How they work
IFS
Core mechanism: Self-energy (curiosity, compassion, calm) accesses and unburdenes exiled parts; protector parts relax when exiles are healed
Ontology: Internal system of parts carrying burdens from attachment injuries; protectors manage exiles' pain
Schema Therapy
Core mechanism: Limited reparenting + experiential techniques + cognitive restructuring heal early maladaptive schemas and shift maladaptive coping modes
Ontology: Early maladaptive schemas from unmet core emotional needs in childhood perpetuated by maladaptive coping

What each assumes — and misses
IFS
Philosophical roots: Systems theory (Bertalanffy); Schwartz (inner system as family); Jung (subpersonalities, Self); Buddhist concept of witnessing awareness (Self-energy); multiplicity of mind (Ornstein, Minsky)
Blind spots: Popularity far outpaces evidence base; parts language can become reified; limited research outside pilot studies
Therapeutic voice: Can you ask that critical part what it's afraid would happen if it stepped back?
Schema Therapy
Philosophical roots: Winnicott (true self/false self); Klein (internalized objects); Bowlby (attachment); Piaget (schema as organizing structure); object relations tradition broadly
Blind spots: Long treatment can be costly; limited reparenting may cross boundaries for some therapists; less evidence outside BPD
Therapeutic voice: That sounds like the Defectiveness schema talking. Can we hear from Healthy Adult instead?
Choosing between them
IFS (Family Systems) and Schema Therapy (Cognitive-Behavioral) 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.
