To write a compare/contrast essay, you’ll need to make NEW connections and/or express NEW differences between two things. The key word here…is NEW!
- Choose 2 things that could go in the same category, but are also quite different. Good choices might be:
- Basketball & Football (both sports)
- Horses & Cats (both animals, but different in many ways)
- Writing & Singing (both art forms, but different in many ways)
- Gather your ideas by writing down characteristics of each thing. Note the differences and similarities between them.
- Ask yourself these important questions before you begin writing your draft:
Does my instructor want me to compare AND contrast, or am I only being asked to do one of those things?
Some instructors prefer that you only write about the differences between two things, while others want you to focus on explaining the similarities as well. Either way, you'll need to make sure that your thesis statement reflects your instructor's expectations. For example, if I wanted to write about Social Networking sites, I'd need to write different thesis statements depending on my compare/contrast assignment.
Sample thesis statement for contrast paper: In terms of social networking sites, Facebook focuses on presenting your daily life to others, whereas MySpace allows you to focus more on demonstrating your personal style.
Sample thesis statement for compare/contrast paper: While both Facebook and MySpace allow you to meet other users who have similar interests, only MySpace allows you to demonstrate your personal style.
Are these 2 things similar and/or different, in at least one meaningful way?
If you want to write a successful compare/contrast essay, you'll need to avoid writing about really obvious differences and similarities. For example:
- We all know that horses are larger than cats.
- We also know that basketball teams contain less players than football teams.
Tell us something we don't know (or might not notice)!
It would be better to write about how sensitive both horses and cats are to human needs and emotions. You could also suggest that though both basketball and football require a lot of teamwork, basketball players are expected to be a lot more versatile than football players.
You don't have to be a genius to write an interesting compare/contrast essay--you just have to look at ordinary things in a new way!
Do I know enough about my topic to write an effective compare/contrast essay?
Unless you're being asked to do some research as part of your compare/contrast project, make sure that you choose 2 things that you feel comfortable discussing, at length.
Your instructor may ask for multiple similarities and differences--make sure you're prepared to write a well-developed, meaningful essay on a topic that you know well before you get started!
Organizing Your Compare and Contrast Paper
There are two primary ways to organize your compare and contrast paper.
Chunking: placing all of the information for each individual subject in one place (chunk), and then using similarities as transitions.
Here’s a sample outline:
- Jane is distinct because…
- Jane is similar to Alice in these ways
- Alice is distinct because…
Piecing: giving pieces of the information for each individual subject in each paragraph—arranging the information by topic rather than by subject.
Here’s a sample outline:
- Differences and Similarities in Jane and Alice’s appearances
- Differences and Similarities in Jane and Alice’s backgrounds
- Differences and Similarities in Jane and Alice’s interests
Throughout your academic career, you'll be asked to write papers in which you compare and contrast two things: two texts, two theories, two historical figures, two scientific processes, and so on. "Classic" compare-and-contrast papers, in which you weight A and B equally, may be about two similar things that have crucial differences (two pesticides with different effects on the environment) or two similar things that have crucial differences, yet turn out to have surprising commonalities (two politicians with vastly different world views who voice unexpectedly similar perspectives on sexual harassment).
In the "lens" (or "keyhole") comparison, in which you weight A less heavily than B, you use A as a lens through which to view B. Just as looking through a pair of glasses changes the way you see an object, using A as a framework for understanding B changes the way you see B. Lens comparisons are useful for illuminating, critiquing, or challenging the stability of a thing that, before the analysis, seemed perfectly understood. Often, lens comparisons take time into account: earlier texts, events, or historical figures may illuminate later ones, and vice versa.
Faced with a daunting list of seemingly unrelated similarities and differences, you may feel confused about how to construct a paper that isn't just a mechanical exercise in which you first state all the features that A and B have in common, and then state all the ways in which A and B are different. Predictably, the thesis of such a paper is usually an assertion that A and B are very similar yet not so similar after all. To write a good compare-and-contrast paper, you must take your raw data—the similarities and differences you've observed—and make them cohere into a meaningful argument. Here are the five elements required.
