This is the bailey in the motte-and-bailey defense of diversity. Of course people from different backgrounds will contribute differing perspectives. But in practice, it always ends up being race, gender, and sexual orientation. No talk about getting representatives from groups that actually think in ways that are different. Where are the quotas for libertarians, green party members, immigrants, aspies, former attorneys, artists, competitive athletes, scoutmasters, stamp collectors, gearheads, all shades of personality types?

Spot on. While the idea behind can be interesting, it is implemented by accepting people who have the same "social status" background (same schools, same opinions), but are of different gender/race.

I think that a white factory worker could add way more insight into how other communities views things, than hiring a black/female attorney does...

Having said that, I'm really afraid what the backlash against this type of diversity-thinking will be. The system will surely corrects itself in the future (it's already starting), but I'm not certain going back to another extreme would be very wise...
