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 (9th 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.
Dr. Kassin is interested in 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 that is universally accepted today. He also developed laboratory paradigms that are widely 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, and the use of video recording to alleviate these problems. He has published numerous scientific articles and book chapters on the subject and was awarded an APA presidential citation for his research on false confessions. His work is cited all over the world—including by the U.S. Supreme Court in Salinas v. Texas (2013). For research on the video recording of interrogations, he is currently funded by the National Science Foundation.
Dr. Kassin is Past President of the American Psychology-Law Society (AP-LS) He has served as a consultant in a number of high profile cases and has testified in several state, federal, and military courts. He is senior author of the 2010 AP-LS White Paper entitled “Police-Induced Confessions: Risk Factors and Recommendations.” 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 and in a number of documentaries--including Ken Burns' 2012 film, The Central Park Five.
