Gary Greenberg on the Placebo Effect

Author and psychotherapist Gary Greenberg talks with EconTalk host Russ Roberts about the placebo effect. Is it real? How does the placebo effect influence drug testing? If it's real, what is the underlying mechanism of why it works and how might it be harnessed to improve health care? The conversation concludes with a discussion of how knowledge of the placebo effect has influenced Greenberg's psychotherapy practice.
