The purpose of a reply speech
Think of the reply as a biased adjudication. A real adjudicator sits down after the round and asks: what were the main points of disagreement, who won each, and which mattered most? Your reply answers those questions in a way that favors your side but stays honest about what was actually said.
That is why a reply that simply restates your case fails even when the case was good. The adjudicator already heard it. What they have not heard is your account of how the two cases interacted.
Identifying the decisive clashes
A clash is not a topic; it is a disagreement with two competing answers. "The economy" is a topic. "Whether the policy raises wages for low-income workers or prices them out of the market" is a clash. Naming clashes precisely is most of the work.
Choose the clashes that could change the result. If a disagreement was won by your opponents but does not affect who wins the round, say so briefly and move on rather than pretending it did not happen.
Comparing both teams
For each clash, do three things: state the strongest version of what the other side argued, state what your side argued, and explain why yours survives the exchange. Taking their best case seriously is persuasive; caricaturing it is not, and adjudicators notice.
The word that separates a strong reply from a weak one is usually "because." Not "we won this clash," but "we win this clash because their mechanism required an assumption they never defended, and ours was tested twice and held."
Weighing impacts
Weighing is comparison with a conclusion. Identifying two impacts is not weighing. Explaining both is not weighing either. Weighing is saying which one matters more, why it matters more, and how that comparison decides the clash.
Useful comparisons
Who is affected and how vulnerable are they; how severe and how reversible the harm is; how likely the outcome is; how soon it arrives; and how many people it reaches.
Finish the comparison
End each weighing move with a conclusion: "so even if their benefit happens, it is smaller, slower and easier to reverse than the harm we described."
Strategic collapse into one decisive clash
A World Schools reply may legitimately collapse the debate into a single clash when that clash genuinely subsumes the others. If everything the other side wins depends on their mechanism working, and you have shown it does not, then the mechanism is the round, and spending your four minutes on it is the right call.
Collapse is a strategic choice, not a shortcut. To do it well, name the clash, explain explicitly why the other issues depend on it or cannot outweigh it, and then resolve it thoroughly. What makes collapse fail is leaving live issues unaddressed with no explanation of why they do not matter.
A reply does not mechanically need several clashes. One decisively crystallized clash that subsumes the debate can be stronger than three summarized shallowly. What a reply always needs is comparison and a conclusion, whether it covers one issue or three.
No new substantive arguments
You may reframe, prioritize, compare, and draw out implications of analysis already given. You may not add a new argument, a new mechanism, or a new independent reason to vote for you. A useful test: could this sentence have been said only because it is the reply? If it brings in something the other side never had a chance to answer, cut it.
A four-minute structure
0:00 – 0:30 — Frame the round
State in one or two sentences what this debate came down to and what the adjudicator should be deciding.
0:30 – 2:00 — The decisive clash
Take the issue that determines the round. Say what both teams argued, why your side's analysis survives, and why the outcome follows.
2:00 – 3:15 — The remaining issues
Handle the other live issues briefly, or explain why they are subsumed by the first clash and cannot change the result.
3:15 – 4:00 — Weigh and close
Compare the importance of the issues, then give one clear sentence the judge could write on the ballot.
Timings are a guide, not a rule. If your tournament uses shorter replies, keep the same shape and compress the middle sections.
Common mistakes
- Chronological summary: walking through all six speeches in order instead of organizing by issue.
- Restatement disguised as summary: repeating your arguments louder without comparing them to anything.
- Listing without resolving: naming four clashes and never saying who won them or which mattered most.
- Answering their weakest point: adjudicators score comparison against the strongest version of the other case.
- New material: the fastest way to lose Strategy credit in a reply.
A short worked example
Suppose the motion is that a city should make public transport free at the point of use. The Proposition argued it cuts car use and helps low-income commuters; the Opposition argued the lost fare revenue degrades service quality until the network serves people worse.
"This round comes down to one question: does removing fares make the network better or worse for the people who depend on it? Everything else follows from that. They told you ridership rises — we agreed, and that is exactly the problem, because their own case gave no funding source for the extra capacity that rising ridership requires. Our reliability analysis was never answered: crowded buses with no new vehicles means longer waits for the commuters they named as the beneficiaries. Even taking their environmental benefit at its highest, it depends on people choosing the bus over the car — and people choose the bus when it is reliable, not when it is free. So their benefit runs through our harm, and that is why you oppose."
Notice what the example does: it collapses deliberately, engages the strongest version of the other case, and finishes the comparison with a conclusion rather than an assertion.
Practice the reply, not just the case
Reply speeches improve fastest when you deliver them under time and get feedback on whether you actually completed the comparison. You can practice replies for either side in DebatePilot, or read how adjudicators score speeches before your next round.
