CBT vs EMDR
A side-by-side comparison: mechanism, evidence, the conditions each treats, philosophical roots, and where they actually disagree clinically.
At a glance
How they work
CBT
Core mechanism: Identifying and restructuring cognitive distortions + behavioral experiments + exposure reduces maladaptive appraisals and avoidance
Ontology: Dysfunctional cognitions (automatic thoughts, core beliefs) that distort appraisal of self, world, and future
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

What each assumes — and misses
CBT
Philosophical roots: Epictetus, Marcus Aurelius (Stoic appraisal theory — it is not things that disturb us but our judgments); Kant (rational autonomy); Popper (falsifiability as therapeutic method); Ellis cited Stoics explicitly
Blind spots: May underemphasize attachment history, relational dynamics, and the therapeutic relationship itself as mechanism of change
Therapeutic voice: What evidence do you have for the thought that nobody cares about you?
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.
Choosing between them
CBT (Cognitive-Behavioral) and EMDR (Trauma-Focused) 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.
