The Polyvagal Theory (2011)

What they contributed

Porges developed polyvagal theory, which maps the autonomic nervous system's three-tiered hierarchy: the ventral vagal (safety, social engagement), the sympathetic (mobilization, fight/flight), and the dorsal vagal (immobilization, freeze, shutdown). His work explains how the body's threat-detection system operates below conscious awareness and how safety — genuinely felt in the nervous system, not just cognitively assessed — is the prerequisite for healing, learning, and authentic relationship.

Why it matters here

Polyvagal theory is the physiological substrate beneath every article on why healing requires more than insight. It explains why people freeze before charging more, why love can feel like danger, and why nervous system regulation is the foundation of behavioral change.
