No joke. Video is here, GNXP post is here and here. Back when I used to comment at bhtv I remember asking for them to have on John Derbyshire or even (when hell freezes over) Steve Sailer. I certainly didn’t expect this, which is even better. That was of course before I knew Cochran & Harpending were working on a book. Razib has elsewhere stated that he’s impressed by Reihan Salaam’s ability to toss off facts from the top of his head, but both he and Greg outdid him here.
