MediumshipMediumship is the practice of purportedly 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. Belief in psychic ability is widespread despite the absence of objective evidence for its existence. Scientific researchers have attempted to ascertain the validity of claims of mediumship.
Scientific skepticismScientific skepticism or rational skepticism (also spelled scepticism), 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 references the examination of claims and theories that appear to be beyond mainstream science, rather than the routine discussions and challenges among scientists.
Automatic writingAutomatic writing, also called psychography, is a claimed psychic ability allowing a person to produce written words without consciously writing. Practitioners engage in automatic writing by holding a writing instrument and allowing alleged spirits to manipulate the practitioner's hand. The instrument may be a standard writing instrument, or it may be one specially designed for automatic writing, such as a planchette or a ouija board.
SpiritualismSpiritualism was a social religious movement in the nineteenth century, according to which an individual's awareness persists after death and may be contacted by the living. The afterlife, or the "spirit world", is seen by spiritualists not as a static place, but as one in which spirits continue to evolve. These two beliefs—that contact with spirits is possible, and that spirits are more advanced than humans—lead spiritualists to the belief that spirits are capable of providing useful insight regarding moral and ethical issues, as well as about the nature of God.
OuijaThe Ouija (ˈwiːdʒə , -dʒi ), also known as a spirit board or talking board, is a flat board marked with the letters of the Latin alphabet, the numbers 0–9, the words "yes", "no", occasionally "hello" and "goodbye", along with various symbols and graphics. It uses a planchette (small heart-shaped piece of wood or plastic) as a movable indicator to spell out messages during a séance. Participants place their fingers on the planchette, and it is moved about the board to spell out words.
ClairvoyanceClairvoyance (klɛərˈvɔɪ.əns; ) is the claimed psychic ability to gain information about an object, person, location, or physical event through extrasensory perception. Any person who is claimed to have such ability is said to be a clairvoyant (klɛərˈvɔɪ.ənt) ("one who sees clearly"). Claims for the existence of paranormal and psychic abilities such as clairvoyance have not been supported by scientific evidence. Parapsychology explores this possibility, but the existence of the paranormal is not accepted by the scientific community.
Fads and Fallacies in the Name of ScienceFads and Fallacies in the Name of Science (1957)—originally published in 1952 as In the Name of Science: An Entertaining Survey of the High Priests and Cultists of Science, Past and Present—was Martin Gardner's second book. A survey of what it described as pseudosciences and cult beliefs, it became a founding document in the nascent scientific skepticism movement. Michael Shermer said of it: "Modern skepticism has developed into a science-based movement, beginning with Martin Gardner's 1952 classic".
GeomancyGeomancy is a method of divination that interprets markings on the ground or the patterns formed by tossed handfuls of soil, rocks, or sand. The most prevalent form of divinatory geomancy involves interpreting a series of 16 figures formed by a randomized process that involves recursion, followed by analyzing them, often augmented with astrological interpretations. Geomancy was also thought by figures such as Richard II to be a greater discipline that included philosophy, science, and alchemic elements.
Ideomotor phenomenonThe ideomotor phenomenon is a psychological phenomenon wherein a subject makes motions unconsciously. Also called ideomotor response (or ideomotor reflex) and abbreviated to IMR, it is a concept in hypnosis and psychological research. It is derived from the terms "ideo" (idea, or mental representation) and "motor" (muscular action). The phrase is most commonly used in reference to the process whereby a thought or mental image brings about a seemingly "reflexive" or automatic muscular reaction, often of minuscule degree, and potentially outside of the awareness of the subject.
ParanormalParanormal events are purported phenomena described in popular culture, folk, and other non-scientific bodies of knowledge, whose existence within these contexts is described as being beyond the scope of normal scientific understanding. Notable paranormal beliefs include those that pertain to extrasensory perception (for example, telepathy), spiritualism and the pseudosciences of ghost hunting, cryptozoology, and ufology.
