage in reflective and independent thinking.

In essence, critical thinking requires you to use your ability to reason. It is about being an active learner rather than a passive recipient of information.

Critical thinkers rigorously question ideas and assumptions rather than accepting them at face value. They will always seek to determine whether the ideas, arguments, and findings represent the entire picture and are open to finding that they do not.

Critical thinkers will identify, analyze, and solve problems systematically rather than by intuition or instinct.

Someone with critical thinking skills can:

• Understand the links between ideas.
• Determine the importance and relevance of arguments and ideas.
• Recognize, build, and appraise arguments.
• Identify inconsistencies and errors in reasoning.
• Approach problems in a consistent and systematic way.
• Reflect on the justification of their own assumptions, beliefs and values.

Critical thinking—the ability to develop your own insights and meaning—is a basic college learning goal. Critical reading and writing strategies foster critical thinking, and critical thinking underlies critical reading and writing.

Critical Reading

Critical reading builds on the basic reading skills expected for college.

College Readers’ Characteristics

• College readers are willing to spend time reflecting on the ideas presented in their reading assignments. They know the time is well-spent to enhance their understanding.
• College readers are able to raise questions while reading. They evaluate and solve problems rather than merely compile a set of facts to be memorized.
• College readers can think logically. They are fact-oriented and can review the facts dispassionately. They base their judgments on ideas and evidence.
• College readers can recognize error in thought and persuasion as well as recognize good arguments.
• College readers are skeptical. They understand that not everything in print is correct. They are diligent in seeking out the truth.

Critical Readers’ Characteristics

• Critical readers are open-minded. They seek alternative views and are open to new ideas that may not necessarily agree with their previous thoughts on a topic. They are willing to reassess their views when new or discordant evidence is introduced and evaluated.
• Critical readers are in touch with their own personal thoughts and ideas about a topic. Excited about learning, they are eager to express their thoughts and opinions.
• Critical readers are able to identify arguments and issues. They are able to ask penetrating and thought-provoking questions to evaluate ideas.
• Critical readers are creative. They see connections between topics and use knowledge from other disciplines to enhance their reading and learning experiences.
• Critical readers develop their own ideas on issues, based on careful analysis and response to others’ ideas.

The video below, although geared toward students studying for the SAT exam (Scholastic Aptitude Test used for many colleges’ admissions), offers a good, quick overview of the concept and practice of critical reading.

Critical Reading & Writing

College reading and writing assignments often ask you to react to, apply, analyze, and synthesize information. In other words, your own informed and reasoned ideas about a subject take on more importance than someone else’s ideas, since the purpose of college reading and writing is to think critically about information.

Critical thinking involves questioning. You ask and answer questions to pursue the “careful and exact evaluation and judgment” that the word “critical” invokes (definition from The American Heritage Dictionary ). The questions simply change depending on your critical purpose. Different critical purposes are detailed in the next pages of this text.

However, here’s a brief preview of the different types of questions you’ll ask and answer in relation to different critical reading and writing purposes.

When you react to a text you ask:

• “What do I think?” and
• “Why do I think this way?”

e.g., If I asked and answered these “reaction” questions about the topic assimilation of immigrants to the U.S. , I might create the following main idea statement, which I could then develop in an essay:  I think that assimilation has both positive and negative effects because, while it makes life easier within the dominant culture, it also implies that the original culture is of lesser value.

When you apply text information you ask:

• “How does this information relate to the real world?”

e.g., If I asked and answered this “application” question about the topic assimilation , I might create the following main idea statement, which I could then develop in an essay:  During the past ten years, a group of recent emigrants has assimilated into the local culture; the process of their assimilation followed certain specific stages.

When you analyze text information you ask:

• “What is the main idea?”
• “What do I want to ‘test’ in the text to see if the main idea is justified?” (supporting ideas, type of information, language), and
• “What pieces of the text relate to my ‘test?'”

e.g., If I asked and answered these “analysis” questions about the topic immigrants to the United States , I might create the following main idea statement, which I could then develop in an essay: Although Lee (2009) states that “segmented assimilation theory asserts that immigrant groups may assimilate into one of many social sectors available in American society, instead of restricting all immigrant groups to adapting into one uniform host society,” other theorists have shown this not to be the case with recent immigrants in certain geographic areas.

When you synthesize information from many texts you ask:

• “What information is similar and different in these texts?,” and
• “What pieces of information fit together to create or support a main idea?”

e.g., If I asked and answered these “synthesis” questions about the topic immigrants to the U.S. , I might create the following main idea statement, which I could then develop by using examples and information from many text articles as evidence to support my idea: Immigrants who came to the United States during the immigration waves in the early to mid 20th century traditionally learned English as the first step toward assimilation, a process that was supported by educators. Now, both immigrant groups and educators are more focused on cultural pluralism than assimilation, as can be seen in educators’ support of bilingual education. However, although bilingual education heightens the child’s reasoning and ability to learn, it may ultimately hinder the child’s sense of security within the dominant culture if that culture does not value cultural pluralism as a whole.

Critical reading involves asking and answering these types of questions in order to find out how the information “works” as opposed to just accepting and presenting the information that you read in a text. Critical writing involves recording your insights into these questions and offering your own interpretation of a concept or issue, based on the meaning you create from those insights.

Critical Reading and Reading Strategy

What is critical reading.

Reading critically does not, necessarily, mean being critical of what you read.

Both reading and thinking critically don’t mean being ‘ critical ’ about some idea, argument, or piece of writing - claiming that it is somehow faulty or flawed.

Critical reading means engaging in what you read by asking yourself questions such as, ‘ what is the author trying to say? ’ or ‘ what is the main argument being presented? ’

Critical reading involves presenting a reasoned argument that evaluates and analyses what you have read.  Being critical, therefore - in an academic sense - means advancing your understanding , not dismissing and therefore closing off learning.

See also: Listening Types to learn about the importance of critical listening skills.

To read critically is to exercise your judgement about what you are reading – that is, not taking anything you read at face value.

When reading academic material you will be faced with the author’s interpretation and opinion.  Different authors will, naturally, have different slants. You should always examine what you are reading critically and look for limitations, omissions, inconsistencies, oversights and arguments against what you are reading.

In academic circles, whilst you are a student, you will be expected to understand different viewpoints and make your own judgements based on what you have read.

Critical reading goes further than just being satisfied with what a text says, it also involves reflecting on what the text describes, and analysing what the text actually means, in the context of your studies.

As a critical reader you should reflect on:

• What the text says:  after critically reading a piece you should be able to take notes, paraphrasing - in your own words - the key points.
• What the text describes: you should be confident that you have understood the text sufficiently to be able to use your own examples and compare and contrast with other writing on the subject in hand.
• Interpretation of the text: this means that you should be able to fully analyse the text and state a meaning for the text as a whole.

Critical reading means being able to reflect on what a text says, what it describes and what it means by scrutinising the style and structure of the writing, the language used as well as the content.

Critical Thinking is an Extension of Critical Reading

Thinking critically, in the academic sense, involves being open-minded - using judgement and discipline to process what you are learning about without letting your personal bias or opinion detract from the arguments.

Critical thinking involves being rational and aware of your own feelings on the subject – being able to reorganise your thoughts, prior knowledge and understanding to accommodate new ideas or viewpoints.

Critical reading and critical thinking are therefore the very foundations of true learning and personal development.

See our page: Critical Thinking for more.

Developing a Reading Strategy

You will, in formal learning situations, be required to read and critically think about a lot of information from different sources. 

It is important therefore, that you not only learn to read critically but also efficiently.

The first step to efficient reading is to become selective.

If you cannot read all of the books on a recommended reading list, you need to find a way of selecting the best texts for you. To start with, you need to know what you are looking for.  You can then examine the contents page and/or index of a book or journal to ascertain whether a chapter or article is worth pursuing further.

Once you have selected a suitable piece the next step is to speed-read.

Speed reading is also often referred to as skim-reading or scanning.  Once you have identified a relevant piece of text, like a chapter in a book, you should scan the first few sentences of each paragraph to gain an overall impression of subject areas it covers.  Scan-reading essentially means that you know what you are looking for, you identify the chapters or sections most relevant to you and ignore the rest.

When you speed-read you are not aiming to gain a full understanding of the arguments or topics raised in the text.  It is simply a way of determining what the text is about. 

When you find a relevant or interesting section you will need to slow your reading speed dramatically, allowing you to gain a more in-depth understanding of the arguments raised.  Even when you slow your reading down it may well be necessary to read passages several times to gain a full understanding.

