Implicit Assumptions test: just blow the whistle

Interesting article in today's NYT: a statistical analysis of NBA officiating (by 2 economists).

The bottom line: "We find that black players receive around 0.12-0.20 more fouls per 48 minutes played (an increase of 2.5-4.5%) when the number of white referees officiating a game increases from zero to three.”

It's rather fantastic that one can quantify prejudice.
