In 1970 two psychical researchers investigated the direct-voice medium Leslie Flint and found that all the "spirit" voices in his séance sounded exactly like himself and attributed his mediumship to "second-rate ventriloquism". The medium Arthur Ford died leaving specific instructions that all of his files should be burned. In 1971 after his death, psychical researchers discovered his files but instead of burning them they were examined and discovered to be filled with obituaries, newspaper articles and other information, which enabled Ford to research his séance sitters backgrounds.
An experiment conducted by the British Psychological Society in 2005 suggests that under the controlled condition of the experiment, people who claimed to be professional mediums do not demonstrate the mediumistic ability. In the experiment, mediums were assigned to work the participants chosen to be "sitters." The mediums claimed to contact the deceased who were related to the sitters. The research gather the numbers of the statements made and have the sitters rate the accuracy of the statements. The readings that were considered to be somewhat accurate by the sitters were very generalized, and the ones that were considered inaccurate were the ones that were very specific.
At Waite's suggestion, Smith used the Sola Busca artwork for inspiration, and there are many similarities in the symbolism between Sola Busca and Smith's final result. Smith was the first artist to use characters as representative images in the lower cards. Instead of showing merely a cluster of cups, coins, wands or swords, Smith incorporated human figures into the artwork, and the result is the iconic deck that every reader knows today.
Brenda’s exchanges with Spirit began as a child - a deceased grandfather who regularly visited the family, an accidental death that required a loved one to receive messages; these are emotional situations with which she has since become adept. She offers her mediumship with a level head and a comforting presence communicating with the deceased, explaining past life memories which are affecting current relationships or goals; she unfolds different, difficult, and crisis situations bringing clarity to the present and preparation for the future. Brenda is also retained by clients wishing her insights concerning financial security/business expansions, etc. and from Spirit she has related detailed assistance in the feilds of science and technology. Through her, Spirit often provides perspective that remove anxiety or clear guilt.
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."
The mediums ranged from 15 to 47 years of automatic writing experience, performing up to 18 psychographies per month. All were right-handed, in good mental health, and not currently using any psychiatric drugs. All reported that during the study they were able to reach their usual trance-like state during the psychography task and were in their regular state of consciousness during the control task.
"Have a little fun with friends," she told INSIDER. "Before going out one night, pull three cards with the intention of the cards giving you some forewarning about the evening. Let it be fun and easy and involve everyone! You can even ask, 'what happens if we go to this spot or this one?' Let the cards decide your night and see if they gave good advice!"
