Is there any research to back up hypnosis?

And actually, the research at in hypnosis backs this all up. There’s all kinds of research trying to get people to do things which are an ethical violation – a violation of their own moral code. And the result is, it simply does not work.

As an example, Milton Erickson – the famous hypnotherapist – was working with one lady who he knew had an issue with another lady in the workplace. This was a hospital. So he knew that she really disliked another of the nurses. So in
trance, he tried to implant the suggestion that when the trance was over she was going to get up, walk out of the room, find this other nurse, and, in a state of trance, slap this other nurse across the face.
