Is Polyvagal Theory Evidence-Based?

If you work with the nervous system, you've almost certainly encountered Polyvagal Theory, and you've likely noticed the controversy that surrounds it.

Published researchers in comparative neuroscience and physiology have raised serious questions about its scientific foundations - questions that deserve a proper answer, not a 90-second reel stripped of context, depth, and nuance.

So Where Does the Evidence Stand?

After reviewing 50+ peer-reviewed sources, I can tell you the answer is more nuanced than the headlines suggest.

Right now, you're either hearing that Polyvagal Theory is settled science or that it's been debunked. Neither is accurate. And as practitioners we deserve better than that.

We deserve a clear, honest read of the evidence so we can work with integrity and confidence.

This workshop is designed for coaches, clinicians, therapists, psychologists, educators, and health professionals who draw on Polyvagal Theory in their work and want to know exactly where the science stands.

What you'll walk away with:

1. An evidence scorecard that clearly separates what's well-supported, what's partially supported, and what's actively contested, so you can immediately audit your own language and teaching.

2. A grounded understanding of what is well-established about the nervous system, independent of the Polyvagal debate. This is the foundation your practice can stand on.

3. Practical guidance you can use straight away: what to keep saying, what to stop saying, and how to talk about nervous system regulation with credibility and clinical accuracy.

4. Complementary evidence-based frameworks that strengthen your clinical reasoning and make your work more robust.

You'll leave with clarity on the research and practical frameworks ready to take into your next session.

I'd love to see you there.

Warmly,

Jessica
