Religion and Supernatural Phenomena

The topic of religion and the credibility of supernatural experience has frequently been a source of debate within the public sphere. The prominent idea was that the more educated a person is, the more likely they are to question the supernatural. Recently, however, people have turned from the idea that education alone reduces the likelihood of being religious, and instead are focusing on individual factors such as differences in information processing and executive function.

The Dual Process Accounts of Reasoning Theory proposes that there are two distinctively separate cognitive systems that underlie thinking and reasoning. The first system, called “implicit” or unconscious reasoning, refers to the automatic or intuitive processing of information. When finding an optimal solution to a problem seems impossible or impractical, it’s thought that individuals use mental shortcuts (heuristics) to speed up the process. The second system is called “explicit” or conscious reasoning, and it performs the more slow, sequential, and rational thinking. An article by Time Magazine examined these different ways of processing information in relation to religiosity. Dr. David Rand, the director of Yale University's Human Cooperation Laboratory, conducted a study using the Cognitive Reflection Test to assess individuals’ likelihood to rely on heuristics when solving a riddle, rather than using deliberative, analytical thinking. He found that the frequency at which individuals gave intuitive answers was positively correlated with the strength of their religious beliefs. According to Rand, “some people have an intuitive tendency to attribute intention to the world around them: that somebody intended something to happen to you.” In contrast, a deliberative person is more likely to perceive that something happened to them as the result of a series of events, or as having no explanation.


Along with differences in ways that individuals tend to process information, impairment in certain neural structures has also been associated with greater religiosity, insofar as individuals are more likely to interpret ambiguous experiences as mystical or due to a supernatural phenomenon. The frontal cortex and temporal cortex (TC) are known to mediate cognitive (executive) and affective functions that might be relevant to the expression or inhibition of mystical experiences. It has been theorized that the down-regulation of the dorsolateral prefrontal cortex (dlPFC), which is involved in inhibitory control and error monitoring, could lead to a tendency to believe that certain sensorial experiences are mystical. An article entitled “Neural correlates of mystical experience” investigates this claim further. Cristofori, Bulbulia, Shaver, Wilson, Krueger, and Grafman proposed that selective damage to the dlPFC would be associated with greater mystical experiences, while lesions to the temporal cortex would result in fewer mystical experiences, due to the TC’s role in generating mystical experiences. They administered a measure of mystical experience (M-scale) to combat veterans, some of whom suffered from penetrating traumatic brain injury (pTBI) and some of whom did not (i.e., healthy controls), and then performed a voxel-based lesion-symptoms analysis (VLSM) on total M-scale scores between the two groups. Lesions in the frontal and temporal cortex (i.e., individuals in the pTBI group) were associated with higher M-scale scores. They also administered a Sorting test, which evaluates semantic verbal fluency and problem-solving, and found that the scores were negatively associated with M-scale scores for the pTBI group but not for the control group. This suggests that lower mysticism was associated with higher executive function performance. They then separated individuals from the pTBI group into subgroups based on whether the injury was to the dlPFC or TC, and compared them. Individuals with lesions in the dlPFC had a significantly lower score on the Sorting test than the healthy controls, but not compared to the TC group, and no difference was found between the TC group and the controls. Also, the mysticism scores for the dlPFC group were significantly higher as compared to the control group, but not compared to the TC group. Ultimately, results showed that an intact dlPFC is needed to regulate mysticism, due to its role in regulating executive functions.

Much research is still needed to further our understanding about how humans experience and form interpretations about the world. It is for this reason that phenomena that cannot easily be explained are likely to continue being a hot topic in the realms of both science and religion.
