Note: it’s unclear to me how the category of “evolutionary restrictions” could apply to rationality techniques.
Opportunity costs of applying system 2? It seems like an important rationality technique is “just stop and think about it for, like, thirty seconds, instead of jumping to the first conclusion your brain throws up”. I suggest that this may have been costlier, relative to available nutrients, in the ancestral environment; it’s also possible that we now more rarely face the kind of problem where any answer, even wrong, is better than standing about. (Although I guess that comes under changed tradeoffs, actually.)
