"Why is it that SDO and RWA are bound together at the genetic level not only with policy attitudes, but also with two of the most relevant Big Five personality traits, agreeableness and openness to experience? We conjecture that the underlying reason for these patterns of results may be that the human selective context of resource competition likely affected fundamental personality variation (especially trait Openness), but also independent traits designed to deal with problems of hierarchy-navigation (RWA/SDO), and their downstream political correlates."

The genetic underpinnings of right-wing authoritarianism and social dominance orientation explain political attitudes beyond Big Five personality.
