Writing a Paper: Thesis Statements

Basics of thesis statements.

The thesis statement is the brief articulation of your paper's central argument and purpose. You might hear it referred to as simply a "thesis." Every scholarly paper should have a thesis statement, and strong thesis statements are concise, specific, and arguable. Concise means the thesis is short: perhaps one or two sentences for a shorter paper. Specific means the thesis deals with a narrow and focused topic, appropriate to the paper's length. Arguable means that a scholar in your field could disagree (or perhaps already has!).

Strong thesis statements address specific intellectual questions, have clear positions, and use a structure that reflects the overall structure of the paper. Read on to learn more about constructing a strong thesis statement.

Being Specific

This thesis statement has no specific argument:

Needs Improvement: In this essay, I will examine two scholarly articles to find similarities and differences.

This statement is concise, but it is neither specific nor arguable—a reader might wonder, "Which scholarly articles? What is the topic of this paper? What field is the author writing in?" Additionally, the purpose of the paper—to "examine…to find similarities and differences" is not of a scholarly level. Identifying similarities and differences is a good first step, but strong academic argument goes further, analyzing what those similarities and differences might mean or imply.

Better: In this essay, I will argue that Bowler's (2003) autocratic management style, when coupled with Smith's (2007) theory of social cognition, can reduce the expenses associated with employee turnover.

The new revision here is still concise, as well as specific and arguable.  We can see that it is specific because the writer is mentioning (a) concrete ideas and (b) exact authors.  We can also gather the field (business) and the topic (management and employee turnover). The statement is arguable because the student goes beyond merely comparing; he or she draws conclusions from that comparison ("can reduce the expenses associated with employee turnover").

Making a Unique Argument

This thesis draft repeats the language of the writing prompt without making a unique argument:

Needs Improvement: The purpose of this essay is to monitor, assess, and evaluate an educational program for its strengths and weaknesses. Then, I will provide suggestions for improvement.

You can see here that the student has simply stated the paper's assignment, without articulating specifically how he or she will address it. The student can correct this error simply by phrasing the thesis statement as a specific answer to the assignment prompt.

Better: Through a series of student interviews, I found that Kennedy High School's antibullying program was ineffective. In order to address issues of conflict between students, I argue that Kennedy High School should embrace policies outlined by the California Department of Education (2010).

Words like "ineffective" and "argue" show here that the student has clearly thought through the assignment and analyzed the material; he or she is putting forth a specific and debatable position. The concrete information ("student interviews," "antibullying") further prepares the reader for the body of the paper and demonstrates how the student has addressed the assignment prompt without just restating that language.

Creating a Debate

This thesis statement includes only obvious fact or plot summary instead of argument:

Needs Improvement: Leadership is an important quality in nurse educators.

A good strategy to determine if your thesis statement is too broad (and therefore, not arguable) is to ask yourself, "Would a scholar in my field disagree with this point?" Here, we can see easily that no scholar is likely to argue that leadership is an unimportant quality in nurse educators.  The student needs to come up with a more arguable claim, and probably a narrower one; remember that a short paper needs a more focused topic than a dissertation.

Better: Roderick's (2009) theory of participatory leadership  is particularly appropriate to nurse educators working within the emergency medicine field, where students benefit most from collegial and kinesthetic learning.

Here, the student has identified a particular type of leadership ("participatory leadership"), narrowing the topic, and has made an arguable claim (this type of leadership is "appropriate" to a specific type of nurse educator). Conceivably, a scholar in the nursing field might disagree with this approach. The student's paper can now proceed, providing specific pieces of evidence to support the arguable central claim.

Choosing the Right Words

This thesis statement uses large or scholarly-sounding words that have no real substance:

Needs Improvement: Scholars should work to seize metacognitive outcomes by harnessing discipline-based networks to empower collaborative infrastructures.

There are many words in this sentence that may be buzzwords in the student's field or key terms taken from other texts, but together they do not communicate a clear, specific meaning. Sometimes students think scholarly writing means constructing complex sentences using special language, but actually it's usually a stronger choice to write clear, simple sentences. When in doubt, remember that your ideas should be complex, not your sentence structure.

Better: Ecologists should work to educate the U.S. public on conservation methods by making use of local and national green organizations to create a widespread communication plan.

Notice in the revision that the field is now clear (ecology), and the language has been made much more field-specific ("conservation methods," "green organizations"), so the reader is able to see concretely the ideas the student is communicating.

Leaving Room for Discussion

This thesis statement is not capable of development or advancement in the paper:

Needs Improvement: There are always alternatives to illegal drug use.

This sample thesis statement makes a claim, but it is not a claim that will sustain extended discussion. This claim is the type of claim that might be appropriate for the conclusion of a paper, but in the beginning of the paper, the student is left with nowhere to go. What further points can be made? If there are "always alternatives" to the problem the student is identifying, then why bother developing a paper around that claim? Ideally, a thesis statement should be complex enough to explore over the length of the entire paper.

Better: The most effective treatment plan for methamphetamine addiction may be a combination of pharmacological and cognitive therapy, as argued by Baker (2008), Smith (2009), and Xavier (2011).

In the revised thesis, you can see the student make a specific, debatable claim that has the potential to generate several pages' worth of discussion. When drafting a thesis statement, think about the questions your thesis statement will generate: What follow-up inquiries might a reader have? In the first example, there are almost no additional questions implied, but the revised example allows for a good deal more exploration.

Thesis Mad Libs

If you are having trouble getting started, try using the models below to generate a rough model of a thesis statement! These models are intended for drafting purposes only and should not appear in your final work.

• In this essay, I argue ____, using ______ to assert _____.
• While scholars have often argued ______, I argue______, because_______.
• Through an analysis of ______, I argue ______, which is important because_______.

Words to Avoid and to Embrace

When drafting your thesis statement, avoid words like explore, investigate, learn, compile, summarize , and explain to describe the main purpose of your paper. These words imply a paper that summarizes or "reports," rather than synthesizing and analyzing.

Instead of the terms above, try words like argue, critique, question , and interrogate . These more analytical words may help you begin strongly, by articulating a specific, critical, scholarly position.

More About Thesis Statement

What is a thesis statement .

In academic writing, a thesis statement is generally a sentence or two that summarizes the main point that an essay, research paper, or speech is making. It is typically located at the end of the introductory paragraph(s).

Thesis statements are kind of like roadmaps, laying out for the reader/listener where the writer/speaker is headed (argument) and how they are going to get there (evidence).

