Precognition (from the Latin præ-, “prior to,” + cognitio, “a getting to know”) denotes a form of extrasensory perception wherein a person perceives information about places or events through paranormal means before they happen. A related term, presentiment, refers to information about future events that is perceived as emotions. These terms are considered by some to be special cases of the more general term clairvoyance.
Skeptics believe the concept of precognition to be the result of fraud or self-delusion and contend that selection bias is the cause of the belief that one has precognition where individuals remember the "hits" and forget the "misses". Skeptics contend that the human memory naturally has a tendency to remember coincidences more often than other non-coincidences and thus individuals tend to remember more frequently when they were correct about a future event and forget the instances when they were wrong.
J. W. Dunne, a British aeronautics engineer, undertook the first systematic study of precognition in the early twentieth century. In 1927, he published the classic An Experiment with Time, which contained his findings and theories. Dunne's study was based on his own precognitive dreams, which involved both trivial incidents in his own life and major news events appearing in the press the day after the dream. When first realizing that he was seeing the future in his dreams, Dunne worried that he was "a freak." His worries soon eased when he discovered that precognitive dreams are common; he concluded that many people have them without realizing it, perhaps because they do not recall the details or fail to properly interpret the dream symbols.[4] Joseph Banks Rhine and Louisa Rhine began the next significant systematic research of precognition in the 1930s at the Parapsychology Laboratory at Duke University. Rhine used card-guessing experiments in which the participant was asked to record his guess of the order of a card deck before the deck was shuffled.
London psychiatrist J. A. Barker established the British Premonitions Bureau in 1967, which collected precognitive data in order to provide an early warning system of impending disasters. Barker succeeded in finding a number of "human seismographs" who tuned in regularly to disasters, but were unable to accurately pinpoint the times. The Princeton Engineering Anomalies Research Lab is one of the more recent examples of attempts to study precognition, beginning in 1979, with precognitive experiments conducted in a variety of formats by various parapsychologists. This facility was closed in 2007.
