It’s too bad he doesn’t regularly blog at some fixed spot, I never would have known about this post at the Straight Dope forums if it hadn’t been mentioned in a comment at GNXP classic. It’s about his famous paper with Henry Harpending on the natural history of Ashkenazi IQ. I recall it being rather favorably received by the press (I believe it was a Newsweek cover, and Steve Pinker gave a popular talk), but by Cochran’s account a lot of academics wouldn’t touch it with a ten-foot pole.

Steve Hsu’s Google Tech Talk on the BGI IQ study is here. BGI was one of the organizations that turned down Cochran & Harpending*.
*I gave an inaccurate account. See Henry Harpending’s comment below.
