More About Thesis Statement
What is a thesis statement .
In academic writing, a thesis statement is generally a sentence or two that summarizes the main point that an essay, research paper, or speech is making. It is typically located at the end of the introductory paragraph(s).
Thesis statements are kind of like roadmaps, laying out for the reader/listener where the writer/speaker is headed (argument) and how they are going to get there (evidence).
The thesis statement is widely taught in the humanities, especially in English classes in high school and college, to teach students how to make persuasive arguments that cite and analyze evidence and examples researched from literary, historical, or other texts.
Why is a thesis statement important in an essay?
Thesis comes from a Greek word that literally means “a setting down.” In the 300s BC, Aristotle defined thesis as when a philosopher puts forth a new idea that conflicts with general opinion.
Fast forward to today, when we use thesis to mean a “proposition” or “argument” one formally presents and defends. In academic settings, a thesis can be short for a thesis statement (our focus here) in an essay or shorter research paper. It can also be used for those much, much longer dissertations graduate students research, write, and defend for their degree (e.g., master’s thesis or doctoral thesis ).
Let’s look at statement real quick. It is a declaration or assertion. Sound redundant? The idea is that a thesis statement is the point in a paper or presentation that explicitly states the thesis. Usually in a sentence or two, the thesis statement summarizes the argument that’s going to be developed in the evidence and examples to come.
So, a thesis statement is just a sentence that gets the main point across. But, learning how to write these ain’t easy. That’s why educators, especially in English classes in high school and college, spend a lot of time teaching students how to craft effective thesis statements.
Why? Because in school, work, and life, we have to persuade people of our ideas and our point of view. These ideas might concern an analysis of literature or history, like a play by Shakespeare or a moment in the Civil Rights Movement. Or, these ideas might be a call to action, such as eating a certain diet or pursuing a business strategy.
How to write a thesis statement
There are many ways to make an effective thesis statement , but here are some general tips to follow.
So, let’s say you read a text, Shakespeare’s Twelfth Night , or researched a topic, the health benefits of kale. Then you formed an opinion about it—a claim you want to make about it and why others should care. You found evidence—quotes, examples, facts, statistics—in your resources that you think back up your argument. Your thesis statement brings all these together: point of view , evidence , and significance . It lays out where the entire paper or presentation is going, which is why educators often liken it to a roadmap .
Here’s an example:
Kale is good for you because it is nutrient-dense, cancer-fighting, and loaded with antioxidants.
The argument here—which a first-year high-schooler might make in a persuasive essay—is that “kale is good for you” (despite how some think it tastes). The claims it’s using to back up this assertion are that it’s 1) “nutrient-dense”; 2) “cancer-fighting”; and 3) “loaded with antioxidants.” The reader can expect that the rest of the essay will develop these claims, that is, cite and analyze evidence for them.
Here’s a thesis statement for a literary analysis of Shakespeare’s Twelfth Night. This resembles more of a college-level example:
Shakespeare’s Twelfth Night suggests that, when women do not reciprocate a man’s love, they are unjustly made out to be sexually deviant. This is illustrated in how the character Olivia is condemned as asexual because of her rejection of Duke Orsino.
Note how this thesis statement makes its claim in two sentences. Its argument centers on how women characters are vilified when they reject a man, and its evidence will be interactions between characters in Shakespeare’s play.
What are real-life examples of thesis statement ?
The term thesis statement is generally used by teachers and students in junior high, high school, and college, especially in English, Social Studies, and other classes in the humanities.
Okay so I rewrote my thesis statement! It’s a wee bit more vague but still a good direction a think. It’s more open so I can talk about more things and add more evidence. Wrote out an in-depth plan and then my brain crapped out. So I’m going to bed! Tomorrow is the day! — 🎃Unpaid Bills🎃 //Chaela (@Cierafire) August 14, 2019
Writing an explanatory essay in phases: thesis statement, body paragraph, concluding statement. Peer conversations to identify text evidence to support our thesis. pic.twitter.com/b6fdgx8rkD — Cheyenne England (@MsEnglandReads) August 7, 2019
The thesis statement is taught in what’s called the five-paragraph essay (or theme). This essay has an introduction which “funnels into” the thesis statement, including three reasons backing up the main argument. The next three paragraphs develop each of these claims, respectively, citing evidence and examples, such as literary texts, historical documents, or scientific reports. The final paragraph, the conclusion, restates the thesis statement and summarizes the paper and its broader significance.
