Abstract
Kirsch argues clinical hypnosis operates through response expectancy and nondeceptive placebo logic — participants know suggestions are symbolic yet still respond — rather than requiring a unique altered state.

Key findings
- Expectancy mechanism — Hypnotic response scales with what participants expect the intervention to do — not only with “depth of trance.”
- Nondeceptive placebo — Symbolic suggestions work when the frame is honest — relevant to Autohypnosis training loops.
Application
When self-hypnosis feels “fake” — tighten expectancy + repetition + cue before chasing deeper trance labels.
