Compare and contrast two books

Learning Objectives

• Understand the common structures and uses of comparison and contrast writing.

One of the most common types of writing (and thinking) is comparison writing. When considering the pros and cons of a new purchase or decision, for instance, many of us use comparisons to existing models. Students are also often asked to compare something they’re reading with another similar text. Reviews of popular media also often compare or contrast: consider the line, “Her best work since…” which offers a direct comparison with a previous performance.

Comparison and contrast essays, however, often get the reputation of being boring or sounding automatic. While the form is useful, it is also plain, and it can inspire uninspiring writing. This chapter aims to help you understand when comparison is appropriate, the terms that we use to talk about it, how to structure it, and then how to use those structures in a meaningful and creative way across media.

What is Comparison and Contrast Writing?

Comparison and Contrast writing is used to show a reader the similarities and/or differences between two subjects. Comparison writing focuses on similarities (ways things are alike), while contrast writing focuses on differences or ways they are not alike.

In order to do this, the subjects chosen have to be related or share at least some characteristics. You may have heard that it’s impossible to compare apples and oranges. This isn’t true, of course: an apple can easily be compared to an orange, since they both share many characteristics (both fruit, both vaguely round, both on sale at the store, both considered nutritious, etc.). However, some items would be very difficult to compare: writing a short essay comparing a Fuji apple to an Apple MacBook might result in no meaningful similarities. That paper would, likely, be a waste of a reader’s (and writer’s) time.

Meaningful comparison, however, can enlighten an audience toward unknown similarities or differences between subjects. The more informative or surprising a comparative is, the more likely an audience is to be engaged. For example, writing a paper that compares two well-known superheroes and discusses their similarities might not be that interesting. Showing how alike a superhero and a villain are, though, might subvert the audience’s expectation (that heroes and villains have nothing in common), which could lead to a more interesting paper.

Some assignments will specifically ask for a comparison or a contrast. Others may want you to incorporate both. Read carefully to find what’s most appropriate.

Examples

Here are a few example essay prompts that might lead to comparison/contrast writing:

• What are the major similarities and differences between the Honda Hobbit and the Ford Frodo? (Asks for compare/contrast)
• Discuss the leadership styles of Ulysses S. Grant and Robert E. Lee. (Could be comparing/contrasting)
• How do recent behaviors around social media compare to the early introduction of the telegraph? (Asks for comparison, but may also want contrast)

Objective versus Subjective Comparison

The purpose of a comparison/contrast paper seems obvious – we’re talking about similarities/differences between two subjects to better inform our readers. However, there’s sometimes a secondary purpose to these papers: Comparison papers are often written to convince a reader that one subject is superior to the other.

Examples

• Compare and contrast the SmartPhone A to the new SmartPhone AX. Which is better for a student?
• Compare two presidents from the 19th century. Which one practiced better military leadership?

A subjective comparison includes factual information about both subjects but may also include the writer’s opinions. It may also work to convince a reader to consider one subject to be better than the other. Subjective comparisons also include the writer’s evaluation of the information. For instance, a writer will present facts about SmartPhone A, analysis of these facts, and their own opinion: [Fact] SmartPhone A is less expensive than SmartPhone AX by nearly $100, which [Analysis] makes it a better buy for most students. However, I’d [opinion] easily pay $100 to get a phone as sleek as the AX.

In addition, a subjective comparison will lead toward a conclusion at the end, deciding between the subjects being compared. This means that subjective comparison papers often function as argumentative writing, though they spend a good deal of time with the second subject.

By contrast, an objective comparison paper does not automatically seek to decide between options when it begins. It may list the categories for comparison that the subjects will be judged against, but it will build toward its conclusion through presenting facts, evidence, and analysis, not through subjective evaluation. An objective comparison is an informative paper, not an argumentative paper. Nevertheless, at the end, it may draw the conclusion that one side is better than the other, within the set of criteria established.

What’s that all mean? Here’s an example: An objective comparison of two types of smartphone would include factual information about both phones, like price, weight, available apps, camera resolution, and maybe a roundup of how they’ve been reviewed by credible sources. The author might find that college students have said the three most important things they look for in a phone are price, plans available, and apps available, so at the end of the piece, they could say, Based on the information presented here, the SmartPhone A would be a better buy for the average college student.

In a subjective opinion of the same two phones, the author would likely tell the audience as they start which phone is superior, and then spend the paper proving why by comparing the two. They would also present facts (cost, plans, apps, etc.), but they would add information from personal experience and their opinion of why some features are better than other.

A reader who wants to know more about the two phones before making her own decision would likely appreciate an objective comparison, while a reader who trusts the writer and wants to hear their opinion on the subject would likely appreciate a subjective comparison.

Getting started with comparison writing

The place to start with comparison writing is in choosing your subjects. Usually, this will involve two subjects (though longer papers might engage with more). Subjects are the main people, things, places, or ideas that we’ll be comparing or contrasting throughout the paper. Subjects must be related in some way. For example, I might choose to compare two college courses: even if their subjects are very different, because they are both classes, I will likely find ways to compare them.

Next, after researching the subjects, you’ll establish the points of comparison that you’ll use. These are the criteria that you’ll use to compare the two subjects, and they are your decision as a writer. For a short (3-5) page paper, you’ll usually select 3-4 points. Above, in the smartphone example, my points were: cost, app availability, plan pricing, weight, camera resolution, and reviews. I would likely narrow these down to focusing on three points.

How do I select points? This is generally where considering your audience comes into play: What would they be most interested in or convinced by? If I’m writing for a cost-conscious audience who also wants to be able to play games, I’d likely narrow down to cost, plan pricing, and apps available. I might choose something different (like durability or available security measures) if I was writing a paper to be read by parents of young children. The choice of comparison points is up to the writer, and your research should guide the decision you make. You’ll need to write about the same points for each subject.

