One way to think about what’s happening here, using a more predictive-models-style lens: the first-order effect of updating the model’s prior on “looks helpful” is going to give you a more helpful posterior, but it’s also going to upweight whatever weird harmful things actually look harmless a bunch of the time, e.g. a Waluigi.
Put another way: once you’ve asked for helpfulness, the only hypotheses left are those that are consistent with previously being helpful, which means when you do get harmfulness, it’ll be weird. And while the sort of weirdness you get from a Waluigi doesn’t seem itself existentially dangerous, there are other weird hypotheses that are consistent with previously being helpful that could be existentially dangerous, such as the hypothesis that it should be predicting a deceptively aligned AI.