See also: Speed-Reading for Professionals .

Following SQ3R

SQ3R is a well-known strategy for reading. SQ3R can be applied to a whole range of reading purposes as it is flexible and takes into account the need to change reading speeds.

SQ3R is an acronym and stands for:

This relates to speed-reading, scanning and skimming the text.  At this initial stage you will be attempting to gain the general gist of the material in question.

It is important that, before you begin to read, you have a question or set of questions that will guide you - why am I reading this?  When you have a purpose to your reading you want to learn and retain certain information.  Having questions changes reading from a passive to an active pursuit.  Examples of possible questions include:

• What do I already know about this subject?
• How does this chapter relate to the assignment question?
• How can I relate what I read to my own experiences?

Now you will be ready for the main activity of reading.  This involves careful consideration of the meaning of what the author is trying to convey and involves being critical as well as active.

Regardless of how interesting an article or chapter is, unless you make a concerted effort to recall what you have just read, you will forget a lot of the important points.  Recalling from time to time allows you to focus upon the main points – which in turn aids concentration. Recalling gives you the chance to think about and assimilate what you have just read, keeping you active.  A significant element in being active is to write down, in your own words, the key points. 

The final step is to review the material that you have recalled in your notes.  Did you understand the main principles of the argument?  Did you identify all the main points?  Are there any gaps?   Do not take for granted that you have recalled everything you need correctly – review the text again to make sure and clarify.

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment.

For details on this history, see the Supplement on History .

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o’clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68–69; 1933: 91–92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot’s position, it must appear to project far out in front of the boat. Moreover, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69–70; 1933: 92–93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond lane from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses. As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009, 2021), others on the resulting judgment (Facione 1990a), and still others on responsiveness to reasons (Siegel 1988). Kuhn (2019) takes critical thinking to be more a dialogic practice of advancing and responding to arguments than an individual ability.

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in spacing in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the spacing of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016a) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Facione (1990a: 25) divides “affective dispositions” of critical thinking into approaches to life and living in general and approaches to specific issues, questions or problems. Adapting this distinction, one can usefully divide critical thinking dispositions into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking. In three studies, Haran, Ritov, & Mellers (2013) found that actively open-minded thinking, including “the tendency to weigh new evidence against a favored belief, to spend sufficient time on a problem before giving up, and to consider carefully the opinions of others in forming one’s own”, led study participants to acquire information and thus to make accurate estimations.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), Black (2012), and Blair (2021).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work. It is also helpful to be aware of the prevalence of “noise” (unwanted unsystematic variability of judgments), of how to detect noise (through a noise audit), and of how to reduce noise: make accuracy the goal, think statistically, break a process of arriving at a judgment into independent tasks, resist premature intuitions, in a group get independent judgments first, favour comparative judgments and scales (Kahneman, Sibony, & Sunstein 2021). It is helpful as well to be aware of the concept of “bounded rationality” in decision-making and of the related distinction between “satisficing” and optimizing (Simon 1956; Gigerenzer 2001).

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? In a comprehensive meta-analysis of experimental and quasi-experimental studies of strategies for teaching students to think critically, Abrami et al. (2015) found that dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), Bailin et al. (1999b), and Willingham (2019).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.

The purposes and practices of reading

The way we read depends on what we’re reading and why we’re reading it. The way we read a novel is different to the way we read a menu . Perhaps we are reading to understand a subject, to increase our knowledge, to analyse data, to retrieve information, or maybe even to have fun! The purpose of our reading will determine the approach we take.

Reading for information

Suppose we were trying to find some directions or opening hours... We would need to scan the text for key words or phrases that answer our question, and then we would move on.

It's a bit like doing a Google search and then just reading the results page rather than accessing the website.

Reading for understanding

When we're reading for pleasure or doing background reading on a topic, we'll generally read the text once, from start to finish . We might apply skimming techniques to look through the text quickly and get the general gist. Our engagement with the text might therefore be quite passive: we're looking for a general understanding of what's being written, perhaps only taking in the bits that seem important.

Reading for analysis

When we're doing reading for an essay, dissertation, or thesis, we're going to need to actively read the text multiple times . All the while we'll engage our prior knowledge and actively apply it to our reading, asking questions of what's been written.

This is critical reading !

Reading strategies

When you’re reading you don’t have to read everything with the same amount of care and attention. Sometimes you need to be able to read a text very quickly.

There are three different techniques for reading:

• Scanning — looking over material quite quickly in order to pick out specific information;
• Skimming — reading something fairly quickly to get the general idea;
• Close reading — reading something in detail.

You'll need to use a combination of these methods when you are reading an academic text: generally, you would scan to determine the scope and relevance of the piece, skim to pick out the key facts and the parts to explore further, then read more closely to understand in more detail and think critically about what is being written.

These strategies are part of your filtering strategy before deciding what to read in more depth. They will save you time in the long run as they will help you focus your time on the most relevant texts!

You might scan when you are...

• ...browsing a database for texts on a specific topic;
• ...looking for a specific word or phrase in a text;
• ...determining the relevance of an article;
• ...looking back over material to check something;
• ...first looking at an article to get an idea of its shape.

Scan-reading essentially means that you know what you are looking for. You identify the chapters or sections most relevant to you and ignore the rest. You're scanning for pieces of information that will give you a general impression of it rather than trying to understand its detailed arguments.

You're mostly on the look-out for any relevant words or phrases that will help you answer whatever task you're working on. For instance, can you spot the word "orange" in the following paragraph?

Being able to spot a word by sight is a useful skill, but it's not always straightforward. Fortunately there are things to help you. A book might have an index, which might at least get you to the right page. An electronic text will let you search for a specific word or phrase. But context will also help. It might be that the word you're looking for is surrounded by similar words, or a range of words associated with that one. I might be looking for something about colour, and see reference to pigment, light, or spectra, or specific colours being called out, like red or green. I might be looking for something about fruit and come across a sentence talking about apples, grapes and plums. Try to keep this broader context in mind as you scan the page. That way, you're never really just going to be looking for a single word or orange on its own. There will normally be other clues to follow to help guide your eye.

Approaches to scanning articles:

• Make a note of any questions you might want to answer – this will help you focus;
• Pick out any relevant information from the title and abstract – Does it look like it relates to what you're wanting? If so, carry on...
• Flick or scroll through the article to get an understanding of its structure (the headings in the article will help you with this) – Where are certain topics covered?
• Scan the text for any facts , illustrations , figures , or discussion points that may be relevant – Which parts do you need to read more carefully? Which can be read quickly?
• Look out for specific key words . You can search an electronic text for key words and phrases using Ctrl+F / Cmd+F. If your text is a book, there might even be an index to consult. In either case, clumps of results could indicate an area where that topic is being discussed at length.

Once you've scanned a text you might feel able to reject it as irrelevant, or you may need to skim-read it to get more information.

You might skim when you are...

• ...jumping to specific parts such as the introduction or conclusion;
• ...going over the whole text fairly quickly without reading every word;

Skim-reading, or speed-reading, is about reading superficially to get a gist rather than a deep understanding. You're looking to get a feel for the content and the way the topic is being discussed.

Skim-reading is easier to do if the text is in a language that's very familiar to you, because you will have more of an awareness of the conventions being employed and the parts of speech and writing that you can gloss over. Not only will there be whole sections of a text that you can pretty-much ignore, but also whole sections of paragraphs. For instance, the important sentence in this paragraph is the one right here where I announce that the important part of the paragraph might just be one sentence somewhere in the middle. The rest of the paragraph could just be a framework to hang around this point in order to stop the article from just being a list.

However, it may more often be that the important point for your purposes comes at the start of the paragraph. Very often a paragraph will declare what it's going to be about early on, and will then start to go into more detail. Maybe you'll want to do some closer reading of that detail, or maybe you won't. If the first paragraph makes it clear that this paragraph isn't going to be of much use to you, then you can probably just stop reading it. Or maybe the paragraph meanders and heads down a different route at some point in the middle. But if that's the case then it will probably end up summarising that second point towards the end of the paragraph. You might therefore want to skim-read the last sentence of a paragraph too, just in case it offers up any pithy conclusions, or indicates anything else that might've been covered in the paragraph!

