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.

Thesis statement

What is a thesis statement?

Is a thesis statement a question, how do you write a good thesis statement, how do i know if my thesis statement is good, examples of thesis statements, helpful resources on how to write a thesis statement, frequently asked questions about writing a thesis statement, related articles.

A thesis statement is the main argument of your paper or thesis.

The thesis statement is one of the most important elements of any piece of academic writing . It is a brief statement of your paper’s main argument. Essentially, you are stating what you will be writing about.

You can see your thesis statement as an answer to a question. While it also contains the question, it should really give an answer to the question with new information and not just restate or reiterate it.

Your thesis statement is part of your introduction. Learn more about how to write a good thesis introduction in our introduction guide .

A thesis statement is not a question. A statement must be arguable and provable through evidence and analysis. While your thesis might stem from a research question, it should be in the form of a statement.

Tip: A thesis statement is typically 1-2 sentences. For a longer project like a thesis, the statement may be several sentences or a paragraph.

A good thesis statement needs to do the following:

  • Condense the main idea of your thesis into one or two sentences.
  • Answer your project’s main research question.
  • Clearly state your position in relation to the topic .
  • Make an argument that requires support or evidence.

Once you have written down a thesis statement, check if it fulfills the following criteria:

  • Your statement needs to be provable by evidence. As an argument, a thesis statement needs to be debatable.
  • Your statement needs to be precise. Do not give away too much information in the thesis statement and do not load it with unnecessary information.
  • Your statement cannot say that one solution is simply right or simply wrong as a matter of fact. You should draw upon verified facts to persuade the reader of your solution, but you cannot just declare something as right or wrong.

As previously mentioned, your thesis statement should answer a question.

If the question is:

What do you think the City of New York should do to reduce traffic congestion?

A good thesis statement restates the question and answers it:

In this paper, I will argue that the City of New York should focus on providing exclusive lanes for public transport and adaptive traffic signals to reduce traffic congestion by the year 2035.

Here is another example. If the question is:

How can we end poverty?

A good thesis statement should give more than one solution to the problem in question:

In this paper, I will argue that introducing universal basic income can help reduce poverty and positively impact the way we work.

  • The Writing Center of the University of North Carolina has a list of questions to ask to see if your thesis is strong .

A thesis statement is part of the introduction of your paper. It is usually found in the first or second paragraph to let the reader know your research purpose from the beginning.

In general, a thesis statement should have one or two sentences. But the length really depends on the overall length of your project. Take a look at our guide about the length of thesis statements for more insight on this topic.

Here is a list of Thesis Statement Examples that will help you understand better how to write them.

Every good essay should include a thesis statement as part of its introduction, no matter the academic level. Of course, if you are a high school student you are not expected to have the same type of thesis as a PhD student.

How to Write a Strong Thesis Statement: 4 Steps + Examples

good thesis for a essay

What’s Covered:

What is the purpose of a thesis statement, writing a good thesis statement: 4 steps, common pitfalls to avoid, where to get your essay edited for free.

When you set out to write an essay, there has to be some kind of point to it, right? Otherwise, your essay would just be a big jumble of word salad that makes absolutely no sense. An essay needs a central point that ties into everything else. That main point is called a thesis statement, and it’s the core of any essay or research paper.

You may hear about Master degree candidates writing a thesis, and that is an entire paper–not to be confused with the thesis statement, which is typically one sentence that contains your paper’s focus. 

Read on to learn more about thesis statements and how to write them. We’ve also included some solid examples for you to reference.

Typically the last sentence of your introductory paragraph, the thesis statement serves as the roadmap for your essay. When your reader gets to the thesis statement, they should have a clear outline of your main point, as well as the information you’ll be presenting in order to either prove or support your point. 

The thesis statement should not be confused for a topic sentence , which is the first sentence of every paragraph in your essay. If you need help writing topic sentences, numerous resources are available. Topic sentences should go along with your thesis statement, though.

Since the thesis statement is the most important sentence of your entire essay or paper, it’s imperative that you get this part right. Otherwise, your paper will not have a good flow and will seem disjointed. That’s why it’s vital not to rush through developing one. It’s a methodical process with steps that you need to follow in order to create the best thesis statement possible.

Step 1: Decide what kind of paper you’re writing

When you’re assigned an essay, there are several different types you may get. Argumentative essays are designed to get the reader to agree with you on a topic. Informative or expository essays present information to the reader. Analytical essays offer up a point and then expand on it by analyzing relevant information. Thesis statements can look and sound different based on the type of paper you’re writing. For example:

  • Argumentative: The United States needs a viable third political party to decrease bipartisanship, increase options, and help reduce corruption in government.
  • Informative: The Libertarian party has thrown off elections before by gaining enough support in states to get on the ballot and by taking away crucial votes from candidates.
  • Analytical: An analysis of past presidential elections shows that while third party votes may have been the minority, they did affect the outcome of the elections in 2020, 2016, and beyond.

Step 2: Figure out what point you want to make

Once you know what type of paper you’re writing, you then need to figure out the point you want to make with your thesis statement, and subsequently, your paper. In other words, you need to decide to answer a question about something, such as:

  • What impact did reality TV have on American society?
  • How has the musical Hamilton affected perception of American history?
  • Why do I want to major in [chosen major here]?

If you have an argumentative essay, then you will be writing about an opinion. To make it easier, you may want to choose an opinion that you feel passionate about so that you’re writing about something that interests you. For example, if you have an interest in preserving the environment, you may want to choose a topic that relates to that. 

If you’re writing your college essay and they ask why you want to attend that school, you may want to have a main point and back it up with information, something along the lines of:

“Attending Harvard University would benefit me both academically and professionally, as it would give me a strong knowledge base upon which to build my career, develop my network, and hopefully give me an advantage in my chosen field.”

Step 3: Determine what information you’ll use to back up your point

Once you have the point you want to make, you need to figure out how you plan to back it up throughout the rest of your essay. Without this information, it will be hard to either prove or argue the main point of your thesis statement. If you decide to write about the Hamilton example, you may decide to address any falsehoods that the writer put into the musical, such as:

“The musical Hamilton, while accurate in many ways, leaves out key parts of American history, presents a nationalist view of founding fathers, and downplays the racism of the times.”

Once you’ve written your initial working thesis statement, you’ll then need to get information to back that up. For example, the musical completely leaves out Benjamin Franklin, portrays the founding fathers in a nationalist way that is too complimentary, and shows Hamilton as a staunch abolitionist despite the fact that his family likely did own slaves. 

Step 4: Revise and refine your thesis statement before you start writing

Read through your thesis statement several times before you begin to compose your full essay. You need to make sure the statement is ironclad, since it is the foundation of the entire paper. Edit it or have a peer review it for you to make sure everything makes sense and that you feel like you can truly write a paper on the topic. Once you’ve done that, you can then begin writing your paper.

When writing a thesis statement, there are some common pitfalls you should avoid so that your paper can be as solid as possible. Make sure you always edit the thesis statement before you do anything else. You also want to ensure that the thesis statement is clear and concise. Don’t make your reader hunt for your point. Finally, put your thesis statement at the end of the first paragraph and have your introduction flow toward that statement. Your reader will expect to find your statement in its traditional spot.

If you’re having trouble getting started, or need some guidance on your essay, there are tools available that can help you. CollegeVine offers a free peer essay review tool where one of your peers can read through your essay and provide you with valuable feedback. Getting essay feedback from a peer can help you wow your instructor or college admissions officer with an impactful essay that effectively illustrates your point.

A thesis is a type of research paper based on your original research. It is usually submitted as the final step of a master’s program or a capstone to a bachelor’s degree.

Writing a thesis can be a daunting experience. Other than a dissertation , it is one of the longest pieces of writing students typically complete. It relies on your ability to conduct research from start to finish: choosing a relevant topic , crafting a proposal , designing your research , collecting data , developing a robust analysis, drawing strong conclusions , and writing concisely .

You may have heard the word thesis as a standalone term or as a component of academic writing called a thesis statement . Keep in mind that these are two very different things.

  • A thesis statement is a very common component of an essay, particularly in the humanities. It usually comprises 1 or 2 sentences in the introduction of your essay , and should clearly and concisely summarize the central points of your academic essay .
  • A thesis is a long-form piece of academic writing, often taking more than a full semester to complete. It is generally a degree requirement for Master’s programs, and is also sometimes required to complete a bachelor’s degree in liberal arts colleges.
  • In the US, a dissertation is generally written as a final step toward obtaining a PhD.
  • In other countries (particularly the UK), a dissertation is generally written at the bachelor’s or master’s level.

The final structure of your thesis depends on a variety of components, such as:

  • Your discipline
  • Your theoretical approach

Humanities theses are often structured more like a longer-form essay . Just like in an essay, you build an argument to support a central thesis.

In both hard and social sciences, theses typically include an introduction , literature review , methodology section ,  results section , discussion section , and conclusion section . These are each presented in their own dedicated section or chapter. In some cases, you might want to add an appendix .

Thesis examples

We’ve compiled a short list of thesis examples to help you get started.

  • Example thesis #1:   “Abolition, Africans, and Abstraction: the Influence of the ‘Noble Savage’ on British and French Antislavery Thought, 1787-1807” by Suchait Kahlon.
  • Example thesis #2: “’A Starving Man Helping Another Starving Man’: UNRRA, India, and the Genesis of Global Relief, 1943-1947″ by Julian Saint Reiman.

The very first page of your thesis contains all necessary identifying information, including:

  • Your full title
  • Your full name
  • Your department
  • Your institution and degree program
  • Your submission date.

Sometimes the title page also includes your student ID, the name of your supervisor, or the university’s logo. Check out your university’s guidelines if you’re not sure.

Read more about title pages

The acknowledgements section is usually optional. Its main point is to allow you to thank everyone who helped you in your thesis journey, such as supervisors, friends, or family. You can also choose to write a preface , but it’s typically one or the other, not both.

Prevent plagiarism. Run a free check.

An abstract is a short summary of your thesis. Usually a maximum of 300 words long, it’s should include brief descriptions of your research objectives , methods, results, and conclusions. Though it may seem short, it introduces your work to your audience, serving as a first impression of your thesis.

A table of contents lists all of your sections, plus their corresponding page numbers and subheadings if you have them. This helps your reader seamlessly navigate your document.

Your table of contents should include all the major parts of your thesis. In particular, don’t forget the the appendices. If you used heading styles, it’s easy to generate an automatic table Microsoft Word.

If you have used a lot of industry- or field-specific abbreviations in your thesis, you should include them in an alphabetized list of abbreviations . This way, your readers can easily look up any meanings they aren’t familiar with.

Relatedly, if you find yourself using a lot of very specialized or field-specific terms that may not be familiar to your reader, consider including a glossary . Alphabetize the terms you want to include with a brief definition.

An introduction sets up the topic, purpose, and relevance of your thesis, as well as expectations for your reader. This should:

  • Ground your research topic , sharing any background information your reader may need
  • Define the scope of your work
  • Introduce any existing research on your topic, situating your work within a broader problem or debate
  • State your research question(s)
  • Outline (briefly) how the remainder of your work will proceed

In other words, your introduction should clearly and concisely show your reader the “what, why, and how” of your research.

Read more about introductions

A literature review helps you gain a robust understanding of any extant academic work on your topic, encompassing:

  • Selecting relevant sources
  • Determining the credibility of your sources
  • Critically evaluating each of your sources
  • Drawing connections between sources, including any themes, patterns, conflicts, or gaps

A literature review is not merely a summary of existing work. Rather, your literature review should ultimately lead to a clear justification for your own research, perhaps via:

  • Addressing a gap in the literature
  • Building on existing knowledge to draw new conclusions
  • Exploring a new theoretical or methodological approach
  • Introducing a new solution to an unresolved problem
  • Definitively advocating for one side of a theoretical debate

Theoretical framework

Your literature review can often form the basis for your theoretical framework, but these are not the same thing. A theoretical framework defines and analyzes the concepts and theories that your research hinges on.

Read more about theoretical frameworks

Your methodology chapter shows your reader how you conducted your research. It should be written clearly and methodically, easily allowing your reader to critically assess the credibility of your argument. Furthermore, your methods section should convince your reader that your method was the best way to answer your research question.

A methodology section should generally include:

  • Your overall approach ( quantitative vs. qualitative )
  • Your research methods (e.g., a longitudinal study )
  • Your data collection methods (e.g., interviews or a controlled experiment
  • Any tools or materials you used (e.g., computer software)
  • The data analysis methods you chose (e.g., statistical analysis , discourse analysis )
  • A strong, but not defensive justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. These two sections work in tandem, but shouldn’t repeat each other. While your results section can include hypotheses or themes, don’t include any speculation or new arguments here.

