I've looked into it a little before and couldn't find anything except research supporting a race-IQ correlation. I've heard rumors of cultural bias in tests but didn't find actual research. There does seem to be an economy factor though because countries with racially similar people tend to have different IQs in relation to their economic performance. I think this is the biggest and most widespread misunderstanding the moderate left (ie not communists) has about the world. My theory is that people are afraid the general public doesn't have the education or self-discipline necessary to know this information (even if it's wrong!) without turning into violent racists. Black slavery used to be justified by "they're inferior so it's OK to treat them badly", and the left countered the first part of that but not the second. It's entirely possible that they are, on average, inferior intellectually but that doesn't justify abusing them. How can you let that genie out of the bottle though without people making blanket judgments of entire races? Just in case anyone thinks I'm a white supremacist, it's not whites at the top, it's Asians and Ashkenazi Jews.
