While I agree with some elements of that line of thinking, I also think that surfacing latent biases can help us to double-check some of our "gut reactions", particularly in high stakes situations (hire/fire/promote as just one example).

I do not believe in any form of quotas or similar affirmative action items, but if I am sub-consciously biased against someone, I'd rather know that, so I can make an attempt (which will still have some bias) to make a fact-based decision.
