Today's post, Rational vs. Scientific Ev-Psych was originally published on 04 January 2008. A summary (taken from the LW wiki):
In Evolutionary Biology or Psychology, a nice-sounding but untested theory is referred to as a "just-so story", after the stories written by Rudyard Kipling. But, if there is a way to test the theory, people tend to consider it more likely to be correct. This is not a rational tendency.
Discuss the post here (rather than in the comments to the original post).
This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Stop Voting For Nincompoops, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki. Go here for more details, or to have meta discussions about the Rerunning the Sequences series.
One of the major challenges to evo-psych hypotheses about gender is never really tackled in the original comment thread: that women and men are conditioned differently in almost all current and historical societies, so it's almost impossible to differentiate effects of training from inborn psychological phenomena.
Basically: if you're the one who's always been expected to put the groceries away, do the cooking, and set the table, you've probably developed a pretty good strategy for getting the damn ketchup out of the fridge.
Of course, we could always argue that women are almost always socialized for these roles because they have an evolution-granted knack for them, but then we'll be tasked with finding a large enough (and representative enough) population that hasn't had any of that conditioning.
