“When it comes to moral judgments, we think we are scientists discovering the truth, but actually we are lawyers arguing for positions we arrived at by other means.” The surprising psychology behind morality is at the heart of social psychologist Jonathan Haidt’s research. He explains “liberal” and “conservative” not narrowly or necessarily as political affiliations, but as personality types — ways of moving through the world. His self-described “conservative-hating, religion-hating, secular liberal instincts” have been challenged by his own studies. This interview is edited and produced with music and other features in the On Being episode “Jonathan Haidt — The Psychology of Self-Righteousness.” Find onbeing.org.
