Debate Fundamentals
Formats, flow, judging paradigms — the skills that transfer across every style of competitive debate.
Formats
Lincoln-Douglas (LD)
A one-on-one values debate. Rounds revolve around a resolution framed around competing values (e.g., 'Justice ought to be valued above utility'). The affirmative defends the resolution; the negative contests it. Founded by the National Speech & Debate Association (NSDA) in the 1980s, LD is the dominant one-on-one US high school format.
Key Points
- Value premise + value criterion: every LD case is grounded in a philosophical value and a standard for achieving it.
- Speech times: 6-3-7-3-4-6-3 (AC, CX, NC, CX, 1AR, NR, 2AR).
- Judges often weigh on framework, philosophy (Kant, Rawls, Mill), and evidence.
Public Forum (PF)
A two-on-two policy debate on current events, designed to be accessible to lay judges. The NSDA introduced PF in 2002 explicitly to counter the insider jargon that dominated Policy debate. Evidence-heavy but presented in plain English.
Key Points
- Speech times: 4-4-3-4-4-3-2-3-2-3 (typical NSDA structure).
- Coin flip determines side and speaking order — both pro and con prep matters.
- Crossfire (shared cross-examination) is the signature element.
British Parliamentary (BP)
Four teams of two. Two on Proposition, two on Opposition, split into Opening and Closing benches. Used at the World Universities Debating Championship (WUDC) and across European circuits.
Key Points
- 15-minute prep after motion release; no internet, no pre-written speeches.
- Teams compete against their own side as much as the opponents — ranked 1st through 4th.
- Speech times: 7 minutes each; 15 seconds protected at start and end.
Policy (CX)
Two-on-two debate on a season-long policy resolution (e.g., 'The US federal government should substantially increase...'). Most evidence-intensive format: teams carry tubs of cards. NSDA and NDCA (college) circuits.
Key Points
- Stock issues: harms, inherency, solvency, topicality, disadvantages.
- Speech times: 8-3-8-3-8-3-8-3 constructives/CX + 5-5-5-5 rebuttals.
- Spreading (fast delivery) is common — but prize clarity with lay judges.
World Schools Debating (WSDC)
A three-person team format run at WSDC since 1988. Blend of British Parliamentary and American Policy styles. Half the motions are prepared, half impromptu.
Key Points
- Speech times: 8 minutes each with Points of Information allowed after the first minute.
- Style (delivery + engagement) is scored alongside content and strategy.
- Reply speech is 4 minutes — a biased summary of why your side won.
Flow & Judging
How to flow a round
'Flowing' is taking structured notes across speeches so every argument is tracked from introduction to extension to weigh. A good flow tells you at any moment what's been dropped, what's contested, and what's winning.
Key Points
- Use columns per speech; abbreviate aggressively (e.g., 'F/L' = frontline, 'X' = turned, '➝' = caused).
- Track responses horizontally so a dropped argument is visually obvious.
- Separate flows for each contention or off-case position.
Judging paradigms
Tab (tabula rasa)
The judge evaluates what's said in the round, intervening as little as possible. Tech over truth — if evidence is dropped, it's conceded.
Policymaker
The judge imagines themselves as a policymaker choosing between the two advocacies. Weigh plan vs counterplan on probability, magnitude, and timeframe.
Stock issues
Classic Policy paradigm — the affirmative must win every stock issue (harms, inherency, solvency, topicality) or lose.
Communication
Lay or parent judges — clarity, persuasion, and presence matter as much as technical accuracy.
FAQ
Can I switch formats mid-season?
Yes, but prioritize mastering one format first. Skills transfer — evidence reading, crossfire, impact weighing — but speech times and argument conventions don't. Give yourself 3-4 practice rounds before a tournament in a new format.
Should I learn to spread?
Only in Policy and some LD circuits. Lay judges penalize unclear delivery. If you do spread, drill articulation daily — the Harvard Debate Council recommends tongue twisters and pen-in-mouth reading exercises.
Where do competitive debaters get evidence?
Primary sources first: CRS Reports, government statistics, peer-reviewed journals. Secondary sources next: The Economist, Foreign Affairs, Brookings, CFR. Avoid blogs and opinion sites unless the author is the argument (e.g., Judith Butler on identity).
