I doubt he would want to discuss given the ordeal he went through in the past, but Brett Weinstein who has been on Glenn's podcast in the past as briefly talked about this issue. He has a Q&A and received a question about racial group disparity in testing and whether its largely caused by genetics. He basically said as an evolutionary biologist this question was up his ally and there is not sufficient evidence to conclude that test score differences are derived from genetics. He said it remains an open question--and given that nobody really wants to research the question in a thorough scientific way, its likely to remain an open question for a long time. But he said people who have reached conclusions (such as Charles Murray though I don't think he called him by name) have reached conclusions about a causal relationship before the evidence really proves that.

I think I heard that same episode. Right when it was getting interesting, he moved to the next question.
