My early research - I'm a social psychologist, and my early research was on how people make moral judgments. When I entered the field in 1987, everybody was looking at moral reasoning - how do kids reason about a moral dilemma? Should a guy steal a drug to save his wife's life?
Democrats talk about programs like Social Security or Medicare, but it's not clear to most voters what Democrats' core moral values are.
Social conservatives are very focused on strengthening the family, and I think they are right to do so. One of the worst blind spots of the Left has been its reluctance to say that marriage matters for children.
Liberals are my friends, my colleagues, my social world.
Social reality is so complicated that, once you join one team or the other, you become specialized in detecting certain patterns, but you become blind to other patterns.
Reciprocity is a deep instinct; it is the basic currency of social life.
Most of our social nature is like that of other primates - we're mostly out for ourselves.
