A link between brain damage and religious fundamentalism has now been established by scientists
Quote:journal Neuropsychologia has shown that religious fundamentalism is, in part, the result of a functional impairment in a brain region known as the prefrontal cortex. The findings suggest that damage to particular areas of the prefrontal cortex indirectly promotes religious fundamentalism by diminishing cognitive flexibility and openness—a psychology term that describes a personality trait which involves dimensions like curiosity, creativity, and open-mindedness.
According to Dr. Grafman and his team, since religious fundamentalism involves a strict adherence to a rigid set of beliefs, cognitive flexibility and open-mindedness present a challenge for fundamentalists. As such, they predicted that participants with lesions to either the vmPFC or the dlPFC would score low on measures of cognitive flexibility and trait openness and high on measures of religious fundamentalism.
The results showed that, as expected, damage to the vmPFC and dlPFC was associated with religious fundamentalism. Further tests revealed that this increase in religious fundamentalism was caused by a reduction in cognitive flexibility and openness resulting from the prefrontal cortex impairment.
These findings are important because they suggest that impaired functioning in the prefrontal cortex—whether from brain trauma, a psychological disorder, a drug or alcohol addiction, or simply a particular genetic profile—can make an individual susceptible to religious fundamentalism. And perhaps in other cases, extreme religious indoctrination harms the development or proper functioning of the prefrontal regions in a way that hinders cognitive flexibility and openness.
