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.

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

  • tells the reader how you will interpret the significance of the subject matter under discussion.
  • is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
  • directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
  • makes a claim that others might dispute.
  • is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

  • Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
  • Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
  • Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
  • Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
  • Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
  • Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

  • Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
  • Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
  • Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
  • Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
  • Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

  • Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.
  • Do I answer the question? Yes!
  • Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
  • Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
  • Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
  • Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

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.

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?

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

purpose of the thesis statements

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.

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.

Thesis Statements

A thesis statement is a sentence (sometimes more than one sentence) in the introduction that tells the reader the following information:

  • What the topic of the paper is
  • How the writer intends to discuss that topic
  •  It gives a blueprint for how the essay will be structured
  •  How the writer intends to prove or demonstrate his or her main points.

Think of your paper as a human body, and your thesis statement as the spinal cord. Without it, there is no structure.

For you as the writer, the thesis statement:

Develops through the interrelationship of thinking, reading, and writing;

Limits your research by providing you with one controlling main idea that intrigues you;

Narrows your writing to one specific claim that you can develop or prove;

Organizes your ideas so you know the important points you want to make in your paper; and

Clarifies your writing by keeping you on target to fulfill your proposed purpose.

For your readers, the thesis statement:

 Identifies the main point and sub-points of your essay clearly and quickly;

Functions as a road map so your readers can easily follow your ideas; and

Gives satisfaction at the conclusion of the paper when your readers discover you have fulfilled your promise by proving or developing your main point.

Characteristics of Effective Thesis Statements

An effective thesis statement must be  factual and narrow.

An effective thesis statement prepares readers for facts and details, but it cannot itself be a fact. It must always be an inference that demands proof or further development. These proofs come from the literature. 

UNT Dallas campus has two buildings.

Not factual enough: The UNT Dallas campus is the perfect size.

Just Right:  While some might see small universities as a disadvantage, the small campus of UNT Dallas holds many advantages for students, including a close-knit campus community, smaller class sizes, and better support from professors.

2. Narrow Topic

A good thesis should be narrow, and not too broad or too vague. If the topic is too broad, you won’t be able to cover the entire topic in your paper.  If it’s too narrow, you might not be able to find research, and your paper probably won’t be long enough. 

Too Broad: College students have a lot of responsibilities.

Too Narrow: Student workers in the Learning Commons at UNT Dallas have many responsibilities in their course work and tutoring. 

Just Right: College students who are financially independent have many responsibilities as they must maintain good grades, pay living expenses, and balance work and school.

Remember, a thesis statement is not: 

  • Instead , you should argue, based on facts and literature, why or why not NASA should receive more funding.  
  • Ask yourself--can I find anything in literature to prove this point, or is this MY opinion? 
  • Instead, you should argue why or why not people like chocolate OR why or why not chocolate is healthy for you based on facts and literature findings. 
  • Similar to the subjective opinion, ask yourself is this statement is based on facts and literature findings or if this is YOUR opinion. Although it is ok to have your own opinion, professors usually do not like to read articles about beliefs (students have been writing about these for years and years). 
  • Instead, you could discuss theories about politics or religions and use literature to prove or disprove those theories.
  • This is too factual (the Himalayas WERE formed from a collision of tectonic plates), and there is nothing to discuss because this IS a fact in itself. 
  • Instead, you could compare and contrast the tectonic plate formation of different mountains. 

Examples of Thesis Statements

A thesis statement f or a 5 paragraph essay conta ins three parts:.

1. A Topic: the main idea of the essay

2. The Controlling Idea: what you want to say about the topic

3. The subtopics: usually 3 examples/reasons you will discuss in your paper

Here is an example  of a thesis statement.

Ex: Regularly visiting the Writing Center at UNT Dallas will help you become the best writer on the planet because it offers superhero tutors, current technology, and fantastic handouts.

The main topic explores the idea that regularly vsiting the writing center will help you become the best writer on the planet, and the subtopics further expand this opinion with three distinct examples: 1) tutors, 2) technology, and 3) the handouts.