Opentextbc.ca
Even after we are no longer in the classroom, people continue to reference thesis statements. While “real-life” thesis statements may not be as formal as the ones seen in five-paragraph essays, having a thesis statement —a point, a position, or a theory of the case—is considered informative, persuasive, and valuable in work, in the community, and in our personal lives.
The thesis statement is so widely taught and familiar that sometimes people joke about them. On social media, for instance, people may humorously end a post with “In this essay, I will …” when expressing a deeply felt but ultimately low-stakes opinion on some popular topic. The phrase In this essay, I will alludes to the signposting language some people use in their thesis statements.

Thesis Statement
Definition of thesis statement.
A thesis statement is a statement that occurs at the end of the introduction , after the background information on the topic. The thesis statement is connected with the background information through a transition , which could be a full sentence , or a simple transition word, such as therefore, because, but etc.
The thesis statement is called the “heart of the essay .” The idea of an essay without a thesis statement is akin to a body without its heart. It also is called the “central point” or the “core” of an essay. It is comprised of evidences that the writer uses to elaborate on his topic further. Each of these evidences is then elaborated and discussed in the body paragraphs .
If there are three body paragraphs, the thesis statement must have three evidences, and should it have more than three body paragraphs, may be additional evidences. In argumentative essays, three evidences support the topic, while the fourth evidence is against it. The same is the case of persuasive essays. This applies to five-paragraph essays, but in case of a longer essay, the thesis statement could make use of more than one sentence.
There is a slight controversy over the placement of a thesis statement. Some writers and professors argue that it could be placed in the first paragraph at the end, while others feel that, in longer essays, it is not possible to give background information in just one paragraph. As background information takes two or three paragraphs, the thesis statement is kept slightly larger, having two or three sentences, and is placed at the end of the second or third paragraph. However, in a five-paragraph essay, the thesis statement is always placed at the end of the introduction, after the background information.
Qualities of a Good Thesis Statement
- It must have evidences.
- It should be interesting.
- It should be limited.
- It should be manageable.
- It should be researchable.
Difference Between a Thesis Statement and Topic
Sometimes students confuse a thesis statement with a topic, mistaking the thesis statement as the very topic of the essay they are going to read. However, it must be kept in mind that a thesis statement is not a topic, but a brief explanation of the topic in a way that sets the direction of the essay. It predicts the path the essay will take, and tells readers how the essay is going to be organized, and what each part contains.
The topic, however, is a general idea of the essay. It is a specific topic, which has been organized by the thesis statement. The thesis statement in turn elaborates evidences to support to the topic.
Examples of Good and Bad Thesis Statements
- Bad Thesis Statement – “Social media is proving a good marketing tool.”
- Good Thesis Statement – “Social media is proving to be, not only a better marketing tool, but also a source of advertisement for short and medium enterprises intending to expand their consumer base.”
Examples of Thesis Statements in Literature
Example #1: dream on (by mark krikorian in national review online ).
“The core principal behind this amnesty proposal is that it is amid at those who have grown up here and are, psychologically and emotionally, Americans.”
This is the first sentence of the second paragraph. The second sentence further elaborates this thesis. It is placed in the second paragraph because the first paragraph introduces the controversial DREAM Act. As the writer is going to argue against the bill, he has stated his argument as to why he is going to oppose it. This is a very compact thesis statement with various implicit counter arguments.
Example #2: Editorial (by The Washington Post)
“There is no doubt that the attacks profoundly affected our country’s policy, politics, economics, society and even collective psychology. Moreover, in addition to sharing the immediate experience of September 9/11, Americans have dealt with its consequences in the years since.”
