Practically-A-Book Review: Byrnes on Trance

A 'practically a book review' of Steven Byrnes's predictive-processing series on intuitive self-models. Premise: we perceive our brain's MODELS, not reality (checker-shadow, blind spot, and bistable images like the spinning dancer, which flip viscerally when the underlying guess changes). Byrnes extends this to the inner world: the felt 'self' is a 'homunculus' model of mental processes, and 'homunculus' vs 'trance/possession' are two bistable models of one's own mind. Trance is induced by a four-step flip (seed a plausible alternative model, relax, suppress old-model evidence via stillness, gather new-model evidence -- the stage-hypnosis arm-raise/jump sequence, Johnstone's rig-the-ESP-cups trick). The framework then explains dissociative amnesia, multiple personality (borderline 'splitting' + a therapist's priming), ketamine ego death (the homunculus model breaks when thoughts stop cohering), Buddhist satori (a bistable flip -- elegantly explaining why enlightenment is reported as instantaneous), and Jaynes's bicameral mind (a whole civilization running the possession model).

Quality 76 · Excellent. Excellent floor. A lucid synthesis that makes a genuinely hard cluster (trance, hypnosis, dissociation, ego death, enlightenment) legible under one elegant idea, with the satori-as-bistable-flip the standout payoff. Held at the floor (and just under the kindred IFS review) because the framework is Byrnes's and Scott is expositing it.

Claude’s paradigm shift 54 · Moderate. Moderate. The predictive-processing self-model framework is Byrnes's; Scott's contribution is the clear exposition and the connective insights (satori as a perceptual flip).

Real-world impact 2 · Minor. Minor. Circulates within the rationalist / neuroscience-of-mind discourse; no material reach. Within-niche.
