Bio

A Professor Emeritus at Williams College in Massachusetts, Saul Kassin joined the John Jay faculty as Distinguished Professor of Psychology in 2006. Starting in the 1980s, he pioneered the scientific study of false confessions. Kassin is former president of the Psychology-and-Law Division of the American Psychological Association (APA); the lead author of its Official White Paper on false confessions, which is currently being updated; and the recipient of lifetime achievement awards from APA, APS, AP-LS, EAPL, and iiiRG.  He has appeared as an analyst on all major news networks and in several podcasts and documentaries, including Ken Burns’ 2013 documentary, The Central Park Five. Over the years, Kassin has consulted in several high-profile cases. His work, which was featured in SCIENCE Magazine (Starr, 2019), is newly presented for policy makers and laypeople alike in his 2022 book, titled DUPED: Why Innocent People Confess – And Why We Believe Their Confessions.