For example, this paragraph is just about the 1980s TV gameshow "Treasure Hunt", which is something completely irrelevant to the topic of how to read an article. "Treasure Hunt" saw two members of the public (aided by TV newsreader Kenneth Kendall) using a library of books and tourist brochures to solve a series of five clues (provided, for the most part, by TV weather presenter Wincey Willis). These clues would generally be hidden at various tourist attractions within a specific county of the British Isles. The contestants would be in radio contact with a 'skyrunner' (Anneka Rice) who had a map and the use of a helicopter (piloted by Keith Thompson). Solving a clue would give the contestants the information they needed to direct the skyrunner (and her crew of camera operator Graham Berry and video engineer Frank Meyburgh) to the location of the next clue, and, ultimately, to the 'treasure' (a token object such as a little silver brooch). All of this was done against the clock, the contestants having only 45' to solve the clues and find the treasure. This, necessarily, required the contestants to be able to find relevant information quickly: they would have to select the right book from the shelves, and then navigate that text to find the information they needed. This, inevitably, involved a considerable amount of skim-reading. So maybe this paragraph was slightly relevant after all? No, probably not...

Skim-reading, then, is all about picking out the bits of a text that look like they need to be read, and ignoring other bits. It's about understanding the structure of a sentence or paragraph, and knowing where the important words like the verbs and nouns might be. You'll need to take in and consider the meaning of the text without reading every single word...

Approaches to skim-reading articles:

• Pick out the most relevant information from the title and abstract – What type of article is it? What are the concepts? What are the findings?;
• Scan through the article and note the headings to get an understanding of structure;
• Look more closely at the illustrations or figures ;
• Read the conclusion ;
• Read the first and last sentences in a paragraph to see whether the rest is worth reading.

After skimming, you may still decide to reject the text, or you may identify sections to read in more detail.

Close reading

You might read closely when you are...

• ...doing background reading;
• ...trying to get into a new or difficult topic;
• ...examining the discussions or data presented;
• ...following the details or the argument.

Again, close reading isn't necessarily about reading every single word of the text, but it is about reading deeply within specific sections of it to find the meaning of what the author is trying to convey. There will be parts that you will need to read more than once, as you'll need to consider the text in great detail in order to properly take in and assess what has been written.

Approaches to the close reading of articles:

• Focus on particular passages or a section of the text as a whole and read all of its content – your aim is to identify all the features of the text;
• Make notes and annotate the text as you read – note significant information and questions raised by the text;
• Re-read sections to improve understanding;
• Look up any concepts or terms that you don’t understand.

Questioning

Questioning goes hand-in-hand with reading for analysis. Before you begin to read, you should have a question or set of questions that will guide you. This will give purpose to your reading, and focus you; it will change your reading from a passive pursuit to an active one, and make it easier for you to retain the information you find. Think about what you want to achieve and keep the purpose in mind as you're reading.

Ask yourself...

• Why am I reading this? — What is my task or assignment question, and how is this source helping to answer it?
• What do I already know about the subject? — How can I relate what I'm reading to my own experiences?

You'll need to ask questions of the text too:

• Examine the evidence or arguments presented;
• Check out any influences on the evidence or arguments;
• Check the limitations of study design or focus;
• Examine the interpretations made.

Are you prepared to accept the authors’ arguments, opinions, or conclusions?

Critical reading: why, what, and how

Blocks to critical reading.

Certain habits or approaches we have to life can hold us back from really thinking objectively about issues. We may not realise it, but often we're our own worst enemies when it comes to being critical...

Select a student to reveal the statement they've made.

I have been asked to work on an area that is completely new. Where do I start in terms of finding relevant texts?

Ask for guidance:

ask your tutor or module leader

use your module reading lists

make use of the Skills Guides (oh... you are! Excellent!)

ask your Faculty Librarians

Take a look at our contextagon and begin to consider sources of information .

I don’t understand what I'm reading – It's too difficult!

If the text is difficult, don’t panic!

If it is a journal article, scan the text first – look at the contents, abstract, introduction, conclusion and subheadings to try to make sense of the argument.

Then read through the whole text to try to understand the key messages, rather than every single word or section. On a second reading, you will find it easier to understand more.

If you are struggling to get to grips with theories or concepts, you might find it useful to look at a summary as a way in -- for example, in an online subject encyclopaedia .

If you are struggling with difficult vocabulary, it may be useful to keep a glossary of key vocabulary, particularly if it is specialist or technical.

Remember, the more you read, the more you will understand it and be able to use it yourself.

Take a look at our Academic sources Skills Guide .

Help! There is too much to read and too little time!

University study involves a large amount of reading. However, some texts on your reading lists are core texts and some are more optional.

You will generally need to read the core text, but on the optional list there may be a range of texts which deal with the same topic from different perspectives. You will need to decide which are the most relevant to your interests and assignments.

Keep in mind the questions you want the text to answer and look for what is relevant to those questions. Prioritise and read only as much as you need to get the information you need (if it's a book, use the index; if it's an article, concentrate on the relevant parts).

Improve your note-taking skills by keeping them brief and selective.

If in doubt, ask your tutor or Faculty Librarians for guidance.

Take a look at the Organise and Analyse section of the Skills Guides.

I am struggling to remember what I have read.

To remember what you have read, you need to interact with the material. If you have questioned and evaluated the material you are reading, you will find it easier to remember.

Improve your active note-taking skills using a method like Cornell or Survey, Question, Read, Recite, Review (SQR3).

Annotate your pdfs and use a note-taking app .

Make time to consolidate your reading periodically. You could do this by summarising key points from memory or connecting ideas using mindmapping.

Consider using a reference management program to keep on top of reading, and mind-mapping software like Mindgenius to connect ideas.

Where did I read that thing?

Make sure you have a good system for taking notes and try to keep your notes organised/in one place, whether that is using an app or taking notes by hand. There is no right way to do this - find a system that works for you.

Logically label and file your notes, linking new information with what you already know and cross-reference with any handouts.

Make sure you make a note of information for referencing sources.

Where possible, save resources you have used to Google Drive or your University filestore , and organise these (e.g. by module, assessment, topic etc.).

Many of the above tips can be achieved with reference management software .

I have strong opinions about the argument being presented in the reading – why can’t I just put this side forward?

Truth is a complicated business. Core texts or texts by highly respected authors are an author’s interpretation, and that interpretation is not above question. Any single text only provides a perspective. Even a scientific observation may be modified by further evidence. Critical writing means making sure your argument is balanced, considering and critiquing a range of perspectives.

Read texts objectively and assess their value in terms of what they can bring to your work, rather than whether you agree with them or not.

If you agree or disagree strongly with an author, you still need to analyse their argument and justify why it is sound or unsound, reliable or unreliable, and valid or lacking validity.

Ignoring opposing views can be a mistake. Your reader may think you are unaware of the different views or are not willing to think the ideas through and challenge them.

Be careful not to be blinded by your own views about a topic or an author. Engaging actively with a text which you initially don’t agree with can mean you have to rethink or adjust your own position, making your final argument stronger.

Take a look at the other parts of the Being critical Skills Guides .

That's not right. Try again.

Being actively critical

Active reading is about making a conscious effort to understand and evaluate a text for its relevance to your studies. You would actively try to think about what the text is trying to say, for example by making notes or summaries.

Critical reading is about engaging with the text by asking questions rather than passively accepting what it says. Is the methodology sound? What was the purpose? Do ideas flow logically? Are arguments properly formulated? Is the evidence there to support what is being claimed?

When you're reading critically, you're looking to...

• ...link evidence to your own research;
• ...compare and contrast different sources effectively;
• ...focus research and sources;
• ...synthesise the information you've found;
• ...justify your own arguments with reference to other sources.

You're going beyond just an understanding of a text. You're asking questions of it; making judgements about it... What you're reading is no longer undisputed 'fact': it's an argument put forward by an author. And you need to determine whether that argument is a valid one.

"Reading without reflecting is like eating without digesting"

– Edmund Burke

"Feel free to reflect on the merits (or not) of that quote..."

– anon.

Critical reading involves understanding the content of the text as well as how the subject matter is developed...

• How true is what's being written?
• How significant are the statements that are being made?

Regardless of how objective, technical, or scientific the text may be, the authors will have made certain decisions during the writing process, and it is these decisions that we will need to examine.

Two models of critical reading

There are several approaches to critical reading. Here's a couple of models you might want to try:

Choose a chapter or article relevant to your assessment (or pick something from your reading list).

Then do the following:

Determine broadly what the text is about.

Look at the front and back covers

Scan the table of contents

Look at the title, headings, and subheadings

Read the abstract, introduction and conclusion

Are there any images, charts, data or graphs?

