The Flynn effect is within a single population.
Intelligence varies between populations, and the ratio changes, eg European IQ probably dropped from 1930-1945 due to genocide of a high IQ population.
Some places are growing much faster than others, eg Europe had twice the population of Africa in 1950 and soon it will have half.
So both groups got smarter, but the global average dropped.
Going forward things don't look good, the highest IQ countries like Singapore and South Korea have ~1 TFR so are on track to halve in size each generation (against a growing world)
