'Extrasensory perception (ESP) (or extra-sensory perception) is the apparent ability to acquire information by paranormal means independent of any known physical senses or deduction from previous experience. The term was coined by Duke University researcher J. B. Rhine to denote psychic abilities such as telepathy, precognition, Retrocognition, Intuition and Psychokinesis. ESP is also sometimes casually referred to as a sixth sense, gut instinct or hunch . The term implies sources of information currently unexplained by science.'
