Guests discuss current technology used for detecting lies, and a new device based on brain scans. It's potentially more effective than other means, but the device raises issues of accuracy, ethics, consent and privacy.

Guests:

Daniel Langleben, psychiatrist at the University of Pennsylvania; pioneer in the lie-detection field

Paul Wolpe, senior fellow at the University of Pennsylvania's Center for Bioethics
