Moderates and conservatives were adept at guessing how liberals would answer [moral] questions. Liberals, especially those who described themselves as “very liberal,” were least able to put themselves in the minds of their adversaries and guess how conservatives would answer.
… For liberals, morality is largely a matter of three values: caring for the weak, fairness and liberty. Conservatives share those concerns (although they think of fairness and liberty differently) and add three others: loyalty, respect for authority and sanctity.
Another way of putting it is this: Americans speak about values in six languages, from care to sanctity. Conservatives speak all six, but liberals are fluent in only three.
This actually speaks to a position I’ve been taking in classes for about 20 years. In economics, I stress that the end result of helping the weak is a central goal of most politics, and that liberty is economically beneficial.* And I emphasize that it is a mistake to think about policy decisions made by different groups as differing on these points; I’ve never felt that they did.
* I also emphasize that economics doesn’t have much to say about fairness.
