Self-fulfilling prophecy and hypnotic response are not the same thing.

The authors used the "bogus-item" methodology originally used by C. Wickless and I. Kirsch (1989) to examine the effects of response expectancy manipulations on subjects' subsequently measured hypnotizability scores. The results of the first experiment failed to replicate Wickless and Kirsch's (1989) findings that surreptitious confirmation of suggested items (the bogus-item manipulation) leads to higher scores on subsequently measured hypnotic responsiveness. The second experiment tested if, in fact, response expectancies were enhanced by the bogus-item manipulation, and the manipulation's effect on behavioral and subjective responsiveness to hypnosis was reexamined. A significant increase was found in response expectancies as a result of the bogus item expectancy manipulation, but again no evidence that this manipulation led to increased hypnotic responsiveness was found. Hypnotic responsiveness may not be as reactive to expectancy manipulations as previously claimed, and it is suggested that the notion of hypnotic responsiveness as a trait-like ability is viable.
