Arguments in favor of an innate origin of political views are undoubtedly intriguing because of the strong correlations between certain traits of personality and corresponding politics, but — likely in a way unintended by proponents — these correlations may in fact imply a causality quite in the opposite direction. Even casual observation leads one to conclude that political views are largely heritable, if not from one’s family then certainly from one’s environment. We can see this heritability empirically in the tight geographic clustering of adherents by political conviction.

Given the largely random production of types of personalities at birth, and if views are correlated with traits of personality, then, it is the personalities that are shaped by the views rather than the other way around, and the genesis of cautious neat-freaks and impulsive artists owes more to milieu than to genes.