This is the best thesis statement with clear evidences in it. It is not as complicated as other thesis statements usually are.
Example #3: I Have a Dream (by Martin Luther King)
“In a sense we’ve come to our nation’s capital to cash a check. When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir. This note was a promise that all men, yes, black men as well as white men, would be guaranteed the ‘unalienable Rights’ of ‘Life, Liberty and the pursuit of Happiness.’ It is obvious today that America has defaulted on this promissory note, insofar as her citizens of color are concerned. Instead of honoring this sacred obligation, America has given the Negro people a bad check, a check which has come back marked ‘insufficient funds’.”
This is one of the best examples of long thesis statements. It highlights what Martin Luther King is going to speak about. It comes after three paragraphs of background information.
Function of Thesis Statement
A good thesis statement is the heart of an essay. It gives a gist of the thoughts a writer expresses in his essay. It determines the shape of the essay, predicts its content, and foreshadows its events. It narrates the whole story in just one sentence, provided the essay is a short one. Without a thesis statement, an essay is just a written piece, not an organized and well-connected essay

Writing a Paper: Thesis Statements
Basics of thesis statements.
The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).
Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.
Being Specific
This thesis statement has no specific argument:
Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.
This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.
Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.
The new revision here is still concise, as well as specific and arguable. We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors. We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").
Making a Unique Argument
This thesis draft repeats the language of the writing prompt without making a unique argument:
Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.
You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.
Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).
Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.
Creating a Debate
This thesis statement includes only obvious fact or plot summary instead of argument:
Needs Improvement: Leadership is an important quality in nurse educators.
A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators. The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.
Better: Roderick's (2009) theory of participatory leadership is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.
Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.
Choosing the Right Words
This thesis statement uses large or scholarly-sounding words that have no real substance:
Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.
There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.
Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.
Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.
Leaving Room for Discussion
This thesis statement is not capable of development or advancement in the paper:
Needs Improvement: There are always alternatives to illegal drug use.
This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.
Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).
In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.
Thesis Mad Libs
If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.
- In this essay, I argue ____, using ______ to assert _____.
- While scholars have often argued ______, I argue______, because_______.
- Through an analysis of ______, I argue ______, which is important because_______.
Words to Avoid and to Embrace
When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.
Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

What is a thesis statement?
A thesis statement is an essential component of ALL academic and research writing.
A thesis statement:
- occurs early in a piece of written work (introduction)
- tells the reader what the purpose and scope of the work will be
- provides more than a mere description of the topic
- puts a ‘wager’ (i.e. a bet) on the topic by telling us what the significance of the research will be
- defines what will be investigated and what they think will be found (note, it’s OK if the hypothesis is disproven once the data is in)
Descriptive thesis statements
Beware thesis statements that are too descriptive because they “do not investigate anything, critique anything, or analyze anything […] they also do not invite support and argument from outside of the central text” ( UW Expository Writing Program, 2007, p. 2). The problem with thesis statements that are merely descriptive is that they lack a ‘stance’ or an argument. They are therefore difficult to support with evidence and to build an argument for.
The examples below would not make good thesis statements because they are too descriptive.
a) Shakespeare was a famous playwright during the Elizabethan era. He wrote numerous plays and poems.
b) Almost one in two marriages in Australia end in divorce. That means the divorce rate is almost 50%.
c) Covid-19 was a virus that caused an epidemic in the early 2020’s.
Check your understanding
Where is the thesis statement in the passage below?
My intention was to investigate and portray Antarctica through my own and others’ personal experiences, through historical examples of jewellery and souvenirs and through experimentation in the studio-based manufacture of new jewellery and souvenirs [e] . The objects produced through this research would reference the valued jewellery and souvenirs now displayed in museums as historical artefacts which were once personal mementos [f] . I was particularly interested in the potential of these objects to represent personal narratives and experiences of the past [g] . In this research project I have explored some of the ways in which I can make objects, specifically jewellery and souvenirs that draw on this rich heritage to present Antarctica in an innovative way [h] .

