(last piece of the puzzle)

—“Existing literature connects military service to regional characteristics and family traditions, creating real distinctions between those who serve and those who do not. We engage this discussion by examining military service as a function of personality. In the second portion, we examine military service as predisposed by genetics. Our findings indicate there is a significant heritability component of serving in the military. We find a significant genetic correlation between personality traits associated with progressive political ambition and military service, suggesting that military service represents a different form of political participation to which individuals are genetically predisposed. We discuss the long-term implications of our findings for policy makers and recruiters.”—
