How to Conclude an Essay | Interactive Example

Published on January 24, 2019 by Shona McCombes . Revised on July 23, 2023.

The conclusion is the final paragraph of your essay . A strong conclusion aims to:

• Tie together the essay’s main points
• Show why your argument matters
• Leave the reader with a strong impression

Your conclusion should give a sense of closure and completion to your argument, but also show what new questions or possibilities it has opened up.

This conclusion is taken from our annotated essay example , which discusses the history of the Braille system. Hover over each part to see why it’s effective.

Braille paved the way for dramatic cultural changes in the way blind people were treated and the opportunities available to them. Louis Braille’s innovation was to reimagine existing reading systems from a blind perspective, and the success of this invention required sighted teachers to adapt to their students’ reality instead of the other way around. In this sense, Braille helped drive broader social changes in the status of blindness. New accessibility tools provide practical advantages to those who need them, but they can also change the perspectives and attitudes of those who do not.

To begin your conclusion, signal that the essay is coming to an end by returning to your overall argument.

Don’t just repeat your thesis statement —instead, try to rephrase your argument in a way that shows how it has been developed since the introduction.

Prevent plagiarism. Run a free check.

Next, remind the reader of the main points that you used to support your argument.

Avoid simply summarizing each paragraph or repeating each point in order; try to bring your points together in a way that makes the connections between them clear. The conclusion is your final chance to show how all the paragraphs of your essay add up to a coherent whole.

To wrap up your conclusion, zoom out to a broader view of the topic and consider the implications of your argument. For example:

• Does it contribute a new understanding of your topic?
• Does it raise new questions for future study?
• Does it lead to practical suggestions or predictions?
• Can it be applied to different contexts?
• Can it be connected to a broader debate or theme?

Whatever your essay is about, the conclusion should aim to emphasize the significance of your argument, whether that’s within your academic subject or in the wider world.

Try to end with a strong, decisive sentence, leaving the reader with a lingering sense of interest in your topic.

The easiest way to improve your conclusion is to eliminate these common mistakes.

Don’t include new evidence

Any evidence or analysis that is essential to supporting your thesis statement should appear in the main body of the essay.

The conclusion might include minor pieces of new information—for example, a sentence or two discussing broader implications, or a quotation that nicely summarizes your central point. But it shouldn’t introduce any major new sources or ideas that need further explanation to understand.

Don’t use “concluding phrases”

Avoid using obvious stock phrases to tell the reader what you’re doing:

• “In conclusion…”
• “To sum up…”

These phrases aren’t forbidden, but they can make your writing sound weak. By returning to your main argument, it will quickly become clear that you are concluding the essay—you shouldn’t have to spell it out.

Don’t undermine your argument

Avoid using apologetic phrases that sound uncertain or confused:

• “This is just one approach among many.”
• “There are good arguments on both sides of this issue.”
• “There is no clear answer to this problem.”

Even if your essay has explored different points of view, your own position should be clear. There may be many possible approaches to the topic, but you want to leave the reader convinced that yours is the best one!

This conclusion is taken from an argumentative essay about the internet’s impact on education. It acknowledges the opposing arguments while taking a clear, decisive position.

The internet has had a major positive impact on the world of education; occasional pitfalls aside, its value is evident in numerous applications. The future of teaching lies in the possibilities the internet opens up for communication, research, and interactivity. As the popularity of distance learning shows, students value the flexibility and accessibility offered by digital education, and educators should fully embrace these advantages. The internet’s dangers, real and imaginary, have been documented exhaustively by skeptics, but the internet is here to stay; it is time to focus seriously on its potential for good.

This conclusion is taken from a short expository essay that explains the invention of the printing press and its effects on European society. It focuses on giving a clear, concise overview of what was covered in the essay.

The invention of the printing press was important not only in terms of its immediate cultural and economic effects, but also in terms of its major impact on politics and religion across Europe. In the century following the invention of the printing press, the relatively stationary intellectual atmosphere of the Middle Ages gave way to the social upheavals of the Reformation and the Renaissance. A single technological innovation had contributed to the total reshaping of the continent.

This conclusion is taken from a literary analysis essay about Mary Shelley’s Frankenstein . It summarizes what the essay’s analysis achieved and emphasizes its originality.

By tracing the depiction of Frankenstein through the novel’s three volumes, I have demonstrated how the narrative structure shifts our perception of the character. While the Frankenstein of the first volume is depicted as having innocent intentions, the second and third volumes—first in the creature’s accusatory voice, and then in his own voice—increasingly undermine him, causing him to appear alternately ridiculous and vindictive. Far from the one-dimensional villain he is often taken to be, the character of Frankenstein is compelling because of the dynamic narrative frame in which he is placed. In this frame, Frankenstein’s narrative self-presentation responds to the images of him we see from others’ perspectives. This conclusion sheds new light on the novel, foregrounding Shelley’s unique layering of narrative perspectives and its importance for the depiction of character.

Your essay’s conclusion should contain:

• A rephrased version of your overall thesis
• A brief review of the key points you made in the main body
• An indication of why your argument matters

The conclusion may also reflect on the broader implications of your argument, showing how your ideas could applied to other contexts or debates.

For a stronger conclusion paragraph, avoid including:

• Important evidence or analysis that wasn’t mentioned in the main body
• Generic concluding phrases (e.g. “In conclusion…”)
• Weak statements that undermine your argument (e.g. “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

The conclusion paragraph of an essay is usually shorter than the introduction . As a rule, it shouldn’t take up more than 10–15% of the text.

Conclusions

What this handout is about.

This handout will explain the functions of conclusions, offer strategies for writing effective ones, help you evaluate conclusions you’ve drafted, and suggest approaches to avoid.

About conclusions

Introductions and conclusions can be difficult to write, but they’re worth investing time in. They can have a significant influence on a reader’s experience of your paper.

Just as your introduction acts as a bridge that transports your readers from their own lives into the “place” of your analysis, your conclusion can provide a bridge to help your readers make the transition back to their daily lives. Such a conclusion will help them see why all your analysis and information should matter to them after they put the paper down.

Your conclusion is your chance to have the last word on the subject. The conclusion allows you to have the final say on the issues you have raised in your paper, to synthesize your thoughts, to demonstrate the importance of your ideas, and to propel your reader to a new view of the subject. It is also your opportunity to make a good final impression and to end on a positive note.

Your conclusion can go beyond the confines of the assignment. The conclusion pushes beyond the boundaries of the prompt and allows you to consider broader issues, make new connections, and elaborate on the significance of your findings.

Your conclusion should make your readers glad they read your paper. Your conclusion gives your reader something to take away that will help them see things differently or appreciate your topic in personally relevant ways. It can suggest broader implications that will not only interest your reader, but also enrich your reader’s life in some way. It is your gift to the reader.

Strategies for writing an effective conclusion

One or more of the following strategies may help you write an effective conclusion:

• Play the “So What” Game. If you’re stuck and feel like your conclusion isn’t saying anything new or interesting, ask a friend to read it with you. Whenever you make a statement from your conclusion, ask the friend to say, “So what?” or “Why should anybody care?” Then ponder that question and answer it. Here’s how it might go: You: Basically, I’m just saying that education was important to Douglass. Friend: So what? You: Well, it was important because it was a key to him feeling like a free and equal citizen. Friend: Why should anybody care? You: That’s important because plantation owners tried to keep slaves from being educated so that they could maintain control. When Douglass obtained an education, he undermined that control personally. You can also use this strategy on your own, asking yourself “So What?” as you develop your ideas or your draft.
• Return to the theme or themes in the introduction. This strategy brings the reader full circle. For example, if you begin by describing a scenario, you can end with the same scenario as proof that your essay is helpful in creating a new understanding. You may also refer to the introductory paragraph by using key words or parallel concepts and images that you also used in the introduction.
• Synthesize, don’t summarize. Include a brief summary of the paper’s main points, but don’t simply repeat things that were in your paper. Instead, show your reader how the points you made and the support and examples you used fit together. Pull it all together.
• Include a provocative insight or quotation from the research or reading you did for your paper.
• Propose a course of action, a solution to an issue, or questions for further study. This can redirect your reader’s thought process and help them to apply your info and ideas to their own life or to see the broader implications.
• Point to broader implications. For example, if your paper examines the Greensboro sit-ins or another event in the Civil Rights Movement, you could point out its impact on the Civil Rights Movement as a whole. A paper about the style of writer Virginia Woolf could point to her influence on other writers or on later feminists.

Strategies to avoid

• Beginning with an unnecessary, overused phrase such as “in conclusion,” “in summary,” or “in closing.” Although these phrases can work in speeches, they come across as wooden and trite in writing.
• Stating the thesis for the very first time in the conclusion.
• Introducing a new idea or subtopic in your conclusion.
• Ending with a rephrased thesis statement without any substantive changes.
• Making sentimental, emotional appeals that are out of character with the rest of an analytical paper.
• Including evidence (quotations, statistics, etc.) that should be in the body of the paper.

