Episode notes

If you tell someone that they're drinking a 620 calorie milkshake, but they're actually drinking a 380 calorie milkshakes, they will experience a decline in ghrelin. Most of us are not at all conscious about most of the things that are going on in our body. And I think that's what we're talking about this kind of subconscious classical conditioning. Your body is conditioned over the course again of 20, 30, 40, 50, 60 years of your own behavior to know what it needs to do to keep you fit.

How powerful is the placebo effect? After a good night’s sleep could a scientist convince you that you had tossed and turned, and if so, how would that affect your perceptions and behavior? What if a doctor told you that you had slept like a baby when in reality you had barely slept at all? Would hearing those words improve your performance on a difficult test?

In this episode we learn the answers to these questions and more as we explore how research continues to unravel the mysteries behind the placebo effect and how it can drastically alter our bodies and minds.

Our guest is Kristi Erdal, a psychologist at Colorado College who discovered placebo sleep along with one of her students, Christina Draganich. Draganich wondered if such a thing might exist after reading all the literature on placebos, and Erdal helped her create the research methods she used to test her hypothesis.
