Not quite what we were trying to say in the post. Rather than tradeoffs being decided on reflection, we were trying to talk about the causal-inference-style “explaining away” which the reflection gives enough compute for. In Johannes’s example, the idea is that the sadist might model the reward as coming potentially from two independent causes: a hardcoded sadist response, and “actually” valuing the pain caused. Since the probability of one cause, given the effect, goes down when we also know that the other cause definitely obtained, the sadist might lower their probability that they actually value hurting people given that (after reflection) they’re quite sure they are hardcoded to get reward for it. That’s how it’s analagous to the ant thing.
