"Dennis and Eckhardt knew long- term trading success did not correlate one- to- one with high IQs. They were trying to assess the applicants’ ability to think in terms of odds—the same kind of thinking needed to win at blackjack in Las Vegas. And they wanted applicants with the emotional and psychological makeup to treat money abstractly so they could focus on how to use it as a tool to make tons more."

The above is a quote from The Complete Turtle Trader.

Given that they had a selection process rather than choosing applicants at random can they truly have been said to prove/disprove the nature/nurture question?
 
What does thinking in terms of odds and abstract money treatment has to do with nature/nurture?