- When & How to Write a Thesis
I. What is a Thesis?
The thesis (pronounced thee -seez), also known as a thesis statement, is the sentence that introduces the main argument or point of view of a composition (formal essay, nonfiction piece, or narrative). It is the main claim that the author is making about that topic and serves to summarize and introduce that writing that will be discussed throughout the entire piece. For this reason, the thesis is typically found within the first introduction paragraph.
II. Examples of Theses
Here are a few examples of theses which may be found in the introductions of a variety of essays :
In “The Mending Wall,” Robert Frost uses imagery, metaphor, and dialogue to argue against the use of fences between neighbors.
In this example, the thesis introduces the main subject (Frost’s poem “The Mending Wall”), aspects of the subject which will be examined (imagery, metaphor, and dialogue) and the writer’s argument (fences should not be used).
While Facebook connects some, overall, the social networking site is negative in that it isolates users, causes jealousy, and becomes an addiction.
This thesis introduces an argumentative essay which argues against the use of Facebook due to three of its negative effects.
During the college application process, I discovered my willingness to work hard to achieve my dreams and just what those dreams were.
In this more personal example, the thesis statement introduces a narrative essay which will focus on personal development in realizing one’s goals and how to achieve them.
III. The Importance of Using a Thesis
Theses are absolutely necessary components in essays because they introduce what an essay will be about. Without a thesis, the essay lacks clear organization and direction. Theses allow writers to organize their ideas by clearly stating them, and they allow readers to be aware from the beginning of a composition’s subject, argument, and course. Thesis statements must precisely express an argument within the introductory paragraph of the piece in order to guide the reader from the very beginning.
IV. Examples of Theses in Literature
For examples of theses in literature, consider these thesis statements from essays about topics in literature:
In William Shakespeare’s “ Sonnet 46,” both physicality and emotion together form powerful romantic love.
This thesis statement clearly states the work and its author as well as the main argument: physicality and emotion create romantic love.
In The Scarlet Letter, Nathaniel Hawthorne symbolically shows Hester Prynne’s developing identity through the use of the letter A: she moves from adulteress to able community member to angel.
In this example, the work and author are introduced as well as the main argument and supporting points: Prynne’s identity is shown through the letter A in three ways: adulteress, able community member, and angel.
John Keats’ poem “To Autumn” utilizes rhythm, rhyme, and imagery to examine autumn’s simultaneous birth and decay.
This thesis statement introduces the poem and its author along with an argument about the nature of autumn. This argument will be supported by an examination of rhythm, rhyme, and imagery.
V. Examples of Theses in Pop Culture
Sometimes, pop culture attempts to make arguments similar to those of research papers and essays. Here are a few examples of theses in pop culture:
America’s food industry is making a killing and it’s making us sick, but you have the power to turn the tables.
The documentary Food Inc. examines this thesis with evidence throughout the film including video evidence, interviews with experts, and scientific research.
Orca whales should not be kept in captivity, as it is psychologically traumatizing and has caused them to kill their own trainers.
Blackfish uses footage, interviews, and history to argue for the thesis that orca whales should not be held in captivity.
VI. Related Terms
Just as a thesis is introduced in the beginning of a composition, the hypothesis is considered a starting point as well. Whereas a thesis introduces the main point of an essay, the hypothesis introduces a proposed explanation which is being investigated through scientific or mathematical research. Thesis statements present arguments based on evidence which is presented throughout the paper, whereas hypotheses are being tested by scientists and mathematicians who may disprove or prove them through experimentation. Here is an example of a hypothesis versus a thesis:
Hypothesis:
Students skip school more often as summer vacation approaches.
This hypothesis could be tested by examining attendance records and interviewing students. It may or may not be true.
Students skip school due to sickness, boredom with classes, and the urge to rebel.
This thesis presents an argument which will be examined and supported in the paper with detailed evidence and research.