Four kinds of ineffective conclusions

• The “That’s My Story and I’m Sticking to It” Conclusion. This conclusion just restates the thesis and is usually painfully short. It does not push the ideas forward. People write this kind of conclusion when they can’t think of anything else to say. Example: In conclusion, Frederick Douglass was, as we have seen, a pioneer in American education, proving that education was a major force for social change with regard to slavery.
• The “Sherlock Holmes” Conclusion. Sometimes writers will state the thesis for the very first time in the conclusion. You might be tempted to use this strategy if you don’t want to give everything away too early in your paper. You may think it would be more dramatic to keep the reader in the dark until the end and then “wow” them with your main idea, as in a Sherlock Holmes mystery. The reader, however, does not expect a mystery, but an analytical discussion of your topic in an academic style, with the main argument (thesis) stated up front. Example: (After a paper that lists numerous incidents from the book but never says what these incidents reveal about Douglass and his views on education): So, as the evidence above demonstrates, Douglass saw education as a way to undermine the slaveholders’ power and also an important step toward freedom.
• The “America the Beautiful”/”I Am Woman”/”We Shall Overcome” Conclusion. This kind of conclusion usually draws on emotion to make its appeal, but while this emotion and even sentimentality may be very heartfelt, it is usually out of character with the rest of an analytical paper. A more sophisticated commentary, rather than emotional praise, would be a more fitting tribute to the topic. Example: Because of the efforts of fine Americans like Frederick Douglass, countless others have seen the shining beacon of light that is education. His example was a torch that lit the way for others. Frederick Douglass was truly an American hero.
• The “Grab Bag” Conclusion. This kind of conclusion includes extra information that the writer found or thought of but couldn’t integrate into the main paper. You may find it hard to leave out details that you discovered after hours of research and thought, but adding random facts and bits of evidence at the end of an otherwise-well-organized essay can just create confusion. Example: In addition to being an educational pioneer, Frederick Douglass provides an interesting case study for masculinity in the American South. He also offers historians an interesting glimpse into slave resistance when he confronts Covey, the overseer. His relationships with female relatives reveal the importance of family in the slave community.

How to Write a Conclusion for an Essay

By the time you get to the final paragraph of your paper, you have already done so much work on your essay, so all you want to do is to wrap it up as quickly as possible. You’ve already made a stunning introduction, proven your argument, and structured the whole piece as supposed – who cares about making a good conclusion paragraph?

The only thing you need to remember is that the conclusion of an essay is not just the last paragraph of an academic paper where you restate your thesis and key arguments. A concluding paragraph is also your opportunity to have a final impact on your audience. 

Feeling Overwhelmed Writing Your Essay Conclusion?

Simply send us your paper requirements, choose a writer and we’ll get it done fast.

How to write a conclusion paragraph that leaves a lasting impression – In this guide, the team at EssayPro is going to walk you through the process of writing a perfect conclusion step by step. Additionally, we will share valuable tips and tricks to help students of all ages impress their readers at the last moment.

Instead of Intro: What Is a Conclusion?

Before we can move on, let’s take a moment here to define the conclusion itself. According to the standard conclusion definition, it is pretty much the last part of something, its result, or end. However, this term is rather broad and superficial.

When it comes to writing academic papers, a concluding statement refers to an opinion, judgment, suggestion, or position arrived at by logical reasoning (through the arguments provided in the body of the text). Therefore, if you are wondering “what is a good closing sentence like?” – keep on reading.

What Does a Good Conclusion Mean?

Writing a good conclusion for a paper isn’t easy. However, we are going to walk you through this process step by step. Although there are generally no strict rules on how to formulate one, there are some basic principles that everyone should keep in mind. In this section, we will share some core ideas for writing a good conclusion, and, later in the article, we will also provide you with more practical advice and examples.

Here are the core goals a good conclusion should complete:

• “Wrap up” the entire paper;
• Demonstrate to readers that the author accomplished what he/she set out to do;
• Show how you the author has proved their thesis statement;
• Give a sense of completeness and closure on the topic;
• Leave something extra for your reader to think about;
• Leave a powerful final impact on a reader.

Another key thing to remember is that you should not introduce any new ideas or arguments to your paper's conclusion. It should only sum up what you have already written, revisit your thesis statement, and end with a powerful final impression.

When considering how to write a conclusion that works, here are the key points to keep in mind:

• A concluding sentence should only revisit the thesis statement, not restate it;
• It should summarize the main ideas from the body of the paper;
• It should demonstrate the significance and relevance of your work;
• An essay’s conclusion should include a call for action and leave space for further study or development of the topic (if necessary).

How Long Should a Conclusion Be? 

Although there are no strict universal rules regarding the length of an essay’s final clause, both teachers and experienced writers recommend keeping it clear, concise, and straight to the point. There is an unspoken rule that the introduction and conclusion of an academic paper should both be about 10% of the overall paper’s volume. For example, if you were assigned a 1500 word essay, both the introductory and final clauses should be approximately 150 words long (300 together).

Why You Need to Know How to End an Essay:

A conclusion is what drives a paper to its logical end. It also drives the main points of your piece one last time. It is your last opportunity to impact and impress your audience. And, most importantly, it is your chance to demonstrate to readers why your work matters. Simply put, the final paragraph of your essay should answer the last important question a reader will have – “So what?”

If you do a concluding paragraph right, it can give your readers a sense of logical completeness. On the other hand, if you do not make it powerful enough, it can leave them hanging, and diminish the effect of the entire piece.

Strategies to Crafting a Proper Conclusion

Although there are no strict rules for what style to use to write your conclusion, there are several strategies that have been proven to be effective. In the list below, you can find some of the most effective strategies with some good conclusion paragraph examples to help you grasp the idea.

One effective way to emphasize the significance of your essay and give the audience some thought to ponder about is by taking a look into the future. The “When and If” technique is quite powerful when it comes to supporting your points in the essay’s conclusion.

Prediction essay conclusion example: “Taking care of a pet is quite hard, which is the reason why most parents refuse their children’s requests to get a pet. However, the refusal should be the last choice of parents. If we want to inculcate a deep sense of responsibility and organization in our kids, and, at the same time, sprout compassion in them, we must let our children take care of pets.”

Another effective strategy is to link your conclusion to your introductory paragraph. This will create a full-circle narration for your readers, create a better understanding of your topic, and emphasize your key point.

Echo conclusion paragraph example: Introduction: “I believe that all children should grow up with a pet. I still remember the exact day my parents brought my first puppy to our house. This was one of the happiest moments in my life and, at the same time, one of the most life-changing ones. Growing up with a pet taught me a lot, and most importantly, it taught me to be responsible.” Conclusion:. “I remember when I picked up my first puppy and how happy I was at that time. Growing up with a pet, I learned what it means to take care of someone, make sure that he always has water and food, teach him, and constantly keep an eye on my little companion. Having a child grow up with a pet teaches them responsibility and helps them acquire a variety of other life skills like leadership, love, compassion, and empathy. This is why I believe that every kid should grow up with a pet!”

Finally, one more trick that will help you create a flawless conclusion is to amplify your main idea or to present it in another perspective of a larger context. This technique will help your readers to look at the problem discussed from a different angle.

Step-up argumentative essay conclusion example: “Despite the obvious advantages of owning a pet in childhood, I feel that we cannot generalize whether all children should have a pet. Whereas some kids may benefit from such experiences, namely, by becoming more compassionate, organized, and responsible, it really depends on the situation, motivation, and enthusiasm of a particular child for owning a pet.”

What is a clincher in an essay? – The final part of an essay’s conclusion is often referred to as a clincher sentence. According to the clincher definition, it is a final sentence that reinforces the main idea or leaves the audience with an intriguing thought to ponder upon. In a nutshell, the clincher is very similar to the hook you would use in an introductory paragraph. Its core mission is to seize the audience’s attention until the end of the paper. At the same time, this statement is what creates a sense of completeness and helps the author leave a lasting impression on the reader.

Now, since you now know what a clincher is, you are probably wondering how to use one in your own paper. First of all, keep in mind that a good clincher should be intriguing, memorable, smooth, and straightforward.

Generally, there are several different tricks you can use for your clincher statement; it can be:

• A short, but memorable and attention-grabbing conclusion;
• A relevant and memorable quote (only if it brings actual value);
• A call to action;
• A rhetorical question;
• An illustrative story or provocative example;
• A warning against a possibility or suggestion about the consequences of a discussed problem;
• A joke (however, be careful with this as it may not always be deemed appropriate).

