I don't think the view that there are genetic racial differences in IQ is popular here, if that's what you're referring to. It's come up a few times and the consensus seems to be that the evidence points to cultural and environmental explanations for the racial IQ gap.

I was wondering about that too, it's not really a a major topic here, though maybe the fact that it's been recently discussed on Overcoming Bias and that Roissy in DC is a "nearby" blog gave him this impression?
