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.
Extrasensory perception (ESP), also known as a sixth sense, or cryptaesthesia, is a claimed paranormal ability pertaining to reception of information not gained through the recognized physical senses, but sensed with the mind. The term was adopted by Duke University botanist J. B. Rhine to denote psychic abilities such as intuition, telepathy, psychometry, clairvoyance, clairaudience, clairsentience, empathy and their trans-temporal operation as precognition or retrocognition.
Parapsychology is a field of research that studies a number of ostensible paranormal phenomena, including telepathy, precognition, clairvoyance, psychokinesis, near-death experiences, reincarnation, and apparitional experiences.
Fortune telling is the unproven spiritual practice of predicting information about a person's life. The scope of fortune telling is in principle identical with the practice of divination. The difference is that divination is the term used for predictions considered part of a religious ritual, invoking deities or spirits, while the term fortune telling implies a less serious or formal setting, even one of popular culture, where belief in occult workings behind the prediction is less prominent than the concept of suggestion, spiritual or practical advisory or affirmation.
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.
Palmistry is the pseudoscientific practice of fortune-telling through the study of the palm. Also known as palm reading, chiromancy, chirology or cheirology, the practice is found all over the world, with numerous cultural variations. Those who practice palmistry are generally called palmists, hand readers, hand analysts, or chirologists.
Cold reading is a set of techniques used by mentalists, psychics, fortune-tellers, and mediums. Without prior knowledge, a practiced cold-reader can quickly obtain a great deal of information by analyzing the person's body language, age, clothing or fashion, hairstyle, gender, sexual orientation, religion, ethnicity, level of education, manner of speech, place of origin, etc. during a line of questioning. Cold readings commonly employ high-probability guesses, quickly picking up on signals as to whether their guesses are in the right direction or not, then emphasizing and reinforcing chance connections and quickly moving on from missed guesses. Psychologists believe that this appears to work because of the Barnum effect and due to confirmation biases within people.
Scientific skepticism or rational skepticism, sometimes referred to as skeptical inquiry, is a position in which one questions the veracity of claims lacking empirical evidence. In practice, the term most commonly refers to the examination of claims and theories that appear to be beyond mainstream science, rather than the routine discussions and challenges among scientists. Scientific skepticism differs from philosophical skepticism, which questions humans' ability to claim any knowledge about the nature of the world and how they perceive it, and the similar but distinct methodological skepticism, which is a systematic process of being skeptical about the truth of one's beliefs.
Ray Hyman is a Professor Emeritus of Psychology at the University of Oregon in Eugene, Oregon, and a noted critic of parapsychology. Hyman, along with James Randi, Martin Gardner and Paul Kurtz, is one of the founders of the modern skeptical movement. He is the founder and leader of the Skeptic's Toolbox. Hyman serves on the Executive Council for the Committee for Skeptical Inquiry.
In parapsychology, psychometry, also known as token-object reading, or psychoscopy, is a form of extrasensory perception characterized by the claimed ability to glean accurate knowledge of an object's history by making physical contact with that object. Supporters assert that an object may have an energy field that transfers knowledge regarding that object's history.
Mediumship is the pseudoscientific practice of mediating communication between familiar spirits or spirits of the dead and living human beings. Practitioners are known as "mediums" or "spirit mediums". There are different types of mediumship or spirit channelling, including séance tables, trance, and ouija. The practice is associated with spiritualism and spiritism. A similar New Age practice is known as channeling.
Stanley Krippner is an American psychologist and parapsychologist. He received a B.S. degree from the University of Wisconsin–Madison in 1954 and M.A. (1957) and Ph.D. (1961) degrees from Northwestern University.
The Stone Tape Theory is the speculation that ghosts and hauntings are analogous to tape recordings: that mental impressions during emotional or traumatic events can be projected in the form of energy, "recorded" onto rocks and "replayed" under certain conditions. The idea draws inspiration from and shares similarities with views of 19th-century intellectualists and psychic researchers, such as Charles Babbage, Eleonor Sidgwick and Edmund Gurney. Contemporarily, the concept was popularized by a 1972 Christmas ghost story called The Stone Tape, produced by the BBC. Following the play's popularity, the idea and the term "stone tape" were retrospectively and inaccurately attributed to the British archaeologist turned parapsychologist T. C. Lethbridge, who believed that ghosts were not spirits of the deceased, but were simply non-interactive recordings similar to a movie.