Regardless of the technique you choose, make sure that your clincher is memorable and aligns with your introduction and thesis.

Clincher examples: - While New York may not be the only place with the breathtaking views, it is definitely among my personal to 3… and that’s what definitely makes it worth visiting. - “Thence we came forth to rebehold the stars”, Divine Comedy - Don’t you think all these advantages sound like almost life-saving benefits of owning a pet? “So we beat on, boats against the current, borne back ceaselessly into the past.”, The Great Gatsby

Conclusion Writing Don'ts 

Now, when you know what tricks and techniques you should use to create a perfect conclusion, let’s look at some of the things you should not do with our online paper writing service :

• Starting with some cliché concluding sentence starters. Many students find common phrases like “In conclusion,” “Therefore,” “In summary,” or similar statements to be pretty good conclusion starters. However, though such conclusion sentence starters may work in certain cases – for example, in speeches – they are overused, so it is recommended not to use them in writing to introduce your conclusion.
• Putting the first mention of your thesis statement in the conclusion – it has to be presented in your introduction first.
• Providing new arguments, subtopics, or ideas in the conclusion paragraph.
• Including a slightly changed or unchanged thesis statement.
• Providing arguments and evidence that belong in the body of the work.
• Writing too long, hard to read, or confusing sentences.

In case, you have written a conclusion, but you're not sure if it’s good enough?

Conclusion Paragraph Outline

The total number of sentences in your final paragraph may vary depending on the number of points you discussed in your essay, as well as on the overall word count of your paper. However, the overall conclusion paragraph outline will remain the same and consists of the following elements:

• A conclusion starter:

The first part of your paragraph should drive readers back to your thesis statement. Thus, if you were wondering how to start a conclusion, the best way to do it is by rephrasing your thesis statement.

• Summary of the body paragraphs:

Right after revisiting your thesis, you should include several sentences that wrap up the key highlights and points from your body paragraphs. This part of your conclusion can consist of 2-3 sentences—depending on the number of arguments you’ve made. If necessary, you can also explain to the readers how your main points fit together.

• A concluding sentence:

Finally, you should end your paragraph with a last, powerful sentence that leaves a lasting impression, gives a sense of logical completeness, and connects readers back to the introduction of the paper.

These three key elements make up a perfect essay conclusion. Now, to give you an even better idea of how to create a perfect conclusion, let us give you a sample conclusion paragraph outline with examples from an argumentative essay on the topic of “Every Child Should Own a Pet:

• Sentence 1: Starter
• ~ Thesis: "Though taking care of a pet may be a bit challenging for small children. Parents should not restrict their kids from having a pet as it helps them grow into more responsible and compassionate people."
• ~ Restated thesis for a conclusion: "I can say that taking care of a pet is good for every child."
• Sentences 2-4: Summary
• ~ "Studies have shown that pet owners generally have fewer health problems."
• ~ "Owning a pet teaches a child to be more responsible."
• ~ "Spending time with a pet reduces stress, feelings of loneliness, and anxiety."
• Sentence 5: A concluding sentence
• ~ "Pets can really change a child life for the better, so don't hesitate to endorse your kid's desire to own a pet."

This is a clear example of how you can shape your conclusion paragraph.

How to Conclude Various Types of Essays

Depending on the type of academic essay you are working on, your concluding paragraph's style, tone, and length may vary. In this part of our guide, we will tell you how to end different types of essays and other works.

How to End an Argumentative Essay

Persuasive or argumentative essays always have the single goal of convincing readers of something (an idea, stance, or viewpoint) by appealing to arguments, facts, logic, and even emotions. The conclusion for such an essay has to be persuasive as well. A good trick you can use is to illustrate a real-life scenario that proves your stance or encourages readers to take action. More about persuasive essay outline you can read in our article.

Here are a few more tips for making a perfect conclusion for an argumentative essay:

• Carefully read the whole essay before you begin;
• Re-emphasize your ideas;
• Discuss possible implications;
• Don’t be afraid to appeal to the reader’s emotions.

How to End a Compare and Contrast Essay

The purpose of a compare and contrast essay is to emphasize the differences or similarities between two or more objects, people, phenomena, etc. Therefore, a logical conclusion should highlight how the reviewed objects are different or similar. Basically, in such a paper, your conclusion should recall all of the key common and distinctive features discussed in the body of your essay and also give readers some food for thought after they finish reading it.

How to Conclude a Descriptive Essay

The key idea of a descriptive essay is to showcase your creativity and writing skills by painting a vivid picture with the help of words. This is one of the most creative types of essays as it requires you to show a story, not tell it. This kind of essay implies using a lot of vivid details. Respectively, the conclusion of such a paper should also use descriptive imagery and, at the same time, sum up the main ideas. A good strategy for ending a descriptive essay would be to begin with a short explanation of why you wrote the essay. Then, you should reflect on how your topic affects you. In the middle of the conclusion, you should cover the most critical moments of the story to smoothly lead the reader into a logical closing statement. The “clincher”, in this case, should be a thought-provoking final sentence that leaves a good and lasting impression on the audience. Do not lead the reader into the essay and then leave them with dwindling memories of it.

How to Conclude an Essay About Yourself

If you find yourself writing an essay about yourself, you need to tell a personal story. As a rule, such essays talk about the author’s experiences, which is why a conclusion should create a feeling of narrative closure. A good strategy is to end your story with a logical finale and the lessons you have learned, while, at the same time, linking it to the introductory paragraph and recalling key moments from the story.

How to End an Informative Essay

Unlike other types of papers, informative or expository essays load readers with a lot of information and facts. In this case, “Synthesize, don’t summarize” is the best technique you can use to end your paper. Simply put, instead of recalling all of the major facts, you should approach your conclusion from the “So what?” position by highlighting the significance of the information provided.

How to Conclude a Narrative Essay

In a nutshell, a narrative essay is based on simple storytelling. The purpose of this paper is to share a particular story in detail. Therefore, the conclusion for such a paper should wrap up the story and avoid finishing on an abrupt cliffhanger. It is vital to include the key takeaways and the lessons learned from the story.

How to Write a Conclusion for a Lab Report

Unlike an essay, a lab report is based on an experiment. This type of paper describes the flow of a particular experiment conducted by a student and its conclusion should reflect on the outcomes of this experiment.

In thinking of how to write a conclusion for a lab, here are the key things you should do to get it right:

• Restate the goals of your experiment
• Describe the methods you used
• Include the results of the experiment and analyze the final data
• End your conclusion with a clear statement on whether or not the experiment was successful (Did you reach the expected results?)

How to Write a Conclusion for a Research Paper

Writing a paper is probably the hardest task of all, even for experienced dissertation writer . Unlike an essay or even a lab report, a research paper is a much longer piece of work that requires a deeper investigation of the problem. Therefore, a conclusion for such a paper should be even more sophisticated and powerful. If you're feeling difficulty writing an essay, you can buy essay on our service.

However, given that a research paper is the second most popular kind of academic paper (after an essay), it is important to know how to conclude a research paper. Even if you have not yet been assigned to do this task, be sure that you will face it soon. So, here are the steps you should follow to create a great conclusion for a research paper:

• Restate the Topic

Start your final paragraph with a quick reminder of what the topic of the piece is about. Keep it one sentence long.

• Revisit the Thesis

Next, you should remind your readers what your thesis statement was. However, do not just copy and paste it from the introductory clause: paraphrase your thesis so that you deliver the same idea but with different words. Keep your paraphrased thesis narrow, specific, and topic-oriented.

• Summarise Your Key Ideas

Just like the case of a regular essay’s conclusion, a research paper’s final paragraph should also include a short summary of all of the key points stated in the body sections. We recommend reading the entire body part a few times to define all of your main arguments and ideas.

• Showcase the Significance of Your Work

In the research paper conclusion, it is vital to highlight the significance of your research problem and state how your solution could be helpful.

• Make Suggestions for Future Studies

Finally, at the end of your conclusion, you should define how your findings will contribute to the development of its particular field of science. Outline the perspectives of further research and, if necessary, explain what is yet to be discovered on the topic.

Then, end your conclusion with a powerful concluding sentence – it can be a rhetorical question, call to action, or another hook that will help you have a strong impact on the audience.

So, What Is a Good Closing Sentence? See The Difference

One of the best ways to learn how to write a good conclusion is to look at several professional essay conclusion examples. In this section of our guide, we are going to look at two different final paragraphs shaped on the basis of the same template, but even so, they are very different – where one is weak and the other is strong. Below, we are going to compare them to help you understand the difference between a good and a bad conclusion.

Here is the template we used: College degrees are in decline. The price of receiving an education does not correlate with the quality of the education received. As a result, graduated students face underemployment, and the worth of college degrees appears to be in serious doubt. However, the potential social and economic benefits of educated students balance out the equation.