Outline Example

The paper should be organized around the subtopics.  For example, for the thesis written above, the writer would write one body paragraph about the tutors, one about technology, and one about the handouts. 

Here is a sample essay outline based on this thesis:

  • Introduce the topic of tutoring
  • Thesis (last sentence of intro): Regularly visiting the Writing Center at UNT Dallas will help you become the best writer on the planet because it offers superhero tutors, current technology, and fantastic handouts.
  • topic sentence
  • Restate thesis
  • Concluding remarks

For further assistance with the structure, see our handouts on Introductions and Conclusions and Topic Sentences.

A thesis statement for a LONG ESSAY contains two parts: A Topic: the main idea of the essay The Controlling Idea: what you want to say about the topic 

Throughout the paper, your thesis promises your readers that you will prove specific facts or develop certain ideas ; therefore, every paragraph, sentence, and word in your paper must relate to this controlling idea.

Here are some examples of thesis statements.

  • Baseball, once a national pastime and even an addiction, has lost its popularity because of the new interest in more violent sports.
  • Since the space program has yet to provide the American people with any substantial, practical returns, it is a waste of money and should be dissolved.
  • To stop the alarming rise in the number of violent crimes committed every year, our courts must hand out tougher sentences.
  • Detective stories appeal to the basic human desire for thrills.
  • Hemingway's war stories helped to create a new prose style.
  • Bronte utilizes light and fire to symbolize the emotional expressions of the characters.

Here is a suggested outline for a long essay and how that would look in terms of your thesis statement, topic, and controlling ideas:

  • Introduce the novel Jane Eyre and the topic of symbolism
  • Thesis (last sentence of intro): Bronte utilizes light and fire to symbolize the emotional expressions of the characters.
  • textual examples and elaboration

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.

2.5 Writing Thesis Statements

Kathryn Crowther; Lauren Curtright; Nancy Gilbert; Barbara Hall; Tracienne Ravita; and Kirk Swenson

To be effective, all support in an essay must work together to convey a central point; otherwise, an essay can fall into the trap of being out of order and confusing. Just as a topic sentence focuses and unifies a single paragraph, the thesis statement focuses and unifies an entire essay. This statement is like a signpost that signals the essay’s destination; it tells the reader the point you want to make in your essay, while the essay itself supports that point.

Because writing is not a linear process, you may find that the best thesis statement develops near the end of your first draft. However, creating a draft or working thesis early in the writing project helps give the drafting process clear direction. You should form your thesis before you begin to organize an essay, but you may find that it needs revision as the essay develops.

A thesis is not just a topic, but rather the writer’s comment or interpretation of the question or subject. For whatever topic you select (for example, school uniforms, social networking), you must ask yourself, “What do I want to say about it?” Asking and then answering this question is vital to forming a thesis that is precise, forceful, and confident.

In the majority of essays, a thesis is one sentence long and appears toward the end of the introductory paragraph. It is specific and focuses on one to three points of a single idea—points that are able to be demonstrated in the body paragraphs. It forecasts the content of the essay and suggests how you will organize your information. Remember that a thesis statement does not summarize an issue but rather dissects it.

Working Thesis Statements

A strong thesis statement must have the following qualities:

  • It must be arguable.  A thesis statement must state a point of view or judgment about a topic. An established fact is not considered arguable.
  • It must be supportable.  The thesis statement must contain a point of view that can be supported with evidence (reasons, facts, examples).
  • It must be specific. A thesis statement must be precise enough to allow for a coherent argument and remain focused on the topic.

Examples of Appropriate Thesis Statements

  • Closing all American borders for a period of five years is one solution that will tackle illegal immigration.
  • Compared to an absolute divorce, no-fault divorce is less expensive, promotes fairer settlements, and reflects a more realistic view of the causes for marital breakdown.
  • Exposing children from an early age to the dangers of drug abuse is a sure method of preventing future drug addicts.
  • In today’s crumbling job market, a high school diploma is not significant enough education to land a stable, lucrative job.
  • The societal and personal struggles of Troy Maxson in the play Fences symbolize the challenges of black males who lived through segregation and integration in the United States.

