Enough with the preliminaries! Are racial gaps in average IQ at least partly genetic?
A. Probably some are, but we don’t know for sure yet. At this point, we have a lot of data, and Occam’s Razor suggests the simplest and thus best explanation is that races differ in average IQ for the same reason that families differ. After all, races are just big extended families. But that might turn out to be wrong. We’ll know with a high degree of certainty fairly soon. Once we have a quite clear understanding of which genes affect IQ and by how much, it will be relatively trivial to then calculate the “expected IQ” for various racial groups based on their average genetic profiles.
