An important dictum of cultural psychology is that each culture develops expertise in some aspects of human existence, but no culture can be expert in all aspects. The same goes for the two ends of the political spectrum. My research3 confirms the common perception that liberals are experts in thinking about issues of victimization, equality, autonomy, and the rights of individuals, particularly those of minorities and nonconformists. Conservatives, on the other hand, are experts in thinking about loyalty to the group, respect for authority and tradition, and sacredness.4 When one side overwhelms the other, the results are likely to be ugly. A society without liberals would be harsh and oppressive to many individuals. A society without conservatives would lose many of the social structures and constraints that Durkheim showed are so valuable. Anomie would increase along with freedom. A good place to look for wisdom, therefore, is where you least expect to find it: in the minds of your opponents. You already know the ideas common on your own side. If you can take off the blinders of the myth of pure evil, you might see some good ideas for the first time.

If you think that moral reasoning is something we do to figure out the truth, you’ll be constantly frustrated by how foolish, biased, and illogical people become when they disagree with you. But if you think about moral reasoning as a skill we humans evolved to further our social agendas — to justify our own actions and to defend the teams we belong to — then things will make a lot more sense.