Your results section should:

  • State each (relevant) result with any (relevant) descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
  • Explain how each result relates to the research question
  • Determine whether the hypothesis was supported

Additional data (like raw numbers or interview transcripts ) can be included as an appendix . You can include tables and figures, but only if they help the reader better understand your results.

Read more about results sections

Your discussion section is where you can interpret your results in detail. Did they meet your expectations? How well do they fit within the framework that you built? You can refer back to any relevant source material to situate your results within your field, but leave most of that analysis in your literature review.

For any unexpected results, offer explanations or alternative interpretations of your data.

Read more about discussion sections

Your thesis conclusion should concisely answer your main research question. It should leave your reader with an ultra-clear understanding of your central argument, and emphasize what your research specifically has contributed to your field.

Why does your research matter? What recommendations for future research do you have? Lastly, wrap up your work with any concluding remarks.

Read more about conclusions

In order to avoid plagiarism , don’t forget to include a full reference list at the end of your thesis, citing the sources that you used. Choose one citation style and follow it consistently throughout your thesis, taking note of the formatting requirements of each style.

Which style you choose is often set by your department or your field, but common styles include MLA , Chicago , and APA.

Create APA citations Create MLA citations

In order to stay clear and concise, your thesis should include the most essential information needed to answer your research question. However, chances are you have many contributing documents, like interview transcripts or survey questions . These can be added as appendices , to save space in the main body.

Read more about appendices

Once you’re done writing, the next part of your editing process begins. Leave plenty of time for proofreading and editing prior to submission. Nothing looks worse than grammar mistakes or sloppy spelling errors!

Consider using a professional thesis editing service or grammar checker to make sure your final project is perfect.

Once you’ve submitted your final product, it’s common practice to have a thesis defense, an oral component of your finished work. This is scheduled by your advisor or committee, and usually entails a presentation and Q&A session.

After your defense , your committee will meet to determine if you deserve any departmental honors or accolades. However, keep in mind that defenses are usually just a formality. If there are any serious issues with your work, these should be resolved with your advisor way before a defense.

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

  • Your anticipated title
  • Your abstract
  • Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

  • Plan to attend graduate school soon
  • Have a particular topic you’d like to study more in-depth
  • Are considering a career in research
  • Would like a capstone experience to tie up your academic experience

Developing Strong Thesis Statements

Welcome to the Purdue OWL

The thesis statement or main claim must be debatable

An argumentative or persuasive piece of writing must begin with a debatable thesis or claim. In other words, the thesis must be something that people could reasonably have differing opinions on. If your thesis is something that is generally agreed upon or accepted as fact then there is no reason to try to persuade people.

Example of a non-debatable thesis statement:

This thesis statement is not debatable. First, the word pollution implies that something is bad or negative in some way. Furthermore, all studies agree that pollution is a problem; they simply disagree on the impact it will have or the scope of the problem. No one could reasonably argue that pollution is unambiguously good.

Example of a debatable thesis statement:

This is an example of a debatable thesis because reasonable people could disagree with it. Some people might think that this is how we should spend the nation's money. Others might feel that we should be spending more money on education. Still others could argue that corporations, not the government, should be paying to limit pollution.

Another example of a debatable thesis statement:

In this example there is also room for disagreement between rational individuals. Some citizens might think focusing on recycling programs rather than private automobiles is the most effective strategy.

The thesis needs to be narrow

Although the scope of your paper might seem overwhelming at the start, generally the narrower the thesis the more effective your argument will be. Your thesis or claim must be supported by evidence. The broader your claim is, the more evidence you will need to convince readers that your position is right.

Example of a thesis that is too broad:

There are several reasons this statement is too broad to argue. First, what is included in the category "drugs"? Is the author talking about illegal drug use, recreational drug use (which might include alcohol and cigarettes), or all uses of medication in general? Second, in what ways are drugs detrimental? Is drug use causing deaths (and is the author equating deaths from overdoses and deaths from drug related violence)? Is drug use changing the moral climate or causing the economy to decline? Finally, what does the author mean by "society"? Is the author referring only to America or to the global population? Does the author make any distinction between the effects on children and adults? There are just too many questions that the claim leaves open. The author could not cover all of the topics listed above, yet the generality of the claim leaves all of these possibilities open to debate.

Example of a narrow or focused thesis:

In this example the topic of drugs has been narrowed down to illegal drugs and the detriment has been narrowed down to gang violence. This is a much more manageable topic.

We could narrow each debatable thesis from the previous examples in the following way:

Narrowed debatable thesis 1:

This thesis narrows the scope of the argument by specifying not just the amount of money used but also how the money could actually help to control pollution.

Narrowed debatable thesis 2:

This thesis narrows the scope of the argument by specifying not just what the focus of a national anti-pollution campaign should be but also why this is the appropriate focus.

Qualifiers such as " typically ," " generally ," " usually ," or " on average " also help to limit the scope of your claim by allowing for the almost inevitable exception to the rule.

Types of claims

Claims typically fall into one of four categories. Thinking about how you want to approach your topic, or, in other words, what type of claim you want to make, is one way to focus your thesis on one particular aspect of your broader topic.

Claims of fact or definition: These claims argue about what the definition of something is or whether something is a settled fact. Example:

Claims of cause and effect: These claims argue that one person, thing, or event caused another thing or event to occur. Example:

Claims about value: These are claims made of what something is worth, whether we value it or not, how we would rate or categorize something. Example:

Claims about solutions or policies: These are claims that argue for or against a certain solution or policy approach to a problem. Example:

Which type of claim is right for your argument? Which type of thesis or claim you use for your argument will depend on your position and knowledge of the topic, your audience, and the context of your paper. You might want to think about where you imagine your audience to be on this topic and pinpoint where you think the biggest difference in viewpoints might be. Even if you start with one type of claim you probably will be using several within the paper. Regardless of the type of claim you choose to utilize it is key to identify the controversy or debate you are addressing and to define your position early on in the paper.

While Sandel argues that pursuing perfection through genetic engineering would decrease our sense of humility, he claims that the sense of solidarity we would lose is also important.

This thesis summarizes several points in Sandel’s argument, but it does not make a claim about how we should understand his argument. A reader who read Sandel’s argument would not also need to read an essay based on this descriptive thesis.  

Broad thesis (arguable, but difficult to support with evidence) 

Michael Sandel’s arguments about genetic engineering do not take into consideration all the relevant issues.

This is an arguable claim because it would be possible to argue against it by saying that Michael Sandel’s arguments do take all of the relevant issues into consideration. But the claim is too broad. Because the thesis does not specify which “issues” it is focused on—or why it matters if they are considered—readers won’t know what the rest of the essay will argue, and the writer won’t know what to focus on. If there is a particular issue that Sandel does not address, then a more specific version of the thesis would include that issue—hand an explanation of why it is important.  

Arguable thesis with analytical claim 

While Sandel argues persuasively that our instinct to “remake” (54) ourselves into something ever more perfect is a problem, his belief that we can always draw a line between what is medically necessary and what makes us simply “better than well” (51) is less convincing.

This is an arguable analytical claim. To argue for this claim, the essay writer will need to show how evidence from the article itself points to this interpretation. It’s also a reasonable scope for a thesis because it can be supported with evidence available in the text and is neither too broad nor too narrow.  

Arguable thesis with normative claim 

Given Sandel’s argument against genetic enhancement, we should not allow parents to decide on using Human Growth Hormone for their children.

This thesis tells us what we should do about a particular issue discussed in Sandel’s article, but it does not tell us how we should understand Sandel’s argument.  

Questions to ask about your thesis 

  • Is the thesis truly arguable? Does it speak to a genuine dilemma in the source, or would most readers automatically agree with it?  
  • Is the thesis too obvious? Again, would most or all readers agree with it without needing to see your argument?  
  • Is the thesis complex enough to require a whole essay's worth of argument?  
  • Is the thesis supportable with evidence from the text rather than with generalizations or outside research?  
  • Would anyone want to read a paper in which this thesis was developed? That is, can you explain what this paper is adding to our understanding of a problem, question, or topic?

25 Thesis Statement Examples That Will Make Writing a Breeze

JBirdwellBranson

Understanding what makes a good thesis statement is one of the major keys to writing a great research paper or argumentative essay. The thesis statement is where you make a claim that will guide you through your entire paper. If you find yourself struggling to make sense of your paper or your topic, then it's likely due to a weak thesis statement.

Let's take a minute to first understand what makes a solid thesis statement, and what key components you need to write one of your own.

Perfecting Your Thesis Statement

A thesis statement always goes at the beginning of the paper. It will typically be in the first couple of paragraphs of the paper so that it can introduce the body paragraphs, which are the supporting evidence for your thesis statement.

Your thesis statement should clearly identify an argument. You need to have a statement that is not only easy to understand, but one that is debatable. What that means is that you can't just put any statement of fact and have it be your thesis. For example, everyone knows that puppies are cute . An ineffective thesis statement would be, "Puppies are adorable and everyone knows it." This isn't really something that's a debatable topic.

Something that would be more debatable would be, "A puppy's cuteness is derived from its floppy ears, small body, and playfulness." These are three things that can be debated on. Some people might think that the cutest thing about puppies is the fact that they follow you around or that they're really soft and fuzzy.

All cuteness aside, you want to make sure that your thesis statement is not only debatable, but that it also actually thoroughly answers the research question that was posed. You always want to make sure that your evidence is supporting a claim that you made (and not the other way around). This is why it's crucial to read and research about a topic first and come to a conclusion later. If you try to get your research to fit your thesis statement, then it may not work out as neatly as you think. As you learn more, you discover more (and the outcome may not be what you originally thought).

Additionally, your thesis statement shouldn't be too big or too grand. It'll be hard to cover everything in a thesis statement like, "The federal government should act now on climate change." The topic is just too large to actually say something new and meaningful. Instead, a more effective thesis statement might be, "Local governments can combat climate change by providing citizens with larger recycling bins and offering local classes about composting and conservation." This is easier to work with because it's a smaller idea, but you can also discuss the overall topic that you might be interested in, which is climate change.

So, now that we know what makes a good, solid thesis statement, you can start to write your own. If you find that you're getting stuck or you are the type of person who needs to look at examples before you start something, then check out our list of thesis statement examples below.

Thesis statement examples

A quick note that these thesis statements have not been fully researched. These are merely examples to show you what a thesis statement might look like and how you can implement your own ideas into one that you think of independently. As such, you should not use these thesis statements for your own research paper purposes. They are meant to be used as examples only.