Pitfalls to Avoid

A thesis is weak when it is simply a declaration of your subject or a description of what you will discuss in your essay.

Weak Thesis Statement Example

My paper will explain why imagination is more important than knowledge.

A thesis is weak when it makes an unreasonable or outrageous claim or insults the opposing side.

Religious radicals across America are trying to legislate their Puritanical beliefs by banning required high school books.

A thesis is weak when it contains an obvious fact or something that no one can disagree with or provides a dead end.

Advertising companies use sex to sell their products.

A thesis is weak when the statement is too broad.

The life of Abraham Lincoln was long and challenging.

Ways to Revise Your Thesis

Your thesis statement begins as a working thesis statement, an indefinite statement that you make about your topic early in the writing process for the purpose of planning and guiding your writing. Working thesis statements often become stronger as you gather information and develop new ideas and reasons for those ideas. Revision helps you strengthen your thesis so that it matches what you have expressed in the body of the paper.

You can cut down on irrelevant aspects and revise your thesis by taking the following steps:

  • Pinpoint and replace all non specific words, such as people, everything, society, or life, with more precise words in order to reduce any vagueness.

Pinpoint and Replace Example

Working thesis:  Young people have to work hard to succeed in life.

Revised thesis:  Recent college graduates must have discipline and persistence in order to find and maintain a stable job in which they can use, and be appreciated for, their talents.

Explanation:  The original includes too broad a range of people and does not define exactly what success entails. By replacing those general words like people and work hard , the writer can better focus their research and gain more direction in their writing. The revised thesis makes a more specific statement about success and what it means to work hard.

  • Clarify ideas that need explanation by asking yourself questions that narrow your thesis.

Clarify Example

Working thesis:  The welfare system is a joke.

Revised thesis:  The welfare system keeps a socioeconomic class from gaining employment by alluring members of that class with unearned income, instead of programs to improve their education and skill sets.

Explanation:  A joke means many things to many people. Readers bring all sorts of backgrounds and perspectives to the reading process and would need clarification for a word so vague. This expression may also be too informal for the selected audience. By asking questions, the writer can devise a more precise and appropriate explanation for joke and more accurately defines their stance, which will better guide the writing of the essay.

  • Replace any linking verbs with action verbs. Linking verbs are forms of the verb to be , a verb that simply states that a situation exists.

Replace with Action Verbs Example

Working thesis:  Kansas City school teachers are not paid enough.

Revised thesis:  The Kansas City legislature cannot afford to pay its educators, resulting in job cuts and resignations in a district that sorely needs highly qualified and dedicated teachers.

Explanation:  The linking verb in this working thesis statement is the word are . Linking verbs often make thesis statements weak because they do not express action. Rather, they connect words and phrases to the second half of the sentence. Readers might wonder, “Why are they not paid enough?” But this statement does not compel them to ask many more questions.

  • Who is not paying the teachers enough?
  • How much is considered “enough”?
  • What is the problem?
  • What are the results?
  • Omit any general claims that are hard to support.

Omit General Claims Example

Working thesis:  Today’s teenage girls are too sexualized.

Revised thesis: Teenage girls who are captivated by the sexual images on the internet and social media are conditioned to believe that a woman’s worth depends on her sensuality, a feeling that harms their self-esteem and behavior.

Explanation:  It is true that some young women in today’s society are more sexualized than in the past, but that is not true for all girls. Many girls have strict parents, dress appropriately, and do not engage in sexual activity while in middle school and high school. The writer of this thesis should ask the following questions:

  • Which teenage girls?
  • What constitutes “too” sexualized?
  • Why are they behaving that way?
  • Where does this behavior show up?
  • What are the repercussions?