The thesis statement is widely taught in the humanities, especially in English classes in high school and college, to teach students how to make persuasive arguments that cite and analyze evidence and examples researched from literary, historical, or other texts.

Why is a thesis statement important in an essay?

Thesis comes from a Greek word that literally means “a setting down.” In the 300s BC, Aristotle defined thesis as when a philosopher puts forth a new idea that conflicts with general opinion.

Fast forward to today, when we use thesis to mean a “proposition” or “argument” one formally presents and defends. In academic settings, a thesis can be short for a thesis statement (our focus here) in an essay or shorter research paper. It can also be used for those much, much longer dissertations graduate students research, write, and defend for their degree (e.g., master’s thesis or doctoral thesis ).

Let’s look at statement real quick. It is a declaration or assertion. Sound redundant? The idea is that a thesis statement is the point in a paper or presentation that explicitly states the thesis. Usually in a sentence or two, the thesis statement summarizes the argument that’s going to be developed in the evidence and examples to come.

So, a thesis statement is just a sentence that gets the main point across. But, learning how to write these ain’t easy. That’s why educators, especially in English classes in high school and college, spend a lot of time teaching students how to craft effective thesis statements.

Why? Because in school, work, and life, we have to persuade people of our ideas and our point of view. These ideas might concern an analysis of literature or history, like a play by Shakespeare or a moment in the Civil Rights Movement. Or, these ideas might be a call to action, such as eating a certain diet or pursuing a business strategy.

How to write a thesis statement

There are many ways to make an effective thesis statement , but here are some general tips to follow.

So, let’s say you read a text, Shakespeare’s Twelfth Night , or researched a topic, the health benefits of kale. Then you formed an opinion about it—a claim you want to make about it and why others should care. You found evidence—quotes, examples, facts, statistics—in your resources that you think back up your argument. Your thesis statement brings all these together: point of view , evidence , and significance . It lays out where the entire paper or presentation is going, which is why educators often liken it to a roadmap .

Here’s an example:

Kale is good for you because it is nutrient-dense, cancer-fighting, and loaded with antioxidants.

The argument here—which a first-year high-schooler might make in a persuasive essay—is that “kale is good for you” (despite how some think it tastes). The claims it’s using to back up this assertion are that it’s 1) “nutrient-dense”; 2) “cancer-fighting”; and 3) “loaded with antioxidants.” The reader can expect that the rest of the essay will develop these claims, that is, cite and analyze evidence for them.

Here’s a thesis statement for a literary analysis of Shakespeare’s Twelfth Night. This resembles more of a college-level example:

Shakespeare’s Twelfth Night suggests that, when women do not reciprocate a man’s love, they are unjustly made out to be sexually deviant. This is illustrated in how the character Olivia is condemned as asexual because of her rejection of Duke Orsino.

Note how this thesis statement makes its claim in two sentences. Its argument centers on how women characters are vilified when they reject a man, and its evidence will be interactions between characters in Shakespeare’s play.

What are real-life examples of thesis statement ?

The term thesis statement is generally used by teachers and students in junior high, high school, and college, especially in English, Social Studies, and other classes in the humanities.

Okay so I rewrote my thesis statement! It’s a wee bit more vague but still a good direction a think. It’s more open so I can talk about more things and add more evidence. Wrote out an in-depth plan and then my brain crapped out. So I’m going to bed! Tomorrow is the day! — 🎃Unpaid Bills🎃 //Chaela (@Cierafire) August 14, 2019

The thesis statement is taught in what’s called the five-paragraph essay (or theme). This essay has an introduction which “funnels into” the thesis statement, including three reasons backing up the main argument. The next three paragraphs develop each of these claims, respectively, citing evidence and examples, such as literary texts, historical documents, or scientific reports. The final paragraph, the conclusion, restates the thesis statement and summarizes the paper and its broader significance.

Even after we are no longer in the classroom, people continue to reference thesis statements. While “real-life” thesis statements may not be as formal as the ones seen in five-paragraph essays, having a thesis statement —a point, a position, or a theory of the case—is considered informative, persuasive, and valuable in work, in the community, and in our personal lives.

The thesis statement is so widely taught and familiar that sometimes people joke about them. On social media, for instance, people may humorously end a post with “In this essay, I will …” when expressing a deeply felt but ultimately low-stakes opinion on some popular topic. The phrase In this essay, I will alludes to the signposting language some people use in their thesis statements.

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

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.

How to write a thesis statement + examples

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 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.

Think of yourself as a member of a jury, listening to a lawyer who is presenting an opening argument. You'll want to know very soon whether the lawyer believes the accused to be guilty or not guilty, and how the lawyer plans to convince you. Readers of academic essays are like jury members: before they have read too far, they want to know what the essay argues as well as how the writer plans to make the argument. After reading your thesis statement, the reader should think, "This essay is going to try to convince me of something. I'm not convinced yet, but I'm interested to see how I might be."

An effective thesis cannot be answered with a simple "yes" or "no." A thesis is not a topic; nor is it a fact; nor is it an opinion. "Reasons for the fall of communism" is a topic. "Communism collapsed in Eastern Europe" is a fact known by educated people. "The fall of communism is the best thing that ever happened in Europe" is an opinion. (Superlatives like "the best" almost always lead to trouble. It's impossible to weigh every "thing" that ever happened in Europe. And what about the fall of Hitler? Couldn't that be "the best thing"?)

A good thesis has two parts. It should tell what you plan to argue, and it should "telegraph" how you plan to argue—that is, what particular support for your claim is going where in your essay.

Steps in Constructing a Thesis

First, analyze your primary sources.  Look for tension, interest, ambiguity, controversy, and/or complication. Does the author contradict himself or herself? Is a point made and later reversed? What are the deeper implications of the author's argument? Figuring out the why to one or more of these questions, or to related questions, will put you on the path to developing a working thesis. (Without the why, you probably have only come up with an observation—that there are, for instance, many different metaphors in such-and-such a poem—which is not a thesis.)

Once you have a working thesis, write it down.  There is nothing as frustrating as hitting on a great idea for a thesis, then forgetting it when you lose concentration. And by writing down your thesis you will be forced to think of it clearly, logically, and concisely. You probably will not be able to write out a final-draft version of your thesis the first time you try, but you'll get yourself on the right track by writing down what you have.

Keep your thesis prominent in your introduction.  A good, standard place for your thesis statement is at the end of an introductory paragraph, especially in shorter (5-15 page) essays. Readers are used to finding theses there, so they automatically pay more attention when they read the last sentence of your introduction. Although this is not required in all academic essays, it is a good rule of thumb.

