SIO510: Digging Into the Science of the Placebo Effect

Popular media will tell you that placebos, inert inactive substances taken as if they’re medication, can work miracles. …Placebos don’t “work”. But what does that even mean? And if that’s true, why would we include a placebo group in a study? Is there anything remotely like a “true”’placebo effect, where belief in a medication could influence the body? Jenessa walks us through scientific study design, statistical artifacts, and one study that shows maybe just maybe there’s a little something like an actual placebo “effect”… but it’s still not magic! Tune in to hear how on earth that could be possible. Nolan, T.A., Price, D.D., Caudle, R., Murphy, N.P., & Neubert, J.K. (2012). Placebo-induced analgesia in an operant pain model in rats.
