How Much Do Reward Hackers Generalize?

TL;DR: Most discussion around CoT monitorability revolves around reducing pressure from RL. However, we should also be considering more adaptive behavior in which models avoid monitoring despite not being reinforced to do so. Whether models engage in non-reinforced reward hacking of this type depends on whether they have fully generalized to “get reward” rather than applying a limited set of reward hacking techniques that have been directly reinforced. I propose a potential experiment based on t...
