Mostly agreed, but I'd suggest that, instead of The Bell Curve- which is full of highly questionable and mostly-discredited pseudoscience- you instead read Stephen Jay Gould's "The Mismeasure of Man". The most recent edition, I believe, has an entire chapter devoted to dissecting exactly what's wrong with the arguments presented in "The Bell Curve".
