Abstract:
|
In the years since Jackie Robinson broke the "color barrier" in baseball, overt racism has become socially unacceptable in mainstream American society. However, more subtle patterns of discrimination persist. Baseball provides a convenient laboratory for examining the extent to which discriminatory behaviors remain, even at the subconscious level. We examine pitch-by-pitch data for the 1989 through 2010 major league baseball seasons. We focus on the umpire's subjective decision as to whether a pitch is called a ball or strike. We find that the pitcher's and hitter's race have a small, inconclusively significant, effect upon the outcome of that call.
