In some ways, it sounds like a modern-day witch trial: using brain scans to detect a suspect’s first-hand recollection of an act they stand accused of committing. Some experts around the world have suggested that a test like this could hamper the efforts of those who attempt to lie their way out of trouble in court, hailing the technology as an advance potentially as important as DNA evidence. What are the legal ramifications of using this kind of technology in court, and if this test isn’t a panacea, is there another method in the forensic pipeline that could be? Host Dr. Mark Nolan Hill peers into the future of lie detection with Dr. J. Peter Rosenfeld, professor of psychology at Northwestern University, and Henry Greely, professor of law and director of the Center for Law and the Biosciences at Stanford University.
