He also notices an interesting interplay:
Self-assessed IQ seems to be inversely related to actual IQ.He arrives at this observation from the insight on elevated black self-perception and also on the seeming inverse relationship between national pride (as measured by the percentage of a country's populace who say they are "very proud" of their nationality) and actual reasons for pride across more than seventy countries.
A nation's average IQ as estimated by Lynn and Vanhanen in IQ and Global Inequality is by no means a perfect proxy for achievement, nor should national pride be tied directly to it. But the relationship between pride in one's nationality and that nation's average IQ is interesting in that it is so robust. The two correlate inversely at .61 (p=0).
The most prideful populations are not only those of the most modest intelligence, they also comprise the youngest nations. As average IQ and median age are inversely correlated at .83 (p=0), it comes as little surprise that national pride and median age inversely correlate at .63 (p=0). These young, confident societies are the nations of tomorrow.
Crudely, the future looks like one in which humans, at least on a per capita basis, think more highly of themselves while pulling off less than they have in the past.
