...We agree with Lynn and psychologist Irving Kirsch of the University of Hull in England, who wrote in 1995 that “having failed to find reliable markers of trance after 50 years of careful research, most researchers have concluded that this hypothesis [that hypnosis is a unique state of consciousness] has outlived its usefulness.” Increasingly, evidence is suggesting that the effects of hypnosis result largely from people’s expectations about what hypnosis entails rather than from the hypnotic state itself. Still, it is always possible that future studies could overturn or at least qualify this conclusion. In particular, research on potential physiological markers of hypnosis may elucidate how hypnosis differs from other states of consciousness. Although hypnosis poses fascinating mysteries that will keep scientists busy for decades, it seems clear that it has far more in common with everyday wakefulness than with the watch-induced trance of Hollywood crime thrillers.