  • Vaccinations Because many children are unable to vaccinate due to illness, we must require that all healthy and able children be vaccinated in order to have herd immunity.
  • Educational Resources for Low-Income Students Schools should provide educational resources for low-income students during the summers so that they don't forget what they've learned throughout the school year.
  • School Uniforms School uniforms may be an upfront cost for families, but they eradicate the visual differences in income between students and provide a more egalitarian atmosphere at school.
  • Populism The rise in populism on the 2016 political stage was in reaction to increasing globalization, the decline of manufacturing jobs, and the Syrian refugee crisis.
  • Public Libraries Libraries are essential resources for communities and should be funded more heavily by local municipalities.
  • Cyber Bullying With more and more teens using smartphones and social media, cyber bullying is on the rise. Cyber bullying puts a lot of stress on many teens, and can cause depression, anxiety, and even suicidal thoughts. Parents should limit the usage of smart phones, monitor their children's online activity, and report any cyber bullying to school officials in order to combat this problem.
  • Medical Marijuana for Veterans Studies have shown that the use of medicinal marijuana has been helpful to veterans who suffer from Post-Traumatic Stress Disorder (PTSD). Medicinal marijuana prescriptions should be legal in all states and provided to these veterans. Additional medical or therapy services should also be researched and implemented in order to help them re-integrate back into civilian life.
  • Work-Life Balance Corporations should provide more work from home opportunities and six-hour workdays so that office workers have a better work-life balance and are more likely to be productive when they are in the office.
  • Teaching Youths about Consensual Sex Although sex education that includes a discussion of consensual sex would likely lead to less sexual assault, parents need to teach their children the meaning of consent from a young age with age appropriate lessons.
  • Whether or Not to Attend University A degree from a university provides invaluable lessons on life and a future career, but not every high school student should be encouraged to attend a university directly after graduation. Some students may benefit from a trade school or a "gap year" where they can think more intensely about what it is they want to do for a career and how they can accomplish this.
  • Studying Abroad Studying abroad is one of the most culturally valuable experiences you can have in college. It is the only way to get completely immersed in another language and learn how other cultures and countries are different from your own.
  • Women's Body Image Magazines have done a lot in the last five years to include a more diverse group of models, but there is still a long way to go to promote a healthy woman's body image collectively as a culture.
  • Cigarette Tax Heavily taxing and increasing the price of cigarettes is essentially a tax on the poorest Americans, and it doesn't deter them from purchasing. Instead, the state and federal governments should target those economically disenfranchised with early education about the dangers of smoking.
  • Veganism A vegan diet, while a healthy and ethical way to consume food, indicates a position of privilege. It also limits you to other cultural food experiences if you travel around the world.
  • University Athletes Should be Compensated University athletes should be compensated for their service to the university, as it is difficult for these students to procure and hold a job with busy academic and athletic schedules. Many student athletes on scholarship also come from low-income neighborhoods and it is a struggle to make ends meet when they are participating in athletics.
  • Women in the Workforce Sheryl Sandberg makes a lot of interesting points in her best-selling book, Lean In , but she only addressed the very privileged working woman and failed to speak to those in lower-skilled, lower-wage jobs.
  • Assisted Suicide Assisted suicide should be legal and doctors should have the ability to make sure their patients have the end-of-life care that they want to receive.
  • Celebrity and Political Activism Although Taylor Swift's lyrics are indicative of a feminist perspective, she should be more politically active and vocal to use her position of power for the betterment of society.
  • The Civil War The insistence from many Southerners that the South seceded from the Union for states' rights versus the fact that they seceded for the purposes of continuing slavery is a harmful myth that still affects race relations today.
  • Blue Collar Workers Coal miners and other blue-collar workers whose jobs are slowly disappearing from the workforce should be re-trained in jobs in the technology sector or in renewable energy. A program to re-train these workers would not only improve local economies where jobs have been displaced, but would also lead to lower unemployment nationally.
  • Diversity in the Workforce Having a diverse group of people in an office setting leads to richer ideas, more cooperation, and more empathy between people with different skin colors or backgrounds.
  • Re-Imagining the Nuclear Family The nuclear family was traditionally defined as one mother, one father, and 2.5 children. This outdated depiction of family life doesn't quite fit with modern society. The definition of normal family life shouldn't be limited to two-parent households.
  • Digital Literacy Skills With more information readily available than ever before, it's crucial that students are prepared to examine the material they're reading and determine whether or not it's a good source or if it has misleading information. Teaching students digital literacy and helping them to understand the difference between opinion or propaganda from legitimate, real information is integral.
  • Beauty Pageants Beauty pageants are presented with the angle that they empower women. However, putting women in a swimsuit on a stage while simultaneously judging them on how well they answer an impossible question in a short period of time is cruel and purely for the amusement of men. Therefore, we should stop televising beauty pageants.
  • Supporting More Women to Run for a Political Position In order to get more women into political positions, more women must run for office. There must be a grassroots effort to educate women on how to run for office, who among them should run, and support for a future candidate for getting started on a political career.

Still stuck? Need some help with your thesis statement?

If you are still uncertain about how to write a thesis statement or what a good thesis statement is, be sure to consult with your teacher or professor to make sure you're on the right track. It's always a good idea to check in and make sure that your thesis statement is making a solid argument and that it can be supported by your research.

After you're done writing, it's important to have someone take a second look at your paper so that you can ensure there are no mistakes or errors. It's difficult to spot your own mistakes, which is why it's always recommended to have someone help you with the revision process, whether that's a teacher, the writing center at school, or a professional editor such as one from ServiceScape .

Developing a Thesis Statement

Many papers you write require developing a thesis statement. In this section you’ll learn what a thesis statement is and how to write one.

Keep in mind that not all papers require thesis statements . If in doubt, please consult your instructor for assistance.

What is a thesis statement?

A thesis statement . . .

  • Makes an argumentative assertion about a topic; it states the conclusions that you have reached about your topic.
  • Makes a promise to the reader about the scope, purpose, and direction of your paper.
  • Is focused and specific enough to be “proven” within the boundaries of your paper.
  • Is generally located near the end of the introduction ; sometimes, in a long paper, the thesis will be expressed in several sentences or in an entire paragraph.
  • Identifies the relationships between the pieces of evidence that you are using to support your argument.

Not all papers require thesis statements! Ask your instructor if you’re in doubt whether you need one.

Identify a topic

Your topic is the subject about which you will write. Your assignment may suggest several ways of looking at a topic; or it may name a fairly general concept that you will explore or analyze in your paper.

Consider what your assignment asks you to do

Inform yourself about your topic, focus on one aspect of your topic, ask yourself whether your topic is worthy of your efforts, generate a topic from an assignment.

Below are some possible topics based on sample assignments.

Sample assignment 1

Analyze Spain’s neutrality in World War II.

Identified topic

Franco’s role in the diplomatic relationships between the Allies and the Axis

This topic avoids generalities such as “Spain” and “World War II,” addressing instead on Franco’s role (a specific aspect of “Spain”) and the diplomatic relations between the Allies and Axis (a specific aspect of World War II).

Sample assignment 2

Analyze one of Homer’s epic similes in the Iliad.

The relationship between the portrayal of warfare and the epic simile about Simoisius at 4.547-64.

This topic focuses on a single simile and relates it to a single aspect of the Iliad ( warfare being a major theme in that work).

Developing a Thesis Statement–Additional information

Your assignment may suggest several ways of looking at a topic, or it may name a fairly general concept that you will explore or analyze in your paper. You’ll want to read your assignment carefully, looking for key terms that you can use to focus your topic.

Sample assignment: Analyze Spain’s neutrality in World War II Key terms: analyze, Spain’s neutrality, World War II

After you’ve identified the key words in your topic, the next step is to read about them in several sources, or generate as much information as possible through an analysis of your topic. Obviously, the more material or knowledge you have, the more possibilities will be available for a strong argument. For the sample assignment above, you’ll want to look at books and articles on World War II in general, and Spain’s neutrality in particular.

As you consider your options, you must decide to focus on one aspect of your topic. This means that you cannot include everything you’ve learned about your topic, nor should you go off in several directions. If you end up covering too many different aspects of a topic, your paper will sprawl and be unconvincing in its argument, and it most likely will not fulfull the assignment requirements.

For the sample assignment above, both Spain’s neutrality and World War II are topics far too broad to explore in a paper. You may instead decide to focus on Franco’s role in the diplomatic relationships between the Allies and the Axis , which narrows down what aspects of Spain’s neutrality and World War II you want to discuss, as well as establishes a specific link between those two aspects.

Before you go too far, however, ask yourself whether your topic is worthy of your efforts. Try to avoid topics that already have too much written about them (i.e., “eating disorders and body image among adolescent women”) or that simply are not important (i.e. “why I like ice cream”). These topics may lead to a thesis that is either dry fact or a weird claim that cannot be supported. A good thesis falls somewhere between the two extremes. To arrive at this point, ask yourself what is new, interesting, contestable, or controversial about your topic.

As you work on your thesis, remember to keep the rest of your paper in mind at all times . Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Derive a main point from topic

Once you have a topic, you will have to decide what the main point of your paper will be. This point, the “controlling idea,” becomes the core of your argument (thesis statement) and it is the unifying idea to which you will relate all your sub-theses. You can then turn this “controlling idea” into a purpose statement about what you intend to do in your paper.

Look for patterns in your evidence

Compose a purpose statement.

Consult the examples below for suggestions on how to look for patterns in your evidence and construct a purpose statement.

  • Franco first tried to negotiate with the Axis
  • Franco turned to the Allies when he couldn’t get some concessions that he wanted from the Axis

Possible conclusion:

Spain’s neutrality in WWII occurred for an entirely personal reason: Franco’s desire to preserve his own (and Spain’s) power.

Purpose statement

This paper will analyze Franco’s diplomacy during World War II to see how it contributed to Spain’s neutrality.
  • The simile compares Simoisius to a tree, which is a peaceful, natural image.
  • The tree in the simile is chopped down to make wheels for a chariot, which is an object used in warfare.

At first, the simile seems to take the reader away from the world of warfare, but we end up back in that world by the end.

This paper will analyze the way the simile about Simoisius at 4.547-64 moves in and out of the world of warfare.

Derive purpose statement from topic

To find out what your “controlling idea” is, you have to examine and evaluate your evidence . As you consider your evidence, you may notice patterns emerging, data repeated in more than one source, or facts that favor one view more than another. These patterns or data may then lead you to some conclusions about your topic and suggest that you can successfully argue for one idea better than another.

For instance, you might find out that Franco first tried to negotiate with the Axis, but when he couldn’t get some concessions that he wanted from them, he turned to the Allies. As you read more about Franco’s decisions, you may conclude that Spain’s neutrality in WWII occurred for an entirely personal reason: his desire to preserve his own (and Spain’s) power. Based on this conclusion, you can then write a trial thesis statement to help you decide what material belongs in your paper.

Sometimes you won’t be able to find a focus or identify your “spin” or specific argument immediately. Like some writers, you might begin with a purpose statement just to get yourself going. A purpose statement is one or more sentences that announce your topic and indicate the structure of the paper but do not state the conclusions you have drawn . Thus, you might begin with something like this:

  • This paper will look at modern language to see if it reflects male dominance or female oppression.
  • I plan to analyze anger and derision in offensive language to see if they represent a challenge of society’s authority.

At some point, you can turn a purpose statement into a thesis statement. As you think and write about your topic, you can restrict, clarify, and refine your argument, crafting your thesis statement to reflect your thinking.

As you work on your thesis, remember to keep the rest of your paper in mind at all times. Sometimes your thesis needs to evolve as you develop new insights, find new evidence, or take a different approach to your topic.

Compose a draft thesis statement

If you are writing a paper that will have an argumentative thesis and are having trouble getting started, the techniques in the table below may help you develop a temporary or “working” thesis statement.

Begin with a purpose statement that you will later turn into a thesis statement.

Assignment: Discuss the history of the Reform Party and explain its influence on the 1990 presidential and Congressional election.

Purpose Statement: This paper briefly sketches the history of the grassroots, conservative, Perot-led Reform Party and analyzes how it influenced the economic and social ideologies of the two mainstream parties.

Question-to-Assertion

If your assignment asks a specific question(s), turn the question(s) into an assertion and give reasons why it is true or reasons for your opinion.

Assignment : What do Aylmer and Rappaccini have to be proud of? Why aren’t they satisfied with these things? How does pride, as demonstrated in “The Birthmark” and “Rappaccini’s Daughter,” lead to unexpected problems?

Beginning thesis statement: Alymer and Rappaccinni are proud of their great knowledge; however, they are also very greedy and are driven to use their knowledge to alter some aspect of nature as a test of their ability. Evil results when they try to “play God.”

Write a sentence that summarizes the main idea of the essay you plan to write.

Main idea: The reason some toys succeed in the market is that they appeal to the consumers’ sense of the ridiculous and their basic desire to laugh at themselves.

Make a list of the ideas that you want to include; consider the ideas and try to group them.

  • nature = peaceful
  • war matériel = violent (competes with 1?)
  • need for time and space to mourn the dead
  • war is inescapable (competes with 3?)

Use a formula to arrive at a working thesis statement (you will revise this later).

  • although most readers of _______ have argued that _______, closer examination shows that _______.
  • _______ uses _______ and _____ to prove that ________.
  • phenomenon x is a result of the combination of __________, __________, and _________.

What to keep in mind as you draft an initial thesis statement

Beginning statements obtained through the methods illustrated above can serve as a framework for planning or drafting your paper, but remember they’re not yet the specific, argumentative thesis you want for the final version of your paper. In fact, in its first stages, a thesis statement usually is ill-formed or rough and serves only as a planning tool.

As you write, you may discover evidence that does not fit your temporary or “working” thesis. Or you may reach deeper insights about your topic as you do more research, and you will find that your thesis statement has to be more complicated to match the evidence that you want to use.

You must be willing to reject or omit some evidence in order to keep your paper cohesive and your reader focused. Or you may have to revise your thesis to match the evidence and insights that you want to discuss. Read your draft carefully, noting the conclusions you have drawn and the major ideas which support or prove those conclusions. These will be the elements of your final thesis statement.

Sometimes you will not be able to identify these elements in your early drafts, but as you consider how your argument is developing and how your evidence supports your main idea, ask yourself, “ What is the main point that I want to prove/discuss? ” and “ How will I convince the reader that this is true? ” When you can answer these questions, then you can begin to refine the thesis statement.

