About this episode
Justin Sunseri discusses the criticisms of the Polyvagal Theory and evaluates the claims made by critics.
A paper co-authored by 39 scientists called the Polyvagal Theory "untenable" — and now psychology influencers are announcing the Theory is "dead." But is it?

In this episode, I break down Paul Grossman's paper "Why the Polyvagal Theory Is Untenable." We need to objectively check whether his criticisms accurately represent what the theory actually says. Because if they don't, the counterarguments are moot.
