The study was to determine
if eye movements had no correlation with sensory-based mental access, a null hypothesis. Nothing about hypnosis in the study.
hypnosis does not appear to aid with accurate recall of hidden memories
You are mostly right about that IMO since our natural urge is to comply, after failing to provide or know something, an answer is given without being factual - I learned that from a police investigator hypnotist.
So what you describe about changing people's minds definitely isn't outside the realm of what we know about hypnosis. Finding a p<.00001 is quite impressive; how did your study fare in the peer review process?
My doctoral committee didn't say very much, not even sure they really understood how the result could be useful, just complying with requirements and my doctoral committee's demands for quality. The ability to "change history" is a chilling technique that involves learning a person's mental process on validating something - "knowing something". If I ask you "how do you know things" you will probably respond that you don't know the mental processes involved, but if you understand what that person is doing mentally by knowing what their eye-movement is telling you, you might learn that they "picture it" then get a "feeling" followed by another visual test or it"sounds right" or something leading to some sensual satisfaction. I once saw a video of someone asking another person in a group "how do you know you know" and her eye movements were quite clear as he asked her multiple times - each showing the same sequence. It wasn't an NLP video, as the questioner did not determine anything by her eyes, he was just trying to find out the process she used while not recognizing her answers if he had known what to look for!
This personal method we all create for ourselves in our life-experiences can be observed, recorded, and used to gain trust, being led to understand things as being true because they are presented in forms and sequences that match our particular "belief" strategy. If done properly the client will "remember" things that never happened and/or disbelieve something now that they believed before - scary stuff indeed. I became pretty good at it in removing some "bad" memories, as I said, the power scared me and I tried using other methodologies, but found them less exciting and slower so I had to change vocations.
The more I did it the better I got, and then I realized that a lot of people had learned how to do that subconsciously while most therapists that I knew did not know this themselves and my thoughts of the whole profession faded. I just use it a little bit now out of habit after thirty-five years.
Note about the statistical outcome, that is why I left the bad data in my study, If I corrected the direction calls of my assistant on that one subject or eliminated that subject, my p. score would have been unbelievable, near p.<.000001
