Illusionists, such as Joseph Rinn have staged 'fake' séances in which the sitters have claimed to have observed genuine supernatural phenomena. Albert Moll studied the psychology of séance sitters. According to (Wolffram, 2012) "[Moll] argued that the hypnotic atmosphere of the darkened séance room and the suggestive effect of the experimenters' social and scientific prestige could be used to explain why seemingly rational people vouchsafed occult phenomena." The psychologists Leonard Zusne and Warren Jones in their book Anomalistic Psychology: A Study of Magical Thinking (1989) wrote that spirits controls are the "products of the medium's own psychological dynamics."
Being a half-ass psychic, I wondered whether he meant business partner or sex partner. He soon revealed she was both—and they were starting a company together. My intuition/magical powers told me this woman was about to leave him high and dry, but common sense told me that news might offend him and blow my chances of landing this job. Fortunetelling has no solid ethics, so I told him what I believed he wanted to hear. And I got the job.
After Valentine's Day, it only got stranger. Callers asked about lost jewelry and I'd instead tell them about their children or partners, which only pissed them off. HR called and told me to stop doing that—if someone wanted "remote viewing," I was to tell him or her to call a psychic who had that skill listed on their profile. I was, and still am, impressed by how seriously my employer treated "real psychic powers" instead of just racking up minutes. But I also noticed that bad reviews never made it to my profile or anyone else's, which sickened me.
The psychical researchers Eric Dingwall and Harry Price re-published an anonymous work written by a former medium entitled Revelations of a Spirit Medium (1922) which exposed the tricks of mediumship and the fraudulent methods of producing "spirit hands". Originally all the copies of the book were bought up by spiritualists and deliberately destroyed. In 1923, the magician Carlos María de Heredia revealed how fake spirit hands could be made by using a rubber glove, paraffin and a jar of cold water.
In 1960, psychic investigator Andrija Puharich and Tom O'Neill, publisher of the Spiritualist magazine Psychic Observer, arranged to film two seances at Camp Chesterfield, Indiana using infrared film, intending to procure scientific proof of spirit materializations. The medium was shown the camera beforehand, and was aware that she was being filmed. However, the film revealed obvious fraud on the part of the medium and her cabinet assistant. The exposé was published in the 10 July 1960 issue of the Psychic Observer.:96–97
According to the magician John Booth the stage mentalist David Devant managed to fool a number of people into believing he had genuine psychic ability who did not realize that his feats were magic tricks. At St. George's Hall, London he performed a fake "clairvoyant" act where he would read a message sealed inside an envelope. The spiritualist Oliver Lodge who was present in the audience was duped by the trick and claimed that Devant had used psychic powers. In 1936 Devant in his book Secrets of My Magic revealed the trick method he had used.
Most telephone psychic clients are repeat customers, who rely on their telephone psychic to provide accurate and timely advice that is pertinent to their lives. It is all done over the phone.