Refine and polish the thesis statement

To get to your final thesis, you’ll need to refine your draft thesis so that it’s specific and arguable.

  • Ask if your draft thesis addresses the assignment
  • Question each part of your draft thesis
  • Clarify vague phrases and assertions
  • Investigate alternatives to your draft thesis

Consult the example below for suggestions on how to refine your draft thesis statement.

Sample Assignment

Choose an activity and define it as a symbol of American culture. Your essay should cause the reader to think critically about the society which produces and enjoys that activity.

  • Ask The phenomenon of drive-in facilities is an interesting symbol of american culture, and these facilities demonstrate significant characteristics of our society.This statement does not fulfill the assignment because it does not require the reader to think critically about society.
Drive-ins are an interesting symbol of American culture because they represent Americans’ significant creativity and business ingenuity.
Among the types of drive-in facilities familiar during the twentieth century, drive-in movie theaters best represent American creativity, not merely because they were the forerunner of later drive-ins and drive-throughs, but because of their impact on our culture: they changed our relationship to the automobile, changed the way people experienced movies, and changed movie-going into a family activity.
While drive-in facilities such as those at fast-food establishments, banks, pharmacies, and dry cleaners symbolize America’s economic ingenuity, they also have affected our personal standards.
While drive-in facilities such as those at fast- food restaurants, banks, pharmacies, and dry cleaners symbolize (1) Americans’ business ingenuity, they also have contributed (2) to an increasing homogenization of our culture, (3) a willingness to depersonalize relationships with others, and (4) a tendency to sacrifice quality for convenience.

This statement is now specific and fulfills all parts of the assignment. This version, like any good thesis, is not self-evident; its points, 1-4, will have to be proven with evidence in the body of the paper. The numbers in this statement indicate the order in which the points will be presented. Depending on the length of the paper, there could be one paragraph for each numbered item or there could be blocks of paragraph for even pages for each one.

Complete the final thesis statement

The bottom line.

As you move through the process of crafting a thesis, you’ll need to remember four things:

  • Context matters! Think about your course materials and lectures. Try to relate your thesis to the ideas your instructor is discussing.
  • As you go through the process described in this section, always keep your assignment in mind . You will be more successful when your thesis (and paper) responds to the assignment than if it argues a semi-related idea.
  • Your thesis statement should be precise, focused, and contestable ; it should predict the sub-theses or blocks of information that you will use to prove your argument.
  • Make sure that you keep the rest of your paper in mind at all times. Change your thesis as your paper evolves, because you do not want your thesis to promise more than your paper actually delivers.

In the beginning, the thesis statement was a tool to help you sharpen your focus, limit material and establish the paper’s purpose. When your paper is finished, however, the thesis statement becomes a tool for your reader. It tells the reader what you have learned about your topic and what evidence led you to your conclusion. It keeps the reader on track–well able to understand and appreciate your argument.

How to Write a Strong Thesis Statement

A thesis can be found in many places—a debate speech, a lawyer’s closing argument, even an advertisement. But the most common place for a thesis statement (and probably why you’re reading this article) is in an essay.

Whether you’re writing an argumentative paper, an informative essay, or a compare/contrast statement, you need a thesis. Without a thesis, your argument falls flat and your information is unfocused. Since a thesis is so important, it’s probably a good idea to look at some tips on how to put together a strong one.

Guide Overview

What is a “thesis statement” anyway.

  • 2 categories of thesis statements: informative and persuasive
  • 2 styles of thesis statements
  • Formula for a strong argumentative thesis
  • The qualities of a solid thesis statement (video)

You may have heard of something called a “thesis.” It’s what seniors commonly refer to as their final paper before graduation. That’s not what we’re talking about here. That type of thesis is a long, well-written paper that takes years to piece together.

Instead, we’re talking about a single sentence that ties together the main idea of any argument . In the context of student essays, it’s a statement that summarizes your topic and declares your position on it. This sentence can tell a reader whether your essay is something they want to read.

2 Categories of Thesis Statements: Informative and Persuasive

Just as there are different types of essays, there are different types of thesis statements. The thesis should match the essay.

For example, with an informative essay, you should compose an informative thesis (rather than argumentative). You want to declare your intentions in this essay and guide the reader to the conclusion that you reach.

To make a peanut butter and jelly sandwich, you must procure the ingredients, find a knife, and spread the condiments.

This thesis showed the reader the topic (a type of sandwich) and the direction the essay will take (describing how the sandwich is made).

Most other types of essays, whether compare/contrast, argumentative, or narrative, have thesis statements that take a position and argue it. In other words, unless your purpose is simply to inform, your thesis is considered persuasive. A persuasive thesis usually contains an opinion and the reason why your opinion is true.

Peanut butter and jelly sandwiches are the best type of sandwich because they are versatile, easy to make, and taste good.

In this persuasive thesis statement, you see that I state my opinion (the best type of sandwich), which means I have chosen a stance. Next, I explain that my opinion is correct with several key reasons. This persuasive type of thesis can be used in any essay that contains the writer’s opinion, including, as I mentioned above, compare/contrast essays, narrative essays, and so on.

2 Styles of Thesis Statements

Just as there are two different types of thesis statements (informative and persuasive), there are two basic styles you can use.

The first style uses a list of two or more points . This style of thesis is perfect for a brief essay that contains only two or three body paragraphs. This basic five-paragraph essay is typical of middle and high school assignments.

C.S. Lewis’s Chronicles of Narnia series is one of the richest works of the 20th century because it offers an escape from reality, teaches readers to have faith even when they don’t understand, and contains a host of vibrant characters.

In the above persuasive thesis, you can see my opinion about Narnia followed by three clear reasons. This thesis is perfect for setting up a tidy five-paragraph essay.

In college, five paragraph essays become few and far between as essay length gets longer. Can you imagine having only five paragraphs in a six-page paper? For a longer essay, you need a thesis statement that is more versatile. Instead of listing two or three distinct points, a thesis can list one overarching point that all body paragraphs tie into.

Good vs. evil is the main theme of Lewis’s Narnia series, as is made clear through the struggles the main characters face in each book.

In this thesis, I have made a claim about the theme in Narnia followed by my reasoning. The broader scope of this thesis allows me to write about each of the series’ seven novels. I am no longer limited in how many body paragraphs I can logically use.

Formula for a Strong Argumentative Thesis

One thing I find that is helpful for students is having a clear template. While students rarely end up with a thesis that follows this exact wording, the following template creates a good starting point:

___________ is true because of ___________, ___________, and ___________.

Conversely, the formula for a thesis with only one point might follow this template:

___________________ is true because of _____________________.

Students usually end up using different terminology than simply “because,” but having a template is always helpful to get the creative juices flowing.

The Qualities of a Solid Thesis Statement

When composing a thesis, you must consider not only the format, but other qualities like length, position in the essay, and how strong the argument is.

Length: A thesis statement can be short or long, depending on how many points it mentions. Typically, however, it is only one concise sentence. It does contain at least two clauses, usually an independent clause (the opinion) and a dependent clause (the reasons). You probably should aim for a single sentence that is at least two lines, or about 30 to 40 words long.

Position: A thesis statement always belongs at the beginning of an essay. This is because it is a sentence that tells the reader what the writer is going to discuss. Teachers will have different preferences for the precise location of the thesis, but a good rule of thumb is in the introduction paragraph, within the last two or three sentences.

Strength: Finally, for a persuasive thesis to be strong, it needs to be arguable. This means that the statement is not obvious, and it is not something that everyone agrees is true.

Example of weak thesis:

Peanut butter and jelly sandwiches are easy to make because it just takes three ingredients.

Most people would agree that PB&J is one of the easiest sandwiches in the American lunch repertoire.

Example of a stronger thesis:

Peanut butter and jelly sandwiches are fun to eat because they always slide around.

This is more arguable because there are plenty of folks who might think a PB&J is messy or slimy rather than fun.

Composing a thesis statement does take a bit more thought than many other parts of an essay. However, because a thesis statement can contain an entire argument in just a few words, it is worth taking the extra time to compose this sentence. It can direct your research and your argument so that your essay is tight, focused, and makes readers think.

How to Write a Solid Thesis Statement

The important sentence expresses your central assertion or argument

A thesis statement provides the foundation for your entire research paper or essay. This statement is the central assertion that you want to express in your essay. A successful thesis statement is one that is made up of one or two sentences clearly laying out your central idea and expressing an informed, reasoned answer to your research question.

Usually, the thesis statement will appear at the end of the first paragraph of your paper. There are a few different types, and the content of your thesis statement will depend upon the type of paper you’re writing.

Key Takeaways: Writing a Thesis Statement

  • A thesis statement gives your reader a preview of your paper's content by laying out your central idea and expressing an informed, reasoned answer to your research question.
  • Thesis statements will vary depending on the type of paper you are writing, such as an expository essay, argument paper, or analytical essay.
  • Before creating a thesis statement, determine whether you are defending a stance, giving an overview of an event, object, or process, or analyzing your subject

Expository Essay Thesis Statement Examples

An expository essay "exposes" the reader to a new topic; it informs the reader with details, descriptions, or explanations of a subject. If you are writing an expository essay , your thesis statement should explain to the reader what she will learn in your essay. For example:

  • The United States spends more money on its military budget than all the industrialized nations combined.
  • Gun-related homicides and suicides are increasing after years of decline.
  • Hate crimes have increased three years in a row, according to the FBI.
  • Post-traumatic stress disorder (PTSD) increases the risk of stroke and arterial fibrillation (irregular heartbeat).

These statements provide a statement of fact about the topic (not just opinion) but leave the door open for you to elaborate with plenty of details. In an expository essay, you don't need to develop an argument or prove anything; you only need to understand your topic and present it in a logical manner. A good thesis statement in an expository essay always leaves the reader wanting more details.

Types of Thesis Statements

Before creating a thesis statement, it's important to ask a few basic questions, which will help you determine the kind of essay or paper you plan to create:

  • Are you defending a stance in a controversial essay ?
  • Are you simply giving an overview or describing an event, object, or process?
  • Are you conducting an analysis of an event, object, or process?

In every thesis statement , you will give the reader a preview of your paper's content, but the message will differ a little depending on the essay type .

Argument Thesis Statement Examples

If you have been instructed to take a stance on one side of a controversial issue, you will need to write an argument essay . Your thesis statement should express the stance you are taking and may give the reader a preview or a hint of your evidence. The thesis of an argument essay could look something like the following:

  • Self-driving cars are too dangerous and should be banned from the roadways.
  • The exploration of outer space is a waste of money; instead, funds should go toward solving issues on Earth, such as poverty, hunger, global warming, and traffic congestion.
  • The U.S. must crack down on illegal immigration.
  • Street cameras and street-view maps have led to a total loss of privacy in the United States and elsewhere.

These thesis statements are effective because they offer opinions that can be supported by evidence. If you are writing an argument essay, you can craft your own thesis around the structure of the statements above.

Analytical Essay Thesis Statement Examples

In an analytical essay assignment, you will be expected to break down a topic, process, or object in order to observe and analyze your subject piece by piece. Examples of a thesis statement for an analytical essay include:

  • The criminal justice reform bill passed by the U.S. Senate in late 2018 (" The First Step Act ") aims to reduce prison sentences that disproportionately fall on nonwhite criminal defendants.
  • The rise in populism and nationalism in the U.S. and European democracies has coincided with the decline of moderate and centrist parties that have dominated since WWII.
  • Later-start school days increase student success for a variety of reasons.

Because the role of the thesis statement is to state the central message of your entire paper, it is important to revisit (and maybe rewrite) your thesis statement after the paper is written. In fact, it is quite normal for your message to change as you construct your paper.

The main idea. The argument of an essay. The thesis. It’s a tricky thing to define “thesis” because theses come in all sorts of shapes and sizes. A thesis can be a sentence, two sentences, perhaps even an entire paragraph. Every thesis, though, regardless of where in an essay it appears, does a few important things:

  • A thesis acts as a unifying idea for every piece of evidence in an essay.
  • A thesis results from research in addition to the writer’s own beliefs or opinions.
  • A thesis answers a specific question.

