The separate roles of the reflective mind and involuntary inhibitory control in gatekeeping paranormal beliefs and the underlying intuitive confusions.

Intuitive thinking is known to predict paranormal beliefs, but the processes underlying this relationship, and the role of other thinking dispositions, have remained unclear. Study 1 showed that while an intuitive style increased and a reflective disposition counteracted paranormal beliefs, the ontological confusions suggested to underlie paranormal beliefs were predicted by individual differences in involuntary inhibitory processes. When the reasoning system was subjected to cognitive load, the ontological confusions increased, lost their relationship with paranormal beliefs, and their relationship with weaker inhibition was strongly accentuated. These findings support the argument that the confusions are mainly intuitive and that they therefore are most discernible under conditions in which inhibition is impaired, that is, when thinking is dominated by intuitive processing. Study 2 replicated the findings on intuitive and reflective thinking and paranormal beliefs. In Study 2, ontological confusions were also related to the same thinking styles as paranormal beliefs. The results support a model in which both intuitive and non-reflective thinking styles and involuntary inhibitory processes give way to embracing culturally acquired paranormal beliefs.

Is it just a brick wall or a sign from the universe? An fMRI study of supernatural believers and skeptics.

We examined with functional magnetic resonance imaging the brain activity of 12 supernatural believers and 11 skeptics who first imagined themselves in critical life situations (e.g. problems in intimate relationships) and then watched emotionally charged pictures of lifeless objects and scenery (e.g. two red cherries bound together). Supernatural believers reported seeing signs of how the situations were going to turn out in the pictures more often than skeptics did. Viewing the pictures activated the same brain regions among all participants (e.g. the left inferior frontal gyrus, IFG). However, the right IFG, previously associated with cognitive inhibition, was activated more strongly in skeptics than in supernatural believers, and its activation was negatively correlated to sign seeing in both participant groups. We discuss the implications of these findings for research on the universal processes that may underlie supernatural beliefs and the role of cognitive inhibition in explaining individual differences in such beliefs.
