"Basically, there is no indication that people with higher IQ are able to reach the top faster. We are finding people who meet the criteria for being skilled surgeons, chess masters, athletes or magicians. Once you start looking at what makes them successful, IQ doesn't make any difference."

Hogwash. While IQ is no guarantee of success, how would a city look that had "skilled" surgeons of average or below intelligence? Chess masters? Uh huh. Sure. Athletes? Sorry, I'm not aware that athletics have anything to do with intelligence. Magicians? Shall I laugh now?

Hmmm... it's not April Fools day yet.
