Extrasensory perception or ESP, also called sixth sense, includes claimed reception of information not gained through the recognized physical senses, but sensed with the mind. The term was adopted by Duke University psychologist J. B. Rhine to denote psychic abilities such as intuition, telepathy, psychometry, clairvoyance, and their trans-temporal operation as precognition or retrocognition.[1]

Second sight is a form of extrasensory perception, whereby a person perceives information, in the form of a vision, about future events before they happen (precognition), or about things or events at remote locations (remote viewing).[2][3] There is no scientific evidence that second sight exists. Reports of second sight are known only from anecdotal evidence. Second sight and ESP are classified as pseudosciences.[4]
