Rather, it would suggest that collectivism was «stickier», representing a better fit in populations with a high proportion of
putative social sensitivity alleles (Lieberman, 2009).
Again,
the putative social sensitivity allele, the G allele, was more prevalent in populations with greater collectivism.
Given that there is a higher prevalence of
these putative social sensitivity alleles in East Asian populations than in Caucasian populations, there may be a relationship between the relative proportion of these alleles and the predominant cultural forms in a population.
Here, we review recent work that has demonstrated a robust cross-national correlation between the relative frequency of variants in these genes and the relative degree of individualism — collectivism in each population, suggesting that collectivism may have developed and persisted in populations with a high proportion of
putative social sensitivity alleles because it was more compatible with such groups.
