In history and religion

Throughout history, there have been numerous places and times in which people have claimed themselves or others to be clairvoyant. In several religions, stories of certain individuals being able to see things far removed from their immediate sensory perception are commonplace, especially within pagan religions where oracles were used.
Prophecy In religion, a prophecy is a message that has been communicated to a person (typically called a '' prophet'') by a supernatural entity. Prophecies are a feature of many cultures and belief systems and usually contain divine will or law, or pr ...
often involved some degree of clairvoyance, especially when future events were predicted. This ability has sometimes been attributed to a higher power rather than to the person performing it.

During treatment, Race reportedly would go into trance and undergo a personality change, becoming fluent and articulate, and giving diagnosis and prescription for his own disease as well as those of others. Clairvoyance was a reported ability of some mediums during the spiritualist period of the late 19th and early 20th centuries, and psychics of many descriptions have claimed clairvoyant ability up to the present day. Early researchers of clairvoyance included William Gregory, Gustav Pagenstecher, and Rudolf Tischner. Clairvoyance experiments were reported in 1884 by

initiated a series of human subject studies to determine whether participants (the ''viewers'' or ''percipients'') could reliably identify and accurately describe salient features of remote locations or ''targets''. In the early studies, a human ''sender'' was typically present at the remote location, as part of the experiment protocol. A three-step process was used, the first step being to randomly select the target conditions to be experienced by the senders. Secondly, in the viewing step, participants were asked to verbally express or sketch their impressions of the remote scene. Thirdly, in the judging step, these descriptions were matched by separate judges, as closely as possible, with the intended targets. The term

and Richard Kammann attempted to replicate Targ and Puthoff's remote viewing experiments that were carried out in the 1970s at the Stanford Research Institute. In a series of 35 studies, they were unable to replicate the results so investigated the procedure of the original experiments. Marks and Kammann discovered that the notes given to the judges in Targ and Puthoff's experiments contained clues as to which order they were carried out, such as referring to yesterday's two targets, or they had the date of the session written at the top of the page. They concluded that these clues were the reason for the experiment's high hit rates. Marks was able to achieve 100 per cent accuracy without visiting any of the sites himself but by using cues.

claimed that a rejudging of the transcripts from one of Targ and Puthoff's experiments revealed an above-chance result. Targ and Puthoff again refused to provide copies of the transcripts and it was not until July 1985 that they were made available for study when it was discovered they still contained sensory cues. Marks and Christopher Scott (1986) wrote "considering the importance for the remote viewing hypothesis of adequate cue removal, Tart's failure to perform this basic task seems beyond comprehension. As previously concluded, remote viewing has not been demonstrated in the experiments conducted by Puthoff and Targ, only the repeated failure of the investigators to remove sensory cues." In 1982 Robert Jahn, then Dean of the School of Engineering at Princeton University wrote a comprehensive review of psychic phenomena from an engineering perspective. His paper included numerous references to remote viewing studies at the time. Statistical flaws in his work have been proposed by others in the parapsychological community and within the general scientific community.

phenomena do so for merely psychological reasons. According to David G. Myers (''Psychology,'' 8th ed.):
The search for a valid and reliable test of clairvoyance has resulted in thousands of experiments. One controlled procedure has invited 'senders' to telepathically transmit one of four visual images to 'receivers' deprived of sensation in a nearby chamber (Bem & Honorton, 1994). The result? A reported 32 percent accurate response rate, surpassing the chance rate of 25 percent. But follow-up studies have (depending on who was summarizing the results) failed to replicate the phenomenon or produced mixed results (Bem & others, 2001; Milton & Wiseman, 2002; Storm, 2000, 2003).

, had a longstanding offer of U.S. $1 million—"to anyone who proves a genuine psychic power under proper observing conditions" (Randi, 1999). French, Australian, and Indian groups have parallel offers of up to 200,000 euros to anyone with demonstrable paranormal abilities (CFI, 2003). Large as these sums are, the scientific seal of approval would be worth far more to anyone whose claims could be authenticated. To refute those who say there is no ESP, one need only produce a single person who can demonstrate a single, reproducible ESP phenomenon. So far, no such person has emerged. Randi's offer has been publicized for three decades and dozens of people have been tested, sometimes under the scrutiny of an independent panel of judges. Still, nothing. "People's desire to believe in the paranormal is stronger than all the evidence that it does not exist."