Strong Conclusion ‍

People either see college as an opportunity or an inconvenience; therefore, a degree can only hold as much value as its owner’s skillset. The underemployment of graduate students puts the worth of college degrees in serious doubt. Yet, with the multitude of benefits that educated students bring to society and the economy, the equation remains in balance. Perhaps the ordinary person should consider college as a wise financial investment, but only if they stay determined to study and do the hard work.

Why is this example good? There are several key points that prove its effectiveness:

• There is a bold opening statement that encompasses the two contrasting types of students we can see today.
• There are two sentences that recall the thesis statement and cover the key arguments from the body of the essay.
• Finally, the last sentence sums up the key message of the essay and leaves readers with something to think about.

Weak Conclusion

In conclusion, with the poor preparation of students in college and the subsequent underemployment after graduation from college, the worth associated with the college degree appears to be in serious doubt. However, these issues alone may not reasonably conclude beyond a doubt that investing in a college degree is a rewarding venture. When the full benefits that come with education are carefully put into consideration and evaluated, college education for children in any country still has good advantages, and society should continue to advocate for a college education. The ordinary person should consider this a wise financial decision that holds rewards in the end. Apart from the monetary gains associated with a college education, society will greatly benefit from students when they finish college. Their minds are going to be expanded, and their reasoning and decision making will be enhanced.

What makes this example bad? Here are a few points to consider:

• Unlike the first example, this paragraph is long and not specific enough. The author provides plenty of generalized phrases that are not backed up by actual arguments.
• This piece is hard to read and understand and sentences have a confusing structure. Also, there are lots of repetitions and too many uses of the word “college”.
• There is no summary of the key benefits.
• The last two sentences that highlight the value of education contradict with the initial statement.
• Finally, the last sentence doesn’t offer a strong conclusion and gives no thought to ponder upon.
• In the body of your essay, you have hopefully already provided your reader(s) with plenty of information. Therefore, it is not wise to present new arguments or ideas in your conclusion.
• To end your final paragraph right, find a clear and straightforward message that will have the most powerful impact on your audience.
• Don’t use more than one quote in the final clause of your paper – the information from external sources (including quotes) belongs in the body of a paper.
• Be authoritative when writing a conclusion. You should sound confident and convincing to leave a good impression. Sentences like “I’m not an expert, but…” will most likely make you seem less knowledgeable and/or credible.

Good Conclusion Examples

Now that we've learned what a conclusion is and how to write one let's take a look at some essay conclusion examples to strengthen our knowledge.

The ending ironically reveals that all was for nothing. (A short explanation of the thematic effect of the book’s end) Tom says that Miss Watson freed Jim in her final will.Jim told Huck that the dead man on the Island was pap. The entire adventure seemingly evaporated into nothingness. (How this effect was manifested into the minds of thereaders).

All in all, international schools hold the key to building a full future that students can achieve. (Thesis statement simplified) They help students develop their own character by learning from their mistakes, without having to face a dreadful penalty for failure. (Thesis statement elaborated)Although some say that kids emerged “spoiled” with this mentality, the results prove the contrary. (Possible counter-arguments are noted)

In conclusion, public workers should be allowed to strike since it will give them a chance to air their grievances. (Thesis statement) Public workers should be allowed to strike when their rights, safety, and regulations are compromised. The workers will get motivated when they strike, and their demands are met.

In summary, studies reveal some similarities in the nutrient contents between the organic and non-organic food substances. (Starts with similarities) However, others have revealed many considerable differences in the amounts of antioxidants as well as other minerals present in organic and non-organic foods. Generally, organic foods have higher levels of antioxidants than non-organic foods and therefore are more important in the prevention of chronic illnesses.

As time went by, my obsession grew into something bigger than art; (‘As time went by’ signals maturation) it grew into a dream of developing myself for the world. (Showing student’s interest of developing himself for the community) It is a dream of not only seeing the world from a different perspective but also changing the perspective of people who see my work. (Showing student’s determination to create moving pieces of art)

In conclusion, it is evident that technology is an integral part of our lives and without it, we become “lost” since we have increasingly become dependent on its use. (Thesis with main point)

How to Write an Essay Conclusion

4-minute read

• 1st October 2022

Regardless of what you’re studying, writing essays is probably a significant part of your work as a student . Taking the time to understand how to write each section of an essay (i.e., introduction, body, and conclusion) can make the entire process easier and ensure that you’ll be successful.

Once you’ve put in the hard work of writing a coherent and compelling essay, it can be tempting to quickly throw together a conclusion without the same attention to detail. However, you won’t leave an impactful final impression on your readers without a strong conclusion.

We’ve compiled a few easy steps to help you write a great conclusion for your next essay . Watch our video, or check out our guide below to learn more!

1. Return to Your Thesis

Similar to how an introduction should capture your reader’s interest and present your argument, a conclusion should show why your argument matters and leave the reader with further curiosity about the topic.

To do this, you should begin by reminding the reader of your thesis statement. While you can use similar language and keywords when referring to your thesis, avoid copying it from the introduction and pasting it into your conclusion.

Try varying your vocabulary and sentence structure and presenting your thesis in a way that demonstrates how your argument has evolved throughout your essay.

2. Review Your Main Points

In addition to revisiting your thesis statement, you should review the main points you presented in your essay to support your argument.

However, a conclusion isn’t simply a summary of your essay . Rather, you should further examine your main points and demonstrate how each is connected.

Try to discuss these points concisely, in just a few sentences, in preparation for demonstrating how they fit in to the bigger picture of the topic.

3. Show the Significance of Your Essay

Next, it’s time to think about the topic of your essay beyond the scope of your argument. It’s helpful to keep the question “so what?” in mind when you’re doing this. The goal is to demonstrate why your argument matters.

If you need some ideas about what to discuss to show the significance of your essay, consider the following:

• What do your findings contribute to the current understanding of the topic?
• Did your findings raise new questions that would benefit from future research?
• Can you offer practical suggestions for future research or make predictions about the future of the field/topic?
• Are there other contexts, topics, or a broader debate that your ideas can be applied to?

While writing your essay, it can be helpful to keep a list of ideas or insights that you develop about the implications of your work so that you can refer back to it when you write the conclusion.

Making these kinds of connections will leave a memorable impression on the reader and inspire their interest in the topic you’ve written about.

4. Avoid Some Common Mistakes

To ensure you’ve written a strong conclusion that doesn’t leave your reader confused or lacking confidence in your work, avoid:

• Presenting new evidence: Don’t introduce new information or a new argument, as it can distract from your main topic, confuse your reader, and suggest that your essay isn’t organized.
• Undermining your argument: Don’t use statements such as “I’m not an expert,” “I feel,” or “I think,” as lacking confidence in your work will weaken your argument.
• Using generic statements: Don’t use generic concluding statements such as “In summary,” “To sum up,” or “In conclusion,” which are redundant since the reader will be able to see that they’ve reached the end of your essay.

Finally, don’t make the mistake of forgetting to proofread your essay ! Mistakes can be difficult to catch in your own writing, but they can detract from your writing.

How to write an essay: Conclusion

• What's in this guide
• Introduction
• Essay structure
• Additional resources

The last section of an academic essay is the conclusion . The conclusion should reaffirm your answer to the question, and briefly summarise key arguments.  It does not include any new points or new information. A conclusion has three sections. First, repeat the thesis statement. It won’t use the exact same words as in your introduction, but it will repeat the point: your overall answer to the question. Then set out your general conclusions , and a short explanation of why they are important.

Finally, draw together the question , the evidence in the essay body, and the conclusion. This way the reader knows that you have understood and answered the question. This part needs to be clear and concise.

“Pay adequate attention to the conclusion.” Kathleen McMillan & Jonathan Weyers,  How to Write Essays & Assignments

Conclusions are often overlooked, cursory and written last minute. If this sounds familiar then it's time to change and give your conclusions some much needed attention. Your conclusion is the whole point of your essay. All the other parts of the essay should have been leading your reader on an inevitable journey towards your conclusion. So make it count and finish your essay in style.

Know where you are going

Too many students focus their essays on content rather than argument. This means they pay too much attention to the main body without considering where it is leading. It can be a good idea to write a draft conclusion before  you write your main body. It is a lot easier to plan a journey when you know your destination! 

It should only be a draft however, as quite often the writing process itself can help you develop your argument and you may feel your conclusion needs adapting accordingly.

What it should include

A great conclusion should include:

A clear link back to the question . This is usually the first thing you do in a conclusion and it shows that you have (hopefully) answered it.

A sentence or two that summarise(s) your main argument but in a bit more detail than you gave in your introduction.

