The thing is I know the author, David Sirota:
Today, Major League Baseball games using QuesTec's computerized pitch-monitoring system are the most statistically quantifiable workplaces in America. Match up QuesTec's accumulated data with demographic information about who is pitching and who is calling balls and strikes, and you get the indisputable proof of how ethnicity does indeed play a part in discretionary decisions of those in power positions.
This is exactly what Southern Methodist University's researchers did when they examined more than 3.5 million pitches from 2004 to 2008.
Their findings say as much about the enduring relationship between sports and bigotry as they do about the synaptic nature of racism in all of American society.
