The average IQ of the world is projected to fall from 85.9 to 77.4 between 2023 and 2100, a total of 8.55 points.

The magnitude of the decline in IQ globally is about 1.1 point per decade between the years of 2023 and 2100, though the rate at which intelligence is declining is falling. When weighted by population, the magnitude of the decline within countries is 0.4 points per decade, so 36% of the global decline in IQ is within countries.

estimates were used from Becker’s national IQ dataset. We normalized the estimates from Patrinos and Angrist

to the distribution of national IQs which are found in
