In 1930 the Polish medium Stanisława P. was tested at the Institut Metapsychique in Paris. French psychical researcher Eugéne Osty suspected in the séance that Stanislawa had freed her hand from control. Secret flashlight photographs that were taken revealed that her hand was free and she had moved objects on the séance table. It was claimed by spiritualists that during a series of séances in 1930 the medium Eileen J. Garrett channeled secret information from the spirit of the Lieutenant Herbert Carmichael Irwin who had died in the R101 crash a few days before the séance. Researcher Melvin Harris who studied the case wrote that the information described in Garrett's séances were "either commonplace, easily absorbed bits and pieces, or plain gobblede-gook. The so-called secret information just doesn't exist."
Modern tarot decks, such as we know them, appeared in Italy in the 15th century as series of intricately painted works of art used to play card games. These decks consisted of a varying number of cards and were not specifically created for divination. The first such cards, usually created for noble families to celebrate special occasions, were known in Italy as trionfi (“triumphs” or later, “trumps.”) These trick-taking games later became known by several names, including Tarocchi, Taroc/k, Tarau,and Tarot. Some people even write it as tarrot, taro or tarro - but those spellings are very uncommon.
In 1876, William Eglinton was exposed as a fraud when the psychical researcher Thomas Colley seized a "spirit" materialization in his séance and cut off a portion of its cloak. It was discovered that the cut piece matched a cloth found in Eglinton's suitcase. Colley also pulled the beard off the materialization and it was revealed to be a fake, the same as another one found in the suitcase of Eglinton. In 1880 in a séance a spirit named "Yohlande" materialized, a sitter grabbed it and was revealed to be the medium Mme. d'Esperance herself.
No doubt a great importance in the paranormal field is the problem of fraud. The field of psychic research and spiritualism has been so notoriously full of charlatans, such as the Fox sisters and Eusapia Palladino–individuals who claim to have special power and gifts but who are actually conjurers who have hoodwinked scientists and the public as well–that we have to be especially cautious about claims made on their behalf.
At the same time, if the psychic medium says that Frances is here, and your mother’s name is Francine, don’t say you have no idea what they are talking about. Or if the psychic medium says that your father is wearing a police uniform but your father wore a security uniform, remember that you don’t have to be a psychic medium to mix that one up—anyone could make that mistake. Keep in mind that the clarity of communication may be more like an AM radio station than a telephone. Small inaccuracies are expected. Don’t hold the psychic medium to exact measurements.
Because the spirits who respond to the channelers are satanic, channeling is abhorrent to God. There are few who have any true conception of the deceptive power of spiritualism and the danger of coming under its influence. Many tamper with it merely to gratify their curiosity. They have no real faith in it and would be filled with horror at the thought of yielding themselves to the spirits' control. But they venture upon the forbidden ground, and the mighty destroyer exercises his power upon them against their will. Let them once be induced to submit their minds to his direction, and he holds them captive. It is impossible, in their own strength, to break away from the bewitching, alluring spell. Nothing but the power of God, granted in answer to the earnest prayer of faith, can deliver these ensnared souls.
But here's the interesting part: the writing samples produced were analyzed and it was found that the complexity scores for the psychographed content were higher than those for the control writing across the board. In particular, the more experienced mediums showed higher complexity scores, which typically would require more activity in the frontal and temporal lobes--but that's precisely the opposite of what was observed.
Today "demonstration of mediumship" is part of the church service at all churches affiliated with the National Spiritualist Association of Churches (NSAC) and the Spiritualists' National Union (SNU). Demonstration links to NSAC's Declaration of Principal #9. "We affirm that the precepts of Prophecy and Healing are Divine attributes proven through Mediumship."
Often, I will do a Skype call with my best friend in the evening, when she is off work. She lays the cards out for me on her Turkish scarves then - ta-da! - the fortune-telling happens. Because she knows me so well, since we were pip-squeaks, it is helpful to have her insight on what each card forebodes. After the reading, I get to process it all with my pal then take it with me into my dreams.
