How they work
Behavioral Activation
Core mechanism: Increasing contact with positive reinforcement through scheduled activities reverses withdrawal-depression cycle
Ontology: Depression maintained by behavioral withdrawal and loss of positive reinforcement
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

What each assumes — and misses
Behavioral Activation
Philosophical roots: Skinner (behavior as function of consequences); Lewinsohn (behavioral model of depression); pragmatism (act first, meaning follows)
Blind spots: Addresses behavioral withdrawal but not underlying meaning-making, relational patterns, or trauma
Therapeutic voice: I notice you've stopped doing everything that used to bring you satisfaction. What's one small thing we could put back?
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?
Choosing between them
Behavioral Activation and CBT 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.
