In the typical deep trance, the medium may not have clear recall of all the messages conveyed while in an altered state; such people generally work with an assistant. That person selectively wrote down or otherwise recorded the medium's words. Rarely did the assistant record the responding words of the sitter and other attendants. An example of this kind of relationship can be found in the early 20th century collaboration between the trance medium Mrs. Cecil M. Cook of the William T. Stead Memorial Center in Chicago (a religious body incorporated under the statutes of the State of Illinois) and the journalist Lloyd Kenyon Jones. The latter was a non-medium Spiritualist who transcribed Cook's messages in shorthand. He edited them for publication in book and pamphlet form.
In a series of fake séance experiments (Wiseman et al. 2003) paranormal believers and disbelievers were suggested by an actor that a table was levitating when, in fact, it remained stationary. After the seance, approximately one third of the participants incorrectly reported that the table had moved. The results showed a greater percentage of believers reporting that the table had moved. In another experiment the believers had also reported that a handbell had moved when it had remained stationary and expressed their belief that the fake séances contained genuine paranormal phenomena. The experiments strongly supported the notion that in the séance room, believers are more suggestible than disbelievers for suggestions that are consistent with their belief in paranormal phenomena.
The Major Arcana (greater secrets), or trump cards, consists of 22 cards without suits: The Magician, The High Priestess, The Empress, The Emperor, The Hierophant, The Lovers, The Chariot, Strength, The Hermit, Wheel of Fortune, Justice, The Hanged Man, Death, Temperance, The Devil, The Tower, The Star, The Moon, The Sun, Judgement, The World, and The Fool. Cards from The Magician to The World are numbered in Roman numerals from I to XXI, while The Fool is the only unnumbered card, sometimes placed at the beginning of the deck as 0, or at the end as XXII.
A widely known channeler of this variety is J. Z. Knight, who claims to channel the spirit of Ramtha, a 30 thousand-year-old man. Others purport to channel spirits from "future dimensions", ascended masters, or, in the case of the trance mediums of the Brahma Kumaris, God. Other notable channels are Jane Roberts for Seth, Esther Hicks for Abraham, and Carla L. Rueckert for Ra.
In 1988, the magician Bob Couttie criticized the paranormal author Brian Inglis for deliberately ignoring evidence of fraud in mediumship. Couttie wrote Inglis had not familiarized himself with magician techniques. In 1990 the researcher Gordon Stein discovered that the levitation photograph of the medium Carmine Mirabelli was fraudulent. The photograph was a trick as there were signs of chemical retouching under Mirabelli's feet. The retouching showed that Mirabelli was not levitating but was standing on a ladder which was erased from the photograph.
