What do you think about the new study which claims Black-White IQ gap has decreased over the last thirty years? One big problem is the the IQ gap seems to widen as Blacks get older (see Figure 3 and the text: from 12 to 15, the Black IQ shrinks from 90.5 to 88.8, and by 24, it's down to 84.5). This is consistent with other nations. For example, the British racial gap expands from .24 to .77 standard deviations when comparing 7 to 15 year olds. This trend has also been observed in adoption research and Head Start follow up reports: early gains are practically erased by 15. What's disturbing about these observations is that the racists claim that Blacks develop earlier than whites, and that the IQ gap should therefore widen over time. Now I would expect some widening during early adolescence, but then the gap should close again as the individuals begin to slough off their early environmental influences. This, apparently, doesn't happen.
Yet the gap has shrunk by 5 points across all age groups.
Should we be optimistic?
