Extrasensory perception

Extrasensory perception refers to the hypothesis that information can be acquired without passing through any of the five senses. The term was popularized by the American researcher Joseph Banks Rhine, who in 1934 published a book titled Extra-Sensory Perception, based on card-guessing experiments. It encompasses telepathy, clairvoyance and precognition. The laboratory experiments conducted since have not convinced the scientific community, and the subject remains controversial.
