How they work
NARM
Core mechanism: Simultaneously tracking somatic experience, relational patterns, and identity-level beliefs reveals how developmental survival styles organized around early unmet needs are maintained in the present
Ontology: Early attachment failures create survival styles that organize identity, relationships, and somatic patterns into predictable configurations; the self-structure formed around deprivation, not the original events, is what maintains suffering
Somatic Experiencing
Core mechanism: Titrated pendulation between activation and resource states completes truncated survival responses trapped in the body
Ontology: Incomplete defensive responses (fight/flight/freeze) remain bound in the nervous system as undischarged survival energy

What each assumes — and misses
NARM
Philosophical roots: Heller (developmental trauma and identity); Reich (character armor — reimagined developmentally); Bowlby (attachment); Schore (affect regulation); Winnicott (true self/false self); Lowen (bioenergetics, reframed)
Blind spots: Limited empirical evidence; five survival styles risk becoming rigid typology; developmental focus may not address acute symptom presentations; less helpful for single-incident trauma
Therapeutic voice: You're telling me about this pattern of always taking care of others. As you say that, what do you notice happening in your body? And I'm curious — what happens inside when you imagine someone wanting to take care of you?
Somatic Experiencing
Philosophical roots: Reich/Lowen (body holds defense — Levine studied with both); Merleau-Ponty (lived body); Darwin (survival instincts); ethology (Tinbergen, Lorenz — animal defensive responses); James-Lange (emotion as bodily process)
Blind spots: Risk of over-physiologizing psychological meaning; limited manualization makes research difficult; can be vague in application
Therapeutic voice: Where in your body do you feel that right now? Just notice, without trying to change it.
Choosing between them
NARM and Somatic Experiencing both sit within the Somatic tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
