WSDC reply speech structure

The reply isn't a 4th constructive. It's a closing argument. Two issues, no new matter, weighing-first, biased toward your side.

In short

What the reply speech is for

WSDC reply speeches sit at the end of the round, after the 3rd-speaker rebuttals. They are 4 minutes long and delivered by the 1st or 2nd speaker on each side (never the 3rd). The Opposition replies first; Proposition replies last and gets the final word.

The reply is not a 4th constructive. It is a closing argument. Treat it the way a lawyer treats closing: organize the round into 2-3 issues, walk the judge through why your side wins each, and end with one image they'll carry into the ballot.

The two-issue structure

The strongest reply speeches identify 2 (sometimes 3) issues that the round actually turned on, and walk each one. An issue is bigger than an argument; it's a thematic axis the round was clashing on.

Example, motion = "THBT social media platforms should be liable for user content." Issues might be: (1) Speech and chilling effects, (2) Platform incentives and content quality. Notice these aren't individual contentions; they're frames that cover multiple contentions from both sides.

Walking each issue: name the issue, summarize your side's strongest line, summarize Opp's strongest line, then weigh. Don't rebut every individual point. Pick the central clash and resolve it.

The "no new matter" rule and how to bend it

WSDC adjudicators strike new arguments in reply. But they accept new comparisons, new weighing, new examples that illustrate existing arguments, and new responses to attacks Opp made in the 3rd rebuttal.

The trick: frame everything as something already in the round. "Building on the inequality argument from our 2nd speaker, here's the new framing: the only people who benefit from the status quo are the ones already insulated from its costs." The argument is new-ish; the framing presents it as extending what's on the flow.

Adjudicators will let you get away with this if it's clearly downstream of existing matter. They will not let you introduce a whole new contention. Know the line.

Bias the framing: that's your job in reply

The constructives have to be balanced; the reply does not. You're the closer. Your job is to characterize the round in a way that makes your side look like the obvious winner.

Example: "This round turned on one question: who bears the cost of the status quo? Proposition said children. Opposition said platform innovation. You as an adjudicator have to decide whose harm matters more. Here's why ours does, and here's why theirs is speculative."

Notice the framing already cast their side as "speculative" and yours as concrete. That's the move. You don't have to hide it. Adjudicators expect partisan framing in the reply.

The closing image

End on one image, not a recap. Recaps are dead weight by minute 3:40. An image is something the adjudicator can write on the flow and remember when they're filling out the ballot.

Example: "If you adopt our side, the next time a 14-year-old gets targeted by an algorithmic feed designed to maximize their engagement at the cost of their wellbeing, there's a remedy. If you adopt their side, there isn't. That's the round."

Don't end with 'and therefore we propose.' End with the image.

Sample lines

Opening the reply (Opposition replying first).
"This round turned on two issues. One: whether liability actually changes platform behavior in the direction Prop claimed. Two: who bears the cost of getting that wrong."
Two-issue structure stated up front. The adjudicator knows what they're tracking for the next 4 minutes.
Closing image, Proposition reply.
"If you adopt our side and we're wrong, platforms moderate slightly more cautiously. If you adopt their side and they're wrong, the harm we documented continues. That's the asymmetry."
Frames the round as a risk asymmetry the adjudicator can resolve in one line. No new argument; new weighing.
