Average IQ by Country. This explains an awful lot about the world. Look how well it maps onto economic development, which in turn maps onto population growth. (As a result, the world average IQ is falling quite rapidly at the moment.)
These numbers came from a work carried out from 2002 to 2006 by Richard Lynn, a British Professor of Psychology, and Tatu Vanhanen, a Finnish Professor of Political Science, who conducted IQ studies in more than 80 countries. Differences in national income are correlated with differences in the average national intelligence quotient (IQ). They further argue that differences in average national IQs constitute one important factor, but not the only one, contributing to differences in national wealth and rates of economic growth.
This knowledge has been suppressed by the politically correct and the left generally for decades, for obvious political reasons.
IQ correlates well and positively with income, but well and negatively with criminality — much better than education, which suggests that education only has these correlations because it is a proxy for IQ nowadays. But the left worldwide furiously denies that IQ exists or that it matters, and figures that giving people more education, including a university education, makes them more economically productive and less likely to be criminals — no, not much, beyond a base level that we passed in the west decades ago. Mass university education is a cargo cult of the left. Another example of a large waste of time and money because the politically correct deny reality. Damaging too, because universities have dumbed down to accommodate large numbers of less-bright students.
Beyond a reasonably stimulating environment and decent diet and health, nothing people have tried has any significant effect on IQ in the long term — it is mainly a genetic outcome. A bell curve results because it is a somewhat additive effect of about 500+ genes, apparently.
It seems that this knowledge about IQ is escaping into the population, via the Internet. The media of course, being politically correct, won’t have a bar of it — but I’ve noticed it is starting to seep in.
By the way, I haven’t seen any maps of the standard deviations in IQ, which are also relevant economically because they help determine the numbers of people at the ends of the bell curve.
