Yeah, racial IQ differences are really popular amongst a certain class of well educated "I'm just pointing out uncomfortable truths" kind of person. And don't get me wrong, I have no problem with uncomfortable trths if they're actually true.

But the thinking on this issue is oddly shallow. Acknowledging disparities is all well and good. But there's surprisingly little thought about why thoise disparities exist. Or why they change over time. Some people simply can't bring themselves to admit that chutzpah isn't the only determining factor in success.
