The whole race and intelligence thing seems dopey to me. Let me say why.

If I want to help black people because more of them are poor than are white people, wouldn't it make more sense just to have a program that helps poor people?

If I won't hire black people because, on average (I believe) they are not quite as smart as white people, wouldn't I be better off just not hiring the individuals who seem dull to me? Wouldn't I be better off talking to each prospective applicant for a few minutes and hiring the individuals who seem smart regardless of their race? Any quantitative attempt to show a racial difference in intelligence shows that there are 100s of millions of black people who are smarter than 100s of millions of white people. Why use such a dopey standard?

Well, supposing I'm not quite smart enough to realize race is a really dopey proxy for the things I am really looking for. Is it immoral to use a dopey proxy, or merely stupid?

I don't think racism is caused by people thinking some race is inferior in some way. Rather the opposite, I think the statements of inferiority are a result of the racism, part of the mechanism one group uses to gain advantage over another in a social setting. Of course human minds being as recursive as they are, it is hard to unravel which comes first intellectually speaking.