Anticipate the counterarguments.  Once you have a working thesis, you should think about what might be said against it. This will help you to refine your thesis, and it will also make you think of the arguments that you'll need to refute later on in your essay. (Every argument has a counterargument. If yours doesn't, then it's not an argument—it may be a fact, or an opinion, but it is not an argument.)

This statement is on its way to being a thesis. However, it is too easy to imagine possible counterarguments. For example, a political observer might believe that Dukakis lost because he suffered from a "soft-on-crime" image. If you complicate your thesis by anticipating the counterargument, you'll strengthen your argument, as shown in the sentence below.

Some Caveats and Some Examples

A thesis is never a question.  Readers of academic essays expect to have questions discussed, explored, or even answered. A question ("Why did communism collapse in Eastern Europe?") is not an argument, and without an argument, a thesis is dead in the water.

A thesis is never a list.  "For political, economic, social and cultural reasons, communism collapsed in Eastern Europe" does a good job of "telegraphing" the reader what to expect in the essay—a section about political reasons, a section about economic reasons, a section about social reasons, and a section about cultural reasons. However, political, economic, social and cultural reasons are pretty much the only possible reasons why communism could collapse. This sentence lacks tension and doesn't advance an argument. Everyone knows that politics, economics, and culture are important.

A thesis should never be vague, combative or confrontational.  An ineffective thesis would be, "Communism collapsed in Eastern Europe because communism is evil." This is hard to argue (evil from whose perspective? what does evil mean?) and it is likely to mark you as moralistic and judgmental rather than rational and thorough. It also may spark a defensive reaction from readers sympathetic to communism. If readers strongly disagree with you right off the bat, they may stop reading.

An effective thesis has a definable, arguable claim.  "While cultural forces contributed to the collapse of communism in Eastern Europe, the disintegration of economies played the key role in driving its decline" is an effective thesis sentence that "telegraphs," so that the reader expects the essay to have a section about cultural forces and another about the disintegration of economies. This thesis makes a definite, arguable claim: that the disintegration of economies played a more important role than cultural forces in defeating communism in Eastern Europe. The reader would react to this statement by thinking, "Perhaps what the author says is true, but I am not convinced. I want to read further to see how the author argues this claim."

A thesis should be as clear and specific as possible.  Avoid overused, general terms and abstractions. For example, "Communism collapsed in Eastern Europe because of the ruling elite's inability to address the economic concerns of the people" is more powerful than "Communism collapsed due to societal discontent."

Thesis and Purpose Statements

Use the guidelines below to learn the differences between thesis and purpose statements.

In the first stages of writing, thesis or purpose statements are usually rough or ill-formed and are useful primarily as planning tools.

A thesis statement or purpose statement will emerge as you think and write about a topic. The statement can be restricted or clarified and eventually worked into an introduction.

As you revise your paper, try to phrase your thesis or purpose statement in a precise way so that it matches the content and organization of your paper.

Thesis statements

A thesis statement is a sentence that makes an assertion about a topic and predicts how the topic will be developed. It does not simply announce a topic: it says something about the topic.

Good: X has made a significant impact on the teenage population due to its . . . Bad: In this paper, I will discuss X.

A thesis statement makes a promise to the reader about the scope, purpose, and direction of the paper. It summarizes the conclusions that the writer has reached about the topic.

A thesis statement is generally located near the end of the introduction. Sometimes in a long paper, the thesis will be expressed in several sentences or an entire paragraph.

A thesis statement is focused and specific enough to be proven within the boundaries of the paper. Key words (nouns and verbs) should be specific, accurate, and indicative of the range of research, thrust of the argument or analysis, and the organization of supporting information.

Purpose statements

A purpose statement announces the purpose, scope, and direction of the paper. It tells the reader what to expect in a paper and what the specific focus will be.

Common beginnings include:

“This paper examines . . .,” “The aim of this paper is to . . .,” and “The purpose of this essay is to . . .”

A purpose statement makes a promise to the reader about the development of the argument but does not preview the particular conclusions that the writer has drawn.

A purpose statement usually appears toward the end of the introduction. The purpose statement may be expressed in several sentences or even an entire paragraph.

A purpose statement is specific enough to satisfy the requirements of the assignment. Purpose statements are common in research papers in some academic disciplines, while in other disciplines they are considered too blunt or direct. If you are unsure about using a purpose statement, ask your instructor.

This paper will examine the ecological destruction of the Sahel preceding the drought and the causes of this disintegration of the land. The focus will be on the economic, political, and social relationships which brought about the environmental problems in the Sahel.

Sample purpose and thesis statements

The following example combines a purpose statement and a thesis statement (bold).

The goal of this paper is to examine the effects of Chile’s agrarian reform on the lives of rural peasants. The nature of the topic dictates the use of both a chronological and a comparative analysis of peasant lives at various points during the reform period. . . The Chilean reform example provides evidence that land distribution is an essential component of both the improvement of peasant conditions and the development of a democratic society. More extensive and enduring reforms would likely have allowed Chile the opportunity to further expand these horizons.

Definition of thesis

Did you know.

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

The meaning, history and political rhetoric surrounding the term abortion ‘ban’

Experts say ‘ban’ has emerged as shorthand for nearly all abortion prohibitions. the blunt term often leaves room for political spin..

Ban: Merriam-Webster  defines  it as “a legal or formal prohibition.”

But in the 2024 election cycle — the first general election since Roe v. Wade, the landmark ruling that enshrined a constitutional right to an abortion, was  overturned  — the term has morphed into polarizing political rhetoric. “Ban” has become synonymous with abortion and the wave of anti-abortion laws enacted in states across the country.

For example, on President Joe Biden’s reelection campaign website, the  abortion policy page’s  title reads: “Donald Trump wants to ban abortion nationwide. Re-elect Joe Biden to stop him and protect reproductive freedom.”

Trump appointed three of the U.S. Supreme Court justices who voted to overturn Roe. After years of inconsistency, Trump  most recently  has said that laws on abortion should be left to the states and that he wouldn’t sign a national abortion ban.

Many Democrats and abortion rights activists have also zeroed in on down-ballot Republicans, accusing them of supporting abortion “bans,” even if their position allows for some access.

“Yesterday, we celebrated Mother’s Day. Today, I remind you that politicians like Bernie Moreno, who supports a national abortion ban, don’t want moms making their own healthcare decisions. Abortion rights are on Ohio’s ballot again in 2024,” Ohio Democrat Allison Russo wrote May 13  on X .

