IQ stats supported?

Can of worms. The book "The Bell Curve" by by Richard Herrnstein and Charles Murray is seriously politically incorrect, and so various leftist "scientists" have tried to "correct" it. Who knows, maybe some of their claims are true.

FWIW I tend to believe Charles Murray and to distrust everyone else.
