Cosma Shalizi has put up a gigantic post on IQ & heritability; he originally titled it “Duet for Leo and Razib,” implying that I, and the audience here @ Gene Expression, are the targets of his eloquence (at least in part). Now, I have to admit something, I’m not really interested in psychometrics that much anymore. It has been a while since I have been, stupid people are obviously stupid and I am not interesting in debating that fact. I take my own opinions in this area as background assumptions, so I’m not going to respond to Cosma. In fact, I won’t read the post right now, there’s some interesting stuff on HLA & heterozygosity that I want to check out! But, I do invite readers to digest what Cosma is saying, because I guarantee you that you’ll see it replicated by lesser minds elsewhere.
