Paranormal is a general term that describes unusual experiences that supposedly lack a scientific explanation, or phenomena alleged to be outside of science's current ability to explain or measure. In parapsychology, it has, in the past, been used to describe the supposed phenomena of extra-sensory perception, including telepathy, and psychokinesis, ghosts, and hauntings. The term is also applied to UFOs, some creatures that fall under the scope of cryptozoology, purported phenomena surrounding the Bermuda Triangle, and other non-psychic subjects. Stories relating to paranormal phenomena are found in popular culture and folklore, but the scientific community, as referenced in statements made by organization such as the United States National Science Foundation, contends that scientific evidence does not support paranormal beliefs.
Approaching the paranormal from a research perspective is often difficult because of the lack of acceptance of the physical reality of most of the purported phenonema. By definition, the paranormal does not conform to conventional expectations of the natural. Despite this challenge, studies on the paranormal are periodically conducted by researchers all from various disciplines. Some researchers study just the beliefs in the paranormal regardless of whether the phenomena are considered to objectively exist. This section deals with various approaches to the paranormal: anecdotal, experimental, and participant-observer approaches, the skeptical investigation approach and the survey approach.
An anecdotal approach to the paranormal involves the collection of stories told about the paranormal. Such collections, lacking the rigour of empirical evidence, are not amenable to be subjected to scientific investigation. The anecdotal approach is not a scientific approach to the paranormal because it leaves verification dependent on the credibility of the party presenting the evidence. It is also subject to such logical fallacies as cognitive bias, inductive reasoning, lack of falsifiability, and other fallacies that may prevent the anecdote from having meaningful information to impart. Nevertheless, it is a common approach to paranormal phenomena.
Charles Fort (1874-1932) is perhaps the best known collector of paranormal anecdotes. Fort is said to have compiled as many as 40,000 notes on unexplained paranormal experiences, though there were no doubt many more than these. These notes came from what he called "the orthodox conventionality of Science", which were odd events originally reported in magazines and newspapers such as The Times and scientific journals such as Scientific American, Nature and Science. From this research Fort wrote seven books, though only four survive. These are: The Book of the Damned (1919), New Lands (1923), Lo! (1931) and Wild Talents (1932); one book was written between New Lands and Lo! but it was abandoned and absorbed into Lo!.
Reported events that he collected include teleportation (a term Fort is generally credited with coining); poltergeist events, falls of frogs, fishes, inorganic materials of an amazing range; crop circles; unaccountable noises and explosions; spontaneous fires; levitation; ball lightning (a term explicitly used by Fort); unidentified flying objects; mysterious appearances and disappearances; giant wheels of light in the oceans; and animals found outside their normal ranges (see phantom cat). He offered many reports of OOPArts, abbreviation for "out of place" artifacts: strange items found in unlikely locations. He also is perhaps the first person to explain strange human appearances and disappearances by the hypothesis of alien abduction, and was an early proponent of the extraterrestrial hypothesis.
Fort is considered by many as the father of modern paranormalism, which is the study of the paranormal.
The magazine Fortean Times continues Charles Fort's approach, regularly reporting anecdotal accounts of the paranormal.
Experimental investigation of the paranormal has been conducted by parapsychologists. Although parapsychology has its roots in earlier research, it began using the experimental approach in the 1930s under the direction of J. B. Rhine (1895 – 1980). Rhine popularized the now famous methodology of using card-guessing and dice-rolling experiments in a laboratory in the hopes of finding a statistical validation of extra-sensory perception.
In 1957, the Parapsychological Association was formed as the preeminent society for parapsychologists. In 1969, they became affiliated with the American Association for the Advancement of Science. That affiliation, along with a general openness to psychic and occult phenomena in the 1970s, led to a decade of increased parapsychological research. During this time, other notable organizations were also formed, including the Academy of Parapsychology and Medicine (1970), the Institute of Parascience (1971), the Academy of Religion and Psychical Research, the Institute for Noetic Sciences (1973), and the International Kirlian Research Association (1975). Each of these groups performed experiments on paranormal subjects to varying degrees. Parapsychological work was also conducted at the Stanford Research Institute during this time.
