Following the French committee's findings, Dugald Stewart, an influential academic philosopher of the "Scottish School of Common Sense", encouraged physicians in his Elements of the Philosophy of the Human Mind (1818) to salvage elements of Mesmerism by replacing the supernatural theory of "animal magnetism" with a new interpretation based upon "common sense" laws of physiology and psychology. Braid quotes the following passage from Stewart:
"I feel now I am ready to express an experience that has transformed my life and in the process the lives of lots of people! To begin with, I could not have imagined that I would no longer feel my (formerly) chronic backache. I have learned to relax the muscles and actually pass on the healing thoughts and energy to the pain areas. The changes in my life are nothing short of a miracle. Healing my personal relationships has been the highlight....
We know it is hard to sort out all the different claims made by some so-called “hypnosis schools and boards.” Stay away from “distance learning” or correspondence courses that claim to certify you as a clinical hypnotherapist. Hypnosis and hypnotherapy is a healing art based on scientific methods. Only basic hypnotherapy theory can be obtained from the right books or videos. Effectiveness is unlikely without live demonstrations, in-depth and advanced discussion, question and answer opportunities and supervised clinical practice. Just as correspondence courses are inappropriate for counselors, medical doctors and massage therapists, they are wrong for people who want to be effective and successful clinical hypnotherapists.
In 1996, as a result of a three-year research project led by Lindsay B. Yeates, the Australian Hypnotherapists Association (founded in 1949), the oldest hypnotism-oriented professional organization in Australia, instituted a peer-group accreditation system for full-time Australian professional hypnotherapists, the first of its kind in the world, which "accredit[ed] specific individuals on the basis of their actual demonstrated knowledge and clinical performance; instead of approving particular 'courses' or approving particular 'teaching institutions'" (Yeates, 1996, p.iv; 1999, p.xiv). The system was further revised in 1999.
People have been pondering and arguing over hypnosis for more than 200 years, but science has yet to fully explain how it actually happens. We see what a person does under hypnosis, but it isn't clear why he or she does it. This puzzle is really a small piece in a much bigger puzzle: how the human mind works. It's unlikely that scientists will arrive at a definitive explanation of the mind in the foreseeable future, so it's a good bet hypnosis will remain something of a mystery as well.
In Trance on Trial, a 1989 text directed at the legal profession, legal scholar Alan W. Scheflin and psychologist Jerrold Lee Shapiro observed that the "deeper" the hypnotism, the more likely a particular characteristic is to appear, and the greater extent to which it is manifested. Scheflin and Shapiro identified 20 separate characteristics that hypnotized subjects might display: "dissociation"; "detachment"; "suggestibility", "ideosensory activity"; "catalepsy"; "ideomotor responsiveness"; "age regression"; "revivification"; "hypermnesia"; "[automatic or suggested] amnesia"; "posthypnotic responses"; "hypnotic analgesia and anesthesia"; "glove anesthesia"; "somnambulism"; "automatic writing"; "time distortion"; "release of inhibitions"; "change in capacity for volitional activity"; "trance logic"; and "effortless imagination".
Charcot operated a clinic at the Pitié-Salpêtrière Hospital (thus, known as the "Paris School" or the "Salpêtrière School"), while Bernheim had a clinic in Nancy (known as the "Nancy School"). Charcot, who was influenced more by the Mesmerists, argued that hypnotism was an abnormal state of nervous functioning found only in certain hysterical women. He claimed that it manifested in a series of physical reactions that could be divided into distinct stages. Bernheim argued that anyone could be hypnotised, that it was an extension of normal psychological functioning, and that its effects were due to suggestion. After decades of debate, Bernheim's view dominated. Charcot's theory is now just a historical curiosity.
In 1974, Theodore X. Barber and his colleagues published a review of the research which argued, following the earlier social psychology of Theodore R. Sarbin, that hypnotism was better understood not as a "special state" but as the result of normal psychological variables, such as active imagination, expectation, appropriate attitudes, and motivation. Barber introduced the term "cognitive-behavioral" to describe the nonstate theory of hypnotism, and discussed its application to behavior therapy.
There are numerous applications for hypnosis across multiple fields of interest, including medical/psychotherapeutic uses, military uses, self-improvement, and entertainment. The American Medical Association currently has no official stance on the medical use of hypnosis. However, a study published in 1958 by the Council on Mental Health of the American Medical Association documented the efficacy of hypnosis in clinical settings.
In 2013, the then-40-year-old amateur hypnotist Timothy Porter attempted to sexually abuse his female weight-loss client. She reported awaking from a trance and finding him behind her with his pants down, telling her to touch herself. He was subsequently called to court and included on the sex offender list. In 2015, Gary Naraido, then 52, was sentenced to 10 years in prison for several hypnosis-related sexual abuse charges. Besides the primary charge by a 22-year-old woman who he sexually abused in a hotel under the guise of a free therapy session, he also admitted to having sexually assaulted a 14-year-old girl.
The Federal Dictionary of Occupational Titles describes the job of the hypnotherapist: "Induces hypnotic state in client to increase motivation or alter behavior patterns: Consults with client to determine nature of problem. Prepares client to enter hypnotic state by explaining how hypnosis works and what client will experience. Tests subject to determine degree of physical and emotional suggestibility. Induces hypnotic state in client, using individualized methods and techniques of hypnosis based on interpretation of test results and analysis of client's problem. May train client in self-hypnosis conditioning. GOE: 10.02.02 STRENGTH: S GED: R4 M3 L4 SVP: 7 DLU: 77"
