I never said all tropes are bad. And even saying SOME are bad was only in the context of training rationality. Most tropes are, however, divergences from reality that the human brain are prone to make, and thus looking for them might be useful in making a game more similar to reality. This is different from realism by the way, realism is about fact inside the work of fiction having the same answers as IRL, the reality-similarity we want for a rationalist game however are on the decision theoretical level, and in fact the first kind of realism might be directly bad as it allows players to "cheat" and not find the answers out themselves using the ingame tools.

Anyway, I am brainstorming, I am not constraining the configuration space of possible games, I'm just pointing toward a section of it where it think it might be a good idea to start looking.
