I'm somewhat frustrated by the frequent posts warning us about the dangers of Ev. Psych reasoning. (It seems like we average at least one of these per month).

It seems like a lot of this widespread hostility (the reaction to Harald Eia's Hjernevask is a good example of this hostility) stems from the fact that ev. psych is new. New ideas are held to much higher standard than old ones. The early reaction to ev. psych within psychology was characteristic of this effect. Behaviorists, Freudians, and Social Psychologists all had created their own theories of "ultimate causation" for human behavior. None of those theories would have stood up to the strenuous demands for experimental validation that Ev. psych endured.

Evolutionary theories get mentioned a lot on this site, and I frequently feel that they are given far more weight than would be warranted. In particular, evolutionary theories about sex differences seem to get mentioned and appealed to as if they had an iron-cast certainty. People also don't hesitate to make up their own evolutionary psychological explanations.

I just don't think this is true. People do lots of hypothesis generation on LW, using many explanatory frameworks, and I see no reason to believe that Ev. Psych explanations are more overconfident.
