Saul Kassin is Distinguished Professor of Psychology at John Jay College of Criminal Justice, in New York City. He received his Ph.D. at the University of Connecticut after which he spent most of his career at Williams College. At various times, he was a postdoctoral research fellow at the University of Kansas; a U.S. Supreme Court Judicial Fellow at the Federal Judicial Center; and a postdoctoral fellow and visiting professor in the Psychology and Law Program at Stanford University.
Dr. Kassin is author with Steven Fein and Hazel Markus of the textbook Social Psychology (11th edition), published by Cengage Learning. He has also authored an introductory psychology textbook and written or edited several scholarly books, including: Confessions in the Courtroom, The Psychology of Evidence and Trial Procedure, The American Jury on Trial: Psychological Perspectives, and Developmental Social Psychology.
In his research, Dr. Kassin uses social psychology for the identification and prevention of wrongful convictions. Starting in the 1980’s, he pioneered the scientific study of false confessions by introducing a three-part taxonomy of false confessions that is universally accepted today. He also developed laboratory paradigms that are now used to examine why people are targeted for interrogation, why they waive their rights, why they confess, the corruptive effects of confessions on other evidence, the consequences of confessions in court, forensic confirmation biases, and the use of video recording to alleviate these problems. He has published numerous articles on the subject.
Dr. Kassin has received the American Psychological Association (APA) Award for Distinguished Contribution to Research in Public Policy (2017), the European Association of Psychology and Law (EAPL) – Award for Distinguished Lifetime Contribution (2017), the American Psychology-Law Society (AP-LS)-Award for Distinguished Lifetime Contribution (2014), and the International Investigative Interviewing Research Group (iiiRG)-Lifetime Achievement Award (2011). His work is cited all over the world—including by the U.S. Supreme Court and the Supreme Court of Canada.
Past President of the American Psychology-Law Society (AP-LS), Dr. Kassin has served as a consultant in a number of high profile cases and has testified in state, federal, and military courts. He is senior author of the 2010 AP-LS White Paper, “Police-Induced Confessions: Risk Factors and Recommendations” -- which has served as a template for several APA amicus briefs to state supreme courts. He lectures frequently to psychologists, judges, lawyers, law enforcement groups, and state criminal justice commissions and task forces; and he has appeared as a media consultant and guest for all major news networks, the Oprah Winfrey Show, National Public Radio, and in a number of podcasts and documentaries--including Ken and Sarah Burns' 2012 film, The Central Park Five.
