Jonathan Haidt (pronounced “height”) is a social psychologist at New York University’s Stern School of Business. He received his Ph.D. from the University of Pennsylvania in 1992.

Haidt’s research examines the intuitive foundations of morality, and how morality varies across cultural and political divisions. Haidt is the author of The Happiness Hypothesis (2006) and of the New York Times bestsellers The Righteous Mind (2012) and The Coddling of the American Mind (2018, with Greg Lukianoff). He has given four TED talks. In 2019 he was inducted into the American Academy of Arts and Sciences. Since 2018 he has been studying the contributions of social media to the decline of teen mental health and the rise of political dysfunction. His most recent book is the New York Times #1 bestseller The Anxious Generation: How the Great Rewiring of Childhood is Causing an Epidemic of Mental Illness.
