The psychologist and psychical researcher Stanley LeFevre Krebs had exposed the Bangs Sisters as frauds. During a séance he employed a hidden mirror and caught them tampering with a letter in an envelope and writing a reply in it under the table which they would pretend a spirit had written.[68] The British materialization medium Rosina Mary Showers was caught in many fraudulent séances throughout her career.[69] In 1874 during a séance with Edward William Cox a sitter looked into the cabinet and seized the spirit, the headdress fell off and was revealed to be Showers.[70]
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.[51]
Psychologists and researchers who studied Pearl Curran's automatic writings in the 1930s came to the conclusion Patience Worth was a fictitious creation of Curran.[152][153] In 1931 George Valiantine was exposed as a fraud in the séance room as it was discovered that he produced fraudulent "spirit" fingerprints in wax. The "spirit" thumbprint that Valiantine claimed belonged to Arthur Conan Doyle was revealed to be the print of his big toe on his right foot. It was also revealed that Valiantine made some of the prints with his elbow.[154]
Like common playing cards, the tarot has four suits (which vary by region: French suits in Northern Europe, Latin suits in Southern Europe, and German suits in Central Europe). Each suit has 14 cards, ten pip cards numbering from one (or Ace) to ten and four face cards (King, Queen, Knight, and Jack/Knave). In addition, the tarot has a separate 21-card trump suit and a single card known as the Fool. Depending on the game, the Fool may act as the top trump or may be played to avoid following suit.[1] These tarot cards, without occult symbology, are still used throughout much of Europe to play card games.
