The fraudulent medium Ronald Edwin confessed he had duped his séance sitters and revealed the fraudulent methods he had used in his book Clock Without Hands (1955).[167] The psychical researcher Tony Cornell investigated the mediumship of Alec Harris in 1955. During the séance "spirit" materializations emerged from a cabinet and walked around the room. Cornell wrote that a stomach rumble, nicotine smelling breath and a pulse gave it away that all the spirit figures were in fact Harris and that he had dressed up as each one behind the cabinet.[168]


Before approaching a clairvoyant medium it would be a good idea to understand what a clairvoyant medium is, or, still better, what clairvoyant/ce and medium/ship stand for. ‘Clair’ means ‘clear’; and ‘voyant’ means ‘seeing’. The two meanings should be understood both literally and also figuratively with their extended meanings in psychic context. The terms ‘psychic’, ‘clairvoyant’ and ‘medium’ have interrelated, interdependent and overlapping interpretations. There may be some confusion about their implications in the minds of those who are new to the subject of psychics, or, are approaching the clairvoyant mediums for their advice and assistance for the first time.


In a series of experiments holding fake séances, (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]
