Using Hypnosis as a Non-Deceptive Extra-Strength Placebo

Similarities between hypnosis and the placebo effect include

  1. Both affect the same clinical conditions.
  2. Expectancy manipulations can enhance both placebo and hypnotic responding.
  3. Neither requires the presence of a trance state.
  4. Like placebos, hypnotic inductions have no specific components.
  5. Suggestion is the active ingredient of both. 

Although this does not make hypnosis a placebo, it does indicate that that research on the placebo effect and the therapeutic relationship can inform optimal clinical use of hypnosis.