Frame of Reference. This is the context within which you place the two things you plan to compare and contrast; it is the umbrella under which you have grouped them. The frame of reference may consist of an idea, theme, question, problem, or theory; a group of similar things from which you extract two for special attention; biographical or historical information. The best frames of reference are constructed from specific sources rather than your own thoughts or observations. Thus, in a paper comparing how two writers redefine social norms of masculinity, you would be better off quoting a sociologist on the topic of masculinity than spinning out potentially banal-sounding theories of your own. Most assignments tell you exactly what the frame of reference should be, and most courses supply sources for constructing it. If you encounter an assignment that fails to provide a frame of reference, you must come up with one on your own. A paper without such a context would have no angle on the material, no focus or frame for the writer to propose a meaningful argument.
Grounds for Comparison. Let's say you're writing a paper on global food distribution, and you've chosen to compare apples and oranges. Why these particular fruits? Why not pears and bananas? The rationale behind your choice, the grounds for comparison, lets your reader know why your choice is deliberate and meaningful, not random. For instance, in a paper asking how the "discourse of domesticity" has been used in the abortion debate, the grounds for comparison are obvious; the issue has two conflicting sides, pro-choice and pro-life. In a paper comparing the effects of acid rain on two forest sites, your choice of sites is less obvious. A paper focusing on similarly aged forest stands in Maine and the Catskills will be set up differently from one comparing a new forest stand in the White Mountains with an old forest in the same region. You need to indicate the reasoning behind your choice.
Thesis. The grounds for comparison anticipates the comparative nature of your thesis. As in any argumentative paper, your thesis statement will convey the gist of your argument, which necessarily follows from your frame of reference. But in a compare-and-contrast, the thesis depends on how the two things you've chosen to compare actually relate to one another. Do they extend, corroborate, complicate, contradict, correct, or debate one another? In the most common compare-and-contrast paper—one focusing on differences—you can indicate the precise relationship between A and B by using the word "whereas" in your thesis:
Whereas Camus perceives ideology as secondary to the need to address a specific historical moment of colonialism, Fanon perceives a revolutionary ideology as the impetus to reshape Algeria's history in a direction toward independence.
Whether your paper focuses primarily on difference or similarity, you need to make the relationship between A and B clear in your thesis. This relationship is at the heart of any compare-and-contrast paper.
Organizational Scheme. Your introduction will include your frame of reference, grounds for comparison, and thesis. There are two basic ways to organize the body of your paper.
- In text-by-text, you discuss all of A, then all of B.
- In point-by-point, you alternate points about A with comparable points about B.
If you think that B extends A, you'll probably use a text-by-text scheme; if you see A and B engaged in debate, a point-by-point scheme will draw attention to the conflict. Be aware, however, that the point-by- point scheme can come off as a ping-pong game. You can avoid this effect by grouping more than one point together, thereby cutting down on the number of times you alternate from A to B. But no matter which organizational scheme you choose, you need not give equal time to similarities and differences. In fact, your paper will be more interesting if you get to the heart of your argument as quickly as possible. Thus, a paper on two evolutionary theorists' different interpretations of specific archaeological findings might have as few as two or three sentences in the introduction on similarities and at most a paragraph or two to set up the contrast between the theorists' positions. The rest of the paper, whether organized text- by-text or point-by-point, will treat the two theorists' differences.
You can organize a classic compare-and-contrast paper either text-by-text or point-by-point. But in a "lens" comparison, in which you spend significantly less time on A (the lens) than on B (the focal text), you almost always organize text-by-text. That's because A and B are not strictly comparable: A is merely a tool for helping you discover whether or not B's nature is actually what expectations have led you to believe it is.
Linking of A and B. All argumentative papers require you to link each point in the argument back to the thesis. Without such links, your reader will be unable to see how new sections logically and systematically advance your argument. In a compare-and contrast, you also need to make links between A and B in the body of your essay if you want your paper to hold together. To make these links, use transitional expressions of comparison and contrast (similarly, moreover, likewise, on the contrary, conversely, on the other hand) and contrastive vocabulary (in the example below, Southerner/Northerner).
As a girl raised in the faded glory of the Old South, amid mystical tales of magnolias and moonlight, the mother remains part of a dying generation. Surrounded by hard times, racial conflict, and limited opportunities, Julian, on the other hand, feels repelled by the provincial nature of home, and represents a new Southerner, one who sees his native land through a condescending Northerner's eyes.
