I had previously noted that Gregory Cochran had not attacked geneticist Adam Rutherford in Cochran's West Hunter blog, as he had attacked anthropologist R. Brian Ferguson, but I should have known better than to assume Cochran had refrained from attacking Rutherford at all.
When Steve Sailer, who considers Cochran a friend, was celebrating the work of Cochran and Harpending, he compared them to Darwin. Cochran compared his own work to that of Einstein.
Ron Unz, benefactor of both Cochran and Sailer, may be a kooky Holocaust-denier, but he's right about Cochran: "...he believes he’s far, far smarter and more knowledgeable than he actually is. This serious personal flaw leads him to make all sorts of grandiose claims regarding topics in which he knows absolutely nothing and therefore looks ridiculous."
While Googling for something else, I discovered that Cochran had indeed insulted Rutherford too, way back in February 2020, as we can see in his tweet response to evolutionary psychology creep Geoffrey Miller.
So Cochran feels intellectually superior to both Ferguson and Rutherford. Rutherford doesn't appear to be too impressed though.
