Nature or Nurture? The Rick Ratchford question? Well, yes, but also the question at the heart of the Turtle Trader Experiment.

"What are the turtles? In the fall of 1983, Dennis (Richard Dennis) bet his then partner William Eckhardt that he could teach beginners with no experience how to trade to make millions in the same way he had. His partner scoffed saying that great traders were born, not bred. The two men decided to find out who was right. They hired and trained students -nicknamed the Turtles (the name came after Dennis visited a turtle breeding farm and decided to grow traders like they grew turtles)."-Michel Covel-Article-The Legend of the Turtle Traders-SFO-Stocks, Futures and Options Magazine-August 2007