With the increase in parapsychological investigation, there came an increase in opposition to both the findings of parapsychologists and the granting of any formal recognition of the field. Criticisms of the field were focused in the founding of the Committee for the Scientific Investigation of Claims of the Paranormal (1976), now called the Committee for Skeptical Inquiry, and its periodical, Skeptical Inquirer. Eventually, more mainstream scientists became critical of parapsychology as an endeavor, and statements by the National Academies of Science and the National Science Foundation cast a pall on the claims of evidence for parapsychology. Today, many cite parapsychology as an example of a pseudoscience.
Though there are still some parapsychologists active today, interest and activity has waned considerably since the 1970s. To date there have been no experimental results that have gained wide acceptance in the scientific community as valid evidence of the paranormal.
Ghosts
For believers, ghosts are generally seen to be the spirit or soul of a deceased person.Alternative theories expand on that idea and include belief in the ghosts of deceased animals. Sometimes the term "ghost" is used synonymously with any spirit or demon, however in popular usage the term typically refers to a deceased person.
The belief in ghosts as souls of the departed is closely tied to the concept of animism, an ancient belief which attributed souls to everything in nature. As the nineteenth-century anthropologist James Frazer explained in his classic work, The Golden Bough, souls were seen as the creature within that animated the body. Although the human soul was sometimes symbolically or literally depicted in ancient cultures as a bird or other animal, it was widely held that the soul was an exact reproduction of the body in every feature, even down to clothing the person wore. This is depicted in artwork from various ancient cultures, including such works as the Egyptian Book of the Dead, which shows deceased people in the afterlife appearing much as they did before death, including the style of dress.
A widespread belief concerning ghosts is that they are composed of a misty, airy, or subtle material. Anthropologists speculate that this may also stem from early beliefs that ghosts were the person within the person, most noticeable in ancient cultures as a person's breath, which upon exhaling in colder climates appears visibly as a white mist. This belief may have also fostered the metaphorical meaning of "breath" in certain languages, such as the Latin spiritus and the Greek pneuma, which by analogy became extended to mean the soul. In the Bible, God is depicted as animating Adam with a breath.
Numerous theories have been proposed by scientists to provide non-paranormal explanations for ghosts sightings. Although the evidence for ghosts is largely anecdotal, the belief in ghosts throughout history has remained widespread and persistent.
The possibility of extraterrestrial life is not, by itself, a paranormal subject. Many scientists are actively engaged in the search for unicellular life within the solar system, carrying out studies on the surface of Mars and examining meteors that have fallen to Earth. Projects such as SETI are conducting an astronomical search for radio activity that would show evidence of intelligent life outside the solar system. Scientific theories of how life developed on Earth allow for the possibility that life developed on other planets as well. The paranormal aspect of extraterrestrial life centers largely around the belief in unidentified flying objects and the phenomena said to be associated with them.
Early in the history of UFO culture, believers divided themselves into two camps. The first held a rather conservative view of the phenomena, interpreting it as unexplained occurrences that merited serious study. They began calling themselves "ufologists" in the 1950s and felt that logical analysis of sighting reports would validate the notion of extraterrestrial visitation.
The second camp consisted of individuals who coupled ideas of extraterrestrial visitation with beliefs from existing quasi-religious movements. These individuals typically were enthusiasts of occultism and the paranormal. Many had backgrounds as active Theosophists, Spiritualists, or were followers of other esoteric doctrines. In contemporary times, many of these beliefs have coalesced into New Age spiritual movements.
Both secular and spiritual believers describe UFOs as having abilities beyond what is considered possible according to aerodynamics and physical laws. The transitory events surrounding many UFO sightings also limits the opportunity for repeat testing required by the scientific method. Acceptance of UFO theories by the larger scientific community is further hindered by the many possible hoaxes associated with UFO culture.