Introduction
A paper’s introduction is its first paragraph which is used to introduce the paper’s main aim and points used to support that aim throughout the paper. The thesis statement is the most important part of the introduction which states all of this information in one concise statement. Typically, introduction paragraphs require a thesis statement which ties together the entire introduction and introduces the rest of the paper.
VII. Conclusion
Theses are necessary components of well-organized and convincing essays, nonfiction pieces, narratives , and documentaries. They allow writers to organize and support arguments to be developed throughout a composition, and they allow readers to understand from the beginning what the aim of the composition is.

How to write a thesis statement, what is a thesis statement.
Almost all of us—even if we don’t do it consciously—look early in an essay for a one- or two-sentence condensation of the argument or analysis that is to follow. We refer to that condensation as a thesis statement.
Why Should Your Essay Contain a Thesis Statement?
- to test your ideas by distilling them into a sentence or two
- to better organize and develop your argument
- to provide your reader with a “guide” to your argument
In general, your thesis statement will accomplish these goals if you think of the thesis as the answer to the question your paper explores.
How Can You Write a Good Thesis Statement?
Here are some helpful hints to get you started. You can either scroll down or select a link to a specific topic.
How to Generate a Thesis Statement if the Topic is Assigned How to Generate a Thesis Statement if the Topic is not Assigned How to Tell a Strong Thesis Statement from a Weak One
How to Generate a Thesis Statement if the Topic is Assigned
Almost all assignments, no matter how complicated, can be reduced to a single question. Your first step, then, is to distill the assignment into a specific question. For example, if your assignment is, “Write a report to the local school board explaining the potential benefits of using computers in a fourth-grade class,” turn the request into a question like, “What are the potential benefits of using computers in a fourth-grade class?” After you’ve chosen the question your essay will answer, compose one or two complete sentences answering that question.
Q: “What are the potential benefits of using computers in a fourth-grade class?” A: “The potential benefits of using computers in a fourth-grade class are . . .”
A: “Using computers in a fourth-grade class promises to improve . . .”
The answer to the question is the thesis statement for the essay.
[ Back to top ]
How to Generate a Thesis Statement if the Topic is not Assigned
Even if your assignment doesn’t ask a specific question, your thesis statement still needs to answer a question about the issue you’d like to explore. In this situation, your job is to figure out what question you’d like to write about.
A good thesis statement will usually include the following four attributes:
- take on a subject upon which reasonable people could disagree
- deal with a subject that can be adequately treated given the nature of the assignment
- express one main idea
- assert your conclusions about a subject
Let’s see how to generate a thesis statement for a social policy paper.
Brainstorm the topic . Let’s say that your class focuses upon the problems posed by changes in the dietary habits of Americans. You find that you are interested in the amount of sugar Americans consume.
You start out with a thesis statement like this:
Sugar consumption.
This fragment isn’t a thesis statement. Instead, it simply indicates a general subject. Furthermore, your reader doesn’t know what you want to say about sugar consumption.
Narrow the topic . Your readings about the topic, however, have led you to the conclusion that elementary school children are consuming far more sugar than is healthy.
You change your thesis to look like this:
Reducing sugar consumption by elementary school children.
This fragment not only announces your subject, but it focuses on one segment of the population: elementary school children. Furthermore, it raises a subject upon which reasonable people could disagree, because while most people might agree that children consume more sugar than they used to, not everyone would agree on what should be done or who should do it. You should note that this fragment is not a thesis statement because your reader doesn’t know your conclusions on the topic.
Take a position on the topic. After reflecting on the topic a little while longer, you decide that what you really want to say about this topic is that something should be done to reduce the amount of sugar these children consume.
You revise your thesis statement to look like this:
More attention should be paid to the food and beverage choices available to elementary school children.
This statement asserts your position, but the terms more attention and food and beverage choices are vague.
Use specific language . You decide to explain what you mean about food and beverage choices , so you write:
Experts estimate that half of elementary school children consume nine times the recommended daily allowance of sugar.
