Paranormal research

Approaching the paranormal from a research perspective is often difficult because of the lack of acceptable physical evidence from most of the purported phenomena. By definition, the paranormal (or supernatural) does not conform to conventional expectations of

. Therefore, a phenomenon cannot be confirmed as paranormal using the scientific method because, if it could be, it would no longer fit the definition. (However, confirmation would result in the phenomenon being reclassified as part of science.) Despite this problem, studies on the paranormal are periodically conducted by researchers from various disciplines. Some researchers simply study the

. Parapsychology has been criticized for continuing investigation despite being unable to provide convincing evidence for the existence of any psychic phenomena after more than a century of research. By the 2000s, the status of paranormal research in the United States had greatly declined from its height in the 1970s, with the majority of work being privately funded and only a small amount of research being carried out in university laboratories. In 2007, Britain had a number of privately funded laboratories in university psychology departments. Publication remained limited to a small number of niche journals, and to date there have been no experimental results that have gained wide acceptance in the scientific community as valid evidence of the paranormal.

through participant-observer approaches to the paranormal. Participant-observer methodologies have overlaps with other essentially qualitative approaches, including phenomenological research that seeks largely to describe subjects ''as they are experienced'', rather than to explain them. Participant observation suggests that by immersing oneself in the subject that is being studied, a researcher is presumed to gain understanding of the subject. Criticisms of participant observation as a data-gathering technique are similar to criticisms of other approaches to the paranormal, but also include an increased threat to the scientific objectivity of the researcher, unsystematic gathering of data, reliance on subjective measurement, and possible observer effects (i.e. observation may distort the observed behavior).

Skeptical scientific investigation

Scientific skeptics advocate critical investigation of claims of paranormal phenomena: applying the scientific method to reach a rational, scientific explanation of the phenomena to account for the paranormal claims, taking into account that alleged paranormal abilities and occurrences are sometimes hoaxes or misinterpretations of natural phenomena. A way of summarizing this method is by the application of

While he recognizes that approximately 15% of people believe they have experienced an encounter with a ghost, he reports that only 1% report seeing a full-fledged ghost while the rest report strange sensory stimuli, such as seeing fleeting shadows or wisps of smoke, or the sensation of hearing footsteps or feeling a presence. Wiseman makes the claim that, rather than experiencing paranormal activity, it is activity within our own brains that creates these strange sensations.

proposed that ghostly experiences could be explained by stimulating the brain with weak magnetic fields. Swedish psychologist Pehr Granqvist and his team, attempting to replicate Persinger's research, determined that the paranormal sensations experienced by Persinger's subjects were merely the result of suggestion, and that brain stimulation with magnetic fields did not result in ghostly experiences. Oxford University Justin Barrett has theorized that "agency"—being able to figure out why people do what they do—is so important in everyday life, that it is natural for our brains to work too hard at it, thereby detecting human or ghost-like behavior in everyday meaningless stimuli.

task. As predicted, the study showed that "individuals who reported a strong belief in the paranormal made more errors and displayed more delusional ideation than skeptical individuals". There was also a reasoning bias which was limited to people who reported a belief in, rather than experience of, paranormal phenomena. The results suggested that reasoning abnormalities may have a causal role in the formation of paranormal belief. Research has shown that people reporting contact with aliens have higher levels of absorption, dissociativity, fantasy proneness and tendency to hallucinate. Findings have shown in specific cases that paranormal belief acts as a psychodynamic coping function and serves as a mechanism for coping with stress. Survivors from childhood sexual abuse, violent and unsettled home environments have reported to have higher levels of paranormal belief. A study of a random sample of 502 adults revealed paranormal experiences were common in the population which were linked to a history of childhood trauma and dissociative symptoms. Research has also suggested that people who perceive themselves as having little control over their lives may develop paranormal beliefs to help provide an enhanced sense of control. The similarities between paranormal events and descriptions of trauma have also been noted. Gender differences in surveys on paranormal belief have reported women scoring higher than men overall and men having greater belief in UFOs and extraterrestrials. Surveys have also investigated the relationship between

Neuroscience

Some scientists have investigated possible neurocognitive processes underlying the formation of paranormal beliefs. In a study (Pizzagalli ''et al''. 2000) data demonstrated that "subjects differing in their declared belief in and experience with paranormal phenomena as well as in their schizotypal ideation, as determined by a standardized instrument, displayed differential brain electric activity during resting periods." Another study (Schulter and Papousek, 2008) wrote that paranormal belief can be explained by patterns of functional hemispheric asymmetry that may be related to perturbations during

Criticism

Some scientists have criticized the

for promoting paranormal claims. In a report by Singer and Benassi in 1981, they wrote that the media may account for much of the near universality of paranormal belief, as the public are constantly exposed to films, newspapers, documentaries and books endorsing paranormal claims while critical coverage is largely absent. According to
Paul Kurtz Paul Kurtz (December 21, 1925 – October 20, 2012) was an American scientific skeptic and secular humanist. He has been called "the father of secular humanism". He was Professor Emeritus of Philosophy at the State University of New York at Bu ...
, "In regard to the many talk shows that constantly deal with paranormal topics, the skeptical viewpoint is rarely heard; and when it is permitted to be expressed, it is usually sandbagged by the host or other guests." Kurtz described the popularity of public belief in the paranormal as a "quasi-religious phenomenon", a manifestation of a transcendental temptation, a tendency for people to seek a transcendental reality that cannot be known by using the methods of science. Kurtz compared this to a primitive form of

Belief polls

While the existence of paranormal phenomena is controversial and debated passionately by both proponents of the paranormal and by skeptics, surveys are useful in determining the ''beliefs'' of people in regards to paranormal phenomena. These opinions, while not constituting scientific evidence for or against, may give an indication of the mindset of a certain portion of the population (at least among those who answered the polls). The number of people worldwide who believe in parapsychological powers has been estimated to be 3 to 4 billion. A survey conducted in 2006 by researchers from Australia's

sought to determine the ''types'' of phenomena that people claim to have experienced and the effects these experiences have had on their lives. The study was conducted as an online survey with over 2,000 respondents from around the world participating. The results revealed that around 70% of the respondents believe to have had an unexplained paranormal event that changed their life, mostly in a positive way. About 70% also claimed to have seen, heard, or been touched by an animal or person that they knew was not there; 80% have reported having a premonition, and almost 50% stated they recalled a previous life.

in 2001."Smart People See Ghosts", Brad Steiger, ''Fate Magazine'', April 2006, p. 52–56; the unusual thing found by Farha and Steward was that belief in the supernatural increased with education level, contrary to many other surveys. However, that aspect of their study is not being used here. A survey by Jeffrey S. Levin, associate professor at Eastern Virginia Medical School, found that more than two thirds of the United States population reported having at least one mystical experience. A 1996 Gallup poll estimated that 71% of the people in the U.S. believed that the government was covering up information about UFOs. A 2002 Roper poll conducted for the Sci Fi channel reported that 56% thought UFOs were real craft and 48% that aliens had visited the

to be tested was George Valiantine, who claimed that in his presence spirits would speak through a trumpet that floated around a darkened room. For the test, Valiantine was placed in a room, the lights were extinguished, but unbeknownst to him his chair had been rigged to light a signal in an adjoining room if he ever left his seat. Because the light signals were tripped during his performance, Valiantine did not collect the award. The last to be examined by Scientific American was Mina Crandon in 1924.