There are lots of ways to create a successful thesis because good theses come in all sorts of varieties. What all successful argumentative theses have in common, though, are the following characteristics:

  • A good thesis statement is arguable. In other words, the writer’s claim might be challenged or opposed.
  • A good thesis statement expresses one main idea, and that idea controls what is said, what is left out, and how the delivered evidence is organized.
  • A good thesis statement is specific and insightful.
  • A good thesis statement encourages discussion.
  • A good thesis statement is supported by relevant evidence. Every paragraph should contribute to proving the thesis to be valid

Developing a Thesis

  • Define the Rhetorical Situation: The key to developing an appropriate thesis is to begin by examining the rhetorical situation: What is the purpose of your essay (e.g., to inform, to persuade, to analyze)? To whom are you writing (e.g., classmates, members of a particular interest or age group)?
  • Choose a Topic: Based on the purpose of and audience for your essay, what is an appropriate topic? Moreover, what is an appropriate topic that also interests you personally?
  • Start with What You Know: What do you know about your topic? What have you heard on the news about your topic? Do you have personal experiences related to your topic? If so, what are they?
  • Research What You Don’t Know: Start by searching the library databases (e.g., with Academic Search Premier or WorldCat). It’s best to begin by searching with your general topic and then refining your initial results. Gather a variety of sources and start reading. Some general reading on your topic will help you with the next step.
  • Take a Position: Before you take a position, be sure you have done ample reading and you are aware of the various positions regarding your topic. Most issues have more nuances than basic understandings suggest. It is not enough to be “for” or “against” an issue. You must be able to support your position with evidence and logical reasoning, and research can help you in this regard.

Refining Your Thesis

After choosing a position, in forming reasoning for your decision, you must be clear and specific. You must be able to substantiate your claim using authoritative, credible, and relevant source material. Theses tend, in draft form, to begin as general and to become more specific as you do more research. Let’s look at how we might turn a weak thesis into a strong thesis.

Weak thesis:

On April 20, 2010, the explosion of the Deepwater Horizon oil platform caused the largest man-made disaster in U.S. history.

This thesis has a serious problem for two reasons: it doesn’t actually make an argument. It simply states an unproven fact: that the Deepwater Horizon oil spill is the largest man-made disaster in U.S. history. In order to be successful, a thesis must be arguable and supported by evidence. If we consider that a thesis must be a statement that reasonable people may disagree with and a position substantiated with credible evidence, this thesis is problematic because no one will disagree with the date the oil spill occurred and because the claim that the oil spill was the largest man-made disaster in U.S. history is unsubstantiated.

A still weak thesis:

Many people are to blame for the oil spill that resulted from the explosion of the Deepwater Horizon oil platform, which caused the largest man-made environmental disaster in U.S. history.

This thesis is better than the first because it does more than state a fact, but it is still problematic: it is not specific enough, and the claim that the Deepwater Horizon oil spill is the “largest man-made” disaster is still unsubstantiated. This thesis might, instead, attempt to answer the following questions: “Who is to blame for the Deepwater Horizon oil spill?” and “Why might it be considered the largest man-made environmental disaster in the U.S. history?” A successful thesis must be arguable and must answer a specific question.

A better thesis:

BP, President George W. Bush, President Barack Obama, Republicans in Congress, Democrats in Congress, and every citizen in the United States share the blame for the oil spill that resulted from the explosion of the Deepwater Horizon oil platform, which some consider the largest man-made environmental disaster in U.S. history, and in order to prevent another such disaster, Congress must develop better regulations, oil companies must enact better maintenance procedures, and Americans must decrease their dependence on oil.

This thesis is certainly more specific, but it’s trying to do too much. Proving that all parties mentioned are to blame for the Deepwater Horizon oil spill and that the solutions mentioned will prevent another oil disaster requires covering a lot of ground. A good thesis is arguable and specific, but also has one main idea. This thesis has too many main ideas.

An even better thesis:

Oil companies and the federal government share responsibility for the Gulf oil spill that resulted from the April 2010 Deepwater Horizon explosion.

This thesis works better than the previous versions because it’s arguable, specific, and focused on one main idea, but not so specific as to greatly limit discussion of the topic. From an essay based on such a thesis, readers will expect evidence that supports the claim that oil companies and the federal government hold joint responsibility for the Gulf oil spill.

The Thesis Sentence

The thesis sentence is arguably the most important sentence in an academic paper. Without a good, clear thesis that presents an intriguing arguable point, a paper risks becoming unfocused, aimless, not worth the reader's time.

The Challenge of the Thesis Sentence

Because the thesis sentence is the most important sentence of a paper, it is also the most difficult to write. Readers expect a great deal of a thesis sentence: they want it to powerfully and clearly indicate what the writer is going to say, why she is going to say it, and even how it is that she is going to go about getting it said. In other words, the job of the thesis sentence is to organize, predict, control, and define the paper's argument.

In many cases, a thesis sentence will not only present the paper's argument, it will also point to and direct the course that the argument is going to take. In other words, it may also include an "essay map" - i.e., phrases or clauses that map out for the reader (and the writer) the argument that is to come. In some cases, then, the thesis sentence not only promises an argument, it promises the structure of that argument as well.

The promises that a thesis sentence makes to a reader are important ones and must be kept. It's helpful sometimes to explain the thesis as a kind of contract between reader and writer: if this contract is broken, the reader will feel frustrated and betrayed. Accordingly, the writer must be very careful in the development of the thesis.

Working on the Thesis Sentence

Chances are if you've had trouble following or deciphering the argument of a paper, there's a problem with the thesis. If a tutor's first response to a paper is that he doesn't know what the paper is about, then the thesis sentence is either absent from the paper, or it's hiding. The first thing you might wish to do is to ask the writer what his thesis is. He may point to a particular sentence that he thinks is his thesis, giving you a very good place to start.

Let's say that you've read a paper in which you've encountered this thesis:

Although heterosexuality has long been regarded as the only natural expression of sexuality, this view has been recently and strongly challenged by the gay rights movement.

What's wrong with this sentence? Many things, the most troublesome of which is that it argues nothing. Who is going to deny that the heteronormative view has been challenged by the gay rights movement? At this point, you need to ask the writer some questions. In what specific ways has the gay rights movement challenged heterosexuality? Do these ways seem reasonable to the writer? Why or why not? What argument does he intend to make about this topic? Why does he want to make it? To whom does he want to make it?

After giving the writer some time to think about and talk about these questions, you'll probably want to bring up another problem that is certain to arise out of a thesis like this one: the matter of structure. Any paper that follows a thesis like this one is likely to ramble. How can the reader figure out what all the supporting paragraphs are doing when the argument itself is so ill-defined? You'll want to show the writer that a strong thesis suggests - even helps to create - strong topic sentences. (More on this when we consider matters of structure, below).

But before we move on to other matters, let's consider the problem of this thesis from another angle: its style. We can see without difficulty that the sentence presents us with at least two stylistic problems: 1) this thesis, which should be the most powerful sentence of the paper, employs the passive voice, and 2) the introductory clause functions as a dangling modifier (who regards heterosexuality as the only natural way to express sexuality?).

Both stylistic problems point to something at work in the sentence: the writer obliterates the actors - heterosexuals and homosexuals alike - by using the dangling modifier and the passive voice. Why does he do that? Is he avoiding naming the actors in these sentences because he's not comfortable with the positions they take? Is he unable to declare himself because he feels paralyzed by the sense that he must write a paper that is politically correct? Or does he obliterate the actors with the passive voice because he himself wishes to remain passive on this topic?

These are questions to pose to the writer, though they must be posed gently. In fact, you might gently pose these questions via a discussion of style. For instance, you might also suggest that the writer rewrite the sentence in the active voice:

Although our society has long regarded heterosexuality as the only natural expression of sexuality, members of the gay rights movement have challenged this view strongly.

This active construction helps us to see clearly what's missing:

Although our society has long regarded heterosexuality as the only natural expression of sexuality, members of the gay rights movement have challenged this view strongly, arguing XYZ.

This more active construction also makes it clear that merely enumerating the points the author wants to make is not the same thing as creating an argument. The writer should now be able to see that he needs to go one step further - he needs to reveal his own position on the gay rights movement. The rest of the paper will develop this position.

In short, there are many ways to begin work on a writer's thesis sentences. Almost all of them will lead you to other matters important to the paper's success: its structure, its language, its style. Try to make any conversation you have about thesis sentences point to other problems with the writing. Not only is this strategy efficient, but it also encourages a writer to see how important a thesis is to the overall success of his essay.

Talking Your Way to a Workable Thesis

For the sake of making (we hope) a somewhat humorous illustration of the matter at hand, we offer the following scenario, which shows how tutor and tutee can talk their way to a workable thesis - and, indeed, to a good essay. So sit back, and enjoy this "break" in your training.

Imagine (though it is indeed quite a stretch) that a freshman composition teacher has the audacity to assign a paper on cats (the animals, not the play). The students may write any kind of paper they like - narration, description, compare/contrast, etc. - as long as their essays contain a thesis (that is, that they argue some point) concerning cats. A writer comes to you for help in developing her thesis. You read the assignment, and then you tell the writer that she first must choose the kind of paper she would like to do. She decides to do a narrative because she thinks she has more freedom in the narrative form. Then you ask her what she has to say about cats. "I don't like them," is her reply.

"OK," you say, "that's a start. Why don't you like them?" The writer has lots of reasons: they smell, they're aloof, they shed, they keep you up nights when they're in heat, they're very middle class, they steal food off of the table, they don't get along with dogs (the writer loves dogs), and on, and on. After brainstorming for a while, you tell the writer to choose a few points on which she'd like to focus - preferably those points that she feels strongly about or those which seem unusual. She picks three: cats smell, they steal food, and they are middle class. She offers her thesis: "I don't like cats because they are smelly, thieving, and middle class."

"O.K.," you say, "It's not a very sophisticated thesis but we can use it for now. After all, it defines your stance, it controls your subject, it organizes your argument, and it predicts your strategy - all the things that a thesis ought to do. Now let's consider how to develop the thesis, point by point."

You begin to ask questions about cats and their smell. "What do they smell like?" you say. The writer thinks awhile, and then says, "They smell like dirty gym shorts, like old hamburgers, like my eighth-grade math teacher's breath." The writer laughs, particularly fond of the final simile. Then she adds, "My boyfriend has a cat. A Tom. When he moved into his first apartment, that cat sprayed all over the place, you know, marking his territory. The place stunk so bad that I couldn't even go there for a week. Can you imagine? Your boyfriend gets his first apartment, and you can't even go in the place for a week?"

The writer has sparked your imagination; you think that she can spark her teacher's imagination as well. "Why don't you do your narrative about your boyfriend's cat? You could tell the story - or you could make up a story - about going over there for dinner, hoping for a romantic evening, and being put off by the cat." The writer likes this idea and goes off to write her draft. She returns with the following story about her boyfriend and his cat.

She was hoping for a romantic dinner; he was making her favorite meal. She could smell the T-bone and the apple pie before she even got to his door. But when she opened the door, her appetite was obliterated: the smell of cat spray smelled worse than her eighth-grade math teacher's breath. Of course, because she remained hopeful for a romantic evening, she put on her best face, tried not to grimace, and gave her boyfriend the flowers she'd picked up on the way. They chat; everything is going fine; he goes to the kitchen to check on dinner; she hears his shriek. The cat has stolen all of the food! Upon searching, they find the cat under the sofa, not only with their dinner, but with the writer's wallet, her favorite picture of her mom torn in half, her new leather jacket now full of cat hairs. This cat not only stinks, he's a thief as well. Still, the evening need not be a total waste. They order pizza, have some wine. She and her man talk; their moods improve, and she decides that it might be a nice time to kiss. She pulls the old yawn trick to get her arm around him, and just as she's ready to kiss him the cat jumps into his lap. "Oh, Pookie, Pookie, Pookie," her boyfriend says, giving himself over to the purring cat. "Damn lap cat," the writer says to herself, and leaves it at that. She has written a paper illustrating that cats are smelly, thieving, and middle class. She has fulfilled her thesis.

Now, you like this paper. It's got a great voice, and it's got humor. You feel, however, that the writer should refine the thesis. It has served the writer well in helping her to organize, control, predict, and define her essay; however, she needs now to consider how to choose words and a tone which will hook the reader and reel him in. You explain to the writer that her thesis can be humorous, that she can feel free to be extreme, because a funny, exaggerated thesis would suit this funny, exaggerated paper.

After some doodling and some dialogue, the writer comes up with the following thesis: "All cats should be exterminated because they are the stinking, kleptomaniacal darlings of the bourgeoisie." You laugh; you like it. Moreover, the thesis has given the writer an ending for her essay: she exterminates the cat in her boyfriend's microwave, convinces him to get a goldfish instead, and the two of them live happily ever after. The writer is happy. The tutor is happy. The paper works.

