Let me note that what is correlated with badness may be more the fact of speaking racist beliefs, not of 'having them' -- the latter is hard to collect info about, absent mind-reading technology.
True, though in general I don't think we have much trouble discovering the unspoken beliefs of other people through their behaviors. I grant of course that if a racist belief has no relationship to someone's behavior whatsoever, then it cannot be the cause of being a bad person (since this seems to be very much an issue of behavior).
But in such a case, I think serious questions could be raised about whether or not this belief is actually a belief the person holds.
