““The conventional wisdom is that political orientations are primarily shaped by political socialization (e.g., parents, teachers, peers, etc). We find that the sense of civic duty is heritable and also that there is genetic overlap between personality traits (which we, and many psychologists before us, find to be heritable) and civic duty.”
By statistically analyzing data from twins who had participated in the National Survey of Midlife Development in the United States, the researchers found evidence that people have different heritable predispositions to how they feel about politics.
Specifically, they found that about 70% to 87% of the relationship between civic duty and four of the Big Five personality traits could be attributed to genetic factors. (The four personality traits being Extraversion, Conscientiousness, Emotional Stability, and Openness.)
