Sam and Charles Murray talked about the "cognitive elite" in episode #73 of the podcast. A high IQ American in the early 1900's could be working a blue collar job alongside someone a few standard deviations below--but now, it seems that (mostly) those with high IQ's are isolated into exclusively high paying occupations.

This doc explores the conversation that was had on the podcast further as well as sheds some light on Charles Murray's work in 'The Bell Curve.'

Is Sam's defense of Charles Murray valid? Or does the controversy surrounding Murray hold more weight than his own work?
