A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme. A meme acts as a unit for carrying cultural ideas, symbols, or practices, that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena with a mimicked theme. Supporters of the concept regard memes as cultural analogues to genes in that they self-replicate, mutate, and respond to selective pressures. In popular language, a meme may refer to an Internet meme, typically an image, that is remixed, copied, and circulated in a shared cultural experience online.
Memetics is a theory of the evolution of culture based on Darwinian principles with the meme as the unit of culture. The term "meme" was coined by biologist Richard Dawkins in his 1976 book The Selfish Gene, to illustrate the principle that he later called "Universal Darwinism". All evolutionary processes depend on information being copied, varied, and selected, a process also known as variation with selective retention. The information that is copied is called the replicator, and genes are the replicator for biological evolution. Dawkins proposed that the same process drives cultural evolution, and he called this second replicator the "meme". He gave as examples, tunes, catchphrases, fashions, and technologies. Like genes, memes are selfish replicators and have causal efficacy; in other words, their properties influence their chances of being copied and passed on. Some succeed because they are valuable or useful to their human hosts while others are more like viruses.
Parapsychology is the study of alleged psychic phenomena and other paranormal claims, for example, those related to near-death experiences, synchronicity, apparitional experiences, etc. Criticized as being a pseudoscience, the majority of mainstream scientists reject it. Parapsychology has also been criticised by mainstream critics for claims by many of its practitioners that their studies are plausible despite a lack of convincing evidence after more than a century of research for the existence of any psychic phenomena.
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.
The Society for Psychical Research (SPR) is a nonprofit organisation in the United Kingdom. Its stated purpose is to understand events and abilities commonly described as psychic or paranormal. It describes itself as the "first society to conduct organised scholarly research into human experiences that challenge contemporary scientific models." It does not, however, since its inception in 1882, hold any corporate opinions: SPR members assert a variety of beliefs with regard to the nature of the phenomena studied.
Telepathy is the purported vicarious transmission of information from one person's mind to another's without using any known human sensory channels or physical interaction. The term was first coined in 1882 by the classical scholar Frederic W. H. Myers, a founder of the Society for Psychical Research (SPR), and has remained more popular than the earlier expression thought-transference.
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.
An out-of-body experience is a phenomenon in which a person perceives the world from a location outside their physical body. An OBE is a form of autoscopy, although this term is more commonly used to refer to the pathological condition of seeing a second self, or doppelgänger.
Paranormal 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, spiritualism and the pseudosciences of ghost hunting, cryptozoology, and ufology.
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.
Astral projection is a term used in esotericism to describe an intentional out-of-body experience (OBE) that assumes the existence of a subtle body, known as the astral body or body of light, through which consciousness can function separately from the physical body and travel throughout the astral plane.
A debunker is a person or organization that exposes or discredits claims believed to be false, exaggerated, or pretentious. The term is often associated with skeptical investigation of controversial topics such as UFOs, claimed paranormal phenomena, cryptids, conspiracy theories, alternative medicine, religion, or exploratory or fringe areas of scientific or pseudoscientific research.
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.
Marcello Truzzi was an American sociologist and academic who was professor of sociology at New College of Florida and later at Eastern Michigan University, founding co-chairman of the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP), a founder of the Society for Scientific Exploration, and director for the Center for Scientific Anomalies Research.
Christopher (Chris) Charles French is a British psychologist who is prominent in the field of anomalistic psychology, with a focus on the psychology of paranormal beliefs and anomalous experiences. In addition to his academic activities, French frequently appears on radio and television to provide a skeptical perspective on paranormal claims.
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.
James E. Alcock is Professor emeritus (Psychology) at York University (Canada). Alcock is a noted critic of parapsychology and a Fellow and Member of the Executive Council for the Committee for Skeptical Inquiry. He is a member of the Editorial Board of The Skeptical Inquirer, and a frequent contributor to the magazine. He has also been a columnist for Humanist Perspectives Magazine. In 1999, a panel of skeptics named him among the two dozen most outstanding skeptics of the 20th century. In May 2004, CSICOP awarded Alcock CSI's highest honor, the In Praise of Reason Award. The author of several books and peer reviewed journal articles, Alcock is also an amateur magician and a member of the International Brotherhood of Magicians.
In psychology, anomalistic psychology is the study of human behaviour and experience connected with what is often called the paranormal, with few assumptions made about the validity of the reported phenomena.
Telekinesis is a hypothetical psychic ability allowing an individual to influence a physical system without physical interaction. Experiments to prove the existence of telekinesis have historically been criticized for lack of proper controls and repeatability. There is no reliable evidence that telekinesis is a real phenomenon, and the topic is generally regarded as pseudoscience.
Piet Hein Hoebens was a Dutch journalist, skeptic, and critic of parapsychology.
