[Serious] Link between brain damage and religious fundamentalism established

[Angrboda]

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.

The former is fine. The latter seems like reckless speculation unrelated to the substance of their research. The finding would appear to show that deficiencies in brain function can result in religious fundamentalism in some people. I think some might be tempted to then make the hasty generalization that deficiencies in brain function are at the root of religious fundamentalism in many, most, or all cases. That would be an error.
