Saul is a Distinguished Professor of Psychology at John Jay College of Criminal Justice in New York and Massachusetts Professor Emeritus at Williams College, in Williamstown, MA.
He is author of Psychology (Prentice Hall, 4th edition) and Psychology in Modules (Pearson Custom Publishing). Along with Steven Fein and Hazel Markus, he is also lead author of Social Psychology (11th edition), published by Cengage Learning. He has published numerous research articles and book chapters, has co-authored or edited various scholarly books, and is the lead author on the Official APA White Paper on false confessions.
He has appeared as an analyst on CBS, NBC, ABC, CNN, and various syndicated news shows, and in several documentaries – most notably, the 2012 film, The Central Park Five. In the 1980s, he pioneered the scientific study of false confessions by introducing a taxonomy that distinguished between three types of false confessions (voluntary, compliant, and internalised) that is universally accepted today and by devising laboratory paradigms to test why innocent people are targeted for interrogation and why they confess.
Interested in matters of policy and reform, his recent research on the video recording of interrogations was funded by the National Science foundation.