  • Teacher Tips: How to Write Thesis Statements for High School Papers

The purpose of a thesis statement is to provide a clear, specific argument that will serve as a guide to the reader so she knows what to expect from your essay. A thesis should be related to the question or prompt that your are responding to, but it should provide a specific argument that goes beyond a simple restatement of the subject. The thesis serves as the backbone of your essay, and you will support the claims that you make in your thesis throughout the piece. A good thesis will also help you as the writer know how to structure your essay and when to leave out information that is not relevant to the thesis.

Does your thesis serve its purpose?

Let's say you are writing about the U.S. Constitution. You write the following thesis statement: "The U.S. Constitution set forth principles that are still very important to our government." Now, ask yourself if this thesis is serving it's purpose. Is it a specific argument? Not really. It is an argument that no one would dispute, and it is so broad that you would need to write a book to cover all of the issues that this thesis covers. Does it serve as a guide to the reader? No, because the reader doesn't know what principles you are going to write about or why they are so important. A better thesis might be something like this: "The 'commerce clause' in Article 1, Section 8 has been the most important single line in the Constitution, influencing the size and scope of the current federal government." This is an argument that is specific enough to defend and will let your reader know exactly what your essay will be about.

Speechwriting

8 Purpose and Thesis

Speechwriting Essentials

In this chapter . . .

As discussed in the chapter on Speaking Occasion , speechwriting begins with careful analysis of the speech occasion and its given circumstances, leading to the choice of an appropriate topic. As with essay writing, the early work of speechwriting follows familiar steps: brainstorming, research, pre-writing, thesis, and so on.

This chapter focuses on techniques that are unique to speechwriting. As a spoken form, speeches must be clear  about the purpose and main idea or “takeaway.” Planned redundancy means that you will be repeating these elements several times over during the speech.

Furthermore, finding purpose and thesis are essential whether you’re preparing an outline for extemporaneous delivery or a completely written manuscript for presentation. When you know your topic, your general and specific purpose, and your thesis or central idea, you have all the elements you need to write a speech that is focused, clear, and audience friendly.

Recognizing the General Purpose

Speeches have traditionally been grouped into one of three categories according to their primary purpose: 1) to inform, 2) to persuade, or 3) to inspire, honor, or entertain. These broad goals are commonly known as the  general purpose of a speech . Earlier, you learned about the actor’s tool of intention or objectives. The general purpose is like a super-objective; it defines the broadest goal of a speech. These three purposes are not necessarily exclusive to the others. A speech designed to be persuasive can also be informative and entertaining. However, a speech should have one primary goal. That is its general purpose.

Why is it helpful to talk about speeches in such broad terms? Being perfectly clear about what you want your speech to do or make happen for your audience will keep you focused. You can make a clearer distinction between whether you want your audience to leave your speech knowing more (to inform), or  ready to take action (to persuade), or feeling something (to inspire)

It’s okay to use synonyms for these broad categories. Here are some of them:

  • To inform could be to explain, to demonstrate, to describe, to teach.
  • To persuade could be to convince, to argue, to motivate, to prove.
  • To inspire might be to honor, or entertain, to celebrate, to mourn.

In summary, the first question you must ask yourself when starting to prepare a speech is, “Is the primary purpose of my speech to inform, to persuade, or to inspire?”

Articulating Specific Purpose

A specific purpose statement builds upon your general purpose and makes it specific (as the name suggests). For example, if you have been invited to give a speech about how to do something, your general purpose is “to inform.”  Choosing a topic appropriate to that general purpose, you decide to speak about how to protect a personal from cyberattacks. Now you are on your way to identifying a specific purpose.

A good specific purpose statement has three elements: goal, target audience, and content.

If you think about the above as a kind of recipe, then the first two “ingredients” — your goal and your audience — should be simple. Words describing the target audience should be as specific as possible. Instead of “my peers,” you could say, for example, “students in their senior year at my university.”

