The wealth of nations is mapped by their IQ (Times Online). The argument runs this way. High-IQ nations have higher standards of living while lower-IQ nations have lower living standards. IQ is heavily influenced by diet and health. Hence, prosperous nations should subsidize health and diet in less prosperous nations.
Researchers (professors of psychology and political science) seem to have overlooked a more obvious consideration: economic freedom. Rising IQs don’t account for the dramatic change in living standards in China, for example, between 1980 and today.