Moreno, who has Trump’s support, is a Republican running for Senate in Ohio against Democratic incumbent Sen. Sherrod Brown. Moreno  has said  that he would vote for a 15-week national abortion ban.

Political discourse experts say “ban” has emerged as shorthand for nearly all abortion prohibitions. The blunt term, nuanced in its myriad interpretations, often leaves room for political spin.

What exactly is a ban?

“Ban” is not a medical term; people across the political spectrum on abortion define it differently.

The word has two main rhetorical functions, political discourse experts said. When people talk to like-minded people about a particular issue, it can reinforce the group’s beliefs. Or, it can label opponents as “extreme.”

“For example, when Joe Biden talks about an assault weapon ban, he’s not trying to convert skeptics — he’s signaling to people who already agree with them that they’re on the same team,” said Ryan Skinnell, an associate professor of rhetoric and writing at San Jose State University. “But the other way ‘ban’ works is to identify someone you disagree with as extreme. Groups who want to keep certain books out of libraries, for instance, rarely describe themselves as in support of book banning. Their opponents adopt that language.”

This dual usage reflects in the abortion fight. Abortion-rights activists use “ban” to signal an infringement on personal freedom and autonomy over medical decisions. Anti-abortion proponents may use “ban” to signal a protection of fetal life. For example, when introducing legislation that ban abortion at various stages,  Republican   politicians  have often framed the bills as moral imperatives that protect unborn life.

Peter Loge, a George Washington University professor who directs the school’s Project on Ethics in Political Communication, said ban has historically meant “to eliminate” or “not have,” but politicians employ a strategic ambiguity that allows listeners to assign their own meaning. Loge, who served as a senior adviser in former President Barack Obama’s Food and Drug Administration, said Obama did this with one of his campaign slogans: “Change We Can Believe In.”

“Well, what does ‘change’ mean? Clearly, it means whatever he thinks it means, but as a listener you will ascribe it to mean whatever you think it means,” Loge said. “So, if I think most abortions should be illegal and in some cases it’s OK, I can support a ban, because it’s a ban with exceptions. The listener plugs in whatever caveats they prefer and ascribes them to the speaker. This is a technique as far back as Aristotle, who wrote that the listener provides the reasoning for themselves.”

Loge, like Skinnell, said “ban” is often used in politics to showcase extremism and the threat of something being taken away.

“It’s the rhetoric of anger. ‘They want to take your rights from you. … Now it’s an ideological divide and it works because we’re going to be more motivated to vote,” Loge said. “People are more concerned about losing something they have than they are interested in getting something new. We are risk-averse.”

Nathan Stormer, a rhetoric professor at the University of Maine and an expert in abortion rhetoric, said the term usually shows up when people refer to making abortion illegal in pregnancy’s earlier stages. But, he added, although common usage typically refers to a first trimester threshold, there is “no set of rules.”

“Because it is not a consistently used term, I think when people do not specify what they are referring to, others may take them to mean at conception or very early, but one has to inquire about context,” Stormer wrote in an email.

How abortion ban rhetoric evolved

Before the 1970s, there was little discussion about abortion bans.

Although legal abortion existed in various states at various stages before the  Supreme Court decided Roe v. Wade in 1973,  the ruling’s enshrinement of abortion rights across the country, helped galvanize opposition and mobilize anti-abortion groups.

“There were book bans, pornography bans, dancing bans, and so on. But even most conservative politicians and church groups weren’t especially concerned with abortion as an issue, and there was virtually no concerted political interest in bans,” Skinnell, from San Jose University, said. “That began to change with Richard Nixon.”

Skinnell said the former president’s advisers, in coordination with evangelical Christian church leaders, determined they could connect abortion to left-wing social movements, such as feminism, by linking them consistently in speeches and campaign materials.

“The idea of abortion bans came directly out of that partnership,” Skinnell said, “and it gathered steam in right-wing and conservative circles throughout the next few decades.”

Republicans further popularized the term in the mid-1990s, when they advocated for the Partial-Birth Abortion Ban Act, which President George W. Bush  signed into law  in 2003. The campaign to pass that legislation, experts said, introduced the term “ban” as the abortion restriction’s “stated intent.”

Political rhetoric experts said much of the medical literature and media coverage before Roe v. Wade often used terms such as “illegal” because abortion was considered a criminal act in most states.

“Even in the early stages of criminalizing abortion in the U.S., I don’t think ban was a common term,” Stormer said. “When a restriction is being put in place where before there was not one, people tend to resort to the word ban.”

Emily Winderman, a University of Minnesota professor specializing in the rhetorical study of health and medicine, said that over time abortion “bans” have manifested  as “incremental” restrictions throughout gestational development to the complete prohibitions seen in multiple states today.

For instance, she said, “heartbeat bills,” which typically refer to laws that make abortion illegal as early as six weeks of pregnancy, were controversial when they emerged around 2010, but have become more prevalent since the Trump administration and Roe’s overturning.

Winderman also said bans can appear via code and ordinance restrictions, such as banning  the type of use for a particular piece of real estate — making abortion clinics impossible to place.

“It’s important to understand bans as a complex strategy that includes gestational limits as well as limitations on who can provide care and where,” she said.

Shifting abortion laws across the U.S. have made “ban” an increasingly common term.  Forty-one states  now ban abortion at different points in pregnancy — 14 enforce total bans, three enforce six-week bans and others restrict abortion before fetal viability.

Stormer, from the University of Maine, pointed to Arizona’s Supreme Court reinstating an 1864 law that completely banned abortion. (It  has since been repealed. ) At the time the law was written, conception was not well understood, and there was no clear sense of fertilization or how it worked.

“Reinstating that law was a great example of how the conflict over abortion has remained steady and largely recognizable, but its terms and understandings have been constantly moving, which says something,” Stormer said. “So, specific words do important work, but they do not capture what is happening rhetorically, in my opinion. The moving terminologies are the waves crashing, but the tides are the thing.”

