We all have an image of what a hypnotist does. He says, “look into my eyes” while holding a gold pocket watch, pushing his subject into a semi-sleep, almost zombie-like state. Now the subject will obey everything the hypnotist tells him to do, however evil this may be. This has little basis in reality, but the question of what is going on when we are being hypnotised is, nevertheless, a fascinating one.
The Merriam Webster defines hypnosis as “a trancelike state that resembles sleep but is induced by a person whose suggestions are readily accepted by the subject”. Hypnos is the Greek God of sleep and there are many words which have this suffix hypnobate (sleepwalker), hypnagogic (bringing on sleep) and hypnotherapy (treatment of disease by hypnosis).
Can everyone be hypnotised? What the scientific consensus seems to be is that everyone is on a spectrum. Roughly 15% of the population are said to be highly hypnotizable. On the other hand, around 25% are thought to be not hypnotizable at all. As well as entertainers there are many applications. New Age therapists, Past Life therapists and Repressed Memory therapists all make use of hypnosis for their dubious ends.
Hypnosis has been the subject of debate for more than 200 years. Here we have to mention Dr. Franz Mesmer, the father of modern hypnotism, who believed that hypnosis was a mystical force flowing from the hypnotist into the subject; he called it “animal magnetism”. Hypnosis was originally known as mesmerism, after Mesmer, and we still use its derivative, mesmerize, today. As Mesmer turned out to be a fraud, the term hypnotism became the one which was most used.
We see what a person does under hypnosis, but it isn’t clear why he or she does it. This uncertainty is a result of the fact that consciousness and how the human mind works is still in many ways a mystery. And as I don’t see scientists arriving at a definitive explanation of the mind in the foreseeable future, hypnosis will probably not give all its secrets.
The person being hypnotised is generally very absorbed, relaxed, suggestible and in a state of expectation. The subconscious mind comes to the fore. Your inhibitions are reduced. Some studies say that changes do take place in the brain. However, that’s pretty unremarkable as brain functioning also changes when we relaxed, exhausted or highly attentive. Sceptics tend to argue that hypnotic subjects aren’t really in an altered state of consciousness. Social pressure and the influence of the hypnotist are often enough to convince people that they should act a certain way. When they find themselves obeying they erroneously conclude that they must be in a hypnotic trance. The power of belief is enough to cause remarkable changes in a person. If you think someone is compelling you to act a certain way, then that is how you will act. It may well be what is going in hypnotherapy. By thinking that hypnosis will ease your pain your mind will bring about this feeling. , It is very much like the placebo effect. Hypnosis and the placebo effect have a lot in common; both rely on the effects of suggestion and belief. Consequently it is really difficult to have an effective placebo control in a study of the effects of hypnosis. I should point out that not everyone agrees with the fakery hypothesis. I just haven’t seen alternative evidence that convinces me yet. It may be forthcoming in the future
The popular stereotypes of what hypnosis is that I referred to in my introduction bear little resemblance to actual hypnotism. In fact, our modern understanding of hypnosis clearly debunks these ideas. Subjects in a hypnotic state are not slaves to their “masters” – they have absolute free will. And they’re not actually in a semi-sleep state -they’re hyperattentive. In no way can hypnotized people be described mindless automatons. People are more suggestible and some inhibitions are reduced. But our safety and morality do not fly out of the window. People won’t do things during or after hypnosis that are out of character. Only in Hollywood can hypnosis turn a mild-mannered person into a cold-blooded murderer.
