Writing for Different Formats: LD, PF, and Policy

The Format Shapes the Case

A common mistake among novice debaters is writing one case and trying to shoehorn it into any format. In reality, Lincoln-Douglas, Public Forum, and Policy debate have fundamentally different expectations for what a case should contain, how evidence is used, and what judges evaluate. A winning LD case would fail in Policy, and a strong Policy case would confuse a PF judge.

The differences stem from each format's intellectual DNA. Lincoln-Douglas grew out of philosophy and ethics, emphasizing values and criteria. Public Forum was designed for accessibility, rewarding persuasion and real-world evidence over technical jargon. Policy debate prizes depth, quantity of evidence, and systemic analysis of a single resolution over an entire season. Understanding these roots helps you write cases that judges in each format actually want to hear.

Lincoln-Douglas: Values and Criteria

An LD case is built around a philosophical framework. Your case must identify a value (justice, liberty, equality, morality) and a criterion that explains how we measure whether the value is achieved. The criterion is the lens through which the judge should evaluate all arguments in the round.

A standard LD affirmative case includes: (1) definitions of key terms in the resolution, (2) a value and value criterion with philosophical justification, (3) two to three contentions that link to the criterion, and (4) evidence from philosophical texts, legal scholars, and empirical data. LD contentions should read more like persuasive philosophical arguments than policy briefs. You are arguing about what ought to be, not proposing a specific plan of action.

The most effective LD cases create a tight chain from value to criterion to contentions, where each contention proves the criterion is met, and the criterion proves the value is upheld. If a judge can follow this chain without any logical leaps, your case is structurally sound.

Public Forum: Accessible and Evidence-Driven

PF cases are shorter and punchier than LD or Policy. A constructive speech is only four minutes, so your case typically has two to three contentions supported by recent, credible evidence from mainstream sources like the Brookings Institution, Council on Foreign Relations, or peer-reviewed journals. PF judges reward clarity and real-world impact over philosophical depth. Your taglines should be immediately understandable, and your evidence should tell a story a lay audience can follow.

Policy: The Comprehensive Blueprint

Policy cases are the most complex. An affirmative case must present a specific plan that solves a problem within the resolution's scope. The standard structure is: (1) inherency (the problem exists under the status quo), (2) a plan text with specific mandates, funding, and enforcement, (3) solvency (the plan actually fixes the problem), and (4) advantages (the positive impacts of the plan). Policy debaters read far more evidence per speech than any other format, often cutting hundreds of cards from academic journals, government reports, and think tank publications across a single season.