While you will likely not encounter a "cat" assignment at Dartmouth, this sort of experience with writing a thesis is a common one. Even when papers are more sophisticated than this one - even when the subject is Hitler's rise to power, or Freud's treatment of taboo - writers will often write a working thesis, one that guides them through the writing process. Then they will return to the thesis, sometimes several times before their paper is finished, revising it to better fit their paper's increasingly refined argument and tone.

Polishing the Thesis Sentence

Look at the sentence's structure. Is the main idea of the paper placed appropriately in the main clause? If there are parallel points made in the paper, does the thesis sentence signal this to the reader via some parallel structure? If the paper makes an interesting but necessary aside, is that aside predicted - perhaps in a parenthetical element? Remember: the structure of the thesis sentence also signals much to the reader about the structure of the argument. Be sure that the thesis reflects, reliably, what the paper itself is going to say.

As to the style of the sentence: hold the thesis sentence to the highest stylistic standards. Help a writer to make sure that it is as clear and concise as it can be, and that its language and phrasing reflect confidence, eloquence, and grace.

Kant’s Will at the Crossroads: An Essay on the Failings of Practical Reason

Kant's Will at the Crossroads

Jens Timmermann, Kant’s Will at the Crossroad: An Essay on the Failings of Practical Reason , Oxford University Press, 2022, 192pp., $80.00 (hbk), ISBN 9780192896032.

Reviewed by Andrews Reath, University of California, Riverside

Jens Timmermann’s essay aims to give us Kant’s account of ‘practical failure’, that is, of what happens when an agent ‘deviates from the demands of reason’ (2). In doing so, Timmermann develops a distinctive treatment of the principal ideas in Kant’s moral psychology and conception of rational agency. One guiding thread is to ‘re-assert’ (153), in opposition to a recent and influential interpretive trend, that Kant’s moral conception does indeed operate with several stark dualisms—between duty and happiness, between moral and non-moral motivation, between pure practical reason and the empirically conditioned use of practical reason. On Timmermann’s reading, Kant held that the human being is moved by two heterogeneous kinds of incentives (moral interests and the interest in happiness) that operate in radically different ways and that, as a result, the will—by which he means the faculty of choice [ Willkür ]—stands at a crossroads (as Kant says at G 4:400) and must choose between them.

On Timmermann’s reading these standard dualisms support another that is the central thesis of the book—that Kant accepted a ‘hybrid theory of practical failure. . .which points to a hybrid theory of practical rationality’ (6, 7). Is failure to conform to reason due to mistaken judgment about, or ignorance of, the good due to cognitive failure (as Socrates thought)? Or is it due to a conscious failure to act on one’s judgment about what is best, due to some sensible influence, in which case the failure is ethical (as Aristotle thought in opposition to his teacher)? Timmermann terms the first account ‘intellectualist’ and the second ‘volitional’. His striking thesis is that ‘Kant is committed to intellectualism about non-moral action while defending a strongly anti-intellectualist or volitional position in the realm of moral choice’ (6–7). In non-moral or prudential choice, either an agent’s failure to take the available means to a professed end is due to ignorance or mistaken judgment about the appropriate means; or it is due to the agent’s no longer wanting the end, or not wanting it enough to bear the costs of attaining it. Neither case is an instance of what is termed ‘true irrationality’, because one’s choice does not in fact diverge from one’s judgment of what is prudentially best. Practical failure in this domain is due to mistaken judgement, rather than choice that violates some distinctively practical principle. But, Timmermann argues, this account of practical failure does not ring true in the moral sphere. ‘Moral failure is not caused by some cognitive defect or a flawed piece of reasoning. It consists in the conscious, knowing, voluntary choice not to will the moral end’ (7). In prototypically moral failure we judge one action to be the morally good choice, but knowingly choose a different course (weakly, inexplicably, perversely, etc.).

Timmermann ascribes these differing accounts of practical failure to Kant on both textual and philosophical grounds, and his discussion of practical failure is a bridge to the hybrid account of practical rationality, which holds that choice is determined in radically different ways in the moral and non-moral domains. In prudential choice Kant is an intellectualist in the sense that choice and action are invariably determined by one’s judgment (e.g., of what one wants most, or of the proper means to one’s end). There is no gap between judgment and choice, and we do not knowingly choose contrary to our judgment. However, in the moral sphere rational deliberation and judgment are one thing, but choice is something further and choice can diverge from judgment. The faculty of choice is tasked with following the dictates of practical reason. But given the heterogeneity of the incentives by which human beings are moved, following the dictates of practical reason requires an elective act on the part of an agent that reflects or determines one’s character. In that sense, Kant is a ‘volitionist’ about moral choice.

The upshot, according to Timmermann, is that there is no unified account of practical rationality in Kant. One element of this dualistic reading is his claim that for Kant ‘there is no freedom in non-moral choice’ (4n.14)—a claim to which I will return.

Some background will help bring out the significance of Timmermann’s reading. The above dualisms are on display in the Analytic of the Critique of Practical Reason , where Kant draws a distinction between ‘practical laws’ deriving from the formal principle of morality based in reason a priori and ‘material practical principles’ that place the ground of choice in pleasure or the feeling of agreeableness ( KpV 5: 22ff.). In the Critique Kant treats this dichotomy as exhaustive, in that any principle of choice falls into one category or the other. Moreover, what unifies those in the second category (‘makes them wholly of the same kind’) is that they place the ground of choice in pleasure or the feeling of agreeableness—which Kant treats as affections ‘of one and the same vital force’—so that any principle of choice other than respect for moral principles—including, e.g., other-regarding principles based on affection or natural sympathy— falls under the ‘general principle of self-love or one’s own happiness’ ( KpV 5:22). And in Chapter II, Kant argues that absent an a priori law of pure practical reason, the only ground of choice is the subjective standard of what an agent finds agreeable.

Several commentators have looked for ways to soften these dichotomies and to find some continuity between moral and non-moral choice—often on purely interpretive grounds, but sometimes in an effort to nudge Kant in a direction that they find philosophically more acceptable. They grant the heterogeneity of moral and non-moral incentives and allow that they ground different deliberative processes. But they argue that Kant held (should have held?) that as different as these incentives are, they are taken up into choice on the same terms—through an act of reflective endorsement, or by taking the incentive to be an objectively sufficient ground of choice. The idea—and here is a variation of what Henry Allison has called Kant’s ‘Incorporation Thesis’—is that any incentive comes to influence choice by being taken up into practical self-consciousness as an item from which one can reason to action. Timmermann cites Christine Korsgaard, Allison, Stephen Engstrom, and myself as proponents of what he calls ‘intellectualism’ about moral choice. (I’m happy to be included in this august company, and though I prefer the term ‘cognitivism’, I will use ‘intellectualism’ in this review in deference to Timmermann.) Some readers find continuity between moral and non-moral choice to be inherently attractive, but in addition this approach has the specific advantage of allowing Kant to say that choices made on both moral and non-moral grounds are free (and imputable to the agent) in just the same sense. A difficulty for this approach is that, in addition to holding that morally neutral or innocent choice results from a judgment made on sufficient grounds, it must say the same about choices that are clearly morally bad—that in action that violates moral principle, an incentive influences choice through the agent incorrectly taking it to be an objectively sufficient ground of choice. [1] Does such a model allow for knowing and intentional wrong-doing, as Kant allows and which seems clearly possible? This concern is one of Timmermann’s reasons for defending an alternative approach that he finds truer to the texts.

Timmermann’s reading is striking for ascribing to Kant a hybrid theory of practical rationality—intellectualism about prudence and a volitional understanding of moral choice. Equally striking is his suggestion that the interpretive approach that he targets is the ‘mirror image’, favoring a volitional understanding of prudential and an intellectualist understanding of moral choice (128). One might think that one should have the same understanding of each domain, whatever that might be. Clearly there is still a lot to sort out here.

Timmermann’s book contains insightful discussions of many topics central to Kant’s conception of practical reason and to related contemporary discussions. The writing is admirably clear and to the point. There is much to be learned from his careful interpretive work and from his comments on the relevant secondary literature. I found almost all of the book to be instructive, even though I take the other side on several issues. Since his main claims deserve more detailed discussion than a short review permits, I’ll limit myself to pointing out some main building blocks of the hybrid conception that he ascribes to Kant.

Chapter 2 argues for the hedonistic reading of Kant’s conception of happiness as a sum of agreeable feeling (rather than overall desire satisfaction), stressing that for Kant the difficulty of forming a conception of happiness is uncertainty about what we will find agreeable. Timmermann emphasizes Kant’s idea that the quantity of expected pleasure is the single ‘volitional currency of prudential deliberation’ (27). This is an important element of the hybrid conception since it sets up the idea that human beings are moved by two heterogeneous kinds of interests (moral and prudential), between which there is, as it were, no rate of exchange.

Chapter 4 is a discussion of instrumental imperatives aimed at showing that so-called ‘“empirical practical reason” is not a mode of practical reason at all’ (46). On Timmermann’s reading ‘there is only one principle of practical reason: the categorical imperative (52).’ Noting Kant’s later view in the Critique of Judgment that hypothetical imperatives are ‘corollaries of theoretical reason ( KU 5:172),’ Timmermann sides with those who argue that Kant did not accept a single fundamental principle of instrumental rationality that, following Tom Hill’s classic paper, is often called ‘the Hypothetical Imperative’. There are then no distinctively practical principles of means-end rationality—neither particular hypothetical imperatives understood as genuinely practical principles nor a single fundamental principle of instrumental rationality. This idea sets up one line of argument for intellectualism in the prudential domain. If there are no genuinely practical principles of instrumental reason, there is no ‘true means-end irrationality’ in the sense of action that violates some such principle. But if practical failure in the prudential domain is not due to the violation of some practical principle, then it must be due to ignorance of or failure to grasp the relevant (theoretical) means-end connection. That supports the idea that prudential choice is directly determined by judgment (about what will bring about most satisfaction, etc.). Timmermann develops a more intuitive line of argument as well. It is hard to understand why an agent would not take the known and available means to an end that she wants, especially if we assume that agreeable feeling is the single volitional currency in the prudential domain—indeed, so hard to understand that it could never happen (cf. 65). If one is not taking the available means to something that one wants on the grounds of expected pleasure, that must be due either a) to a mistaken judgment about the means or b) to the agent’s now finding some alternative more appealing (in which case there is no practical failure) (see 8, 57, 109).

One problem that I see is that Timmermann supports this point through very simple examples, such as taking steps to make good coffee or good bread. In cases where the means to a happiness-based end is clearly known and available, it is hard to understand how someone with the end can fail to take the means, and we conclude that they changed their mind about the end. Here the intellectualist account that draws a straight line between means-end judgment and choice is compelling. However, I do not see that such cases rule out the possibility of more complex cases of true means-end irrationality—where an agent fails to take the known, available but difficult steps to what she clearly believes will bring greater happiness, cases where volitional failure (out of weakness, distraction or indecision) is plausible. Philosophers are divided over this issue and though Timmermann’s discussion is carefully framed, I doubt that it will settle either the philosophical issue or what Kant thought.

Chapter 6 raises important challenges to the ‘intellectualist’ conceptions of moral choice mentioned above (namely that rational choice is constitutively guided by a judgment of sufficient reasons). First, it contains a valuable discussion of Allison’s ‘Incorporation Thesis’, arguing that this thesis does not clearly support ‘intellectualism’ about moral choice. Allison’s concern was to identify the element of spontaneity that is central to Kant’s conception of free choice across the board, and he does not explicitly position himself as supporting an ‘intellectualist’ conception of ‘incorporation’. (In fact, there is ambiguity in the notion of ‘incorporating an incentive into a maxim’. Is ‘incorporation’ a bare elective act, the simple adoption of a maxim? Or does it involve an element of normatively guided judgment or endorsement?) Timmermann’s contribution is to bring out the cognitivist slant to Allison’s reading (namely that to incorporate an incentive into a maxim is to endorse a general principle that treats the incentive as a sufficient ground of choice) and to show that another interpretation is possible, here getting into the weeds with alternate readings of passages from Kant’s Lectures on which Allison draws. The main thrust of Timmermann’s discussion is that ‘incorporation’ is an act of Willkür , of the faculty of choice. But on the standard reading of this distinction, while Wille is a deliberative capacity (it is ‘practical reason itself’ ( MdS 6: 213)), Willkür is a purely elective capacity. As Timmermann writes, given that ‘rational assessment cannot be the task of Willkür . . .why not assume that incorporation is an elective, not an evaluative act? (97)’ Human beings are moved by heterogeneous and incommensurable motives, and we must choose which to prioritize. A second challenge is the difficulty for the ‘intellectualist’ of accommodating the phenomenon of knowingly acting against one’s moral judgement (102–6). Timmermann cites several passages in which Kant clearly allows for this possibility. The question for the ‘intellectualist’ here is how to accommodate these passages and, more importantly, this phenomenon.

