As a member of that pool of 51M I want to thank you for taking a complicated topic and making it easier to understand.  If I recall the Bell Curve talked about an American society being split into two groups, the university educated higher IQ and the lower educated blue collar workers which over time would associate less and less as they live in two totally separate enclaves.  And that that would have serious repercussions for American society.<br><br>What I also found funny was this discussion mentioned both Nazi intellectuals and Californa intellectuals in regards to the politizing of intelligence.  How ironical.  Great interview thanks Lex.
