Prior work has established robust diversity in the extent to which different moral values are endorsed. Some people focus on values related to caring and fairness, whereas others assign additional moral weight to ingroup loyalty, respect for authority and established hierarchies, and purity concerns.

Individuals differ in their support for social change. We argue that examinations of inequality and change would benefit from consideration of underlying personality processes. New data suggest that Right-Wing Authoritarianism and Social Dominance Orientation, indicators of support for inequality, may be motivated by biologically driven personality processes, particularly those related to posit...

We tested the association between a biomarker of early sex differentiation, the second-to-fourth finger length ratio (2D:4D), and unprovoked attack during a simulated war game (n = 176). We also investigated whether 2D:4D mediated the tendency for men to attack more than women and whether personality dimensions previously associated with sex differences in aggression or hostility (social domina...

As predicted, authoritarianism strengthened support for the attack by intensifying the perception that Iraq threatened America. So...
