Two things:

1. Studies on the links between race and certain human characteristics. These include the various physical and mental indices catalogued by the eugenicists, and 'intelligence' as described by the authors of 'The Bell Curve.'

2. Studies on the link between attitudes and beliefs about race, and other social/political beliefs and behavior.

I was talking about the second sort of studies. But the bad repute of the first may have bled over to the second.
