461: Erik Vance | The Curious Science of the Suggestible You

Scientific Basis

Erik Vance explains how the placebo effect is deeply rooted in our brain's mechanisms and psychological factors. He highlights that our brain creates expectations based on past experiences, which can lead to powerful placebo responses. For instance, placebo injections are often more effective than pills due to the elaborate expectations they create 1.

The more expensive it is, the better your taste experience, things like that. So does that follow then, that let's say a pill placebo is maybe less effective than an injection?

--- Jordan Harbinger

This phenomenon is evident in various forms, such as sham surgeries being more effective than placebo pills, particularly in conditions like Parkinson's disease 2.

   

Real-World Applications

Placebos have significant real-world applications, especially in treating symptoms of chronic conditions. Erik Vance notes that while placebos can alleviate symptoms like pain and nausea, they are not effective against the underlying disease, such as tumors in cancer patients 3.

You have to trust but verify. Like there's, there's this line to walk because you can benefit from placebos.

--- Erik Vance

He emphasizes the importance of balancing placebo use with conventional medicine to avoid dangerous outcomes 4.

   

Examples

Specific examples and experiments illustrate the diverse effects of placebos. Erik Vance describes how the brain can release chemicals to mimic the effects of real drugs, creating a powerful placebo response 5.

Your brain then goes, "Okay, let's just drop out some opioids will feel better."

He also discusses how placebos are particularly effective in treating conditions like pain, anxiety, and irritable bowel syndrome, but less so for diseases like Alzheimer's 6.
