Knudsen2019 finds that the emigration of 25% of the Scandinavian population to the USA 1850701920104ya was driven in part by more ‘individualistic’ personality factors among emigrants, leading to permanent decreases in mean ‘individualism’ in the home countries. This is attributed to cultural factors, rather than genetics. I model the overall migration as a simple truncation selection scenario, and find that in a simple model under reasonable assumptions, the entire effect could be genetic.