FACT SHEET: President   Biden Takes Action to Protect American Workers and Businesses from China’s Unfair Trade   Practices

President Biden’s economic plan is supporting investments and creating good jobs in key sectors that are vital for America’s economic future and national security. China’s unfair trade practices concerning technology transfer, intellectual property, and innovation are threatening American businesses and workers. China is also flooding global markets with artificially low-priced exports. In response to China’s unfair trade practices and to counteract the resulting harms, today, President Biden is directing his Trade Representative to increase tariffs under Section 301 of the Trade Act of 1974 on $18 billion of imports from China to protect American workers and businesses.   The Biden-Harris Administration’s Investing in America agenda has already catalyzed more than $860 billion in business investments through smart, public incentives in industries of the future like electric vehicles (EVs), clean energy, and semiconductors. With support from the Bipartisan Infrastructure Law, CHIPS and Science Act, and Inflation Reduction Act, these investments are creating new American jobs in manufacturing and clean energy and helping communities that have been left behind make a comeback.   As President Biden says, American workers and businesses can outcompete anyone—as long as they have fair competition. But for too long, China’s government has used unfair, non-market practices. China’s forced technology transfers and intellectual property theft have contributed to its control of 70, 80, and even 90 percent of global production for the critical inputs necessary for our technologies, infrastructure, energy, and health care—creating unacceptable risks to America’s supply chains and economic security. Furthermore, these same non-market policies and practices contribute to China’s growing overcapacity and export surges that threaten to significantly harm American workers, businesses, and communities.   Today’s actions to counter China’s unfair trade practices are carefully targeted at strategic sectors—the same sectors where the United States is making historic investments under President Biden to create and sustain good-paying jobs—unlike recent proposals by Congressional Republicans that would threaten jobs and raise costs across the board. The previous administration’s trade deal with China  failed  to increase American exports or boost American manufacturing as it had promised. Under President Biden’s Investing in America agenda, nearly 800,000 manufacturing jobs have been created and new factory construction has doubled after both fell under the previous administration, and the trade deficit with China is the lowest in a decade—lower than any year under the last administration.   We will continue to work with our partners around the world to strengthen cooperation to address shared concerns about China’s unfair practices—rather than undermining our alliances or applying indiscriminate 10 percent tariffs that raise prices on all imports from all countries, regardless whether they are engaged in unfair trade. The Biden-Harris Administration recognizes the benefits for our workers and businesses from strong alliances and a rules-based international trade system based on fair competition.   Following an in-depth review by the United States Trade Representative, President Biden is taking action to protect American workers and American companies from China’s unfair trade practices. To encourage China to eliminate its unfair trade practices regarding technology transfer, intellectual property, and innovation, the President is directing increases in tariffs across strategic sectors such as steel and aluminum, semiconductors, electric vehicles, batteries, critical minerals, solar cells, ship-to-shore cranes, and medical products.   Steel and Aluminum   The tariff rate on certain steel and aluminum products under Section 301 will increase from 0–7.5% to 25% in 2024.   Steel is a vital sector for the American economy, and American companies are leading the future of clean steel. Recently, the Biden-Harris Administration announced $6 billion for 33 clean manufacturing projects including for steel and aluminum, including the first new primary aluminum smelter in four decades, made possible by the Bipartisan Infrastructure Law and the Inflation Reduction Act. These investments will make the United States one of the first nations in the world to convert clean hydrogen into clean steel, bolstering the U.S. steel industry’s competitiveness as the world’s cleanest major steel producer.   American workers continue to face unfair competition from China’s non-market overcapacity in steel and aluminum, which are among the world’s most carbon intensive. China’s policies and subsidies for their domestic steel and aluminum industries mean high-quality, low-emissions U.S. products are undercut by artificially low-priced Chinese alternatives produced with higher emissions. Today’s actions will shield the U.S. steel and aluminum industries from China’s unfair trade practices.   Semiconductors   The tariff rate on semiconductors will increase from 25% to 50% by 2025.   China’s policies in the legacy semiconductor sector have led to growing market share and rapid capacity expansion that risks driving out investment by market-driven firms. Over the next three to five years, China is expected to account for almost half of all new capacity coming online to manufacture certain legacy semiconductor wafers. During the pandemic, disruptions to the supply chain, including legacy chips, led to price spikes in a wide variety of products, including automobiles, consumer appliances, and medical devices, underscoring the risks of overreliance on a few markets.   Through the CHIPS and Science Act, President Biden is making a nearly $53 billion investment in American semiconductor manufacturing capacity, research, innovation, and workforce. This will help counteract decades of disinvestment and offshoring that has reduced the United States’ capacity to manufacture semiconductors domestically. The CHIPS and Science Act includes $39 billion in direct incentives to build, modernize, and expand semiconductor manufacturing fabrication facilities as well as a 25% investment tax credit for semiconductor companies. Raising the tariff rate on semiconductors is an important initial step to promote the sustainability of these investments.   Electric Vehicles (EVs)   The tariff rate on electric vehicles under Section 301 will increase from 25% to 100% in 2024.   With extensive subsidies and non-market practices leading to substantial risks of overcapacity, China’s exports of EVs grew by 70% from 2022 to 2023—jeopardizing productive investments elsewhere. A 100% tariff rate on EVs will protect American manufacturers from China’s unfair trade practices.   This action advances President Biden’s vision of ensuring the future of the auto industry will be made in America by American workers. As part of the President’s Investing in America agenda, the Administration is incentivizing the development of a robust EV market through business tax credits for manufacturing of batteries and production of critical minerals, consumer tax credits for EV adoption, smart standards, federal investments in EV charging infrastructure, and grants to supply EV and battery manufacturing. The increase in the tariff rate on electric vehicles will protect these investments and jobs from unfairly priced Chinese imports.   Batteries, Battery Components and Parts, and Critical Minerals   The tariff rate on lithium-ion EV batteries will increase from 7.5%% to 25% in 2024, while the tariff rate on lithium-ion non-EV batteries will increase from 7.5% to 25% in 2026. The tariff rate on battery parts will increase from 7.5% to 25% in 2024.   The tariff rate on natural graphite and permanent magnets will increase from zero to 25% in 2026. The tariff rate for certain other critical minerals will increase from zero to 25% in 2024.   Despite rapid and recent progress in U.S. onshoring, China currently controls over 80 percent of certain segments of the EV battery supply chain, particularly upstream nodes such as critical minerals mining, processing, and refining. Concentration of critical minerals mining and refining capacity in China leaves our supply chains vulnerable and our national security and clean energy goals at risk. In order to improve U.S. and global resiliency in these supply chains, President Biden has invested across the U.S. battery supply chain to build a sufficient domestic industrial base. Through the Bipartisan Infrastructure Law, the Defense Production Act, and the Inflation Reduction Act, the Biden-Harris Administration has invested nearly $20 billion in grants and loans to expand domestic production capacity of advanced batteries and battery materials. The Inflation Reduction Act also contains manufacturing tax credits to incentivize investment in battery and battery material production in the United States. The President has also established the American Battery Materials Initiative, which will mobilize an all-of-government approach to secure a dependable, robust supply chain for batteries and their inputs.   Solar Cells   The tariff rate on solar cells (whether or not assembled into modules) will increase from 25% to 50% in 2024.   The tariff increase will protect against China’s policy-driven overcapacity that depresses prices and inhibits the development of solar capacity outside of China. China has used unfair practices to dominate upwards of 80 to 90% of certain parts of the global solar supply chain, and is trying to maintain that status quo. Chinese policies and nonmarket practices are flooding global markets with artificially cheap solar modules and panels, undermining investment in solar manufacturing outside of China.   The Biden-Harris Administration has made historic investments in the U.S. solar supply chain, building on early U.S. government-enabled research and development that helped create solar cell technologies. The Inflation Reduction Act provides supply-side tax incentives for solar components, including polysilicon, wafers, cells, modules, and backsheet material, as well as tax credits and grant and loan programs supporting deployment of utility-scale and residential solar energy projects. As a result of President Biden’s Investing in America agenda, solar manufacturers have already announced nearly $17 billion in planned investment under his Administration—an 8-fold increase in U.S. manufacturing capacity, enough to supply panels for millions of homes each year by 2030.   Ship-to-Shore Cranes   The tariff rate on ship-to-shore cranes will increase from 0% to 25% in 2024.   The Administration continues to deliver for the American people by rebuilding the United States’ industrial capacity to produce port cranes with trusted partners. A 25% tariff rate on ship-to-shore cranes will help protect U.S. manufacturers from China’s unfair trade practices that have led to excessive concentration in the market. Port cranes are essential pieces of infrastructure that enable the continuous movement and flow of critical goods to, from, and within the United States, and the Administration is taking action to mitigate risks that could disrupt American supply chains. This action also builds off of ongoing work to invest in U.S. port infrastructure through the President’s Investing in America Agenda. This port security initiative includes bringing port crane manufacturing capabilities back to the United States to support U.S. supply chain security and encourages ports across the country and around the world to use trusted vendors when sourcing cranes or other heavy equipment.   Medical Products   The tariff rates on syringes and needles will increase from 0% to 50% in 2024. For certain personal protective equipment (PPE), including certain respirators and face masks, the tariff rates will increase from 0–7.5% to 25% in 2024. Tariffs on rubber medical and surgical gloves will increase from 7.5% to 25% in 2026.   These tariff rate increases will help support and sustain a strong domestic industrial base for medical supplies that were essential to the COVID-19 pandemic response, and continue to be used daily in every hospital across the country to deliver essential care. The federal government and the private sector have made substantial investments to build domestic manufacturing for these and other medical products to ensure American health care workers and patients have access to critical medical products when they need them. American businesses are now struggling to compete with underpriced Chinese-made supplies dumped on the market, sometimes of such poor quality that they may raise safety concerns for health care workers and patients.   Today’s announcement reflects President Biden’s commitment to always have the back of American workers. When faced with anticompetitive, unfair practices from abroad, the President will deploy any and all tools necessary to protect American workers and industry.