This statement is specific, but it isn’t a thesis. It merely reports a statistic instead of making an assertion.
Make an assertion based on clearly stated support. You finally revise your thesis statement one more time to look like this:
Because half of all American elementary school children consume nine times the recommended daily allowance of sugar, schools should be required to replace the beverages in soda machines with healthy alternatives.
Notice how the thesis answers the question, “What should be done to reduce sugar consumption by children, and who should do it?” When you started thinking about the paper, you may not have had a specific question in mind, but as you became more involved in the topic, your ideas became more specific. Your thesis changed to reflect your new insights.
How to Tell a Strong Thesis Statement from a Weak One
1. a strong thesis statement takes some sort of stand..
Remember that your thesis needs to show your conclusions about a subject. For example, if you are writing a paper for a class on fitness, you might be asked to choose a popular weight-loss product to evaluate. Here are two thesis statements:
There are some negative and positive aspects to the Banana Herb Tea Supplement.
This is a weak thesis statement. First, it fails to take a stand. Second, the phrase negative and positive aspects is vague.
Because Banana Herb Tea Supplement promotes rapid weight loss that results in the loss of muscle and lean body mass, it poses a potential danger to customers.
This is a strong thesis because it takes a stand, and because it's specific.
2. A strong thesis statement justifies discussion.
Your thesis should indicate the point of the discussion. If your assignment is to write a paper on kinship systems, using your own family as an example, you might come up with either of these two thesis statements:
My family is an extended family.
This is a weak thesis because it merely states an observation. Your reader won’t be able to tell the point of the statement, and will probably stop reading.
While most American families would view consanguineal marriage as a threat to the nuclear family structure, many Iranian families, like my own, believe that these marriages help reinforce kinship ties in an extended family.
This is a strong thesis because it shows how your experience contradicts a widely-accepted view. A good strategy for creating a strong thesis is to show that the topic is controversial. Readers will be interested in reading the rest of the essay to see how you support your point.
3. A strong thesis statement expresses one main idea.
Readers need to be able to see that your paper has one main point. If your thesis statement expresses more than one idea, then you might confuse your readers about the subject of your paper. For example:
Companies need to exploit the marketing potential of the Internet, and Web pages can provide both advertising and customer support.
This is a weak thesis statement because the reader can’t decide whether the paper is about marketing on the Internet or Web pages. To revise the thesis, the relationship between the two ideas needs to become more clear. One way to revise the thesis would be to write:
Because the Internet is filled with tremendous marketing potential, companies should exploit this potential by using Web pages that offer both advertising and customer support.
This is a strong thesis because it shows that the two ideas are related. Hint: a great many clear and engaging thesis statements contain words like because , since , so , although , unless , and however .
4. A strong thesis statement is specific.
A thesis statement should show exactly what your paper will be about, and will help you keep your paper to a manageable topic. For example, if you're writing a seven-to-ten page paper on hunger, you might say:
World hunger has many causes and effects.
This is a weak thesis statement for two major reasons. First, world hunger can’t be discussed thoroughly in seven to ten pages. Second, many causes and effects is vague. You should be able to identify specific causes and effects. A revised thesis might look like this:
Hunger persists in Glandelinia because jobs are scarce and farming in the infertile soil is rarely profitable.
This is a strong thesis statement because it narrows the subject to a more specific and manageable topic, and it also identifies the specific causes for the existence of hunger.

Writing a Thesis Statement — Definition, Types, and Examples
What is a thesis statement?
A thesis statement is a single sentence that identifies the topic and purpose of a scholarly research paper or academic writing. A thesis statement directly or indirectly presents the main points of the paper. Information presented in the essay should tie directly back to the thesis.
Overall, a good thesis statement accomplishes the following:
Identifies the purpose of the essay
Expresses the writer's position/opinion
Lists the main supports (optional)
Briefly summarizes the writer's conclusion(s)
Establish if the essay is explanatory, argumentative, or analytical
People often confuse thesis statements with topic sentences , which start each body paragraph. Typically, the thesis statement is the final sentence in the introductory paragraph and acts as a “road map” for the rest of the paper.
