A person is deemed to be suggestible if they accept and act on suggestions by others. Obviously, everyone acts at some point in their lives by the suggestions given by someone else.

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.
