After reviewing factors implicated in the generation of delusional beliefs, we conclude that whilst a perceptual aberration coupled with a particular type of attri‐butional bias may be necessary to explain the specific thematic content of a bizarre delusion, neither of these factors, whether in isolation or in combination, is sufficient to explain the presence of delusional beliefs. In contrast to bias models (theories which explain delusion formation in terms of extremes of normal reasoning biases), we advocate a deficit model of (...) delusion formation–that is, delusions arise when the normal cognitive system which people use to generate, evaluate, and then adopt beliefs is damaged. Mere bias we think inadequate to explain bizarre delusions which defy commonsense and persist despite overwhelming rational counter‐argument. In particular, we propose that two deficits must be present in the normal cognitive system to explain bizarre delusions: (1) there must be some damage to sensory and/or attentional‐orient‐ing mechanisms which causes an aberrant perception–this explains the bizarre content of the causal hypothesis generated to explain what is happening; and (2) there must also be a failure of normal belief evaluation–this explains why a hypothesis, implausible in the light of general commonsense, is adopted as belief. This latter deficit occurs, we suggest, when an individual is incapable of suspending the natural favoured status of direct first‐person evidence in order to critically evaluate hypotheses, given equal pri‐ority whether based on direct or indirect sources of information. In contrast, delusions with ‘ordinary’ content may arise when a single deficit of normal belief evaluation occurs in the context of an extreme (but normal) attentional bias, thus causing failure to critically evaluate hypotheses based on misperceptions and misintrepretations of ambiguous (but ordinary) first‐person experience.

Paranormal beliefs are often divided between those that are central to traditional Christian doctrine, such as the belief in heaven and hell, and those that are commonly associated with the supernatural or occult, such as the belief in ESP and psychic healing. This study employs data from a recent nationwide random sample general population survey to catalog the social correlates of paranormal beliefs and to examine the relationships between religious and other paranormal beliefs. The results indicate that standard social background (...) factors do a poor job of accounting for who believes in paranormal phenomena and that the importance of specific background factors changes dramatically from phenomenon to phenomenon. The results also show that the correlations between belief in religious phenomena and other paranormal phenomena are largely insignificant. These findings call into question many prevailing theories about paranormal beliefs. (shrink)

Several measures of paranormal belief have been developed and employed by researchers of published work. Despite this, there is considerable debate about the nature and structure of paranormal belief. Particularly, authors remain uncertain about which belief subsets should be included within paranormal scales. The current study extended existing research by exploring shared variance across different paranormal measures. An extensive literature review was undertaken in order to identify measures of paranormal belief. The independent scale items were then combined to produce a (...) 124item composite measure. This was distributed in paper form and electronically via the Internet. Respondents were recruited face to face, by email, and by post. In total, 1,481 respondents completed the measure: 548 the paper version and 933 online. Exploratory factor analysis (principal components analysis) was performed, and a nine-factor structure emerged. This contained item clusters measuring belief in: Hauntings, Other Life, Superstition, Religious Belief, Alien Visitation, Extrasensory Perception (ESP), Psychokinesis (PK), Astrology, and Witchcraft. Keywords: paranormal beliefs—Paranormal Belief Scale (PBS)—R-PBS— Paranormal Short Inventory (PSI) —Australian Sheep–Goat Scale (ASGS)—Anomalous Experiences Inventory (AEI). (shrink)
