Jonathan Haidt is a social psychologist and professor at New York University's Stern School of Business. His early research was on morality, emotion, and culture, but since 2018 he has been studying the contributions of social media to the decline of teen mental health and the rise of political dysfunction. He is the author of The Happiness Hypothesis and of three New York Times bestsellers: The Righteous Mind, The Coddling of the American Mind (with Greg Lukianoff), and the international bestseller The Anxious Generation. His goal is to help young people and democracies flourish in the digital age.