The third ingredient in this recipe is content, or what we call the topic of your speech. This is where things get a bit difficult. You want your content to be specific and something that you can express succinctly in a sentence. Here are some common problems that speakers make in defining the content, and the fix:

Now you know the “recipe” for a specific purpose statement. It’s made up of  T o, plus an active W ord, a specific  A udience, and clearly stated  C ontent. Remember this formula: T + W + A + C.

A: for a group of new students

C: the term “plagiarism”

Here are some further examples a good specific purpose statement:

  • To explain to a group of first-year students how to join a school organization.
  • To persuade the members of the Greek society to take a spring break trip in Daytona Beach.
  • To motivate my classmates in English 101 to participate in a study abroad program.
  • To convince first-year students that they need at least seven hours of sleep per night to do well in their studies.
  • To inspire my Church community about the accomplishments of our pastor.

The General and Specific Purpose Statements are writing tools in the sense that they help you, as a speechwriter, clarify your ideas.

Creating a Thesis Statement

Once you are clear about your general purpose and specific purpose, you can turn your attention to crafting a thesis statement. A thesis is the central idea in an essay or a speech. In speechwriting, the thesis or central idea explains the message of the content. It’s the speech’s “takeaway.” A good thesis statement will also reveal and clarify the ideas or assertions you’ll be addressing in your speech (your main points). Consider this example:

General Purpose: To persuade. Specific Purpose: To motivate my classmates in English 101 to participate in a study abroad program. Thesis: A semester-long study abroad experience produces lifelong benefits by teaching you about another culture, developing your language skills, and enhancing your future career prospects.

The difference between a specific purpose statement and a thesis statement is clear in this example. The thesis provides the takeaway (the lifelong benefits of study abroad). It also points to the assertions that will be addressed in the speech. Like the specific purpose statement, the thesis statement is a writing tool. You’ll incorporate it into your speech, usually as part of the introduction and conclusion.

All good expository, rhetorical, and even narrative writing contains a thesis. Many students and even experienced writers struggle with formulating a thesis. We struggle when we attempt to “come up with something” before doing the necessary research and reflection. A thesis only becomes clear through the thinking and writing process. As you develop your speech content, keep asking yourself: What is important here? If the audience can remember only one thing about this topic, what do I want them to remember?

Example #2: General Purpose: To inform Specific Purpose: To demonstrate to my audience the correct method for cleaning a computer keyboard. Central Idea: Your computer keyboard needs regular cleaning to function well, and you can achieve that in four easy steps.
Example # 3 General Purpose: To Inform Specific Purpose: To describe how makeup is done for the TV show The Walking Dead . Central Idea: The wildly popular zombie show The Walking Dead achieves incredibly scary and believable makeup effects, and in the next few minutes I will tell you who does it, what they use, and how they do it.

Notice in the examples above that neither the specific purpose nor the central idea ever exceeds one sentence. If your central idea consists of more than one sentence, then you are probably including too much information.

Problems to Avoid

The first problem many students have in writing their specific purpose statement has already been mentioned: specific purpose statements sometimes try to cover far too much and are too broad. For example:

“To explain to my classmates the history of ballet.”

Aside from the fact that this subject may be difficult for everyone in your audience to relate to, it’s enough for a three-hour lecture, maybe even a whole course. You’ll probably find that your first attempt at a specific purpose statement will need refining. These examples are much more specific and much more manageable given the limited amount of time you’ll have.

  • To explain to my classmates how ballet came to be performed and studied in the U.S.
  • To explain to my classmates the difference between Russian and French ballet.
  • To explain to my classmates how ballet originated as an art form in the Renaissance.
  • To explain to my classmates the origin of the ballet dancers’ clothing.

The second problem happens when the “communication verb” in the specific purpose does not match the content; for example, persuasive content is paired with “to inform” or “to explain.” Can you find the errors in the following purpose statements?

