Prerequisites of Debate

CF treats debate as a mechanism for error correction, and like any mechanism it has conditions that must hold before it can work. Naming these prerequisites explains why most real-world debates are unproductive: the conditions are simply missing.

CF identifies three. First, at least one participant must understand what a productive debate actually looks like and be able to moderate it. Without that competence, debate tends to become disorganized; CF’s advice is to switch to collaboration instead, or—if disagreement is strong and attitudes adversarial—to abort or find a moderator. Second, the participants must genuinely care about the topic and prefer, all else equal, to try to reach a conclusion rather than stopping early. Third, each person must already know how to win the debate unopposed: if your opponent stayed silent the whole time and you still couldn’t establish your claim, you weren’t ready to assert it. This means knowing conclusive arguments and evidence, and being able to state the objectively correct goalposts and show your reasoning clears them—not merely listing pros for your side and cons against the other.

The third prerequisite leans on CF’s notion of a good-enough bar: a debater should know what threshold is sufficient for reasonable, unbiased people to conclude. (If you reason in probabilities instead, make a definite claim like “at least 80% likely” and justify it.) Crucially, “conclusive” here is fallibilist and tentative: the best knowledge available now, enough to decide and move on, yet still open to revision given new arguments or evidence. CF’s debate policies exist largely to secure these prerequisites so that debates can correct error rather than entrench it.
