A psychic is a person who claims to use powers rooted in parapsychology such as extrasensory perception (ESP) to identify information hidden from the normal senses, particularly involving telepathy or clairvoyance, or who performs acts that are apparently inexplicable by natural laws, such as psychokinesis or teleportation. Although many people believe in psychic abilities, the scientific consensus is that there is no proof of the existence of such powers, and describes the practice as pseudoscience. The word "psychic" is also used as an adjective to describe such abilities.
Edgar Cayce (1877–1945) was a psychic of the 20th century and made many highly publicized predictions.
Clairvoyance is the claimed ability to acquire information that would be considered impossible to get through scientifically proven sensations, thus classified as extrasensory perception, or "sixth sense". Any person who is claimed to have such ability is said to be a clairvoyant.
