How they work
KAP
Core mechanism: Ketamine-induced neuroplasticity + dissociative state creates window for psychotherapeutic processing and new learning
Ontology: Treatment-resistant conditions involve rigid neural patterns; ketamine disrupts rigidity and opens plasticity window
Psilocybin-Assisted Therapy
Core mechanism: Psilocybin disrupts default mode network rigidity; mystical-type experiences occasion lasting shifts in perspective and meaning
Ontology: Rigid self-referential processing (depression) or compulsive patterns maintained by entrenched neural networks

What each assumes — and misses
KAP
Philosophical roots: James (varieties of religious experience — altered states as data); Grof (non-ordinary states); neuroplasticity research; mystical tradition broadly
Blind spots: Regulatory fragmentation; limited standardization of psychotherapy component; risk of ketamine becoming the treatment rather than catalyst
Therapeutic voice: As the medicine takes effect, just notice what arises without directing it. We'll make sense of it together.
Psilocybin-Assisted Therapy
Philosophical roots: James (mystical experience); Huxley (doors of perception, reducing valve theory); Watts (ego dissolution); Buddhist concepts (non-self, interconnection); Carhart-Harris (entropic brain hypothesis)
Blind spots: Not FDA approved; challenging experiences can be destabilizing; standardization of therapy component still developing
Therapeutic voice: Whatever comes, let it come. Whatever goes, let it go. Trust the process.
Choosing between them
KAP and Psilocybin-Assisted Therapy both sit within the Psychedelic 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.