What are the questions the text will answer? Write some down.

Use the title, headings and subheadings to write questions

What questions do the abstract, introduction and conclusion prompt?

What do you already know about the topic? What do you need to know?

Do a first reading. Read selectively.

Read a section at a time

Answer your questions

Summarise or make brief notes

Underline or highlight any key points

Recite (in your own words)

Recall the key points.

Summarise key points from memory

Try to answer the questions you asked orally, without looking at the text or your notes

Use diagrams or mindmaps to recall the information

After you have completed the reading…

Go back over your notes and check they are clear

Check that you have answered all your questions

At a later date, review your notes to check that they make sense

At a later date, review the questions and see how much you can recall from memory

Choose a relevant article from your reading list and make brief notes on it using the prompts below.

Choose an article you have read earlier in your course and re-read it, applying the prompts below.

Compare your comments and the notes you have made. What are the differences?

Who is the text by? Who is the text aimed at? Who is described in the text?

What is the text about? What is the main point, problem or topic? What is the text's purpose?

Where is the problem/topic/issue situated?, and in what context?

When does the problem/topic/issue occur, and what is its context? When was the text written?

How did the topic/problem/issue occur? How does something work? How does one factor affect another? How does this fit into the bigger picture?

Why did the topic/problem/issue occur? Why was this argument/theory/solution used? Why not something else?

What if this or that factor were added/removed/altered? What if there are alternatives?

So what makes it significant? So what are the implications? So what makes it successful?

What next in terms of how and where else it's applied? What next in terms of what can be learnt? What next in terms of what needs doing now?

Here's a template for use with the model.

Arguments & evidence

Academic reading can be a trial. In more ways than one...

It might help to think of every text you read as a witness in a court case. And you're the judge ! You're going to need to examine the testimony...

• What’s being claimed ?
• What are the reasons for making that claim?
• Are there gaps in the evidence?
• Do other witnesses support and corroborate their testimony?
• Does the testimony support the overall case ?
• How does the testimony relate to the other witnesses?

You're going to need to consider all sides of the case...

Considering the argument

An argument explains a position on something. A lot of academic writing is about gathering those claims and explaining your own position through their explanations.

You'll need to question...

• ...the author's claims ;
• ...the arguments they use — are their claims well documented ?;
• ...the counter-arguments presented;
• ...any bias in the source;
• ...the research method being used;
• ...how the author qualifies their arguments.

You'll also need to develop your own reasoned arguments, based on a logical interpretation of reliable sources of information.

What's the evidence?

Evidence isn't just the results of research or a reference to an academic study. You might use other authors' opinions to back up your argument. Keep in mind that some evidence is stronger than others:

You can get an idea of an author's certainty through the language they use, too:

Linking evidence to argument

• Why did the author select the evidence they did? — Why did they decide to use a particular methodology, choose a specific method, or conduct the work in the way they did?
• How does the author interpret the evidence?
• How does the evidence prove or help the argument?

Even in the most technical and scientific disciplines, the presentation of argument will always involve elements that can be examined and questioned. For example, you could ask:

• Why did the author select that particular topic of enquiry in the first place?
• Why did the author select that particular process of analysis?

Synthesis :

"the combination of components or elements to form a connected whole."

You'll need to make logical connections between the different sources you encounter, pulling together their findings. Are there any patterns that emerge?

Analyse the texts you've found, and how meaningful they are in context of your studies...

• How do they compare to each other and to any other knowledge you are gathering about the subject? Do some ideas complement or conflict with each other?
• How will you synthesise the different sources to serve an idea you are constructing? Are there any inferences you can draw from the material?

Embracing other perspectives

Good critical research seeks to be impartial, and will embrace (or, at the very least, address) conflicting opinions. Try to bring these into your research to show comprehensive searching and knowledge of the subject.

You can strengthen your argument by explaining, critically, why one source is more persuasive than another.

Recall & review

Synthesising research is much easier if you take notes. When you know an article is relevant to your area of research, read it and make notes which are relevant to you. Consider keeping a spreadsheet or something similar , to make a note of what you have read and how it relates to the task.

You don't need elaborate notes; just a summary of the relevant details. But you can use your notes to help with the process of analysing and synthesising the texts. One method you could try is the recall & review approach:

Try to summarise key words and elements of the text:

• Sketch a rough diagram of the text from memory — test what you can recall from your reading of the text;
• Make headings of the main ideas and note the supporting evidence;
• Include your evaluation — what were the strengths and weaknesses?
• Identify any gaps in your memory.

Go over your notes, focusing on the parts you found difficult. Organise your notes, re-read parts, and start to bring everything together...

• Summarise the text in preparation for writing;
• Be creative: use colour and arrows; make it easy to visualise;
• Highlight the ideas you may want to make use of;
• Identify areas for further research.

Critical analysis vs criticism

The aim of critical reading and critical writing is not to find fault; it's not about focusing on the negative or being derogatory. Rather it's about assessing the strength of the evidence and the argument. It's just as useful to conclude that a study or an article presents very strong evidence and a well-reasoned argument as it is to identify weak evidence and poorly formed arguments.

Criticising

The author's argument is poor because it is badly written.

Critical analysis

The author's argument is unconvincing without further supporting evidence.

Critical reading Making judgements about a text

In academic contexts you cannot assume that everything you read is a simple representation of the facts. Every area of study has many different perspectives, and you will need to understand not only what a writer is saying, but how and why they are saying it, in order to judge how credible the information and arguments are. This involves reading critically. This section explains in detail what critical reading is , compares critical reading to active reading , and explains how to read critically by considering the author and source , the evidence the writer uses, and the assumptions and bias the writer may have. There is also a checklist to help you check your understanding of this section.

What is critical reading?

The most common form of the word critical is 'to criticise or find fault with something'. This is different, however, from the meaning of the word when used in phrases such as critical thinking , critical writing or critical reading . In this context the word means 'exercising careful judgement and evaluating the evidence'. Critical reading, therefore, involves questioning a text, rather than assuming everything it contains is factual. This means that in addition to what a text says, the reader needs to consider how it says it, who is saying it, when it was said, where it was said (i.e. published), and why it was said (i.e. the writer's purpose), in order to be able to evaluate the evidence and make a careful judgement as to how trustworthy the information is. This may be important in deciding whether and how to use this source, for example in your own writing.

Critical reading vs. active reading

Many authors equate critical reading and active reading, though in fact they are not the same. Active reading involves engaging with a text in order to understand what it contains. This could mean highlighting key words and phrases, making annotations in the margin, testing yourself as you read, discussing with or explaining it to someone else after reading, as well as reading critically by asking questions about the text. Critical reading is therefore a form of active reading, but is only one of several ways to read actively. This means that it is possible to read a text actively, for example by highlighting it and making annotations, without reading critically.

How to read critically

In order to read critically you will need to ask certain questions about the text. One area to consider is the author and source . Questions for this area can be asked before you read the text, and are mostly quite straightforward. Answers to these questions may help you decide whether the text is worth reading at all. Another area to consider is the evidence the writer uses to support his points. These questions are more difficult, and require careful reading of the text and consideration of the meaning. Being able to answer questions such as these will also improve your ability as a writer. A final area to look at is the assumptions and bias which the writer may have. These are the most difficult questions, and may need you to analyse the language the writer uses in order to answer them.

Questions on each of these areas are given below. There are 20 questions in total. These questions can be asked in any order, and you do not need to find answers to all of them. Some are wh- questions, while others are yes/no questions. The yes/no questions have been phrased so that the answer should be 'Yes' if this it is a reliable source, while the answer 'No' would indicate some potential problems. If there are too many 'No' answers it would indicate that this is perhaps not a source you should be using in your academic writing.

Author/source

The following questions relate to the author and source.

• Who is the author? Is the author an expert in this field?
• What is the source of the text? Is it trustworthy?
• When was it published? Is it recent?
• Who is the intended audience?
• What is the author's purpose? Is it a neutral purpose (e.g. to explain or to inform ) rather than a more biased purpose (e.g. to persuade )?

The following questions relate to the evidence the writer uses.

• How strong is the evidence?
• Are all the points made by the author supported by evidence?
• Does the writer avoid making unsupported generalisations?
• Is there a clear distinction between fact and the author’s opinion?
• Are citations used? If so, are the cited sources trustworthy and recent?
• If there are any images or diagrams, are they clear? Do they relate directly to points in the text and support the author’s argument?
• If it is a research article, is the methodology valid (e.g. sample size, method of sampling)? Are the limitations clear? Are the results consistent with the objectives?

