How they work

ERP

Core mechanism: Prolonged exposure to obsessional triggers without compulsive response produces habituation and inhibitory learning

Ontology: Obsessions are maintained by compulsive neutralization; avoidance prevents disconfirmation

Metacognitive Therapy

Core mechanism: Modifying metacognitive beliefs about worry/rumination + detached mindfulness interrupts the Cognitive Attentional Syndrome

Ontology: Not the content of thoughts but metacognitive beliefs about thinking (worry is useful/uncontrollable) maintain disorder

What each assumes — and misses

ERP

Philosophical roots: Mowrer (two-factor theory); Pavlov (classical conditioning); Rachman (habituation); Craske (inhibitory learning); empiricism broadly

Blind spots: Highly effective for OCD but narrow in scope; exposure without relational attunement can feel mechanical

Therapeutic voice: I know touching the doorknob without washing feels unbearable right now. Can you stay with that feeling and let it be?

Metacognitive Therapy

Philosophical roots: Wells (metacognitive model); Flavell (metacognition research); distinct from Buddhist mindfulness despite surface similarity — targets beliefs about thinking, not present-moment awareness

Blind spots: Narrow focus on metacognitive beliefs may miss relational and developmental dimensions; relatively new evidence base

Therapeutic voice: You believe worrying keeps you safe. Let's test that: what if you postponed all worry to a 15-minute window?

Choosing between them

ERP and Metacognitive Therapy both sit within the Cognitive-Behavioral 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.
