Brian Leiter has finally said something about Evolutionary Psychology that is more than just quick verbal jab. He did so in the update to this post. Note that the update is many times longer than the original post. I like it when people back up their claims with arguments. Maybe Leiter will do it more often, now.
If you're familiar with Gould's critique of EP, then you probably don't need to read Leiter's post (though there are some interesting facts in it), because it's pretty much the same thing. Interestingly, Buller, whom Leiter has mentioned favorably in the past, spends some time in his book arguing that this line of attack (the "we can't just assume it's an adaptation" line) is a critique that is neither fair to EP, nor extremely damaging to it. It will be interesting to see whether Leiter, in the article on biology in law that he says he is writing, references Buller or some of the replies to this critique by Evolutionary Psychologists. For the most part, on the biological side of things, I'd prefer to take Buller's approach, which, by the way, also notes that EP is woefully poor biologically (and neuroscientifically, and methodologically, and cognitively, and so on).
UPDATE: I should have noted that Leiter's arguments are more than those of Gould. Tacked on are those of Elisabeth Lloyd. I mention this mostly to post a link to her very good paper on EP, which you should read.