Types of thesis statements
The three main types of thesis statements are explanatory, argumentative, and analytical.
Explanatory thesis statements are used in expository essays that focus solely on informing the reader. Papers with this type of thesis do not contain the writer's opinion, nor do they try to persuade the reader.
The three main branches of science taught in public schools include biology, chemistry, and physics.
Argumentative thesis statements identify the writer's position or point of view on a given topic. Argumentative essays persuade the reader to agree with the writer's stance. If the reader cannot agree or disagree with the claim in the thesis, then it is not argumentative.
Public schools should place more emphasis on the arts because they encourage creativity, help improve academic development, and provide a beneficial emotional outlet.
Analytical thesis statements are used in papers that analyze how or why something does what it does. These thesis statements identify what the writer is analyzing, the parts of the analysis, and the order of those parts.
An analysis of course requirements in public schools suggests access to more electives can increase graduation rates.
How to write a thesis statement
When writing a thesis, the following guidelines apply:
Step 1: Determine the type of paper (explanatory, argumentative, or analytical).
Step 2: Identify the topic, position/claim, and supports of the essay.
Step 3: Determine if the supports should be included within the thesis. Although they are considered optional, they might be required depending on the audience and purpose of the essay.
Step 4: Compose a sentence that includes the topic, position, and supports (optional). While a thesis statement can be more than one sentence, it should not exceed two.
Step 5: Place the thesis statement at the end of the introductory paragraph(s). Placing it at the end of the introduction and before the supports allows the reader to focus on the paper’s main purpose.
Thesis statement examples
The following examples highlight each type of thesis statement.
Topic: Alternative Energy Sources
Explanatory Thesis: Alternative energy sources that can supplement the use of fossil fuels include solar, wind, and geothermal.
Argumentative Thesis: To combat reliance on foreign sources of fossil fuels, the United States would benefit from focusing on alternative energy options.
Analytical Thesis: Analysis suggests that replacing fossil fuels with alternative energy sources could negatively impact the economy.
Topic: Social Media
Explanatory Thesis: Three of the first platforms that influenced the world of social media include Facebook, Twitter, and Instagram.
Argumentative Thesis: Social media negatively influences society as it increases opportunities for cyberbullying, limits face-to-face interactions, and creates unrealistic expectations.
Analytical Thesis: An analysis of the use of social media suggests itis irrevocably harming the development of teenagers.
Topic: Standardized Testing
Explanatory Thesis: Standardized tests such as the ACT and SAT play a limited role in influencing college acceptance.
Argumentative Thesis: Standardized testing should not be required because it increases anxiety, does not measure progress, and cannot predict future success.
Analytical Thesis: Analysis suggests that standardized testing in elementary and high school negatively impacts students' academic success.
Think of yourself as a member of a jury, listening to a lawyer who is presenting an opening argument. You'll want to know very soon whether the lawyer believes the accused to be guilty or not guilty, and how the lawyer plans to convince you. Readers of academic essays are like jury members: before they have read too far, they want to know what the essay argues as well as how the writer plans to make the argument. After reading your thesis statement, the reader should think, "This essay is going to try to convince me of something. I'm not convinced yet, but I'm interested to see how I might be."
An effective thesis cannot be answered with a simple "yes" or "no." A thesis is not a topic; nor is it a fact; nor is it an opinion. "Reasons for the fall of communism" is a topic. "Communism collapsed in Eastern Europe" is a fact known by educated people. "The fall of communism is the best thing that ever happened in Europe" is an opinion. (Superlatives like "the best" almost always lead to trouble. It's impossible to weigh every "thing" that ever happened in Europe. And what about the fall of Hitler? Couldn't that be "the best thing"?)
A good thesis has two parts. It should tell what you plan to argue, and it should "telegraph" how you plan to argue—that is, what particular support for your claim is going where in your essay.
