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
Motivational Interviewing
Core mechanism: Resolving ambivalence through evocation of client's own change talk; autonomy support increases intrinsic motivation
Ontology: Ambivalence about change is normal; confrontation increases resistance, empathy reduces it

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?
Motivational Interviewing
Philosophical roots: Rogers (empathy, autonomy); Kierkegaard (stages, either/or); Festinger (cognitive dissonance); Deci & Ryan (self-determination theory)
Blind spots: Not a standalone treatment for most conditions; may feel insufficient when clients need more than ambivalence resolution
Therapeutic voice: On one hand you want to stop, and on the other hand it's serving an important function. What would you lose if you quit?
Choosing between them
CBT (Cognitive-Behavioral) and Motivational Interviewing (Humanistic) 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.