A series of supporting sentences that basically reiterate the main point of each of your paragraphs but show how they relate to each other and lead you to the position you have taken. Constantly ask yourself "So what?" "Why should anyone care?" and answer these questions for each of the points you make in your conclusion.

A final sentence that states why your ideas are important to the wider subject area . Where the introduction goes from general to specific, the conclusion needs to go from specific back out to general.

What it should not  include

Try to avoid including the following in your conclusion. Remember your conclusion should be entirely predictable. The reader wants no surprises.

Any new ideas . If an idea is worth including, put it in the main body. You do not need to include citations in your conclusion if you have already used them earlier and are just reiterating your point.

A change of style i.e. being more emotional or sentimental than the rest of the essay. Keep it straightforward, explanatory and clear.

Overused phrases like: “in conclusion”; “in summary”; “as shown in this essay”. Consign these to the rubbish bin!

Here are some alternatives, there are many more:

• The x main points presented here emphasise the importance of...
• The [insert something relevant] outlined above indicate that ...
• By showing the connections between x, y and z, it has been argued here that ...

Maximise marks

Remember, your conclusion is the last thing your reader (marker!) will read. Spending a little care on it will leave her/him absolutely sure that you have answered the question and you will definitely receive a higher mark than if your conclusion was a quickly written afterthought.

Your conclusion should be around 10% of your word count. There is never a situation where sacrificing words in your conclusion will benefit your essay.

17 Essay Conclusion Examples (Copy and Paste)

Essay conclusions are not just extra filler. They are important because they tie together your arguments, then give you the chance to forcefully drive your point home.

I created the 5 Cs conclusion method to help you write essay conclusions:

I’ve previously produced the video below on how to write a conclusion that goes over the above image.

The video follows the 5 C’s method ( you can read about it in this post ), which doesn’t perfectly match each of the below copy-and-paste conclusion examples, but the principles are similar, and can help you to write your own strong conclusion:

💡 New! Try this AI Prompt to Generate a Sample 5Cs Conclusion This is my essay: [INSERT ESSAY WITHOUT THE CONCLUSION]. I want you to write a conclusion for this essay. In the first sentence of the conclusion, return to a statement I made in the introduction. In the second sentence, reiterate the thesis statement I have used. In the third sentence, clarify how my final position is relevant to the Essay Question, which is [ESSAY QUESTION]. In the fourth sentence, explain who should be interested in my findings. In the fifth sentence, end by noting in one final, engaging sentence why this topic is of such importance.

Remember: The prompt can help you generate samples but you can’t submit AI text for assessment. Make sure you write your conclusion in your own words.

How to Write a Conclusion

Writing the introduction and body of a paper is a big accomplishment. Now you need to write your conclusion. Writing a conclusion can feel difficult, but it's easier if you plan ahead. First, format your conclusion by revisiting your thesis, summarizing your arguments, and making a final statement. Then, re-read and revise your conclusion to make it effective.

• Let’s say your thesis reads, “Allowing students to visit the library during lunch improves campus life and supports academic achievement because it encourages reading, allows students to start assignments early, and provides a refuge for students who eat alone.”
• You might restate it as, “Evidence shows students who have access to their school’s library during lunch check out more books and are more likely to complete their homework; additionally, students aren’t forced to eat alone.”

• You might write, “According to data, students checked out more books when they were allowed to visit their library during lunch, used that time to do research and ask for help with homework, and reported feeling less alone at lunch time. This shows that opening up the library during lunch can improve student life and academic performance."
• If you’re writing an argument essay, address the opposing argument, as well. You might write, “Although administrators worry that students will walk the halls instead of going to the library, schools that allow students into the library during lunch reported less behavioral issues during lunch than schools that don’t allow students in the library. Data show that students were spending that time checking out more books and working on homework assignments.” [3] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source

• Call your reader to action . For example, “By working with school administrators, Greenlawn ISD can increase academic achievement by letting students use the library during lunch.”
• End with a warning . You might write, “If students aren’t allowed to use the library during lunch, they are missing out on a valuable learning opportunity they’ll never get back.”
• Evoke an image . Write, “Next year, students at Greenlawn could be gathered around a table in the library reading or broadening their minds.”
• Compare your topic to something universal to help your reader relate . You might write, “Everyone knows how stressful it is to have a planner full of assignments, so having extra time to work on them during lunch would be a great relief to many students.”
• Show why the issue is significant. Write, "Giving students more time to spend in the library will help them become more comfortable spending time there, which also helps the library's mission."
• Predict what would happen if your ideas are implemented . Say, “Next year, students at Greenlawn could increase their academic achievements, but results will only happen if they can use the library during lunch.”
• End with a compelling quote . For instance, "As author Roald Dahl once said, 'If you are going to get anywhere in life, you have to read a lot of books.'"

• You could also ask your instructor if you can see an example of a well-written conclusion to give you an idea about what they expect you to write.

• If you want to use an introductory phrase, use a stronger one like “based on the evidence” or “ultimately.” You might also begin your first sentence with a word like “although,” “while,” or “since.” [6] X Trustworthy Source University of North Carolina Writing Center UNC's on-campus and online instructional service that provides assistance to students, faculty, and others during the writing process Go to source
• Additionally, avoid “to conclude,” “in summary,” or “in closing.”

• For example, you may have opened your introduction with an anecdote, quote, or image. Bring it back up in your conclusion. Similarly, if you opened with a rhetorical question, you might offer a potential answer in your conclusion.

• For example, you wouldn’t want to end your essay about allowing students to use the library during lunch by stating, “As the evidence shows, using the library at lunch is a great way to improve student performance because they are more likely to do their homework. On a survey, students reported using the library to do research, ask homework questions, and finish their assignments early.” This leaves out your points about students reading more and having a place to spend their lunch period if they don’t like eating in the cafeteria.

• If you have introduced something you think is really important for your paper, go back through the body paragraphs and look for somewhere to add it. It’s better to leave it out of the paper than to include it in the conclusion.

• If something doesn’t make sense or your conclusion seems incomplete, revise your conclusion so that your ideas are clear.
• It’s helpful to read your entire paper as a whole to make sure it all comes together.

Conclusions

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

This resource outlines the generally accepted structure for introductions, body paragraphs, and conclusions in an academic argument paper. Keep in mind that this resource contains guidelines and not strict rules about organization. Your structure needs to be flexible enough to meet the requirements of your purpose and audience.

Conclusions wrap up what you have been discussing in your paper. After moving from general to specific information in the introduction and body paragraphs, your conclusion should begin pulling back into more general information that restates the main points of your argument. Conclusions may also call for action or overview future possible research. The following outline may help you conclude your paper:

In a general way,

• Restate your topic and why it is important,
• Restate your thesis/claim,
• Address opposing viewpoints and explain why readers should align with your position,
• Call for action or overview future research possibilities.

Remember that once you accomplish these tasks, unless otherwise directed by your instructor, you are finished. Done. Complete. Don't try to bring in new points or end with a whiz bang(!) conclusion or try to solve world hunger in the final sentence of your conclusion. Simplicity is best for a clear, convincing message.

The preacher's maxim is one of the most effective formulas to follow for argument papers:

Tell what you're going to tell them (introduction).

Tell them (body).

Tell them what you told them (conclusion).

Essay Writing as a Tool for Self-Reflection and Personal Growth

T raditionally, essay writing was seen as an academic exercise, but not anymore. An essay is a piece of writing that is written to convince someone of something or to inform the reader about a particular topic. As students write essays, they introspect and learn at the same time. They understand that the essay writing process is not just about forming arguments or persuading readers; it is also a powerful mechanism for self-discovery. By articulating thoughts and emotions on paper, you better understand your perspectives and experiences.

Writing essays encourages writers to confront their inner thoughts, beliefs, and values. This confrontation is not always comfortable. Many of you already know this fact. However, the process is invariably enlightening. Through the structured thinking that essay writing demands, individuals can explore and organize their thoughts in ways other forms of reflection might not allow.

This process often leads to a deeper understanding of oneself. And not just that; it’s crucial for personal development. A 2019 study found that expressive writing has been shown to improve emotional and physiological health. Besides, the iterative nature of writing, that is, drafting, revising, and refining, mirrors the iterative process of personal growth. What does this premise mean? Well, self-awareness leads to new insights, which then lead to further questions and exploration.

But not everyone can write a compelling essay. Even the most talented writers can struggle with some topics. However, did you know that professional essay writers can help you with your paper? These experts specialize in specific disciplines and can provide subject-specific, content-savvy papers that surpass your expectations. And if you are not very conversant with writing an essay, rest assured that they will convince you or be adequately informed.

