9.1 Joining an ongoing conversation
Most issues were being argued long before you arrived, so a strong argument responds to positions people have already taken. As you gather sources, sort them by whether they support your thesis, complement it by adding something new, or contradict it. That map of the conversation tells you where your own argument fits.

Arguments are part of a conversation
Think of an issue as a long conversation at a crowded table. People have already made claims, offered evidence and answered each other. If you walk up and repeat what someone said an hour ago, or ignore what everyone's been saying, no one will take you seriously. To join well, you listen first, then respond to what's actually been said.
In writing, that means showing readers which positions already exist and how yours relates to them. Do you agree with one side and add a new reason? Do you think both sides are missing something? Do you accept a common view but limit where it applies? Your thesis is more interesting when readers can see what it's responding to.
Support, complement, contradict
Every piece of evidence or source relates to your thesis in one of three ways:
| Relationship | What it means | How you use it |
|---|---|---|
| Supports | Backs up your claim directly | As evidence in a body paragraph |
| Complements | Adds a different angle, reason or example that fits with your claim without repeating it | To broaden your line of reasoning or add a new kind of evidence |
| Contradicts | Pushes against your claim | To concede, rebut or refute (9.2, 9.3), or as a reason to revise your thesis (6.5) |
Mapping the conversation
Before you write, especially on the synthesis essay, make a quick map. For each source, jot its position and a word or two about its perspective (6.3). Then group the sources: which ones agree, which add new dimensions, which disagree? You'll often find that the disagreement isn't really "for" versus "against," but about a specific point: cost, fairness, who benefits.
That specific point of disagreement is where your argument can do the most work. A thesis that takes a position on the real point of tension, instead of the broad yes-or-no question, shows you understand the conversation. Exploring those tensions across the sources is one of the ways to earn the sophistication point.
Joining the conversation on the argument essay
The argument essay doesn't give you sources, but the conversation still exists. You can bring it in through what you know: how people have commonly argued about the issue, a historical debate, a well-known example. Briefly showing the usual positions, then explaining where yours fits, makes even a short timed essay feel like it's responding to something real.
Worked examples
Try each one yourself first, then open the solution.
- Example 1
Sorting sources and entering the conversation
Practice sources (written for this practice set; all invented), on whether a city should close part of its downtown to cars on weekends. Your working thesis: The city should close Main Street to cars on weekends. Source A: A survey of downtown shop owners after a trial car-free weekend found most reported higher sales. Source B: A public health researcher notes that people walk more when streets are pleasant and safe. Source C: A disability rights group warns that closures make it hard for people who can't walk far to reach downtown businesses. Source D: A city traffic study finds that weekend traffic on Main Street is light compared with weekdays. Label each source as supporting, complementing or contradicting the thesis. Then write two sentences that enter the conversation.
Show the solutionHide the solution
- Step 1: A directly supports the thesis: businesses benefit, which answers a common worry.
- Step 2: B complements it: it adds a different reason, health, that the business argument doesn't cover.
- Step 3: D supports it in a narrower way: weekends are the time a closure would disrupt the least traffic.
- Step 4: C contradicts it, at least in its current form. It raises a fairness issue the thesis ignores.
- Step 5: Find the real point of tension: not "cars versus no cars" but access for everyone. Use C to sharpen the thesis rather than ignore it.
- Step 6: Write an opening that names the usual debate and shows where your position fits.
Answer: A supports, B complements, C contradicts, D supports. Model sentences: "Debates over car-free streets usually pit shop owners against drivers, but the trial weekend suggests that businesses gain more than they lose (Source A), and the more pressing question is who can still get downtown. The city should close Main Street to cars on weekends, as long as it keeps drop-off zones and shuttle access at each end, so that people who cannot walk long distances can still reach the businesses they rely on (Source C)."
Common mistakes
- Writing as if your position is the first anyone has thought of. Show what others have said, then respond.
- Treating every source as simply "for" or "against." Many sources complement your thesis by adding a new angle.
- Leaving contradicting sources out of your essay. On the synthesis essay, a contradicting source is often your best chance to show complex thinking.
On the exam
- On the synthesis essay, a thesis that responds to the specific point of tension among the sources usually leads to a more nuanced line of reasoning.
- Reading questions may ask how a source or paragraph relates to the writer's claim: does it support, extend or challenge it? Check the logical relationship, not just the topic.
