What is the point in studying these racial differences in intelligence except to further racism? Haier acts like science is this socially neutral thing, as if he doesn't know it was used to fuel white supremacy consistently in the past. Give me a break... and if, say, Africans really are 10% worse at algebra and 10% better at rhythm... would we really benefit from tracking Blacks into music, or would we miss the next brilliant mathematician? Scientists should be free to choose what they want to study, but please choose something less stupid.
