Irving Kirsch, Ph.D., is a lecturer at Harvard Medical School and Beth Israel Deaconness Medical Center in Boston. He is also Emeritus Professor of Psychology at the University of Hull in the U.K.
Dr. Kirsch is a noted expert on the placebo effect, and the originator of response expectancy theory, one of the main theoretical frameworks for understanding the placebo effect.
In recent years, Kirsch has turned his attention to the question of the efficacy of psychoactive medications, in particular antidepressants. In his latest book, The Emperor’s New Drugs: Exploding the Antidepressant Myth (Basic Books, 2010), he argues that there is no good evidence that antidepressants are more effective at relieving the symptoms of clinical depression than active placebos. (An “active placebo” is one that has detectable side effects, like dry mouth or nausea, but no therapeutic physiological activity.)
