New York — A 2007 study on race and refereeing in the NBA has resurfaced in a respected journal. ESPN Reports:
Basically, the more black referees on the court, the better the calls for black players. And the reverse is true for white players. The entire combined effect is fairly limited, around 4 percent, but the pattern is certainly there.
All of this means not all that much about NBA referees, other than that they’re human. The research was about human decision making in the workplace, and the referees were just a handy group to study.