70 years after brown v. board of education, new research shows rise in school segregation.

As the nation prepares to mark the 70th anniversary of the landmark U.S. Supreme Court ruling in Brown v. Board of Education , a new report from researchers at Stanford and USC shows that racial and economic segregation among schools has grown steadily in large school districts over the past three decades — an increase that appears to be driven in part by policies favoring school choice over integration.

Analyzing data from U.S. public schools going back to 1967, the researchers found that segregation between white and Black students has increased by 64 percent since 1988 in the 100 largest districts, and segregation by economic status has increased by about 50 percent since 1991.

The report also provides new evidence about the forces driving recent trends in school segregation, showing that the expansion of charter schools has played a major role.  

The findings were released on May 6 with the launch of the Segregation Explorer , a new interactive website from the Educational Opportunity Project at Stanford University. The website provides searchable data on racial and economic school segregation in U.S. states, counties, metropolitan areas, and school districts from 1991 to 2022. 

“School segregation levels are not at pre- Brown levels, but they are high and have been rising steadily since the late 1980s,” said Sean Reardon , the Professor of Poverty and Inequality in Education at Stanford Graduate School of Education and faculty director of the Educational Opportunity Project. “In most large districts, school segregation has increased while residential segregation and racial economic inequality have declined, and our findings indicate that policy choices – not demographic changes – are driving the increase.” 

“There’s a tendency to attribute segregation in schools to segregation in neighborhoods,” said Ann Owens , a professor of sociology and public policy at USC. “But we’re finding that the story is more complicated than that.”

Assessing the rise

In the Brown v. Board decision issued on May 17, 1954, the U.S. Supreme Court ruled that racially segregated public schools violated the Equal Protection Clause of the Fourteenth Amendment and established that “separate but equal” schools were not only inherently unequal but unconstitutional. The ruling paved the way for future decisions that led to rapid school desegregation in many school districts in the late 1960s and early 1970s.

Though segregation in most school districts is much lower than it was 60 years ago, the researchers found that over the past three decades, both racial and economic segregation in large districts increased. Much of the increase in economic segregation since 1991, measured by segregation between students eligible and ineligible for free lunch, occurred in the last 15 years.

White-Hispanic and white-Asian segregation, while lower on average than white-Black segregation, have both more than doubled in large school districts since the 1980s. 

Racial-economic segregation – specifically the difference in the proportion of free-lunch-eligible students between the average white and Black or Hispanic student’s schools – has increased by 70 percent since 1991. 

School segregation is strongly associated with achievement gaps between racial and ethnic groups, especially the rate at which achievement gaps widen during school, the researchers said.  

“Segregation appears to shape educational outcomes because it concentrates Black and Hispanic students in higher-poverty schools, which results in unequal learning opportunities,” said Reardon, who is also a senior fellow at the Stanford Institute for Economic Policy Research and a faculty affiliate of the Stanford Accelerator for Learning . 

Policies shaping recent trends 

The recent rise in school segregation appears to be the direct result of educational policy and legal decisions, the researchers said. 

Both residential segregation and racial disparities in income declined between 1990 and 2020 in most large school districts. “Had nothing else changed, that trend would have led to lower school segregation,” said Owens. 