Structuring comparison writing

The comparison essay can follow a set outline. In fact, two structures are common for comparison writing: the Point-by-Point structure and the Subject-by-Subject or Block structure. Both have advantages. They can also be combined, as needed.

Subject-by-Subject (Block) Structure

In subject-by-subject comparisons, each subject is tackled separately. After an introduction paragraph (covered later in this chapter), the paper goes directly into a section (one paragraph or multiple paragraphs) that addresses the first subject. This allows time to describe the subject for an unfamiliar audience or to place a concept in context. Then, after a transition, the second subject is discussed.

Within each section, the same points for comparison will be covered in approximately the same order and depth. Here’s an example outline for a subject-by-subject paper, written about two different types of smartphones:

1. Introduction
2. Subject A (Smartphone A)
   • General description of the phone
   • Cost
   • Available pricing plans
   • Available apps
3. Subject B (Smartphone AX)
   • General description of the phone
   • Cost
   • Available pricing plans
   • Available apps
4. Conclusion

Though it may appear that this essay is only four paragraphs long, it is useful to think of each number as a “section,” instead of a paragraph. The description might run for an entire paragraph when comparing two complex subjects: Consider, for example, an essay that wants to compare two video games. The first part of the subject discussion might be only about how the game is played and its major objectives, while the next paragraph would talk about its cost, time to play, and popular reviews.

Generally, in a subject-by-subject paper, during the second subject area (section 3), the writer will use comparison words to start reminding the reader of how things line up (or don’t) with the first subject.

Common Comparison/Contrast Words:

• Similarly
• Like
• Unlike
• In contrast
• On the other hand
• As shown before
• Just as
• Almost like

Point-by-point structure

In point-by-point comparison writing, the work is organized around the criteria for comparison. A sample outline would look like this:

1. Introduction
2. Point A (Phone cost)
   • Cost of Smartphone A
   • Cost of Smartphone AX
3. Point B (Pricing of phone plans)
   • Plans for Smartphone A
   • Plans for Smartphone AX
4. Point C (Available apps)
   • Apps on Smartphone A
   • Apps on Smartphone AX
5. Conclusion

The point-by-point structure means that both subjects are discussed side by side throughout the paper, which can be a great way to line up complicated topics or subjects which require frequent references to numbers. For example, in a paper comparing two potential vacation choices, the cost of many pieces of the trip might be important to see side by side: “If we travel to Island A, plane tickets will cost $476 per person, while Island B will cost $345 per person but will include a $50 baggage charge and a $20 shuttle ride.”

Point-by-point structure allows a writer to emphasize the importance of the categories for comparison over the subjects themselves. It can be a good format for informative papers or for papers where the comparison criteria are complex. For example, in our smartphone example, it may be difficult to explain why pricing plans for phones are so wildly different. A point-by-point structure would allow the writer to offer a quick explanation of types of plans before diving in to say how the two subjects stack up.

Though it may appear to be a longer structure than subject-by-subject, this is not necessarily true; again, think of the parts of the outline as sections instead of paragraphs, knowing that some parts may require more space to deal with than others.

Both outlines require the writer to frequently use comparison words and phrases. They also can be expanded to meet the needs of the assignment.

Comparison Introduction, Thesis, and Conclusion

Introduction

A comparison paper will begin with an introduction paragraph. This paragraph should, at minimum, establish for the reader that they are about to read a comparison/contrast essay. While that seems obvious, it’s easy to start a paper by talking only about one subject, or only about one point for comparison, which might lead a reader to think they’re going to read about only one idea. It can be useful to start the paper by describing why it’s important to study the differences or similarities between the two subjects: could it make a difference in the reader’s opinion or behavior?

If a comparison or contrast is being made between two subjects that will require the audience to have additional background knowledge, a secondary introduction may be necessary. For instance, if I were writing a paper comparing two characters from the Star Wars series, but my audience wasn’t guaranteed to have seen the films, I might put in a second paragraph that briefly described the plots of the relevant movies before getting into my character comparisons.

Thesis

Though by no means the only right place to put it, many comparison essays will have a thesis at the end of the first paragraph. The comparison thesis will name both subjects and will state whether they will be compared, contrasted, or both. An excellent thesis will also remind the reader of the importance of this comparison.

Example Thesis Statements

• Smartphone A and Smartphone AX look alike in the store, but a cost-conscious student should study their similarities and differences in price, plans, and apps to find which one will be the best fit.
• Though they were similarly popular as toys, R2-D2 and BB-8 served very different purposes in the Star Wars universe and continue to show the ways the movies have evolved.
• Harry Potter and Hermione Granger had radically different methods of studying, which could have led readers to favor one character over another.

Conclusion

The final section in a comparison paper is left for the conclusion. This can be a simple wrap-up, where the thesis is re-stated and the major points are reviewed. However, a comparison can also end with an additional discussion section, where the author considers and analyzes the two subjects and recommends or predicts which will be a better fit for the audience. In the smartphone example, a paragraph or two at the end might be reserved to discuss the features that weren’t described and why they aren’t as important, or to mention that both phones will soon be outdated. Discussion can be a useful way to bring in additional information or to place everything else in context.

Key Takeaways

Comparison/Contrast writing is frequently required in school and work settings. Keep in mind:

• Subjects are the main people, places, things, or ideas/concepts to be compared or contrasted (or both)
• Points are the criteria used to compare these subjects, and both subjects must be compared using the same points
• A subjective comparison draws a conclusion or evaluates the subjects at the end, based on the writer’s opinion.
• An objective comparison lets a reader become better informed about the subjects and allows them to draw their own conclusion
• Two structures (subject-by-subject or point-by-point) are usually used in basic comparison writing.
