Suggestibility.

Hypnosis is very much based on 'suggestibility'. Suggestibility is nothing special. It is just a condition where a person readily accepts suggestions without any inhibition. Every person is suggestible at various extents. There is one more term called 'gullibility'. Gullibility also forms the base of hypnosis. In fact it is next stage of suggestibility. Suggestion is never in demanding nature. It could be authoritative. Gullibility can be simply be explained as accepting suggestions blindly. Gullibility is seen especially in children. It's like when I say to small child that there is scary ghost in dark. He will blindly follow it. He'll not only assume but will affirm that darkness is very scary. This is because of lack of reasoning. When you think about an action before actually doing it, you will try do it perfectly. When you do it without thinking, you have no option of performing it perfectly. I can make it simpler. I might say about an incidence which you might have experienced in your life or at least you must have witnessed. When a person is struck with electric shock the first thing he does is that he tries to get rid of it. This is called fight and flight mechanism, where an individual does not think about the response. It works by itself. It can also be called as a Reflex action. So the point is, it is not a planned action, but it saves one's life.

So suggestibility is a tool to create a hypnotic effect on people. Almost 95% of the human beings can be hypnotized easily.

Moral of the story is that suggestibility transforms into gullibility with the help of hypnosis.
