Extrasensory perception or ESP, also called sixth sense or second sight, 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, clairaudience, and clairvoyance, and their trans-temporal operation as precognition or retrocognition.
Parapsychology is the study of paranormal psychic phenomena, including ESP. Parapsychology has been criticized for continuing investigation despite being unable to provide convincing evidence for the existence of any psychic phenomena after more than a century of research. The scientific community rejects ESP due to the absence of an evidence base, the lack of a theory which would explain ESP and the lack of positive experimental results; it considers ESP to be pseudoscience.
