was a well-known investigator of paranormal claims.
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
Occam's razor, which suggests that the simpler solution is usually the correct one. The
Committee for Skeptical Inquiry (CSI), formerly the Committee for the Scientific Investigation of Claims of the Paranormal (CSICOP), is an organization that aims to publicize the scientific, skeptical approach. It carries out investigations aimed at understanding paranormal reports in terms of scientific understanding, and publishes its results in the
Skeptical Inquirer magazine. CSI's
Richard Wiseman draws attention to possible alternative explanations for perceived paranormal activity in his article,
The Haunted Brain. 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. He was also the founder of the
James Randi Educational Foundation and its
million dollar challenge that offered a prize of $1,000,000 to anyone who could demonstrate evidence of any paranormal,
supernatural or
occult power or event, under test conditions agreed to by both parties. Despite many declarations of supernatural ability, the prize was never claimed.
Psychology In "anomalistic psychology", paranormal phenomena have naturalistic explanations resulting from
psychological and
physical factors, which have sometimes given the impression of paranormal activity to some people, in fact, where there have been none. The psychologist
David Marks wrote that paranormal phenomena can be explained by
magical thinking,
mental imagery,
subjective validation,
coincidence, hidden causes, and fraud. Research has also discovered that
cognitive bias is a factor underlying paranormal belief. , founder of the Anomalistic Psychology Research Unit. Many studies have found a link between
personality and
psychopathology variables correlating with paranormal belief. Some studies have also shown that
fantasy proneness correlates positively with paranormal belief. Bainbridge (1978) and Wuthnow (1976) found that the most susceptible people to paranormal belief are those who are poorly educated,
unemployed, or have roles that rank low among
social values. The alienation of these people due to their status in
society is said to encourage them to appeal to paranormal or magical beliefs. Research has associated paranormal belief with low
cognitive ability, low
IQ, and a lack of
science education.
Intelligent and highly educated participants involved in surveys have proven to have less paranormal belief. Tobacyk (1984) and Messer and Griggs (1989) discovered that college students with better
grades have less belief in the paranormal. In a case study (Gow, 2004) involving 167 participants, the findings revealed that psychological
absorption and
dissociation were higher for believers in the paranormal. Another study involving 100 students had revealed a positive correlation between paranormal belief and proneness to dissociation. A study (Williams
et al. 2007) discovered that "
neuroticism is fundamental to individual differences in paranormal belief, while paranormal belief is independent of extraversion and
psychoticism". A correlation has been found between paranormal belief and
irrational thinking. In an experiment Wierzbicki (1985) reported a significant correlation between paranormal belief and the number of errors made on a
syllogistic reasoning task, suggesting that believers in the paranormal have lower
cognitive ability. A relationship between
narcissistic personality and paranormal belief was discovered in a study involving the
Australian Sheep-Goat Scale. De Boer and Bierman wrote: A psychological study involving 174 members of the
Society for Psychical Research completed a delusional ideation questionnaire and a
deductive reasoning 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 beliefs. 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 having 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
ethnicity and paranormal belief. In a sample of American university students (Tobacyk
et al. 1988) it was found that
people of African descent have a higher level of belief in
superstitions and
witchcraft while belief in extraterrestrial life forms was stronger among
people of European descent. Otis and Kuo (1984) surveyed Singapore university students and found
Chinese,
Indian and
Malay students to differ in their paranormal beliefs, with the Chinese students showing greater skepticism. According to American surveys analysed by Bader
et al (2011)
African Americans have the firmest belief in the paranormal, and while the findings are not uniform, the "general trend is for whites to show lesser belief in most paranormal subjects". Polls show that about fifty percent of the United States population believes in the paranormal.
Robert L. Park says a lot of people believe in it because they "want it to be so". A 2013 study that utilized a biological motion perception task discovered a "relation between illusory pattern perception and supernatural and paranormal beliefs and suggest that paranormal beliefs are strongly related to agency detection biases".
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
fetal development. It was also realized that people with higher dopamine levels have the ability to find patterns and meanings where there are none. This is why scientists have connected high dopamine levels with paranormal belief.
Criticism Some scientists have criticized the
media 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 is constantly exposed to films, newspapers, documentaries, and books endorsing paranormal claims, while critical coverage is largely absent. According to
Paul Kurtz, "Regarding 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
magical thinking.
Terence Hines has written that on a personal level, paranormal claims could be considered a form of consumer fraud as people are "being induced through false claims to spend their money—often large sums—on paranormal claims that do not deliver what they promise" and uncritical acceptance of paranormal belief systems can be damaging to society. ==Belief polls==
