Genetics and culture are not independent variables, Mike.
Can you confidently state the connection between the Irish and politics is entirely cultural? Can you confidently state the connection between orientals and Jews and academic achievement is entirely cultural? Can you confidently state the connection between Jews and the award of Nobel prizes is entirely cultural? Can you confidently state the connection between being female and creating children is entirely cultural? Can you confidently state that the connection between Blacks and basketball/football/100-yard-dash performance is entirely cultural? Can you confidently state that the reason 97% of all pilots are male is entirely cultural? Can you confidently state that the reason why all geniuses are male is entirely cultural. Can you confidently state the reason that the top 120 composers of music (from the Renaissance to the present) are male is entirely cultural? Can you confidently state that the reason the top 100 sculptors, painters, and dramatists are male is entirely cultural? Can you confidently state that the reason for the different shapes of the male and female IQ distributions, and different IQ averages for males and females, is entirely cultural? I could go on and on.
It is true that “politically correct” egalitarianism requires that there be no genetic component to anything. But the presence of that requirement does not prove there is no interaction between genetics and culture.
There is a lot of science proving there are substantial genetic determinants to cultural variables, Mike.
