It means that open-mindedness presents a challenge; and since religious fundamentalism involves a strict adherence to a rigid set of beliefs, it would seem like the comfortable option for such an individual. This is why Dr. Grafman and his team predicted that participants with lesions to this region of the brain would score low on measures of cognitive flexibility and trait openness and high on measures of religious fundamentalism – which they did. These results suggest that damage to the vmPFC (prefrontal cortex region specific to cognitive flexibility) indirectly promotes religious fundamentalism by suppressing both cognitive flexibility and openness. In conclusion, these findings 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. What this means is that in some people, the system of “belief revision” may become suppressed due to brain damage.]
