A novel hypothesis posits that levels of genetic diversity in a
population may partially explain variation in the development and
success of countries.
This paper extends evidence on this novel question
by subjecting the hypothesis to an alternative context that eliminates
many alternative hypotheses by aggregating representative data to the
high school level from a single state (Wisconsin) in 1957, when the
population was composed nearly entirely of individuals of European
ancestry.
Using this sample of high school aggregations, the authors find a
strong effect of genetic diversity on socioeconomic outcomes.
Additionally, he authors check an existing mechanism and propose a new potential
mechanism of the results for innovation: personality traits associated
with creativity and divergent thinking.