But since 1991, roughly two-thirds of districts that were under court-ordered desegregation have been released from court oversight. Meanwhile, since 1998, the charter sector – a form of expanded school choice – has grown.

Expanding school choice could influence segregation levels in different ways: If families sought schools that were more diverse than the ones available in their neighborhood, it could reduce segregation. But the researchers found that in districts where the charter sector expanded most rapidly in the 2000s and 2010s, segregation grew the most. 

The researchers’ analysis also quantified the extent to which the release from court orders accounted for the rise in school segregation. They found that, together, the release from court oversight and the expansion of choice accounted entirely for the rise in school segregation from 2000 to 2019.

The researchers noted enrollment policies that school districts can implement to mitigate segregation, such as voluntary integration programs, socioeconomic-based student assignment policies, and school choice policies that affirmatively promote integration. 

“School segregation levels are high, troubling, and rising in large districts,” said Reardon. “These findings should sound an alarm for educators and policymakers.”

Additional collaborators on the project include Demetra Kalogrides, Thalia Tom, and Heewon Jang. This research, including the development of the Segregation Explorer data and website, was supported by the Russell Sage Foundation, the Robert Wood Johnson Foundation, and the Bill and Melinda Gates Foundation.

NASA’s Juno Provides High-Definition Views of Europa’s Icy Shell

Jupiter’s moon Europa was captured by the JunoCam instrument aboard NASA’s Juno spacecraft during the mission’s close flyby on Sept. 29, 2022. The images show the fractures, ridges, and bands that crisscross the moon’s surface.

Imagery from the solar-powered spacecraft shows some intriguing features on the ice-encased Jovian moon.

Images from the JunoCam visible-light camera aboard NASA’s Juno spacecraft supports the theory that the icy crust at the north and south poles of Jupiter’s moon Europa is not where it used to be. Another high-resolution picture of the icy moon, by the spacecraft’s Stellar Reference Unit (SRU), reveals signs of possible plume activity and an area of ice shell disruption where brine may have recently bubbled to the surface.

The JunoCam results recently appeared in the Planetary Science Journal and the SRU results in the journal JGR Planets .

On Sept. 29, 2022, Juno made its closest flyby of Europa , coming within 220 miles (355 kilometers) of the moon’s frozen surface. The four pictures taken by JunoCam and one by the SRU are the first high-resolution images of Europa since Galileo’s last flyby in 2000.

True Polar Wander

Juno’s ground track over Europa allowed imaging near the moon’s equator. When analyzing the data, the JunoCam team found that along with the expected ice blocks, walls, scarps, ridges, and troughs, the camera also captured irregularly distributed steep-walled depressions 12 to 31 miles (20 to 50 kilometers) wide. They resemble large ovoid pits previously found in imagery from other locations of Europa.

This black-and-white image of Europa’s surface was taken by the Stellar Reference Unit (SRU) aboard NASA’s Juno spacecraft during the Sept. 29, 2022, flyby. The chaos feature nicknamed “the Platypus” is seen in the lower right corner.

This annotated image of Europa’s surface from Juno’s SRU shows the location of a double ridge running east-west (blue box) with possible plume stains and the chaos feature the team calls “the Platypus” (orange box). These features hint at current surface activity and the presence of subsurface liquid water on the icy Jovian moon.

A giant ocean is thought to reside below Europa’s icy exterior, and these surface features have been associated with “ true polar wander ,” a theory that Europa’s outer ice shell is essentially free-floating and moves.

“True polar wander occurs if Europa’s icy shell is decoupled from its rocky interior, resulting in high stress levels on the shell, which lead to predictable fracture patterns,” said Candy Hansen, a Juno co-investigator who leads planning for JunoCam at the Planetary Science Institute in Tucson, Arizona. “This is the first time that these fracture patterns have been mapped in the southern hemisphere, suggesting that true polar wander’s effect on Europa’s surface geology is more extensive than previously identified.”

Need Some Space?

The high-resolution JunoCam imagery has also been used to reclassify a formerly prominent surface feature from the Europa map.

“Crater Gwern is no more,” said Hansen. “What was once thought to be a 13-mile-wide impact crater — one of Europa’s few documented impact craters — Gwern was revealed in JunoCam data to be a set of intersecting ridges that created an oval shadow.”

The Platypus

Although all five Europa images from Juno are high-resolution, the image from the spacecraft’s black-and-white SRU offers the most detail. Designed to detect dim stars for navigation purposes, the SRU is sensitive to low light. To avoid over-illumination in the image, the team used the camera to snap the nightside of Europa while it was lit only by sunlight scattered off Jupiter (a phenomenon called “Jupiter-shine”).

This innovative approach to imaging allowed complex surface features to stand out, revealing intricate networks of cross-cutting ridges and dark stains from potential plumes of water vapor. One intriguing feature, which covers an area 23 miles by 42 miles (37 kilometers by 67 kilometers), was nicknamed by the team “the Platypus” because of its shape.

Characterized by chaotic terrain with hummocks, prominent ridges, and dark reddish-brown material, the Platypus is the youngest feature in its neighborhood. Its northern “torso” and southern “bill” — connected by a fractured “neck” formation — interrupt the surrounding terrain with a lumpy matrix material containing numerous ice blocks that are 0.6 to 4.3 miles (1 to 7 kilometers) wide. Ridge formations collapse into the feature at the edges of the Platypus.

For the Juno team, these formations support the idea that Europa’s ice shell may give way in locations where pockets of briny water from the subsurface ocean are present beneath the surface.

About 31 miles (50 kilometers) north of the Platypus is a set of double ridges flanked by dark stains similar to features found elsewhere on Europa that scientists have hypothesized to be cryovolcanic plume deposits.

“These features hint at present-day surface activity and the presence of subsurface liquid water on Europa,” said Heidi Becker, lead co-investigator for the SRU at NASA’s Jet Propulsion Laboratory in Southern California, which also manages the mission. “The SRU’s image is a high-quality baseline for specific places NASA’s Europa Clipper mission and ESA’s (European Space Agency’s) Juice missions can target to search for signs of change and brine.”

Europa Clipper ’s focus is on Europa — including investigating whether the icy moon could have conditions suitable for life. It is scheduled to launch on the fall of 2024 and arrive at Jupiter in 2030. Juice (Jupiter Icy Moons Explorer) launched on April 14, 2023. The ESA mission will reach Jupiter in July 2031 to study many targets (Jupiter’s three large icy moons, as well as fiery Io and smaller moons, along with the planet’s atmosphere, magnetosphere, and rings) with a special focus on Ganymede.