Can the ‘intellectualist’ respond to these clearly legitimate challenges? I think that there is textual support for the ‘intellectualist’ position, though granted there are texts that run in the other direction. One might not find a decisive answer in what Kant says. [2] But there are systematic considerations as well. There is a general worry that the ‘volitional conception’ detaches moral choice from practical reasoning and judgment in ways that make it arbitrary and ungrounded. Should we attribute such a view to Kant? More generally, does an elective conception of choice fit into a general conception of the will as a rational power that is exercised according to its own constitutive principle? Is there room in that conception of the will for a purely elective capacity whose exercise, though subject to normative (moral) assessment, is itself normatively ungrounded? (Timmermann will certainly say ‘Yes,’ while I say: ‘Perhaps Not’.) These are complicated issues that need more discussion than this review permits. One virtue of Timmermann’s essay is to have raised them so clearly.

One recurring theme in the essay is that prudential choice is not free: ‘there is no freedom in empirically conditioned practical choice, which might just as well be mechanical, because the spontaneity involved is relative to antecedent purposes rather than absolute’ (98). (See also 4n14, 8, 24, 120, 156.) Initially these remarks puzzled me because they come close to saddling Kant with the ‘Reinhold problem’—that only morally good choice is free, that morally bad choice is not free and therefore not imputable. But Timmermann does not saddle Kant with this problem. Rather he is articulating the standard Kantian idea that free agency is only manifest or most fully realized in action motivated by respect for moral principle. But then does Timmermann’s reading leave room for a sense in which all choice across the board is free?

I understand his reading as follows: Genuine freedom requires the capacity to choose between radically different alternatives. That is, it requires both that agents face motivational alternatives of an entirely different kind and that they have the capacity to choose between them. Furthermore, freedom requires a capacity for genuine self-determination. Human beings satisfy these conditions. We are moved by incentives that operate in ‘different volitional currencies,’ and we have the capacity to choose between them. Furthermore, that capacity is a capacity for self-determination because it gives us the ability to set aside sensible interest and to act from principles that reason gives to itself. Human beings then have the capacity for free agency. Where only prudential considerations rooted in the expectation of agreeable feeling are at issue, we can move almost ‘mechanically’ from such considerations to choice; in that respect prudential choice does not draw on our free/moral capacity. But since moral considerations are always on the table, in any choice situation where we find reason to, we can bracket prudential interest and follow moral principle. (So the existence of free/moral capacity settles the issue of responsibility.)

I suspect that there is another piece to this puzzle. One might think that, given the ever-presence of morality, whenever agents act from prudence, they have elected to—that is, they did in fact side with that basic alternative. That is to say that they have exercised a capacity for elective choice that does not draw on specifically moral capacity (but which could at any time). Is that a sense in which all choice across the board is free? These are delicate issues that Timmermann might address more explicitly.

Kant’s Will at the Crossroad develops a comprehensive approach to Kant’s conception of practical rationality supported by careful reading of the principal texts. By re-affirming several (familiar) dualisms that other commentators have played down, it lays out an alternative to one influential trend in recent Kant scholarship. These issues are subtle and complex, and we should be grateful to Jens Timmermann for putting them on the table so clearly and giving us the opportunity to think them through once more.

Science Improves When People Realize They Were Wrong

Science means being able to change your mind in light of new evidence

By Naomi Oreskes

Illustration of multiple researchers in a lab smacking the palm of their hand on their heads

Scott Brundage

Many traits that are expected of scientists—dispassion, detachment, prodigious attention to detail, putting caveats on everything, and always burying the lede—are less helpful in day-to-day life. The contrast between scientific and everyday conversation, for example, is one reason that so much scientific com­­munication fails to hit the mark with broader audiences. (One ob­server put it bluntly : “Scienti­­fic writing is all too often ... bad writing.”) One aspect of science, however, is a good model for our behavior, especially in times like these, when so many people seem to be sure that they are right and their opponents are wrong. It is the ability to say, “Wait—hold on. I might have been wrong.”

Not all scientists live up to this ideal, of course. But history offers admirable examples of scientists admitting they were wrong and changing their views in the face of new evidence and arguments. My favorite comes from the history of plate tectonics.

In the early 20th century German geophysicist and meteorologist Alfred Wegener proposed the theory of continental drift, suggesting that continents were not fixed on Earth’s surface but had mi­­grated widely during the planet’s history. Wegener was not a crank: he was a prominent scientist who had made important contributions to meteorology and polar re­­search. The idea that the now separate continents had once been somehow connected was supported by extensive evidence from stratigraphy and paleontology—evidence that had already inspired other theories of continental mobility. His proposal did not get ignored: it was discussed throughout Eur­ope, North America, South Africa and Australia in the 1920s and early 1930s. But a majority of scientists rejected it, particularly in the U.S., where geologists objected to the form of the theory and geophysicists clung to a model of Earth that seemed to be incompatible with moving continents.

Blackett of Imperial College London, Harry Hammond Hess of Princeton University, John Tuzo Wilson of the University of Toronto and Edward Bullard of the University of Cambridge—endorsed the idea of continental motions. Between 1967 and 1968 this revival began to coalesce as the theory of plate tectonics.

Not, however, at what was then known as the Lamont Geological Laboratory, part of Columbia University. Under the direction of geophysicist Maurice Ewing, Lamont was one of the world’s most respected centers of marine geophysical research in the 1950s and 1960s. With financial and logistical support from the U.S. Navy, Lamont researchers amassed prodigious amounts of data on the heat flow, seis­micity, bathymetry and structure of the seafloor. But Lamont under Ewing was a bastion of resistance to the new theory.

It’s not clear why Ewing so strongly opposed continental drift. It may be that having trained in electrical engineering, physics and math, he never really warmed to geological questions. The evidence suggests that Ewing never engaged with Wegener’s work. In a grant proposal written in 1947, Ewing even confused “Wegener” with “Wagner,” referring to the “Wagner hypothesis of continental drift.”

And Ewing was not alone at Lamont in his ignorance of de­­bates in geology. One scientist recalled that in 1965 he personally “was only vaguely aware of the hy­­pothesis” [of continental drift] and that colleagues at Lamont who were familiar with it were mostly “skeptical and dis­missive.” Ewing was also known to be auto­cratic; one oceanographer called him the “oceanographic equivalent of General Patton.” It wasn’t an environment that en­­couraged dissent.

One scientist who did change his mind was Xavier Le Pichon . In the spring of 1966 Le Pichon had just defended his Ph.D. thesis, which denied the possibility of regional crustal mobility. After seeing some key data at Lamont—data that had been presented at a meeting of the American Geophysical Union just that week—he went home and asked his wife to pour him a drink, saying, “The conclusions of my thesis are wrong.”

Le Pichon had used heat-flow data to “prove” that Hess’s hypothesis of seafloor spreading—the idea that basaltic magma welled up from the mantle at the mid-­oceanic ridges, creating pressure that split the ocean floor and drove the two halves apart—was incorrect. Now new geomagnetic data convinced him that the hypothesis was correct and that something was wrong with either the heat-flow data or his interpretation of them.

Le Pichon has described this event as “extremely painful,” explaining in an essay that “during a period of 24 hours, I had the im­­pres­sion that my whole world was crumbling. I tried desperately to reject this new evidence.” But then he did what all good scientists should do: he set aside his bruised ego (presumably after polishing off that drink) and got back to work. Within two years he had co-­authored several key papers that helped to establish plate tectonics. By 1982 he was one of the world’s most cited scientists—one of only two geophysicists to earn that distinction.

In the years that followed, Lamont scientists made many crucial contributions to plate tectonics, and Le Pichon became one of the leading earth scientists of his generation, garnering numerous awards, distinctions and medals, including (ironically) the Maurice Ewing Medal from the American Geophysical Union. In science, as in life, it pays to be able to admit when you are wrong and change your mind.

  • Be aware of who, when, and what you're messaging, use emoji and acronyms sparingly, and always use proper spelling and grammar.

Regardless of whether you text, or use a dedicated messaging app such as iMessage or WhatsApp, there are certain rules you should follow. Unfortunately, not everyone seems to have gotten the memo listing the fundamental messaging etiquette everyone should know. So here, to help you out, are 11 dos and don'ts I always adhere to...

1 Avoid Shatner Messaging (A Series of Short Messages)

An example of Shatner messaging via text

While you may not be familiar with the term "Shatner messaging," you will likely be familiar with what it refers to. This is, simply, a series of short messages sent quickly when one longer message would have sufficed. The worst offenders may even send one word at a time for dramatic effect, creating endless notifications on your phone.

The name references the way William Shatner of Star Trek fame speaks. He has a tendency to add pauses between words and that matches the style of messaging being used here. Whatever you choose to call it, please stop doing it.

2 Never Write Long Essays Without a Pause

An example of a long essay via text

In direct converse to Shatner messaging, some people write long essays as messages, and that's just as unnecessary. Even if you have a major point to make to someone, take pity on their soul by not sending them a long, rambling message that covers multiple subjects all at once.

Instead, focus on one subject, and send the message. Then allow them to respond before moving onto a different subject. If you imagine how this would feel in a real-world conversation rather than an online message, you can easily see how inappropriate and unnecessary it is.

3 If You Read a Message, Always Acknowledge It

An example of a lack of acknowledgment to a text

We all have that one friend who lets a conversation on a messaging app run out without acknowledging that it's ending. And we all know that it is rude. You should always acknowledge a message in some way, even if it's just a tick or thumbs-up emoji. It lets the other person know you've seen it and are ready to move on.

Why is this rude? Well, imagine you were talking to someone face-to-face, and they just walked off without bringing the conversation to a conclusion in any way. You would be annoyed, and rightly so. And we need to employ the same basic level of politeness in our online interactions too. We should even be polite to AI chatbots !

4 Don't Nag Someone to Reply to You Quickly

A message begging for acknowledgment of receipt

While it's tempting to metaphorically poke someone when they haven't replied to a message immediately, it's also rude. They may be busy, so unless you know that they're online and available, give them the benefit of the doubt.

However, there is a limit to this. As already mentioned, it is rude to completely ignore someone's message, so if they haven't replied or acknowledged it in some other way, say 24 hours later, you're well within your rights to send a follow-up message.

5 Be Aware of the Time You're Messaging Someone

A message apologizing for texting late

With the planet now interconnected like never before, you will likely have family and friends located all over the world. And messaging allows you to communicate with them freely and easily like never before. But you need to be aware of the different time zones that exist.

I work with a lot of Americans, and they know not to message me during the evening their time, as it would be the early hours of the morning for me here in the UK. While most people use Do Not Disturb to stop this from being an issue, you should also be aware of what time (in their timezone) you're messaging someone.

6 Remember Who It Is That You're Messaging

A text message about an edgy joke

It's often easy to forget that different recipients require different types of messages. For example, I speak very differently in family WhatsApp groups than I do in groups containing similarly-aged and similarly-minded friends. Because what you say and how you say it should differ between different sets of people.

As well as talking differently to friends than you do to family, you should also soften your tone in conversations with work colleagues or your boss. They may not appreciate the risqué picture you meant to send to your significant other, or the joke you meant to send to your friends.

7 Never Send Anything Inappropriate Via a Message

A message apologizing for a rude joke

Even if you think the recipient will appreciate what you're sending, you should always think twice before sending anything inappropriate. This can range from the aforementioned risqué pictures and edgy jokes to anything containing personal or sensitive information.

I would even urge caution when badmouthing one friend to another, as messages can be screenshotted and used against you. Screenshots can also accidentally dox you , but that's another issue entirely. Friends come and go, and if you have messaged the wrong thing to a friend you then fall out with, that wrong thing could be used against you.

8 Use Emojis Sparingly (and Appropriately)

A text message full of emojis

For many of us, emojis have become the default way to react to things we see online, including messages. And that's absolutely fine. I love them as much as the next person, as they give us all a shortcut way of acknowledging something.

However, you can use emojis too often, and if you do so, not only do they lose their impact, you'll start to look lazy and uncaring. Emojis (such as a thumbs-up or a laughing face) are good when a message doesn't justify an actual response, but not when you're asked a direct question or speaking about something serious.