Assumptions/bias

The following questions relate to the assumptions the writer has, and any potential bias.

• What assumptions has the writer made? Are they clear to the reader? Are they valid?
• What is the author’s stance (i.e. position) on the topic? Is this explicit?
• Does the writer present a balanced viewpoint? Are other viewpoints considered (e.g. via counter-arguments )?
• Does the writer represent the ideas of others accurately?
• Are the writer's conclusions reasonable in the light of the evidence presented?
• Is the writer's language neutral? Does the writer use tentative language (e.g. It appears that... This may be caused by... ) and avoid the use of emphatic words/phrases (e.g. It is obvious... Clearly... Of course... )?
• Does the writer avoid using emotional language and dramatic images?
• Are the examples representative and free from bias?

Scanning a text means looking through it quickly to find specific information, and is one way to read a text quickly.

Guessing meaning of unknown words entails using context, prefixes, suffixes and roots and can speed up reading.

Summarising is one of three ways of using another writer's work in your own (along with quotation and paraphrase).

Critical reading involves questioning a text, rather than assuming everything it contains is factual.

Surveying a text involves taking a broad look at a text to decide whether it is worth reading more closely.

Establishing a purpose before reading a text determines how you read it, which may not be from start to finish.

Critical thinking for critical writing

On this page, non-critical vs. critical reading, modes of critical analysis, steps to writing critically, implications for writing.

Critical writing depends on critical thinking. Your writing will involve reflection on written texts: that is, critical reading.

Your critical reading of a text and thinking about a text enables you to use it to make your own arguments. As a critical thinker and writer, you make judgments and interpretations of the ideas, arguments, and claims of others presented in the texts you read.

The key is this: don’t read looking only or primarily for information . Instead, read to determine ways of thinking about the subject matter.

Non-critical   reading is focused on learning the information provided by a source. In this mode, a reader focuses on understanding the information, ideas, and opinions stated within the text. 

Sometimes non-critical reading is a part of our day-to-day lives. For example, we may consult a weather report to help us decide whether or not we need to pack an umbrella when we leave the house. Often, we don't need to be critical readers to get the information we need about the weather. However, if the weather report states that it will be a "sunny, cloudless day" and we can see that it is pouring outside our window, we will likely bring our critical reading abilities back into play! 

How to read critically

1. Determine the central claims or purpose of the text (its thesis). A critical reading attempts to identify and assess how these central claims are developed and argued.

2. Begin to make some judgments about context .

• What audience is the text written for?
• Who is it in dialogue with?
• In what historical context is it written?

3. Distinguish the kinds of reasoning the text employs.

• What concepts are defined and used?
• Does the text appeal to a theory or theories?
• Is any specific methodology laid out?
• If there is an appeal to a particular concept, theory, or method, how is that concept, theory, or method then used to organize and interpret the data?
• How has the author analyzed (broken down) the material?

4. Examine the evidence (the supporting facts, examples, etc.) the text employs. Supporting evidence is indispensable to an argument, so consider the kinds of evidence used: Statistical? Literary? Historical? From what sources is the evidence taken? Are these sources primary or secondary?

5. Critical reading may involve evaluation . Your reading of a text is already critical if it accounts for and makes a series of judgments about how a text is argued. Some assignments may also require you to assess the strengths and weaknesses of an argument.

Why to read critically

Critical reading is an important step for many academic assignments. Critically engaging with the work of others is often a first step in developing our own arguments, interpretations, and analysis. 

Critical reading often involves re-reading a text multiple times, putting our focus on different aspects of the text. The first time we read a text, we may be focused on getting an overall sense of the information the author is presenting - in other words, simply understanding what they are trying to say. On subsequent readings, however, we can focus on how the author presents that information, the kinds of evidence they provide to support their arguments (and how convincing we find that evidence), the connection between their evidence and their conclusions, etc. etc. 

Example:  A non-critical thinker/reader might read a history book to learn the facts of the situation or to discover an accepted interpretation of those events.

A critical thinker/reader might read the same work to appreciate how a particular perspective on the events and a particular selection of facts can lead to a particular understanding. A critical thinker/reader will likely also think about the perspectives of that event that are NOT being considered or presented in the text. 

What a text says  – restatement . Talks about the same topic as the original text. What a text does – description . Focuses on aspects of the discussion itself. What a text means – interpretation . Analyzes the text and asserts a meaning for the text as a whole.

TIP: An interpretation includes references to the content (the specific actions referred to), the language (the specific terms used), and the structure (such as the relationship between characters).

1. Take a critical stance:  recognize that every text, author, and argument comes from a perspective and is subject to interpretation and analysis.

2. Pay close attention : read texts not just for  what they say  but also for  how they say it . Notice examples, evidence, word choice, structure, etc. Consider the "fit" between the information a text provides and the way it provides that information. 

3. Think big picture : read texts in their context. This can sometimes also involve doing some research about your sources to learn more about the author, the time in which the text was written, the sources that funded the research, etc. 

4. Bring yourself in : critical writing also involves developing your own understandings, interpretations, analysis, and arguments in response to the texts you are reading. Sometimes this is accomplished by considering the connections/points of divergence between several texts you are reading. It can also involve bringing in your own perspectives and experiences to support or challenge evidence, examples, and/or conclusions. 

Writing critically involves:

• Providing appropriate and sufficient arguments and examples
• Choosing terms that are precise, appropriate, and persuasive
• Making clear the transitions from one thought to another to ensure the overall logic of the presentation
• Editing for content, structure, and language

An increased awareness of the impact of choices of content, language, and structure can help you as a writer to develop habits of rewriting and revision.

What Is Critical Thinking? | Definition & Examples

Published on May 30, 2022 by Eoghan Ryan . Revised on May 31, 2023.

Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its research findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarize it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it peer-reviewed ?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

The definition of critical reading means reading with the goal of finding a deep understanding of the material, whether it is fiction or nonfiction . It is the act of analyzing and evaluating what you are reading as you make your way through the text or as you reflect back upon your reading.

Using Your Head

When you read a piece of fiction critically, you use your common sense to determine what the writer means, as opposed to what the written words actually say. The following passage appears in " The Red Badge of Courage ", the classic Civil War-era work by Stephen Crane. In this passage, the main character, Henry Fleming, has just returned from battle and is now receiving treatment for a nasty head wound.

"Yeh don't holler ner say nothin'... an' yeh never squeaked. Yer a good un, Henry. Most 'a men would a' been in th' hospital long ago. A shot in th' head ain't foolin' business..."

The point seems clear enough. Henry is receiving praise for his apparent fortitude and bravery. But what is really happening in this scene?

During the confusion and terror of the battle, Henry Fleming had actually panicked and run away, abandoning his fellow soldiers in the process. He had received the blow in the chaos of retreat; not the frenzy of battle. In this scene, he was feeling ashamed of himself.

When you read this passage critically, you actually read between the lines. By doing so, you determine the message that the author is really conveying. The words speak of bravery, but the real message of this scene is concerned feelings of cowardice that tormented Henry.

Shortly after the scene above, Fleming realizes that nobody in the entire regiment knows the truth about his wound. They all believe that the wound was the result of fighting in the battle:

His self-pride was now entirely restored....He had performed his mistakes in the dark, so he was still a man.

Despite the claim that Henry feels relieved, we know by reflecting and thinking critically that Henry isn't really comforted. By reading between the lines, we know he is deeply bothered by the sham.

What's the Lesson?

One way to read a novel critically is to be aware of the lessons or messages that a writer is sending in a subtle way.

After reading "The Red Badge of Courage", a critical reader would reflect back on the many scenes and look for a lesson or a message. What is the writer trying to say about courage and war?

The good news is, there isn't a right or wrong answer. It's the act of forming a question and offering your own opinion that counts.

Nonfiction writing can be just as tricky to evaluate as fiction, although there are differences. Nonfiction writing normally involves a series of statements that are backed by evidence.

As a critical reader, you will need to be mindful of this process. The goal of critical thinking is to evaluate information in an unbiased way. This includes being open to changing your mind about a subject if the good evidence exists. However, you should also try not to be influenced by unsound evidence.

The trick to critical reading in nonfiction is to know how to separate the good evidence from the bad.

There are signs to look out for when it comes to misleading or bad evidence.

Assumptions

Watch for broad, unsupported statements like "most people in the pre-war South approved of enslavement ." Every time you see a statement, ask yourself if the author provides any evidence to back up his point.

