so much of your statement is based on misunderstanding or misconception that i am not going to waste time picking through it.
To refute the idea that hypnosis does not exist I will cite come references that are
reliable sources of information.
The British Psychological Society (BPS) (as opposed to Penn & Teller) present their view and findings of hypnosis here
BPS Statement on HypnosisThe national institute for clinical excellence have an extremely rigoursous process for validating research. the process of how treatments become recommended can be read here
NICE clinical guidelines development process.
NICE have recomended hypnosis as a treatment for IBS. The guidance can be read here
http://www.nice.org.uk/nicemedia/live/11927/39746/39746.pdf In the Genreal Glossary on p18 there is a brief description of hypnotherapy and its application for IBS. there are other references to hypnosis throughout this document.
In the treatment of obesity Cognitive Behvioural Therapy (CBT) combined with hypnosis has been shown to be more effective than CBT alone. See:
Anderson, M. S. (1985). Hypnotizability as a factor in the hypnotic treatment of obesity. Int. J. Clin. Exp. Hypn., 33, 150-159
Barabasz, M. & Spiegel, D. (1989). Hypnotizability and weight loss in obese subjects. Int. J. Clin. Eat. Dis., 8, 335-341
A number of long term studies have also shown that hypnotherapy alone is superior to cognitive behavioural therapy for treating obesity. See:
Cochrane, G. J. (1987) Hypnotherapy in weight-loss treatment: Case illustrations. Am. J. Clin. Hyp., 30, 20-27.
Bolokofsky, D. N. Spinkler, D & Coulthard-Morris, L. (1985). Effectiveness of Hypnosis as an adjunct to behavioural weight management. J. Clin Psychol., 41, 35-41.
Cochrane, G. J. and Friesen, J. (1986) Hypnotherapy in weight loss. J. Consult. Clin. Psychol.,
These are just a selection of the clinical applications of hypnosis and there are plenty more applications that have been researched and evidenced.
