A Simpler and Better Debate Protocol for Scalable Oversight

Linkpost to arXiv: https://arxiv.org/abs/2610.02557 Summary: One promising approach to scalable oversight is AI debate, which seeks to leverage a debate between two powerful AIs to break complex questions down into simpler claims that can be easily judged directly. Theoretical work on debate aims to design protocols (i.e., rules of the debate game) that provide rigorous guarantees on correctness, and the current best protocol works for all problems that have sufficiently stable decompositions into subproblems. We design a new protocol, FBS Debate, for this same class of problems that improves
