How they work
EMDR
Core mechanism: Bilateral stimulation during trauma memory processing facilitates adaptive information processing and memory reconsolidation (proposed)
Ontology: Unprocessed trauma memories stored dysfunctionally with original affect, sensation, and cognition
MDMA-Assisted Therapy
Core mechanism: MDMA reduces fear response and increases trust/empathy, enabling deeper trauma processing within therapeutic relationship
Ontology: PTSD maintained by overwhelming fear that prevents therapeutic engagement; MDMA lowers this barrier pharmacologically

What each assumes — and misses
EMDR
Philosophical roots: Merleau-Ponty (body holds memory); Bion (processing/containment); Pavlov (orienting response); Shapiro (adaptive information processing — pragmatic, not philosophically derived)
Blind spots: Mechanism debate unresolved; protocol fidelity varies; may be applied to conditions beyond its evidence base
Therapeutic voice: Bring up the image and the negative belief. Notice what you feel in your body. Now follow my fingers.
MDMA-Assisted Therapy
Philosophical roots: Mithoefer (inner healing intelligence); Rogers (organismic wisdom, given conditions); Buber (I-Thou enabled pharmacologically); trauma processing theory
Blind spots: FDA declined approval (2024); methodological concerns about unblinding; not currently legally available outside research
Therapeutic voice: You're safe here. If something difficult comes up, you can move toward it — you don't have to do this alone.
Choosing between them
EMDR (Trauma-Focused) and MDMA-Assisted Therapy (Psychedelic) come from different traditions, which means they assume different things about what a person is, what causes suffering, and what the therapeutic relationship is for. The choice between them is often less about "which works better" and more about which set of assumptions fits the client and the therapist.