  • To inform my audience why capital punishment is unconstitutional. (This is persuasive. It can’t be informative since it’s taking a side)
  • To persuade my audience about the three types of individual retirement accounts. (Even though the purpose statement says “persuade,” it isn’t persuading the audience of anything. It is informative.)
  • To inform my classmates that Universal Studios is a better theme park than Six Flags over Georgia. (This is clearly an opinion; hence it is a persuasive speech and not merely informative)

The third problem exists when the content part of the specific purpose statement has two parts. One specific purpose is enough. These examples cover two different topics.

  • To explain to my audience how to swing a golf club and choose the best golf shoes.
  • To persuade my classmates to be involved in the Special Olympics and vote to fund better classes for the intellectually disabled.

To fix this problem of combined or hybrid purposes, you’ll need to select one of the topics in these examples and speak on that one alone.

The fourth problem with both specific purpose and central idea statements is related to formatting. There are some general guidelines that need to be followed in terms of how you write out these elements of your speech:

  • Don’t write either statement as a question.
  • Always use complete sentences for central idea statements and infinitive phrases (beginning with “to”) for the specific purpose statement.
  • Use concrete language (“I admire Beyoncé for being a talented performer and businesswoman”) and avoid subjective or slang terms (“My speech is about why I think Beyoncé is the bomb”) or jargon and acronyms (“PLA is better than CBE for adult learners.”)

There are also problems to avoid in writing the central idea statement. As mentioned above, remember that:

  • The specific purpose and central idea statements are not the same thing, although they are related.
  • The central idea statement should be clear and not complicated or wordy; it should “stand out” to the audience. As you practice delivery, you should emphasize it with your voice.
  • The central idea statement should not be the first thing you say but should follow the steps of a good introduction as outlined in the next chapters.

You should be aware that all aspects of your speech are constantly going to change as you move toward the moment of giving your speech. The exact wording of your central idea may change, and you can experiment with different versions for effectiveness. However, your specific purpose statement should not change unless there is a good reason to do so. There are many aspects to consider in the seemingly simple task of writing a specific purpose statement and its companion, the central idea statement. Writing good ones at the beginning will save you some trouble later in the speech preparation process.

Distinguishing between ethical and normative behaviors in engineering

Background: Though ethics has been recognized as an important aspect of engineering education, there is not a definitive consensus on what ethical engineering is. This dissertation seeks to understand what constitutes ethical behaviors in engineering by distinguishing them from other normative behaviors.

Purpose: This study aims to understand what ethical engineering looks like in practice by addressing the research question: To what extent do engineering ethics experts agree when normative behaviors in engineering are also ethical in nature? While definitions of what constitutes ethical engineering practice are varied in the literature and have been debated theoretically by scholars, this study adopts an empirical approach to understand how experts in engineering ethics conceptualize ethical behaviors in engineering.

Methods: This dissertation study uses a Delphi process to build consensus among experts on what behaviors constitute ethical engineering practice. The Delphi panel consisted of 27 scholars, educators, and practicing engineers with expertise in engineering ethics who provided iterative feedback across three rounds of data collection through questionnaires. Round 1 generated 25 statements of normative behaviors in engineering. Round 2 prompted panelists to judge the ethicality of each behavior. Round 3 presented panelists with the aggregated responses and opinions from the previous round and invited them to revise their judgments.

Findings: The results of the Delphi process identified areas of consensus and disagreement among the panel on which normative behaviors in engineering are generally considered ethical or non-ethical in nature. Of the 25 statements, panelists agreed that 20 of the behaviors tended to be ethical in nature and one behavior tended to be non-ethical in nature, while the remaining four statements did not yield consensus.

Contribution: This research aims to provide clarity around what constitutes ethical behaviors in engineering by differentiating them conceptually from other normative behaviors in engineering practice. The empirical approach taken in this study has implications for research, teaching, and assessment in engineering ethics education. Specifically, the questionnaire developed through the Delphi process can be deployed to study engineering students and practitioners to make broader claims about what is ethical in engineering.
