Study uncovers how brain damage increases religious fundamentalism  discusses a recent study that found that “lesions in a particular brain region, the ventromedial prefrontal cortex,  tend to increase religious fundamentalism.” To cut to the chase, the authors review the functioning of this brain part and conclude: damage to the ventromedial prefrontal cortex appeared to cause an increase in religious fundamentalism by reducing cognitive flexibility – meaning the ability to update our beliefs in light of new evidence – along with lowering the personality trait of openness.

The article’s author concludes: “The new research helps elucidate the links between the functioning of the brain and religious belief. But there are many other factors, both physiological and psychological, that are in need of further study.”, 5-1-17
