In this link you can find the schocking results of a study* regarding racial and gender discriminations in Universities. The researchers emailed 6500 professors pretending to be students. The mails contained the same message but a different name in order to signal a different gender and race (i.e. Black, Hispanic, Chinese, Caucasian). Women and minorities had a significantly lower response rate (25% gap) than white males. Discrimination is high in business (25%) schools but lower in humanities (5%). For engineering the gap was 13%. Another interesting result was that for fine arts there was a -11% reverse discrimination. You can find more information and all the results in the study (follow links provided).
