What I find most fascinating is the possibility that it may work both ways. Trauma to the prefrontal cortex can impair mental flexibility, but apparently so can early indoctrination in fundamentalist ideology. In other words, extremist ideologies and religious fundamentalism may cause, if not brain damage, at least a significant reduction of cognitive potential. This is what science is hinting at. And it sure seems that way to this casual observer!

Brain damage or just a thorough brain washing?

The vast majority of the religious fundamentalism members is the fact that the overt shaken baby syndrome and the constant rocking motion used in the religious indoctrination of the very young children has lead to perpetual brain damage starting from birth!!!

Needs more peer review work done on it.

No doubt about it! There must be a reason that so many of us cling to conspiracy therosies/fundamentalist myths, etc! We do have a logical primate brain, after all!