Implications

Be mindful of subtle statements such as "Statistics support those who argue that boys are better at math than girls, so why should this be such a controversial issue?"

Don't become distracted by the fact that some people do believe that males are naturally better at math, and address that issue. When you do this, you are accepting the implication and, therefore, falling for bad evidence.

The point is, in critical reading, that the author has not provided statistics ; he merely implied that statistics exist.

Critical reading: what is critical reading, and why do i need to do it.

Critical reading means that a reader applies certain processes, models, questions, and theories that result in enhanced clarity and comprehension. There is more involved, both in effort and understanding, in a critical reading than in a mere "skimming" of the text. What is the difference? If a reader "skims" the text, superficial characteristics and information are as far as the reader goes. A critical reading gets at "deep structure" (if there is such a thing apart from the superficial text!), that is, logical consistency, tone, organization, and a number of other very important sounding terms.

What does it take to be a critical reader? There are a variety of answers available to this question; here are some suggested steps:

1. Prepare to become part of the writer's audience.

After all, authors design texts for specific audiences, and becoming a member of the target audience makes it easier to get at the author's purpose. Learn about the author, the history of the author and the text, the author's anticipated audience; read introductions and notes.

2. Prepare to read with an open mind.

Critical readers seek knowledge; they do not "rewrite" a work to suit their own personalities. Your task as an enlightened critical reader is to read what is on the page, giving the writer a fair chance to develop ideas and allowing yourself to reflect thoughtfully, objectively, on the text.

3. Consider the title.

This may seem obvious, but the title may provide clues to the writer's attitude, goals, personal viewpoint, or approach.

4. Read slowly.

Again, this appears obvious, but it is a factor in a "close reading." By slowing down, you will make more connections within the text.

5. Use the dictionary and other appropriate reference works.

If there is a word in the text that is not clear or difficult to define in context: look it up. Every word is important, and if part of the text is thick with technical terms, it is doubly important to know how the author is using them.

6. Make notes.

Jot down marginal notes, underline and highlight, write down ideas in a notebook, do whatever works for your own personal taste. Note for yourself the main ideas, the thesis, the author's main points to support the theory. Writing while reading aids your memory in many ways, especially by making a link that is unclear in the text concrete in your own writing.

7. Keep a reading journal

In addition to note-taking, it is often helpful to regularly record your responses and thoughts in a more permanent place that is yours to consult. By developing a habit of reading and writing in conjunction, both skills will improve.

Critical reading involves using logical and rhetorical skills. Identifying the author's thesis is a good place to start, but to grasp how the author intends to support it is a difficult task. More often than not an author will make a claim (most commonly in the form of the thesis) and support it in the body of the text. The support for the author's claim is in the evidence provided to suggest that the author's intended argument is sound, or reasonably acceptable. What ties these two together is a series of logical links that convinces the reader of the coherence of the author's argument: this is the warrant. If the author's premise is not supportable, a critical reading will uncover the lapses in the text that show it to be unsound.

4 – Critical Writing

Critical writing depends on critical thinking. Your writing will involve reflection on written texts: that is, critical reading.

[Source: Lane, 2021, Critical Thinking for Critical Writing ]

Critical writing entails the skills of critical thinking and reading. At college, the three skills are interdependent, reflected in the kinds of assignments you have to do.

Now let’s look at some real university-level assignments across different majors. Pay attention to the highlighted words used in the assignment descriptions.

As you can tell, all the assignments have both critical reading and writing components. You have to read a lot (e.g., “Use at least 5 current Economics research articles,” “refer to 2 other documents,” and “Select 4-5 secondary sources”) and critically before you form your own opinions and then start to write. Sometimes reading is for ideas and evidence (i.e., reasons, examples, and information from sources), and other times reading is to provide an evaluation of information accuracy (e.g., research designs, statistics). Without critical thinking and reading, critical writing will have no ground. Critical thinking and reading are the prerequisites for critical writing. A clear definition of critical writing is provided below.

What is Critical Writing?

Critical writing is writing which analyses and evaluates information, usually from multiple sources, in order to develop an argument. A mistake many beginning writers make is to assume that everything they read is true and that they should agree with it, since it has been published in an academic text or journal. Being part of the academic community, however, means that you should be critical of (i.e. question) what you read, looking for reasons why it should be accepted or rejected, for example by comparing it with what other writers say about the topic, or evaluating the research methods to see if they are adequate or whether they could be improved.

[Source: Critical Writing ]

If you are used to accepting the ideas and opinions stated in a text, you have to relearn how to be critical in evaluating the reliability of the sources, particularly in the online space as a large amount of online information is not screened. In addition, critical writing is different from the types of writing (e.g., descriptive writing) you might have practiced in primary and secondary education.

The following table gives some examples to show the difference between descriptive and critical writing (adapted from the website ). Pay attention to the different verbs used in the Table for the comparisons.

You might feel familiar with the verbs used in the column describing critical writing. If you still remember, those words are also used to depict the characteristics of critical thinking and reading.

ACTIVITY #1:

Read the two writing samples, identify which one is descriptive writing and which one is critical writing, and explain your judgment.

Sample 1: Recently, President Jacob Zuma made the decision to reshuffle the parliamentary cabinet, including the firing of finance minister, Pravin Gordhan. This decision was not well received by many South Africans.

Sample 2: President Zuma’s firing of popular finance minister, Gordhan drastically impacted investor confidence. This led to a sharp decrease in the value of the Rand. Such devaluation means that all USD-based imports (including petrol) will rise in cost, thereby raising the cost of living for South Africans, and reducing disposable income. This puts both cost and price pressure on Organisation X as an importer of USD-based goods Y, requiring it to consider doing Z. Furthermore, political instability has the added impact of encouraging immigration, particularly amongst skilled workers whose expertise is valued abroad (brain drain).

[Source: Jansen, 2017, Analytical Writing vs Descriptive Writing ]

Further, to write critically, you also have to pay attention to the rhetorical and logical aspects of writing:

Writing critically involves:

• Providing appropriate and sufficient arguments and examples
• Choosing terms that are precise, appropriate, and persuasive
• Making clear the transitions from one thought to another to ensure the overall logic of the presentation
• Editing for content, structure, and language

An increased awareness of the impact of choices of content, language, and structure can help you as a writer to develop habits of rewriting and revision.

Regarding the content, when writing critically, you cannot just rely on your own ideas, experiences, and/or one source. You have to read a wide range of sources on the specific topic you are exploring to get a holistic picture of what others have discussed on the topic, from which you further make your own judgment. Through reading other sources, you not only form your own judgment and opinions but also collect evidence to support your arguments. Evidence is so important in critical writing. In addition to the collection of evidence, you also need to use different ways (e.g., quoting, paraphrasing, and synthesizing) to integrate the evidence into your writing to increase your critical analysis.

Using quotes is always an issue. Some students like to quote a lot and/or too long throughout their papers, and others do not know why they quote. Remember that when you use direct quotations, you are using others’ ideas, not yours. You should limit the use of quotes to the minimum because readers are always interested in your opinions. In other words, you need to use quotes critically.

When you quote directly from a source, use the quotation critically. This means that you should not substitute the quotation for your own articulation of a point. Rather, introduce the quotation by laying out the judgments you are making about it, and the reasons why you are using it. Often a quotation is followed by some further analysis.

[Source: Knott , n.d., Critical Reading Towards Critical Writing ]

Barna (2017) stated that “A good rule of thumb is that the evidence should only be about 5-10% of the piece.” Further, according to the EAP Foundation.org , you need to avoid doing a laundry list in critical writing:

You cannot just string quotes together (A says this, B says that, C says something else), without looking more deeply at the information and building on it to support your own argument.

This means you need to break down the information from other sources to determine how the parts relate to one another or to an overall structure or purpose [analysing], and then make judgements about it, identifying its strengths and weaknesses, and possibly ‘grey areas’ in between, which are neither strengths nor weaknesses [evaluating]. Critical reading skills will help you with this, as you consider whether the source is reliable, relevant, up-to-date, and accurate.

When and Why do you quote?

When should you use quotes?

Using quotations is the easiest way to include source material, but quotations should be used carefully and sparingly. While paraphrasing and summarizing provide the opportunity to show your understanding of the source material, quoting may only show your ability to type it.

