Diversity training doesn't extinguish prejudice. It promotes it.

A study of 829 companies over 31 years showed that diversity training had "no positive effects in the average workplace." Millions of dollars a year were spent on the training resulting in, well, nothing. Attitudes — and the diversity of the organizations — remained the same.

It gets worse..."In firms where training is mandatory or emphasizes the threat of lawsuits, training actually has negative effects on management diversity."

Why am I not surprised?
