I met Greg five years ago. The first words out of his mouth were: "You've done a terrible thing." Not really fair. It had only been a minor political infraction — mathematically speaking. Besides, I hadn't known Greg at the time.
I had known of Greg before then. There was a bizarre article that I had read about Ashkenazi Jews over at Jerry Pournelle's web site. The author was Greg Cochran. It was full of strange arguments about genetic drift, rare diseases, medieval history, and brain genes. This was science fiction. It was also very compelling. I'm a fairly skeptical individual, but I thought that maybe there was something to this idea. In fact, the research was later published in the Journal of Biosocial Science in 2005.
And that wasn't his only scientific idea. Not by a long shot.
Greg is a physicist, but has done most of his recent research in genetics. When pressed, he will deliver a variation of the quote on the right to explain his choice of fields.
Now, one of the most frustrating things I know about Greg is that he seems completely unwilling to devote time to a web site of his own. After a long period of needling, I finally gave up and created this site to show the internet what I've been up against all this time.
