The four-step refutation
A simple pattern taught in many debate classrooms makes any answer clear:
- They say: restate the other side’s argument briefly and fairly. (“They say uniforms reduce bullying.”)
- But: state your answer in one sentence. (“But uniforms don’t remove the main causes of bullying.”)
- Because: give your reason and evidence. (“Because most bullying is about things uniforms don’t change, like social groups, looks and online behavior; and studies of uniform policies find mixed effects on behavior.”)
- Therefore: say what that means for the round. (“Therefore their first contention doesn’t give you a reason to require uniforms.”)
They say They say uniforms take away students’ freedom to express themselves.
But But students keep many ways to express themselves at school.
Because Because uniforms cover clothing only. Students still choose their words, art, activities, clubs and friends, and many uniform policies allow choices of color, outerwear or accessories.
Therefore Therefore the loss of expression is small, and our benefit of a more focused classroom outweighs it.
The same method works for both sides. Restating fairly in step one is not a courtesy only: if you restate the argument wrongly, the judge notices, and your answer misses.
Ways to answer an argument
| Answer | What it says | Example |
|---|---|---|
| Deny the claim | It isn’t true. | “Year-round school doesn’t add learning days; most calendars have the same 180 days, just spread out.” |
| Attack the warrant | The reason doesn’t support the claim. | “Their study shows uniform schools have fewer fights, but those schools also added security staff the same year.” |
| Challenge the evidence | The source is weak, old, or doesn’t say that. | “Their card is from 2009, before most students had smartphones.” |
| Mitigate the impact | It’s true, but smaller than they say. | “The savings are real but small, a few dollars a family each year.” |
| Turn it | It actually helps our side. | “Their own evidence says the policy raised costs for the poorest families, which is our point.” |
| Outweigh | Even if they’re right, our impact matters more. | “Even if it costs more, the safety benefit is bigger and longer-lasting.” |
Dropped arguments
If the other side doesn’t answer one of your arguments, it is dropped (or conceded). Point it out: “They never answered our second contention, so you can treat it as true.” Then explain why it matters. A dropped argument helps only if you extend it: say it again in your next speech and explain its impact.
The flip side: answer everything that matters. Use your flow (see Flowing) to check that every argument against you has an answer.
What rebuttals are for
In most formats, rebuttals may not bring brand-new arguments. You can bring new answers to arguments already made and new evidence for them, but not a new contention. When in doubt, tie everything back to something already in the round.
- Answer what the other side said in their last speech.
- Rebuild your own arguments that they attacked.
- Extend your best arguments (claim, warrant and impact, briefly).
- Weigh: compare your impacts with theirs (see Weighing).
- Crystallize: tell the judge the one or two issues the round comes down to, and why you win them.
Grouping and ordering
When the other side makes several similar arguments, group them: “Their three points about cost all depend on one study, so I’ll answer them together.” Give a roadmap at the start of a rebuttal (“I’ll go to their case, then ours”) and follow it.
Practice
- Choose any argument from a topic page and refute it in four steps out loud in under 30 seconds.
- Write one answer of each kind (deny, warrant, evidence, mitigate, turn, outweigh) to the same argument.
- Give a two-minute rebuttal to a partner’s one-minute speech, starting with a roadmap.
