Dr. Jordan Peterson, just one of four speakers from the "Mind Matters: Toward a New Understanding of Psychopathology" conference, held on Saturday March 19, 2011, gives a talk on "Self-Deception in Psychopathology." Information about the conference: What does it mean for the mind to be pathological? What criterion should we use to diagnose and categorize people as mentally ill? Can there be alternative models of psychopathology other than the medical model? If so, what are they?
