MILKMAN: There's absolutely no benefit seen when women reach out to female faculty, nor do we see benefits from black students reaching out to black faculty or Hispanic students reaching out to Hispanic faculty.

GREENE: So any idea why all of these faculty members are discriminating between students?

VEDANTAM: Milkman found there were very large disparities between academic departments and between schools. Faculty at private schools were significantly more likely to discriminate against women and minorities than faculty at public schools. And faculty in fields that were very lucrative were also more likely to discriminate. So there was very little discrimination in the humanities. There was more discrimination among faculty at the natural sciences. And there was a lot of discrimination among the faculty at business schools. Here's Milkman again.

MILKMAN: The very worst in terms of bias is business academia. So in business academia, we see a 25 percentage point gap in the response rate to Caucasian males vs. women and minorities.
