Yeah, it’s possible that CoT training unlocks reward hacking in a way that wasn’t previously possible. This could be mitigated at least somewhat by continuing to train the reward function online, and letting the reward function use CoT too (like OpenAI’s “deliberative alignment” but more general).
I think a better analogy than martial arts would be writing. I don’t have a lot of experience with writing fiction, so I wouldn’t be very good at it, but I do have a decent ability to tell good fiction from bad fiction. If I practiced writing fiction for a year, I think I’d be a lot better at it by the end, even if I never showed it to anyone else to critique. Generally, evaluation is easier than generation.
Martial arts is different because it involves putting your body in OOD situations that you are probably pretty poor at evaluating, whereas “looking at a page of fiction” is a situation that I (and LLMs) are much more familiar with.