Juno executed its 61st close flyby of Jupiter on May 12. Its 62nd flyby of the gas giant, scheduled for June 13, includes an Io flyby at an altitude of about 18,200 miles (29,300 kilometers).

Why Donald Trump ended up praising Hollywood’s most famous cannibal

During an angry speech in New Jersey, Trump allowed his exaggerations to overflow.

When Donald Trump is not reading the teleprompter, it’s hard to know what you’re going to get. Perhaps you’ll get the standard angry riffs about the things Trump has been saying he is angry about for the past nine years. Perhaps you’ll get an anecdote about how a big, strong man came up to Trump, tears in his eyes, and thanked the former president — “Sir, thank you!” — for what he did on whatever issue Trump had just talked about.

Or perhaps, as was the case in New Jersey this weekend, you’ll get a bit of praise for the murderous cannibal from the movie “Silence of the Lambs.”

“The late, great Hannibal Lecter is a wonderful man,” Trump said — a sentence that has, it seems safe to assume, never before been uttered by a current or former American president. He prefaced this comment by asking whether anyone had seen the aforementioned movie. It would be safe to assume that perhaps Trump hadn’t, given his description of Lecter as “wonderful,” except that he then made reference to the final scene in the film, in which Lecter is about to murder someone. After mentioning that scene, Trump for some reason offered Lecter his congratulations.

One might justifiably wonder how this subject came up and why. The answer is uncomplicated in the way that Trump’s “sir” stories are.

Trump had just finished describing President Biden as a moron, worse than the 10 worst presidents in U.S. history combined.

“We’re supposed to cherish the office of president,” Trump said. “You don’t do what he did to try and win votes” — that is, serve as president as your predecessor racks up criminal indictments. (Trump frames this as proactive targeting by Biden, of course, but it isn’t.) Then Trump pivoted to his need to win back the White House in November.

“The biggest thing we have is we have millions of people here that are criminals,” he said. “We really — I mean, they’re criminals.”

“Send them back!” someone in the crowd shouted.

“Think of it: Venezuela just announced — and they had a new number was 67 now it’s 72 percent — 72 percent they’re down in crime because they took their gangs, their gang members, they took a lot of their criminals and they moved them into the United States of America,” Trump continued. “Jail populations all over the world are way down and these” — Trump searched for the best word for a moment — “ fools back there, the press, the fake news — they don’t want to report it.”

“You know why they’re down?” he continued. “Because they’re sending people in their jails into the United States. From Africa, from Asia, from all over the world. They’re emptying out their jails into the United States.”

The media isn’t reporting that crime in Venezuela is down 72 percent or that countries are emptying their jails into the United States because those things are not true, and we, unlike candidates for the presidency, are duty-bound to present information accurately.

The Venezuela thing was assessed by PolitiFact. The drop in crime was far smaller than Trump suggests because of several factors, including that the poor economy leaves less opportunity for criminals. There is no evidence that the government is sending criminals to the United States, and, in fact, most migration out of Venezuela is to nearby countries.

The idea that other countries, like those in Africa and Asia, are sending prison populations to the United States is more obviously baseless. How does that work, exactly? Not rhetorically, obviously; it’s clear how warnings about non-White people from exotic places are meant to land with the audience. But practically. Streams of 737s taking off from Lagos and landing in Tijuana?

It’s just an exaggeration, pushing the rhetoric further and further. If you accept that the media is lying to you and that there is evidence that Venezuela is shipping people north, then why not take it further? Why not believe, say, that China is building an army inside the United States?

Trump’s exaggerations had not yet peaked, of course.

“They’re emptying out their mental institutions into the United States, our beautiful country,” he continued. “And now the prison populations all over the world are down. They don’t want to report that. The mental institution population is down because they’re taking people from insane asylums and from mental institution — you know what the difference is, right? An insane asylum is a mental institution on steroids.”

Well, the difference really is that the former sounds scarier and more pejorative than the latter, so it has fallen out of favor. But scarier and pejorative is exactly what Trump is going for. And what better way to do that than to remind people of perhaps the scariest resident of a mental institution in American popular culture?

“‘Silence of the Lamb,’” Trump said. “Has anyone ever seen ‘The Silence of the Lambs’?”

And here we go.

“The late, great Hannibal Lecter is a wonderful man,” Trump continued. “He oftentimes would have a friend for dinner. Remember the last scene? ‘Excuse me, I’m about to have a friend for dinner’ as this poor doctor walked by. ‘I’m about to have a friend for dinner.’ But Hannibal Lecter, congratulations. The late, great Hannibal Lecter.”

And that was it. This was all off teleprompter, mind you, so there was no careful tying of the story back to the purported immigrant threat or to some evidence that, say, Thailand had sent the residents of a mental hospital to some swing state. Just a little riff on how scary this one guy from a movie is.

But Trump did put a fine point on the anecdote in the abstract.

“We have people that are being released into our country that we don’t want in our country,” Trump said, again using the baseless verb “released” to imply that it was part of some intentional effort. “And they’re coming in totally unchecked, totally unvetted, and we can’t let this happen. They’re just destroying our country.”

Once again, from the crowd: “Send them back!”

“And we’re sitting back,” Trump continued, “and we better damn well win this election ’cause if we don’t, our country is going to be doomed. It’s going to be doomed.”

It’s all apocalypticism. Everything is a slippery slope, and we’re all nearly at the bottom, all the time, in all ways. This is and has long been Trump’s pitch to voters, either that the United States is doomed because of the current president or (as was offered in 2020) that the collapse will occur imminently should he lose his position. The nuance comes only from how far Trump is willing to take it.

Praising Hannibal Lecter’s cannibalism is further than usual.

Election 2024

Get the latest news on the 2024 election from our reporters on the campaign trail and in Washington.

Who is running? President Biden and Donald Trump secured their parties’ nominations for the presidency . Here’s how we ended up with a Trump-Biden rematch again.

Key dates and events: From January to June, voters in all states and U.S. territories will pick their party’s nominee for president ahead of the summer conventions. Here are key dates and events on the 2024 election calendar .

Abortion and the election: Voters in about a dozen states could decide the fate of abortion rights with constitutional amendments on the ballot in a pivotal election year. Biden supports legal access to abortion , and he has encouraged Congress to pass a law that would codify abortion rights nationwide. After months of mixed signals about his position, Trump said the issue should be left to states . Here’s how Biden’s and Trump’s abortion stances have shifted over the years.
