Jonathan Haidt

American social psychologist — NYU Stern School of Business — author of The Righteous Mind, The Coddling of the American Mind, and The Anxious Generation — founder of Heterodox Academy — the most publicly prominent moral psychologist.

Creates Moral Foundations Theory — Haidt's framework (that human moral psychology is built on 6 foundations — care, fairness, loyalty, authority, sanctity, liberty — and that liberals use primarily care/fairness while conservatives use all 6) is the most empirically grounded explanation of why liberals and conservatives literally cannot understand each other morally.
