There is nothing either good or bad, but thinking makes it so. - Jonathan Haidt

Reciprocity is a deep instinct; it is the basic currency of social life.

Religions are moral exoskeletons. If you live in a religious community, you are enmeshed in a set of norms, relationships, and institutions that work primarily on the elephant to influence your behavior. But if you are an atheist living in a looser community with a less binding moral matrix, you might have to rely somewhat more on an internal moral compass, read by the rider. That might sound appealing to rationalists, but it is also a recipe for anomie — Durkheim’s word for what happens to a society that no longer has a shared moral order.63 (It means, literally, “normlessness.”) We evolved to live, trade, and trust within shared moral matrices. When societies lose their grip on individuals, allowing all to do as they please, the result is often a decrease in happiness and an increase in suicide, as Durkheim showed more than a hundred years ago.

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.
