Rationalists can probably to an extent choose not to suffer from envy (just because they’re more likely to understand that the effect exists and is a bad thing), whereas they can’t choose not to suffer from infrastructural detriments.

(This is one of many examples where it’s tempting to overestimate science because it’s tempting to underestimate the number of different ways in which the question the science asks differs from the question you want to know the answer to.)