Steps in Constructing a Thesis
First, analyze your primary sources. Look for tension, interest, ambiguity, controversy, and/or complication. Does the author contradict himself or herself? Is a point made and later reversed? What are the deeper implications of the author's argument? Figuring out the why to one or more of these questions, or to related questions, will put you on the path to developing a working thesis. (Without the why, you probably have only come up with an observation—that there are, for instance, many different metaphors in such-and-such a poem—which is not a thesis.)
Once you have a working thesis, write it down. There is nothing as frustrating as hitting on a great idea for a thesis, then forgetting it when you lose concentration. And by writing down your thesis you will be forced to think of it clearly, logically, and concisely. You probably will not be able to write out a final-draft version of your thesis the first time you try, but you'll get yourself on the right track by writing down what you have.
Keep your thesis prominent in your introduction. A good, standard place for your thesis statement is at the end of an introductory paragraph, especially in shorter (5-15 page) essays. Readers are used to finding theses there, so they automatically pay more attention when they read the last sentence of your introduction. Although this is not required in all academic essays, it is a good rule of thumb.
Anticipate the counterarguments. Once you have a working thesis, you should think about what might be said against it. This will help you to refine your thesis, and it will also make you think of the arguments that you'll need to refute later on in your essay. (Every argument has a counterargument. If yours doesn't, then it's not an argument—it may be a fact, or an opinion, but it is not an argument.)
This statement is on its way to being a thesis. However, it is too easy to imagine possible counterarguments. For example, a political observer might believe that Dukakis lost because he suffered from a "soft-on-crime" image. If you complicate your thesis by anticipating the counterargument, you'll strengthen your argument, as shown in the sentence below.
Some Caveats and Some Examples
A thesis is never a question. Readers of academic essays expect to have questions discussed, explored, or even answered. A question ("Why did communism collapse in Eastern Europe?") is not an argument, and without an argument, a thesis is dead in the water.
A thesis is never a list. "For political, economic, social and cultural reasons, communism collapsed in Eastern Europe" does a good job of "telegraphing" the reader what to expect in the essay—a section about political reasons, a section about economic reasons, a section about social reasons, and a section about cultural reasons. However, political, economic, social and cultural reasons are pretty much the only possible reasons why communism could collapse. This sentence lacks tension and doesn't advance an argument. Everyone knows that politics, economics, and culture are important.
A thesis should never be vague, combative or confrontational. An ineffective thesis would be, "Communism collapsed in Eastern Europe because communism is evil." This is hard to argue (evil from whose perspective? what does evil mean?) and it is likely to mark you as moralistic and judgmental rather than rational and thorough. It also may spark a defensive reaction from readers sympathetic to communism. If readers strongly disagree with you right off the bat, they may stop reading.
An effective thesis has a definable, arguable claim. "While cultural forces contributed to the collapse of communism in Eastern Europe, the disintegration of economies played the key role in driving its decline" is an effective thesis sentence that "telegraphs," so that the reader expects the essay to have a section about cultural forces and another about the disintegration of economies. This thesis makes a definite, arguable claim: that the disintegration of economies played a more important role than cultural forces in defeating communism in Eastern Europe. The reader would react to this statement by thinking, "Perhaps what the author says is true, but I am not convinced. I want to read further to see how the author argues this claim."
A thesis should be as clear and specific as possible. Avoid overused, general terms and abstractions. For example, "Communism collapsed in Eastern Europe because of the ruling elite's inability to address the economic concerns of the people" is more powerful than "Communism collapsed due to societal discontent."

Definition of thesis
Did you know.
In high school, college, or graduate school, students often have to write a thesis on a topic in their major field of study. In many fields, a final thesis is the biggest challenge involved in getting a master's degree, and the same is true for students studying for a Ph.D. (a Ph.D. thesis is often called a dissertation ). But a thesis may also be an idea; so in the course of the paper the student may put forth several theses (notice the plural form) and attempt to prove them.