9 Always Use Proper Spelling and Grammar

A text message filled with spelling and grammar mistakes

This messaging rule likely won't go down with younger generations, many of whom see proper spelling and grammar as entirely optional demands. But I think everyone should at least strive to spell words correctly, and place commas where (and only where) they need to be placed in all forms of written communication.

All the way back in 2012, I wrote an article about why typos always matter, even in text messages . And while the world has moved on a lot since then, with messaging apps taking over from SMS text messages, I still believe my point remains valid.

10 Never Assume That Everyone Knows Text Slang

A text message filled with acronyms and slang

Acronyms are commonly used when messaging people, mainly because SMS text messages have a certain number of characters, meaning any opportunity to reduce the number of characters used was useful. But not everyone knows every acronym out there.

Generally speaking, the older you are, the worse this problem becomes. New acronyms and shorthand are being invented all the time, with many making it into the dictionary. But any that don't pass into the mainstream can be confusing to the rest of the population. So try to use full words when possible, even if it takes longer to write out.

11 Never Message Someone When You're Tired or Inebriated

A text message sent when inebriated

You should never, ever message anyone when you're tired or inebriated. Essentially, if your rational mind is unlikely to be working at full capacity for any reason whatsoever, you should bar yourself from messaging people. Even if that means locking your phone away somewhere inaccessible.

Why? Because you may have lost that instinct not to offend, and/or lost your inhibitions. This means you may end up messaging that ex-girlfriend you think about occasionally, or end up sending the wrong message to the wrong person.

These are a few of the rules to keep in mind when messaging others. Not only will they make sure that you don't come across as rude, but they also could prevent you from landing in awkward situations.

Online crowds wield power, for good and bad

By tom fleischman, cornell chronicle.

How do online crowds form, grow and behave? How do they wield influence? What distinguishes desirable crowd activism from mob harassment?

In the summer of 2022, Cornell Tech and Cornell Law School professor  James Grimmelmann and postdoctoral fellow Charles Duan hosted a virtual workshop in which participants attempted to answer these questions and more.

At the end of the two-day online workshop Grimmelmann, the Tessler Family Professor of Digital and Information Law at Cornell Tech and at Cornell Law School, and co-organizer Duan, now an assistant professor of law at American University’s Washington College of Law, asked participants to reflect on the conversations and identify important themes about platforms and crowds.

Barons and the Mob book cover

The result: “ The Barons and the Mob: Essays on Centralized Platforms and Decentralized Crowds,” an introduction to the complexities of online crowds and the importance of understanding their nature in the context of efforts toward online platform regulation.

The introduction references a pair of online user “revolts.” In 2007, one of the users of news aggregator Digg posted an encryption key that could be used to circumvent copyright protection on Blu-Ray discs. Sixteen years later, Grimmelmann and Duan wrote, “history rhymed with itself” when Reddit, in preparation for a rumored IPO, started charging developers to access its previously free application programming interface. Users of both platforms rose up in revolt. In Digg’s case, the crowd won the revolt – not so with Reddit.

“The Digg disruption and the Reddit rebellion,” they wrote, “demonstrate the conflict between the two great sources of power on the Internet: the centralized platforms that control the infrastructure of online communities, and the decentralized crowds of users who come together in them.”

In all, a dozen experts share their perspectives in “The Barons and the Mob,” tackling what makes an online crowd; the influence of money on crowds; identifying misinformation; authenticity; network economics and other topics.

Grimmelmann spoke with the Chronicle about the essay collection:

Question: What was the impetus behind the workshop?

Answer: The idea came out of seeing some of the ways that crowds were self-consciously being weaponized for political and commercial purposes. The “to the moon” sentiment of the  wallstreetbets subreddit wasn’t all that different from the kind of online energy associated with political movements or with influencer beefs. But platforms seemed to consider some of these crowds to be serious problems they had to block, and some of them to be benign intended uses. That paradox led us to look more closely at how platforms and crowds related to each other.

Q: Are there other moments in history that radically changed the dynamic between the “barons” and the “mob” – perhaps the invention of the printing press?

A: The printing press definitely helped catalyze new kinds of distributed groups, from scientific collaborations to journalism for “the public.” The age of revolution – starting especially with the French Revolution – demonstrated the dramatic power of the mob on the street compared with old aristocratic hierarchies. The mobs prevailed in the long run: Old forms of centralized power were swept aside and gave way to new political forms that were more responsive to mass public sentiment.

Q: Has the power dynamic between platforms and crowds morphed over time? Have crowds learned how to wield greater power over the last 20 to 30 years?

A: The Reddit moderator revolt last summer was a really striking moment, because Reddit explicitly decided that it was willing to take on the full power of a highly organized user group. It was a big bet, and Reddit basically won: Its IPO went ahead, and today the site has much more effective power over its user base. The pendulum seems to have swung in the direction of the platforms; they’re better able to predict and steer crowd dynamics than they were a few years ago.

You can see TikTok as an extreme example of this trend: The site harnesses crowd energy and enthusiasm but systematically works to prevent crowds from forming and sustaining themselves in ways that would form durable power alternatives.

Q: Do you see an ultimate “winner” in this push-and-pull between the “lords” (platforms) and the “commoners” (users)? Can there ever be a winner?

A: No – the tension is eternal. Without either of these forms, social media wouldn’t function. Platforms need crowds in order to be viable businesses, and crowds need platforms as a place to gather. They each have an interest in the other’s existence.

Q: Are there other big questions to be addressed in this space?

A: Yes – we don’t know how online crowds are catalyzed and controlled. We don’t know how to think about them as groups with agency for economic purposes. We don’t know what legitimate and effective forms of moderation to respond to them look like. We don’t know how regulations will go awry when crowds respond to them. And there are many more: This report is just a starting point, and a way of inviting people to think seriously about these issues.

  • The trial of Lucy Letby has shocked British statisticians

And shown that many Britons are woefully ignorant of statistics

Collage of Chris Whitty and Boris Johnson in front of a bar chart. Johnson looks confused at the data when Whitty looks leveled.

Your browser does not support the <audio> element.

I t was “feeble”. It was “very unsatisfactory”. It was, in short, “terrible”. If you wish to annoy a statistician, ask them about the trial of Lucy Letby, a British nurse. Statisticians will, typically, take no view whatsoever on the guilt or otherwise of Ms Letby, who in August 2023 was found guilty of murdering seven very young babies in a hospital near Liverpool between 2015 and 2016, and given 15 life sentences without the chance of parole.

They do, however, have very strong views on the way her trial—which relied in part on analysis of hospital rotas—proceeded. “The conviction is unsafe,” says Peter Green, a maths professor at Bristol University. It was the kind of case “that leaves a bad taste in the mouth,” says Philip Dawid, a statistics professor at Cambridge University. Statisticians were “shocked”, another eminent professor explains, by the way the trial weighed the probability of seemingly extraordinary events.

Britain has a problem. Not, in fact, a murder problem (with 1.1 murders per 100,000 people, Britain is not bad by global standards). Nor does it have a problem with producing scientists who can work out such things—and considerably more besides (with eight Fields medals and around a hundred science Nobels, Britain is above average at higher-level maths). Instead, it has a problem with producing non-scientists—such as politicians or, say, lawyers in a murder case—who can understand data. When it comes to this, says Sir Adrian Smith, the head of the Royal Society, Britain is “very bad” indeed.

This is not a new diagnosis. In a 1959 lecture called “The Two Cultures”, the scientist and writer C.P. Snow warned that society was “being split into two polar groups”: those who understood science and those who did not. Worse, the bookish types did not even know what they did not know. Literary intellectuals smirk at the illiteracy of scientists but, Snow said, ask them to describe the second law of thermodynamics (“the scientific equivalent of ‘Have you read a work of Shakespeare’s?’”) or even to define mass (“the scientific equivalent of saying, Can you read? ”) and the answer would be a “cold” negative.

Snow felt, 65 years ago, that this smirking incomprehension was a “joke which has gone sour”. It is sourer still in 2024. The trial of Ms Letby is one example. Covid furnished far more: such as how Boris Johnson was, as one adviser put it, “bamboozled” by science and “struggled with the whole concept of doubling times”; or how politicians failed to grasp concepts like absolute and relative risk. Dame Kate Bingham, who chaired Britain’s vaccine taskforce, was “pretty shocked” by the level of scientific ignorance in the civil service. Worse, she felt that, for some, it is almost “a badge of honour”.

Mr Johnson is paradigmatic of what has gone wrong. He is not—despite what his actions often imply—a stupid man and certainly not, after Eton and Oxford, an ill-educated one. His education was etiolated; it was not ineffectual. He could read Archimedes in the original; he could not begin to understand Archimedes’s maths. He is the product of what Snow called Britain’s “fanatical belief in educational specialisation”. And that belief, says David Willetts, a former universities minister, is “as acute as ever”.

The problem is not that A-levels are very bad. It is worse: they are very good. An A-level physics student “probably knows more physics than any other 18-year-old in any other Western country,” says Lord Willetts. Arts students are similarly specialised: when cramming for university, the would-be historians in Alan Bennett’s play, “The History Boys”, debate such arcane topics as the 14 foreskins of Christ found in medieval reliquaries. They do not touch on chemistry. This matters. To evaluate an education system, the crucial question is not whether someone who is studying physics understands it; it is whether someone who is not does.

And that is the question Britain cannot get right. In 2010 the Nuffield Foundation, a think-tank, decided to test whether Britain was really so bad at offering educational breadth by comparing it with 24 other countries, mostly drawn from the OECD , a rich-country club. In England fewer than one in five students studied maths after 16. In 18 of the countries more than half did; in eight, everyone did. Government data suggest that almost half of the working-age population in Britain have the numeracy skills of a primary school child.

Not all of Snow’s thesis has dated well. He over-emphasised scientific knowledge; having a scientifically literate population is actually less about knowing facts than having “an attitude of mind”, says Sir David Spiegelhalter, emeritus professor of statistics at Cambridge. But Snow’s analysis of English education still stands.

The solution is not to get everyone to do A -Level maths: it is too hard and, besides, there are too few teachers. Instead, as a forthcoming Royal Society report will argue, maths and data analysis should be woven into all education up to 18. Something is certainly needed: for people in positions of authority not to have basic quantitative literacy is “unacceptable”, says Professor Spiegelhalter.

And yet it is widely accepted. Newspapers frequently run stories on the percentage of politicians, judges or civil servants who went to private schools. There are far fewer stories on what percentage are from arts rather than science backgrounds. But it is high—and always has been. The original Victorian civil service exams, designed by the classicist Benjamin Jowett, gave the most marks not to science but classical literature. “Name the first and last of the 12 Caesars,” ran a typical question.

Arts students still dominate. Statistics on the numbers of civil servants with STEM qualifications are hazy; but most estimates put them at around 2–7%. In America, it is almost 16%; in South Korea, around 30%. How, asks Dame Kate, could you possibly run a business department in a 21st-century government with “nobody who knows anything about business or science?”

Lawyers are little better. Even before Ms Letby’s trial began, statisticians were “apprehensive”, says Professor Green. There had been recent miscarriages of justice in which so-called “health-care serial-killers” had been convicted using bad statistics. Moreover, the history of law and statistics in Britain is dismal. In the 1990s, a mother was convicted of murdering her baby sons after Roy Meadow, a paediatrician, claimed (erroneously) that the chances of their deaths being accidental was 1 in 73m. Professor Dawid was called to counter this claim. Before he could speak, the judge dismissed him: it was “hardly rocket science”.

Professor Dawid was “disgusted”—but not surprised. What alarms statisticians is not merely lawyers’ knowledge of stats (which, says Professor Dawid, is usually “dire”). It is, says Professor Spiegelhalter, their lack of awareness. Before the Letby trial, Professor Green and some colleagues therefore produced a booklet titled “Healthcare serial killer or coincidence?”

In previous cases, says Professor Green, rotas would be used to show that a particular nurse was always on duty when people were killed. Non-experts would then say: “You can’t possibly believe this could happen by chance. Therefore she is guilty”. The reasons why this logic is wrong are complex—and outlined in that booklet, now on the Royal Statistical Society website. But suffice to say that statisticians call this “painting the target around the arrow”.

Yet, in the Letby trial, a chart was used to show that she had been on duty when babies had died or collapsed unexpectedly; the jury was not told about other deaths for which she was not charged. The statistical weaknesses of this were not sufficiently pointed out. The target was painted around the arrow. She was convicted.

In 1959 Snow wrung his hands. But recognition of the narrowness of British education and the problems caused by statistical ignorance are growing. Snow observed that most felt our education system was bad but “nearly everyone feels that it is outside the will of man to alter it.” With luck, in 2024, it will not be. ■
