Sports Aptitude, a psychological firm that pertains to mostly professional athletes, is highlighted with their massive data pool of NBA players who are tested on their likeliness to succeed.  Much like the Meyers-Briggs test, the sports aptitude test simply portrays what they are named: how likely players are to succeed.  I find that basing athletic success solely on a test is a little odd, but they are claiming their test is significant.  Many Professional athletes have participated in the test, while most of them also are clients of Sports Aptitudes athletic psychologists.  This firm is truly groundbreaking, basing solely on the athlete.
