Cross-examination and POIs: the shared-time game

The setup-not-win principle

Cross-examination, PF crossfire, and BP points of information are shared airtime. Both sides can ask and answer. The judge is watching for who controls the exchange, not who scores literal points.

Novices think cross-ex is for winning. They try to corner the opponent into admitting they are wrong, and when the opponent does not crack, they walk away frustrated. Varsity treats cross-ex as setup. The goal is not to win the exchange in real time; it is to extract a quote or a concession that comes back in the next speech.

A typical varsity cross-ex extracts two or three quotable answers. In the next speech: "On cross, my opponent confirmed that the warrant rests on a 2015 study. I have the 2023 update; the number has been revised downward by 60 percent." That is the cross-ex win, delivered 90 seconds after the exchange ended.

Concession-first questions

Phrasing matters. "Would you agree that X?" is harder for them to refuse than "What do you think about X?" The first frames a concession; the second hands them a microphone.

Good concession-first questions:

"Would you agree that the warming trend in your evidence is global, not localized?"

"You said earlier that markets self-correct. Is there a timeframe on that?"

"Does your contention 1 evidence cover the post-2020 period or end in 2018?"

Each locks them into a position you can exploit. If they agree, you have the concession. If they refuse, you ask them to explain why and they are now defending a position they should not be defending.

The "never ask why" rule

"Why do you think X" is a free 45-second speech for your opponent. They will use it to re-explain their case, add warrants you could not flow in the constructive, and run out the clock.

Replace "why" with structural questions: "Can you point to the specific evidence?" "Which contention does that fall under?" "What is the timeframe?" "Is your impact reversible?" These force short factual answers, not extended argumentation.

If you actually need to attack a warrant, attack it in your next speech, not in cross-ex. Cross-ex is for setup, not for fighting. Reserve the speech for the kill.

Controlling the exchange

Cross-ex is not polite conversation; it is shared airtime. If they are running long on an answer, cut them: "I have my answer, moving on." Adjudicators expect this. Letting your opponent monologue for 90 seconds while you stand there is a sign you have lost control.

Conversely, when they ask you a question, decide whether to answer fully (when it is a softball), partially (when they are fishing), or pivot ("That is a fair question; the more important issue is X").

Do not talk over each other. Two debaters arguing simultaneously is unflowable. If they are talking, wait one beat, then jump in clean: "Let me finish that thought." Polite, firm, controlled.

Format-specific cross-ex

In Policy, cross-examination is one-on-one for 3 minutes after each constructive. The questioning side controls the floor; the answering side has to respond. Adjudicators flow cross-ex.

In PF, crossfire is shared 3-minute time where both sides can ask and answer. Pace matters: rapid concession-first questions beat slow exploratory ones.

In Parliamentary formats (APDA, BP, Asian Parli, WSDC), POIs are 15-second interruptions during constructive speeches. Take 1-2; refuse the rest cleanly. The asking side is also scored, so a strong POI raises both speakers' marks.