Having said that, there are a few very good reasons that you might want to use a quote rather than a paraphrase or summary:

• Accuracy: You are unable to paraphrase or summarize the source material without changing the author’s intent.
• Authority: You may want to use a quote to lend expert authority for your assertion or to provide source material for analysis.
• Conciseness: Your attempts to paraphrase or summarize are awkward or much longer than the source material.
• Unforgettable language: You believe that the words of the author are memorable or remarkable because of their effectiveness or historical flavor. Additionally, the author may have used a unique phrase or sentence, and you want to comment on words or phrases themselves.

When you decide to quote, be careful of relying too much upon one source or quoting too much of a source and make sure that your use of the quote demonstrates an understanding of the source material. Essentially, you want to avoid having a paper that is a string of quotes with occasional input from you.

[Source: Decide when to Quote, Paraphrase and Summarize ]

How do you quote?

• With a complete sentence
• With “according to”
• With a reporting verb
• With a “that” clause
• As part of your sentence

Citing the islands of Fiji as a case in point, Bordo notes that “until television was introduced in 1995, the islands had no reported cases of eating disorders. In 1998, three years after programs from the United States and Britain began broadcasting there, 62 percent of the girls surveyed reported dieting” (149-50). Bordo’s point is that the Western cult of dieting is spreading even to remote places across the globe.

[Source: Lane, 2020, Quoting: When and How to Use Quotations ]

The firm belief which has been widely advertised is that “international students should be given equal rights and respect while studying abroad” (Lane, 2020, p. 19).

Smith, an agent working at an international company, put forward the seriousness of economic recession brought by the COVID-19 pandemic: “our economy will soon collapse, followed by business failures, elevated unemployment, and social turbulence ” (2021, p. 87).

Dominguez (2002) suggested, “teachers should reflect on their teaching constantly and proactively” to avoid teacher burnout and attrition (pp. 76-79).

According to the IEP student manual, “To study in the IEP you must be 18 years old and your English level must be ‘high beginner’ or higher” (p. 6).

[Source: Five Ways to Introduce Quotations ]

Now move on to the language aspect of critical writing, you should pay attention to the analytical verbs used in critical writing.

Analytical verbs are verbs that indicate critical thinking. They’re used in essays to dissect a text and make interpretive points, helping you to form a strong argument and remain analytical. If you don’t use analytical verbs, you may find yourself simply repeating plot points, and describing a text, rather than evaluating and exploring core themes and ideas.

[Source: What are Analytical Verbs? ]

The use of analytical verbs is also important to show your precision and appropriateness in language use. For example, instead of using says and talks, replace those verbs with states, discusses, or claims. Not only does it enhance the formality of the language, but also it helps to create the tone of writing. This further means that you have to understand the specific meaning, purpose, and function of each verb in a specific context as shown in the table below.

[Source: Impressive Verbs to use in your Research Paper ]

The verbs listed under each category are NOT synonyms and are different based on context. Please ensure that the selected verb conveys your intended meaning.

It is recommended that you check out Academic Phrasebank for more advanced and critical language use.

The accuracy of language use that is important for critical writing is also reflected in the use of hedges .

Hedging is the use of linguistic devices to express hesitation or uncertainty as well as to demonstrate politeness and indirectness.

People use hedged language for several different purposes but perhaps the most fundamental are the following:

• to minimize the possibility of another academic opposing the claims that are being made
• to conform to the currently accepted style of academic writing
• to enable the author to devise a politeness strategy where they are able to acknowledge that there may be flaws in their claims

[Source: What Is Hedging in Academic Writing?]

There are different types of hedges used in writing to make your claim less certain but more convincing. For example, what is the difference between the two sentences as shown below?

No hedging: We already know all the animals in the world.

With hedging: It’s possible that we may already know most animals in the world.

[Source: Hedges and Boosters ]

Check this table for different types of hedges.

[Source: Features of academic writing]

Practice how to tone down the arguments.

ACTIVITY #2

Add hedges to the following arguments.

Except for the content and language aspects of critical writing, the last aspect is the organization, including both the overall structure and the paragraph level.

Here is one example of a critical writing outline.

One easy-to-follow outline format is alphanumeric, which means it uses letters of the alphabet and numbers to organize text.

For example:

• Hook: _____________________
• Transition to thesis: _____________________
• Thesis statement with three supporting points:_____________________
• Topic sentence: _____________________
• Evidence (data, facts, examples, logical reasoning): _____________________
• Connect evidence to thesis: _____________________
• Restate thesis: _____________________
• Summarize points: _____________________
• Closure (prediction, comment, call to action): _____________________

[Source: Academic Writing Tip: Making an Outline ]

1. Introduction

• Thesis statement

2. Topic one

• First piece of evidence
• Second piece of evidence

3. Topic two

4. Topic three

5. Conclusion

• Summary/synthesis
• Importance of topic
• Strong closing statement

ACTIVITY #3:

The following essay was adapted from a student’s writing. Please identify the components of each paragraph.

Artificial Intelligence: An Irreplaceable Assistant in Policy-making

Do you understand artificial intelligence (AI)? Are you excited that humans can create these machines that think like us? Do you ever worry that they develop too advanced to replace humans? If you have thought about these questions, you are already in the debate of the century. AI is a term used to describe machine artifacts with digital algorithms that have the ability to perceive contexts for action and the capacity to associate contexts to actions (Bryson & Winfield, 2017). The 21st century has witnessed a great number of changes in AI. As AI shows its great abilities in decision-making, humans are relying more on AI to make policies. Despite some concerns about the overuse of AI, AI is no longer to be replaced in policy-making because it has the capabilities that humans cannot achieve, such as transparent decision-making and powerful data processing.

AI has the capacity to use algorithms or systems to make the decision-making process more transparent (Walport & Sedwill, 2016). Many decisions made by humans are based upon their intuition rather than the direct result of the deliberate collection and processing of information (Dane et al., 2012). Intuition is useful in business when considering the outcome of an investment or a new product. However, in politics, the public would often question whether the policy is biased, so a transparent decision-making process should be used instead of intuition. AI can make political decisions more transparent by visualizing digital records (Calo, 2017). AI can make decisions without any discrimination and can have the public better understand of the policies.

In addition, AI can process a large amount of information at a speed faster than the cognitive ability of the most intelligent human policymakers (Jarrahi, 2018). A qualified policy must be based on facts reflected by data, so researching data is an essential part of policy-making. There are two main challenges for the human decision-makers in this area: (1) The amount of data is too large and (2) the relationship between data is too complex. Handling these two problems is where AI is superior. The high computing power of AI makes it an effective tool for retrieving and analyzing large amounts of data, thus reducing the complexity of the logic between problems (Jarrahi, 2018). Without AI, the policymakers would be overwhelmed by tons of data in this modern information age. It is almost impossible for them to convert those data into useful information. For example, data provided to the politician who is responsible for health care is mostly from the electronic health record (HER). HER is just the digital record transported from paper-based forms (Bennett et al., 2012). AI can analyze the data to generate clinical assessments, symptoms, and patient behavior and then link that information with social factors such as education level and economic status. According to the information from AI, the policy maker can make policies for healthcare improvement (Bennett et al., 2012). With the assistance of AI, the government can not only collect data easier but also utilize those data as operable Information.

However, while AI shows its great abilities in policy-making, it also brings considerable risks to contemporary society, and the most significant one is privacy. The only source for AI systems to learn human behavior is data, so AI needs to collect enormous quantities of information about users in order to perform better. Some scholars claim that the main problem with AI data collection is the use of data for unintended purposes. The data is likely to be processed, used, or even sold without the users’ permission (Bartneck et al, 2021). The 2018 Cambridge Analytica scandal showed how private data collected through Facebook can be used to manipulate elections (Bartneck et al, 2021). While privacy is a crucial problem, this is a handleable problem and we cannot deny the benefits brought by using AI. The most appropriate way to solve this problem is to establish a complete regulatory system. In fact, many policies have been made to protect user privacy in AI data collection. One of safeguard in this area is to restrict the centralized processing of data. Researchers are also conducting a lot of research in this area and have achieved some technological breakthroughs. For example, open-source code and open data formats will allow a more transparent distinction between private and transferable information, blockchain-based technologies will allow data to be reviewed and tracked, and “smart contracts” will provide transparent control over how data is used without the need for centralized authority (Yuste & Goering, 2017).

In conclusion, although there may be some privacy-related issues with AI policies, the powerful data collection capabilities and transparent decision-making process of AI will bring many benefits to humans. In the future, AI is more likely to continue to serve as an assistant to humans when making policies under a complete and strict regulatory system.

Apart from the overall structure of critical writing, it is also important to pay attention to the paragraph-level structure. There are different paragraph models for critical writing.

