A nation’s IQ correlates negatively with its average temperature. But the most impressive inverse correlation is with a country’s estimated temperature during the Würm glaciation between 30,000 and 11,700 years ago: -.87.
This supports the theory that higher intelligence evolved in the European and Northeast Asian peoples because of its survival benefits in colder latitudes during that most recent ice age.
