Study Finds Racial Bias in NBA Officiating
by
findingDulcinea Staff
A recent study of NBA players’ statistics suggests that referees call more fouls on players of a different race than themselves, prompting the NBA to issue a fierce refusal of these findings and raising the broader issue of racism in professional sports.
30 Second Summary
NBA officiating is racially biased, according to a recent academic report.
University of Pennsylvania assistant professor Justin Wolfers and Cornell University graduate student Joseph Price have completed a study that they say reveals a racial bias in how referees officiate professional basketball games.
By analyzing every game’s box score over a 13-season period through 2004, the two men found that the racial composition of the officiating crew influenced foul calls by up to 4.5 percent.
The NBA has criticized the study, refuting it with a study of its own that NBA commissioner David Stern said is “more powerful, more robust, and demonstrates that there is no bias.”
However, the NBA recently offered Wolfers the chance to review the data they’ve collected, and he contends that it only confirms his original findings.
The study stresses that it does not imply intentional racial bias, but should be seen as part of a growing body of studies examining elements of subconscious racism known as “implicit association.”
Whether the report finds credence in the athletic community or not, the controversy’s drawn renewed attention to the racial history of professional sports, even as baseball finishes celebrating Jackie Robinson’s breaking the color barrier.

Wolfers and Price’s study not only accounts for factors like players’ positions, playing time, and their status as an All Star, but also takes into account the fact that there are more African American players in the league than any other ethnic group.

Justin Wolfers has been allowed to look at the data collected by the NBA’s own internal study, and rather than proving that the league’s officiating is bias-free, he says their data “agrees with our own conclusion: A referee is more likely to blow the whistle and call a foul against a player of another race.”

Reactions
The NBA responded to the New York Times’ report about the study with anger. League president of basketball operations Joel Litvin said “the story is based upon a paper that is flat-out wrong in its conclusions, and we're disappointed that they ran the story this way.”