Model 1: TED model for writing critical paragraphs

Paragraph model for critical writing

Often in assignments, you are expected to critically evaluate – this means to assess the relevance and significance of concepts relating to a specific topic or assignment question. Introduce your point. Give examples from reading. Is there support for your argument or can you identify weaknesses? Are there different perspectives to compare and contrast? Build your explanation and create your objective, reasoned argument (case or thesis) based on the evaluation from different perspectives. You will include your conclusion and point of view, communicating your stance, having made a judgment on research you have found and its significance in contributing to answering your assignment question.

Use the TED model to integrate critical thinking into your writing:

Each example of evidence in your writing should have a clear purpose or function. Be explicit and tell the reader what it contributes to your reasoning.

Professional practice is more complex than simply applying theory to practice, since it involves a professional juggling of situational demands, intuition, experiences and knowledge (Schön, 1991). Practitioners do not apply research findings in a simple deductive process; they need time to think, translate and relate the research findings to their particular setting. The extent to which a given piece of evidence is utilised by an individual in practice depends on their sense of the situation and this inevitably involves professional judgement.

Model 2: WEED model for writing critical paragraphs

This is a model for writing critical paragraphs. It’s taken from Godwin’s book called ‘Planning your Essay’. Each paragraph should be on a single topic, making a single point. A paragraph is usually around a third of a page.

W is for What

You should begin your paragraph with the topic or point that you’re making so that it’s clear to your lecturer. Everything in the paragraph should fit in with this opening sentence.

E is for Evidence

The middle of your paragraph should be full of evidence – this is where all your references should be incorporated. Make sure that your evidence fits in with your topic.

E is for Examples

Sometimes it’s useful to expand on your evidence. If you’re talking about a case study, the example might be how your point relates to the particular scenario being discussed.

D is for Do

You should conclude your paragraph with the implications of your discussion. This gives you the opportunity to add your commentary, which is very important in assignments that require you to use critical analysis. So, in effect, each paragraph is like a mini-essay, with an introduction, main body, and conclusion.

Example: a good critical paragraph

Exposure to nature and green spaces has been found to increase health, happiness, and wellbeing. Whilst trees and greenery improve air quality by reducing air pollutants, green spaces facilitate physical activity, reduce stress, and provide opportunities for social interaction (Kaplan, 1995; Lachowycz,and Jones, 2011; Ward Thompson et al., 2012; Hartig et al., 2014; Anderson et al., 2016). Older adults have described increased feelings of wellbeing while spending time in green spaces and walking past street greenery (Finaly et al., 2015; Orr et al., 2016). They are more likely to walk on streets which are aesthetically pleasing (Lockett, Willis and Edwards, 2005) while greenery such as flowers and trees play an important role in improving the aesthetics of the environment (Day, 2008). Therefore, greater integration of urban green spaces and street greenery in cities may have the potential to increase physical activity and wellbeing in older adults.

Please identify the paragraph-level components in the following paragraphs. You can use different colors to indicate different components.

Social Media plays a key role in slowing the spread of vaccine misinformation. According to Nikos-Rose (2021) from the University of California, individuals’ attitudes towards vaccination can negatively be influenced by social media. They can simply post a piece of misleading information to the public, and the deceived ones will share it with their families and friends. The role of media can also help boost the public’s confidence in the vaccination. The media can provide valuable information for the public to know that the vaccine is safe. Almost everyone in the modern era lives with a cell phone now. People on social media can also share their experiences after getting vaccinated. Influences can help boost the public’s confidence. Just as voters would receive “I voted” after casting their ballots, vaccination distribution sites can provide “I got vaccinated” stickers. This can encourage individuals to post on the media that they have received the vaccine (Milkman, 2020). Furthermore, those who spread misleading information should be fined by the authorities. This punishment would be sufficient for them to learn their lesson. People who oversee data and information in social media should be concerned about the spread of misleading information on social media. After deleting the false information, they should put up a notice stating that is fake. This will help the public to understand which information should be trusted or not. Moreover, people who find misleading information online should report it to the administration. This could help prevent false info from circulating on the internet.

Recent studies showed that the contamination of land and water can also negatively affect the production of crops and the food systems as the safety of products can be compromised by the chemicals used by fracking. In addition, the amount of freshwater required for the mixture of the fracking fluids can generate a lack of water supply to the local agricultural industries. The fresh water is the 90-97 % of the fracking fluids, and the water deployed is not possible to recycle efficiently. In fact, the wastewater became a further challenge to the agricultural sector as it can make the soil dry and unusable for crops (Pothukuchi et al. 2018). The challenges faced by the agricultural sector are reflected in the farmlands and livestocks as well. For example, in Pennsylvania, the Dairy farming is one of the major agricultural sectors. This particular sector requires unpolluted water and pasturelands to enable the cows to produce milk. Since 1996 this sector began to fail, but the largest decrease in cows that produce milk took place between 2007 and 2011. It was the exact same period when the fracking industries reached their peak in this area (Pothukuchi et al. 2018). Another piece of evidence is related to the air pollution caused by fracking, specifically, the pollution of agricultural pollinators such as bees. The population of air caused by fracking has led to a huge degradation of that volatiles endangering the local and global food production. Those outcomes are closely related to the low level of planning abilities in rural areas, where fracking usually takes place. Particularly, the gap between fracking industry actors and local officials didn’t allow the development of a proper level of policies and regulations.

8 Of The Most Important Critical Thinking Skills

The most important critical thinking skills include analysis, synthesis, interpretation, inferencing, and judgement.

Critical thinking is the ongoing application of unbiased analysis in pursuit of objective truth.

Although its name implies criticism , critical thinking is actually closer to ‘ truth judgment ‘ based on withholding judgments while evaluating existing and emerging data to form more accurate conclusions. Critical thinking is an ongoing process emphasizing the fluid and continued interpretation of information rather than the formation of static beliefs and opinions.

Research about cognitively demanding skills provides formal academic content that we can extend to less formal settings, including K-12 classrooms.

This study , for example, explores the pivotal role of critical thinking in enhancing decision-making across various domains, including health, finance, and interpersonal relationships. The study highlights the significance of rigorous essential assessments of thinking, which can predict successful outcomes in complex scenarios.

Of course, this underscores the importance of integrating critical thinking development and measurement into educational frameworks to foster higher-level cognitive abilities impact real-world problem-solving and decision-making.

Which critical thinking skills are the most important?

Deciding which critical thinking skills are ‘most important’ isn’t simple because prioritizing them in any kind of order is less important than knowing what they are and when and how to use them.

However, to begin a process like that, it can be helpful to identify a small sample of the larger set of thinking processes and skills that constitute the skill of critical thinking.

Let’s take a look at eight of the more important, essential critical thinking skills everyone–students, teachers, and laypersons–should know.

8 Critical Thinking Skills Everyone Should Know

8 Essential Critical Thinking Skills

Analyze : break a whole into parts to examine.

Example: A teacher asks students to break down a story into its basic components: characters, setting, plot, conflict, and resolution. This helps students understand how each part contributes to the overall narrative.

Evaluate : Assess the value or quality

Example: A teacher prompts students to evaluate the effectiveness of two persuasive essays. Students assess which essay presents stronger arguments and why, considering factors like evidence, tone, and logic.

Interpret ” Explain the meaning or significance

Example: After reading a poem, the teacher asks students to interpret the symbolism of a recurring image, such as a river, discussing what it might represent in the poem’s context.

Synthesize ” Combine to form a coherent whole

Example: A teacher asks students to write an essay combining information from multiple sources about the causes of the American Revolution, encouraging them to create a cohesive argument that integrates diverse perspectives.

Infer : Draw conclusions based on evidence

Example: A teacher presents students with a scenario in a science experiment and asks them to infer what might happen if one variable is changed, based on the data they’ve already gathered.

Formal or informal inquiries to understand

Example: During a history lesson, the teacher encourages students to ask questions about the motivations of historical figures, prompting deeper understanding and critical discussions about historical events.

Reflect 

Recall and interpret experiences or ideas

Example: After completing a group project, a teacher asks students to reflect on what worked well and what could have been improved, helping them gain insights into their collaborative process and learning experience.

Judge : Form an opinion or conclusion

Example: A teacher presents students with a scenario where two solutions are proposed to solve a community issue, such as building a new park or a community center. The teacher asks students to use their judgment to determine which solution would best meet the community’s needs, considering cost, accessibility, and potential benefits.
