However, psychologists have found that some people are more suggestible than others - i.e. they act on others' suggestions more of the time than other people. This has resulted in this being seen as a spectrum of suggestibility.
This has ramifications in the scientific research of hypnosis. People who are more easily put in to a state of hypnosis are also more suggestible. This means that they may not actually be entering a different psychological state, but rather just acting on social pressure. It is easier for them to comply than to disobey.
