Polyvagal Theory

Porges proposed that your nervous system constantly scans for cues of safety and danger below conscious awareness, a process he called neuroception. Depending on what it reads, you drop into one of a few states: calm and socially open when you feel safe, mobilized for fight or flight when you sense threat, or collapsed and shut down when threat feels inescapable.

For people-pleasing, the model offers a way to picture fawning as a nervous-system state rather than a choice. When the body reads someone's displeasure as danger, it can reach for appeasing as the path back to safety. You are not deciding to please. A protective state is running.

Polyvagal theory is an influential framework, not settled fact, and parts of it are debated among researchers. It is useful as a lens for what survival can feel like in the body, held as a model rather than proof.
