Jonathan Haidt is an American social psychologist known for his work on moral psychology, political polarization, and the moral foundations framework. He has held faculty positions at major research universities and has written books and essays that bridge academic research and public debate. Haidt's work has influenced scholarship across psychology, political science, philosophy, and public discourse, provoking both adoption and critique from scholars and commentators.

Early life and education

Haidt was born in New York City and raised in suburban New Jersey. He completed undergraduate studies at the University of Pennsylvania, where he studied under faculty in psychology and related departments. He earned a Ph.D. in psychology, conducting doctoral research that intersected with work from scholars at Harvard University, Yale University, and the University of Chicago on moral reasoning and emotion. During his graduate training he engaged with theoretical and empirical traditions influenced by figures associated with Lawrence Kohlberg and Carol Gilligan, while also interacting with contemporary researchers at the American Psychological Association conferences.

Academic career and positions

Haidt joined the faculty at the University of Virginia where he became a full professor in the Department of Psychology and a member of affiliated centers. He later served as a professor at the New York University where he interacted with scholars in social psychology and political science, and as a visiting scholar at institutions including Princeton University and research centers connected to the Russell Sage Foundation. He cofounded and directed research initiatives and centers that partnered with funders such as the John Templeton Foundation and foundations supporting interdisciplinary research. Haidt has taught undergraduate and graduate courses, supervised doctoral students, and participated in panels alongside academics from Stanford University, Massachusetts Institute of Technology, and Columbia University.

Research and theories

Haidt is best known for developing Moral Foundations Theory, a multi-foundational account proposing innate psychological systems that shape moral judgment. The theory identifies several foundations—care/harm, fairness/cheating, loyalty/betrayal, authority/subversion, sanctity/degradation—and later additions debated in the literature, engaging scholars from Jonathan Haidt's contemporaries to critics at Rutgers University and University of California, Berkeley. His approach draws on evolutionary psychology traditions linked to work by Charles Darwin, William James, and modern researchers affiliated with E. O. Wilson's influence. Haidt advanced the social intuitionist model arguing that moral judgment is often driven by intuitive processes followed by post hoc reasoning, engaging debates with theorists such as Lawrence Kohlberg and Joshua Greene. He has applied his models to explain ideological differences among supporters of political movements and parties, comparing moral profiles across partisans in contexts studied by researchers at Pew Research Center and think tanks including the Brookings Institution and the Cato Institute. Haidt's empirical work employed cross-cultural surveys and collaborative projects involving teams at University of Cambridge, University of Oxford, and institutions in Asia and Latin America, prompting responses from scholars at Princeton University and Yale University about measurement validity and cross-cultural interpretation.

Publications and popular works

Haidt authored several books and numerous peer-reviewed articles. His major works include a book that synthesizes moral psychology for broad audiences and addresses political polarization, drawing attention from media outlets and academic reviewers associated with The New York Times, The Atlantic, and Scientific American. He published in journals where scholars from American Psychological Association divisions and editors at Nature Human Behaviour participate. Haidt's writings have been translated and cited by researchers at Harvard University Press and academic publishers, and his public-facing essays appeared on platforms frequented by commentators from The Washington Post and The Wall Street Journal.

Public engagement and controversies

Haidt has been an active public intellectual, participating in panels, podcasts, and testimony before commissions and institutions such as committees that host scholars from Harvard Kennedy School and the American Enterprise Institute. He cofounded initiatives addressing campus climate and free speech that involved collaboration and debate with administrators from Yale University and University of California campuses. His advocacy about ideological diversity, social media effects, and university governance generated controversy and critique from scholars at University of Michigan and activists associated with student organizations at Columbia University and University of California, Berkeley. Critics from journals and blogs tied to The Chronicle of Higher Education and left- and right-leaning commentators questioned his interpretations of data, while supporters from conservative and centrist outlets defended his emphasis on institutional reform. Debates extended to methodological disputes involving replication researchers affiliated with the Open Science Framework and statisticians at Stanford University.

Awards and honors

Haidt has received fellowships, research grants, and visiting appointments recognizing interdisciplinary contributions, including awards supported by philanthropic organizations such as the John Templeton Foundation and honors from psychology and interdisciplinary associations connected to the Society for Personality and Social Psychology and regional scholarly societies. His work has been cited in award committees and academic recognitions at institutions like Princeton University and New York University for influence on public understanding of moral psychology.
