The passage around this formula
Debate targets the oversight ceiling directly rather than working around it, and its motivation is stated in explicitly theoretical terms. Irving, Christiano, and Amodei propose training two agents through self-play in a zero-sum game: each argues a position in alternating statements, and a human judge decides which one gave more true, useful information. The paper’s central theoretical claim draws an analogy to computational complexity theory, arguing that if optimal play in the debate game tracks truth, then a judge with only polynomial-time reasoning ability could in principle adjudicate a debate about problems in the complexity class PSPACE — that is, questions considerably harder than…
