Of course, if IQ were just a delusion of white male privileged racists, it would be hard to explain how test scores could be forecast from brain scans. Slowly, however, that’s becoming more feasible to accomplish.

blog a draft of his paper on “The general brain factor, working memory, parental income and education, and racial admixture
James Thompson at Psychological Comments
has thoughts on Kirkegaard’s analysis here