All in all, an essay must include several important components to make it flow logically. Its main parts (or sections) are the introduction, body, and conclusion. In a standard short essay, five paragraphs can provide the reader with enough information in a short space. However, more than five paragraphs must be present for a research paper or dissertation to not overwhelm the reader with too much information in one section.

Moreover, essay writing is a tool for emotional intelligence. Yes, you read that right. It offers a safe space for writers to express and manage their feelings. You often find clarity and a sense of relief as you translate complex emotions into words. The reflective practice of writing helps individuals cope with past experiences and prepares them for future challenges by building resilience and adaptability. Thus, the benefits of essay writing are vast. The following is a list of how essay writing is a tool for self-reflection and personal growth.

How Essay Writing is a Tool for Self-Reflection and Personal Growth

Essay writing can be the bridge between internal exploration and external expression. But how so? This practice allows individuals to explore their thoughts and feelings, translating introspection into tangible form. As you articulate your experiences and viewpoints, you engage in a dialogue with yourself, which fosters emotional growth.

• Enhances self-awareness : As previously mentioned, writing essays requires self-examination, which can significantly increase self-awareness. When you choose topics that resonate personally, you’re prompted to reflect on your beliefs, behaviors, and motivations. This process helps you understand yourself, highlights areas for improvement, and reaffirms your core values.
• Cultivates empathy : A recent study on the importance of writing practice showed statistically significant increases in various aspects of empathy, such as reasoning, including multiple perspectives, expressing emotion, and proposals for action, and statistically significant increases in empathy as a latent construct. When crafting essays, writers often explore different perspectives and consider alternative viewpoints. This exercise can cultivate empathy, as it encourages them to understand and articulate feelings and situations from other people’s points of view.
• Promotes critical thinking : Like any other form of academic writing, essay writing compels students to think critically about their experiences and the world around them. But the question is: how so? It involves analyzing one’s thoughts and questioning existing beliefs. This process can lead to new insights and a more informed perspective. Besides, critical examination helps you develop a more mature understanding of complex situations.
• Improves communication skills : Strong writing skills contribute to effective communication. Regular essay writing hones one’s ability to convey thoughts clearly and effectively. In fact, this point is scientifically proven. Essay writing helps individuals learn how to express their ideas in a structured, coherent, and persuasive manner.
• Facilitates emotional healing : We cannot emphasize this point enough. Writing about personal experiences, especially traumatic ones, can be therapeutic. Yes, you read that right. Putting emotions into words helps people process and make sense of their experiences.
• Encourages mindfulness : Writing promotes mindfulness, or present-moment awareness, and its associated qualities of calm/relaxation, nonjudgment, and intentionality. The focus required in essay writing can promote mindfulness. By concentrating on the present moment and the task of articulating thoughts, you can experience a calming effect, reducing anxiety and enhancing your overall mental health.
• Strengthens problem-solving abilities : Students’ problem-solving skill is heavily influenced by the learning process in the classroom. Essays often explore solutions to problems. They can involve real-world problems that trigger learning and optimize the power of problems to incorporate key learning processes. This aspect requires writers to think strategically about possible solutions, weighing pros and cons and considering outcomes.

Improve Your Writing Skills

For students, most of your assessments are done through writing. You will be asked to write essays for assignments and exams in most study areas. Accordingly, knowing how to write well is suitable for your grades. But there are other personal benefits as well. It can be a tool for personal growth and self-reflection. Essay writing can transform your understanding of yourself and the world around you.

How to make a map of smell

We can split light by a prism, sounds by tones, but surely the world of odour is too complex and personal strangely, no.

by Jason Castro   + BIO

What is the distance between the scent of a rose and the odour of camphor? Are floral smells perpendicular to smoky ones? Is the geometry of ‘odour space’ Euclidean, following the rules about lines, shapes and angles that decorate countless high-school chalkboards? To many, these will seem like either unserious questions or, less charitably, meaningless ones. Geometry is logic made visible, after all; the business of drawing unassailable conclusions from clearly stated axioms. And odour is, let’s be honest, a bit too vague and vaporous for any of that. The folksy idea of smell as the blunted and structureless sense is at least as old as Plato, and I have to confess that, even as an olfactory researcher, I sometimes feel like I’m studying the Pluto of the sensory systems – a shadowy, out-there iceball on a weird orbit.

In recent years, however, things have changed dramatically, and understanding what one might call ‘the geometry of smell’ is a field that now enlists task forces of neuroscientists working together with mathematically trained theorists and artificial intelligence (AI) experts. While we’re notoriously bad at intuiting how our minds organise phenomena like colours and smells, machines offer a potential route for outsourcing introspection, and doing it with rigour. They can be trained to mimic human performance on perceptual tasks, and they make available the internal representations they use to do this – the abstract spaces and coordinate frames in which the ineffable stuff of thought lives.

The recent publication of an unprecedentedly comprehensive and accurate ‘odour map’ in the journal Science is a declaration of this new paradigm for smell. In the same way that a map of the United States tells you that Buffalo is a bit closer to Detroit than to Boston, the odour map can tell you that the smell of lily is closer to grape than it is to cabbage. That much may seem obvious, but the real magic comes from the fact that any arbitrary chemical’s precise location on the odour map can be calculated. From having only a few facts on hand about a chemical, we can compute that it smells, say, 13 per cent closer to lily than to grape. By analogy, it would be something like having a formula that takes in information about an unknown city’s population size and soil composition, and spits out, correctly, the exact longitude and latitude of Philadelphia.

A map like this isn’t just an accurate, laboriously assembled catalogue of relative locations and perceptual similarities. It’s something much more powerful: a set of derived rules for calculating which odour goes where. Knowing these rules, you can apply them not just to a small handful of chemicals, but to the entire world of odorous chemicals. You can see where the most densely populated areas are, and where the ‘state lines’ are in the world of smells. This is a prospect that dazzles the world’s perfumers and gourmands, and anyone else interested in the notoriously difficult and fickle task of predicting how something will smell from its chemical properties.

But, even more than this, it also raises intriguing philosophical questions about what our noses even think chemicals are , and what it means to measure their similarity. What is it about the world that our noses are ‘mapping’, in other words, when they put lily close to grape? Are they latching on to some single molecular property like a chemical’s weight or size? Are they calculating some kind of average fingerprint across a variety of such properties? Or are they doing something different altogether, like locating molecules in a space of common metabolic reactions?

Interestingly, the last of these seems to be more the case. The perceptual yardstick our brains use to measure, organise and compare smells may ultimately have less to do with what a chemist could discover from running a sample, and more to do with our deep relational histories with the world. Our noses may turn out to be geometers not of the world’s fixed and invariant properties , but of its evolved and Earthly processes .

There is something poetic in the idea that, in order to crack the ‘ancient sense’, the crude, most scientifically incorrigible sense, we’ve had to wait for machine intelligence. This is in contrast with the other sensory modalities, which began to share their secrets in the 17th century to wizard-like seers bearing prisms and tuning forks.

T he basic investigative template for ‘geometrising’ the senses was developed by Isaac Newton in the late 1600s. In his iconic experiments in optics, performed in his Cambridge parlour, he uncovered a relationship between the colour of light and its refrangibility – the degree to which it was bent by a simple prism. The mere description of this fact would have ranked among the most important scientific discoveries ever, but Newton went a step further, and fit his observations to a geometric model. Wrapping the seven primary colours of the visible spectrum along the circumference of a circle (see figure below), he produced the first ‘chromaticity diagram’ – a forerunner of the colour wheels that we use to organise our thinking about colours and their mixtures.

The circle, for Newton, was not just some poetic flourish, but a commitment to a very particular way of encoding colour’s properties. It was an invitation to pull out our protractors and rulers, and make calculations about how colours relate to one another, and combine into mixtures. The components of a three-part mixture of fully saturated red, yellow and green, for example, would be represented as the three vertices of a triangle, with each vertex pinned on the colour circle’s circumference at the appropriately labelled point. The centre of mass of this triangle is a single point in the circle’s interior, and specifies the hue and saturation of the resultant mixture. In the case of mixing all seven primary colours to an equal degree, the centre of mass of the seven-pointed figure would be at the exact centre of the circle, which Newton designated as white.

There is of course a lot more to colour vision than what Newton described in his Opticks (1704), and even his contemporaries noted flaws and shortcomings in his model. Nevertheless, his achievement still encapsulates the ambition of the classical paradigm for sensory mapping. It seeks a mathematical correspondence between measurable and intrinsic properties of the natural world (like light’s refrangibility, which we now attribute to wavelength), and phenomenological qualities of mind (like colour, pitch and smell). There is something like a Pythagorean, the-world-is-mathematics mysticism to the endeavour.

The basic logic of pitch perception was also cracked similarly, with simple tools like tuning forks and spherical ‘resonators’ used to produce pure tones of a single frequency, from which rules about consonant pitch combination could be derived. Pitch perception as a whole is fantastically complex but, in broad strokes, our entire auditory system – from the tiny coiled-up cochlea of our inner ear, to the auditory portions of our sensory cortex – is built on the basic principle of organising low, middle and high tones like the keys of a piano. Striking neighbouring notes on a piano will also ‘strike’ neighbouring neurons in your brain.

S mell could never be parsed with a tool as fundamental as a tuning fork, and it never got its Newton, but it was not for a lack of people trying to follow his lead as a geometer of the senses. The idea that there might exist a small number of ‘odour primaries’ that, by analogy to the prismatic colours, organised the world of smells has occurred to many, and the search for these continued in earnest well into the 20th century.

An early and influential classification scheme for odours by the famed botanist and taxonomist Carl Linnaeus, in 1756, included seven types: aromatic, fragrant, ambrosial (musky), alliaceous (garlic), hircine (goaty), repulsive, and nauseous. A contemporary of Linnaeus’s, Albrecht von Haller, was a bit stingier with his adjectives, and proposed a more austere scheme of three basic odour types: sweet/ambrosiac, stench, and intermediate. One senses that ‘intermediate’ is doing a lot of work here, but perhaps Haller adopted the idea out of a conviction that all odours could be squeezed onto a line, and organised along a single axis. If these early odour taxonomies sound like they have a rather ad-hoc feel to them, it’s because they were the fruit of introspection rather than careful data collection and measurement. Basically, these guys were winging it.

In fairness though, it wasn’t (and honestly still isn’t) really obvious how to not wing it. With all due deference to one of history’s geniuses, Newton had it easy. He could create essentially any visible colour at will by rotating a few pieces of polished glass in a slit of sunlight. The stimulus just showed up, unasked for, when the sun rose, and in a form that was virtually readymade for scientific interrogation. Odours are far less workable. If Newton had wanted to study odour, he would have had to start by grabbing some plants, maybe some spoiled food, a crust of bread, a swab from his chamber pot if he was feeling audacious and naughty. This doesn’t exactly scream ‘Newtonian’. The critical missing abstraction of ‘the chemical compound’ as the basic property-bearing token of smell was still far off, as were the techniques for synthesising pure chemicals for testing purposes.

Henning proposed an odour prism that organised smells into flowery, fruity, resinous, spicy, burnt, and foul

But even if these impediments could have been, miraculously, dealt with, there are additional, deeper complications that make the problem of smell harder than the problem of colour. These boil down to the fact that chemicals aren’t smoothly graded variations of a single underlying phenomenon, like light is. Rather, they’re collections of the world’s particulate stuff. And, ultimately, there’s just a lot of stuff and kinds of stuff out there, making it highly unlikely that some single chemical property – a molecular analogue of light’s refrangibility – will capture all the meaningful variability in the wild and woolly world of chemicals. If there was a map from chemical features to odour qualities, it would have to involve something more complicated than a circle, with more places – in fact, more dimensions – to distribute the chemicals.

Perhaps something like a prism would do? If we take it as a loose geometric metaphor, it seems to have some virtues over the circle, and is reaching in the right direction. The prism has faces and facets on different planes, which could be used for organising molecules according to diverse criteria like atom type or chemical group. Its sharp points suggest areas of aggregation and separation in chemical space that emphasise odour’s discrete categories versus light’s continua.

For the German scholar of smell Hans Henning, this was more than just metaphor. In his book Der Geruch (‘Smell’) (1916), he proposed the idea of an abstract odour prism that organised the world of smells, with its six pointy vertices corresponding to what he considered to be the olfactory primaries: flowery, fruity, resinous, spicy, burnt, and foul. Even though there had been considerable developments that allowed for better quantification of how humans perceive odour, and better physical descriptions of odour stimuli, the field was not ready for a proposal like Henning’s. He was, by all accounts, one of those scientists, described by the US neurobiologist Gordon Shepherd, ‘whose imaginations cannot resist the temptation to put together an underconstrained theory.’ Also, Henning didn’t do himself any favours in forcefully promoting his work, and swiping at influential icons of the field like the Dutch scientist Hendrik Zwaardemaker, who had pioneered the use of olfactometers – steam-punky contraptions of valves and tubing that delivered controlled doses of odour. An early reviewer who otherwise spoke very positively of Henning’s book still felt compelled to refer to him, on the record, as ‘a ruthless – in fact very uncivil – iconoclast.’ Henning had bulldozed into the discussion a strongly geometric conception of odour that was inspired and influential but, ultimately, a house of cards.

To Henning’s credit, despite his theory’s shakiness, it was specific enough to be testable, and the invitation was taken up by several, including the psychologist Malcolm Macdonald. In a comprehensive and devastating critique from 1922 that ended with a long section entitled ‘Logical and Factual Inadequacies of Henning’s Theory’, Macdonald investigated whether there was really a prism behind things in the world of smells. Using judgments of relative odour similarity as a proxy for distance (where ‘similar smelling’ = ‘close’), he performed critical perceptual reality-checks, like asking whether chemicals taken from opposite ends of the long prism diagonal smelled the least similar. When you say that odour is a prism, you should expect that your colleagues will pull out their calculators and check.

‘Odour maps’ gave a bird’s eye view of how the human nose organises the world of chemicals

What, exactly, did Henning get wrong? The question is a bit tongue-in-cheek, because it’s not clear that there’s anything he got right. Still, if we want to be charitable, we might say he was seduced by a Lego-like view of molecules that organic chemists were developing at the time. They saw a modular system in which organic molecules were assembled from a small library of so-called functional groups, resulting in motifs of a few atoms arranged in stereotyped ways. In addition to haunting the dreams of hopeful premeds everywhere, these functional groups were thought to confer a molecule’s specific properties, and define its basic reactivity. In Henning’s view, it was perfectly sensible that the same functional groups should also confer the primary odours he had identified. Indeed, there is something enticing about the idea that the chemist’s alphabet for organic molecules might also be the nose’s alphabet for smell. Ultimately, however, nature chose not to oblige. Few olfactory neuroscientists would claim that functional group is unimportant for determining odour quality, but it is clearly not the whole story.

In modern machine-learning parlance, we might say that Henning didn’t have a rich enough feature set for representing smells. In committing to functional group as his basic smell alphabet, he implicitly adopted a specific idea of what a molecule fundamentally is, and discarded other potentially useful features that could serve as the grist for odour prediction. A molecule, after all, isn’t just a list of the Lego blocks from which it’s made. It’s also a springy little thing that spins and vibrates, and chemists can ring it like a tiny molecular bell to listen for clues about its structure. It is also a list of descriptive attributes like ‘strongly acidic’, or ‘non-polar’ (having symmetrically distributed charges). And it’s also a lump of just so much stuff, maybe a bit bulkier here, and more stretched-out there.

Instead of doing what Henning did, seizing on one characteristic in advance, the best way forward is obviously an agnostic mindset where the data does the talking. Instead of making fantastically wrong guesses about which chemical features determined odour quality, why not winnow them down from a massive list of all conceivable features?

That’s the approach in studies pioneered by the US scholar Susan Schiffman and others in the 1970s and ’80s. The basic idea was to take a set of a few dozen odorous molecules and create a map summarising their relative perceptual similarities. Similar to how one could create a rough map of the US from a table of all (of the many!) between-city distances, these ‘odour maps’ gave a bird’s eye view of how the human nose organises the world of chemicals. With this perceptual map in hand, the question then turned to chemistry: what is it about molecules that assigns them to some particular portion of the perceptual map? To get at this, Schiffman and others used a range of ‘dimensionality reduction’ techniques to see which chemical features – of the many hundreds potentially available – were most effective at recapitulating the map. These approaches generated significant interest for a time, but they too were unable to solve the problem and went dormant for decades – until the age of AI.

I t was in 2017 that data sets were finally democratised enough for machine learning to help scientists widen the search. An important milestone that year was the DREAM challenge to see who might solve the odour map using AI. Published in Science , the winning models were endorsed by the community as potential inroads – suggesting that handing our model-making to the custody of the machines was the right intellectual move.

The best models, the so-called ‘random forests’, used AI to aggregate a host of models. The result could be baroque and inscrutable systems of rules for performing prediction tasks. They can get the right answer, but it’s often by finding lengthy and complex rubrics along the lines of: ‘If the molecular weight is > X, and the number of carbons is > Y, and the Moreau-Broto autocorrelation of lag 7 is < Z, and…, and…, then the molecule will smell like rose.’

It’s of course possible that odour categorisation is handled by similar ‘brute’ computations in the brain, but one is left with the nagging question: is that really how nature solved it? Not through the economy of Occam’s razor but in the thicket of Occam’s forest? Where’s the deep principle? The basic organising axes? The geometric insight? An important and often-asked question about these kinds of ‘data-driven’ models is whether their success at prediction actually indicates understanding or, at least, the kind of understanding that science has historically prized and glorified through tidy parables of discovery like ‘Newton and the prism’.

One way forward is to give up on the idea of an organised odour space whose curves and contours cleanly track some yet-to-be revealed chemical properties. After all, if ‘stinky feet’ and ‘gourmet cheese’ can be two valid descriptions of the same physical object, perhaps odour qualities are just too labile and individual to really serve as the targets for prediction. Perhaps they reflect more what we’ve learned from living in the messy world than anything intrinsic to it, encoding our idiosyncratic experiences with, and predilections for, feet and cheeses. Perhaps there is even something romantic and worth defending here in the idea of a sense that, decades into the age of mass digitisation, remains stubbornly phantom-like and evanescent, unmeasurable, and fundamentally unavailable for capture by geometric concepts.

Scientists are training, tuning and tweaking million-parameter models that ingest digitised molecule after digitised molecule

Or we go in the opposite direction. Hit the problem with even more data and more computing power. This was the big bet made by Osmo, a startup based in Cambridge, Massachusetts that began several years ago as the digital olfaction group at Google Brain, and which now has several dozen neuroscientists, chemists and computer scientists on its staff.

Osmo is the brainchild of Alex Wiltschko, a Harvard-trained neurobiologist who made his mark in grad school developing pioneering computer-vision systems for analysing animal behaviour. After growing up in small-town Texas, where, he drily notes ‘neither computers nor perfume were popular’, his twin passions for aromas and algorithms eventually landed him at the helm of a company that is ‘giving computers a sense of smell’.

This is about as far as one can get from Newton investigating the senses in his lonely parlour, sketching models on vellum with a quill pen. Instead, these scientists are collaborating to develop dense code repositories, training, tuning and tweaking million-parameter models that ingest digitised molecule after digitised molecule under the mandate This one smells like rose, this one smells like grass, figure out how to make that happen. The chemicals are not given to the model as lists of predetermined molecular properties that are served up to some homunculus chemist in the nose. Instead, they’re represented as skeletal and stripped-down graphs that capture only basic information about atom identities and their connectivity. The model is not trying to find what aspects of known chemistry are important for smell. It’s trying to discover whether chemical principles we haven’t yet thought of may hold the key for smell.

The Osmo model is a type of graphical ‘deep net’ that’s loosely inspired by the successive processing stages of the brain’s sensory systems. The analogy isn’t exact, but it’s similar to how your brain captures raw information from the world and passes it downstream to units that will ultimately have something useful or actionable to say about the inputs: ‘It’s a cat!’ or ‘Smells awful!’ The output units are the doers and the deciders whose performance can be evaluated (‘Nope, it’s actually a dog’ or ‘Yup, that chemical really does smell awful’), but many important insights are found in the intermediate, or ‘hidden’, network layers, too. These can be thought of as a transformational space that squeezes and warps raw sensory inputs into sensory judgments. The connections between units that define these transformations are learned gradually and incrementally by an AI system as it continually iterates and self-adjusts based on how well it mimics human judgments. By peeking at these intermediate layers, we can get the insights of a latterday, AI-supercharged Newton of smell. They tell us how we might think about the space that chemicals live in. Or at least, as our nose sees it.

S o how do we get from the transformations within the Osmo net to a literal geometry? The geometry at hand is not a circle, or a prism, or any kind of simple archetypal shape. Instead, it’s more like a world of craggy chemical continents, each demarcating a conspicuous aspect of human ecology, each seeming to invite a set of actions or appetites. There is, for example, a continent of ‘fermentation’, a ‘green’ continent, a land of the ‘meaty and savoury’. The key notion is that, in this space, two chemicals are rendered as close together and similar-smelling not because they necessarily share intrinsic structural features, but because they share ecological roles and have a close and contingent relationship out in the wild, as it were.

The Newtonian story of colour space is about how human perception latches on to the world’s universal and impersonal attributes (think about light’s wavelength and refrangibility). But the developing story of smell is about how our noses have decoded the world as it manifests locally, relationally and idiosyncratically on our planet. Odour space, in other words, is framed in human-centred coordinates, reflecting our histories as foragers and hunters in a world that blooms and withers, with matter that ripens and decays. It is a geometry that invests matter with its meanings and possibilities for us .

But it’s not just some loosely poetic space. Tapping the Osmo model, one can compute distances and angles here, predict which chemical will smell exactly halfway in-between musk and carvone, examine whether a collection of chemicals should trace out a smooth or squiggly path in odour-perceptual space. Moreover, the Osmo model does this demonstrably better than other attempts, suggesting that the way it’s measuring distances between chemicals may point to a deep principle of odour processing.

To smell something is to understand the neighbourhood it lives in

Interestingly, distances computed on the map correlate strongly with what has been termed ‘metabolic distance’ – roughly, how reachable one chemical is from another through common metabolic pathways. If nature can easily move from chemical A to chemical B through a small number of fermentation reactions, say, chances are your nose will find A and B to smell alike, even if they lack obvious structural similarities. The important corollary is that molecules with striking structural similarities needn’t smell alike (though, of course, they often will). A and B might hypothetically differ by only one double bond, but if it’s a very expensive double bond to form or break, requiring a large number of synthesis steps and chemical pirouettes, then the compounds will smell different to us. What the nose seems to know is not the static world of chemicals, but the movements that nature makes through it.

A philosopher would say that your nose appears to be an empiricist – it classifies and categorises chemicals on the basis of relationships that must be learned from the world either over evolutionary timescales or over an individual’s lifetime. A mathematician, following up, would say that what is learned is the abstract, high-dimensional manifold that tracks the world’s chemical relationships – its partitioning into the branches, cycles and pathways that shuttle around the world’s carbon. To smell something is to locate it on this manifold, to understand the neighbourhood it lives in.

These are still early days for theorising about the structure of odour space, but several investigators have put forward the idea that the space is non-Euclidean, meaning that it’s a far cry from the ‘intuitive’ geometry of secondary school, where the angles of a triangle always add up to 180 degrees. Instead, odour space may have an intrinsic curvature to it (like a potato chip, according to one theorist), driven by the fact that distances in odour space are defined less like the physical distance between two people, and more like their social distance.

Amazingly, Macdonald, the critic of Henning described above, had an intuition of this back in 1922, when he suggested modifications to the odour prism that amounted to replacing it with a ‘hollow hyper-solid with solid tetrahedrons as its sides’. This is difficult to visualise but, basically, it is a higher-dimensional prism that gives odours more space in which they can distribute themselves. ‘There is no reason why mental continua should occur only under Euclidian [sic] limitations,’ he noted. Perhaps smell has been the last standing sensory mystery because its mathematics has proven to be the most esoteric.

Gig workers are writing essays for AI to learn from

• Companies are hiring highly educated gig workers to write training content for AI models .
• The shift toward more sophisticated trainers comes as tech giants scramble for new data sources.
• AI could run out of data to learn from by 2026, one research institute has warned. 

As artificial intelligence models run out of data to train themselves on, AI companies are increasingly turning to actual humans to write training content.

For years, companies have used gig workers to help train AI models on simple tasks like photo identification , data annotation, and labelling. But the rapidly advancing technology now requires more advanced people to train it.

Companies such as Scale AI and Surge AI are hiring part-timers with graduate degrees to write essays and creative prompts for the bots to gobble up, The New York Times reported . Scale AI, for example, posted a job last year looking for people with Master's degrees or PhDs, who are fluent in either English, Hindi, or Japanese and have professional writing experience in fields like poetry, journalism, and publishing.

Their mission? To help AI bots "become better writers," Scale AI wrote in the posting.

And an army of workers are needed to do this kind of work. Scale AI has as many as tens of thousands of contractors working on its platform at a time, per the Times.

"What really makes the A.I. useful to its users is the human layer of data, and that really needs to be done by smart humans and skilled humans and humans with a particular degree of expertise and a creative bent," Willow Primack, the vice president of data operations at Scale AI, told the New York Times. "We have been focusing on contractors, particularly within North America, as a result."

The shift toward more sophisticated gig trainers comes as tech giants scramble to find new data to train their technology on. That's because the programs learn so incredibly fast that they're already running out of available resources to learn from. The vast trove of online information — everything from scientific papers to news articles to Wikipedia pages — is drying up.

Epoch, an AI research institute, has warned that AI could run out of data by 2026.

So, companies are finding more and more creative ways to make sure their systems never stop learning. Google has considered accessing its customers' data in Google Docs , Sheets, and Slides while Meta even thought about buying publishing house Simon & Schuster to harvest its book collection, Business Insider previously reported.
