Spirituality and the four Temperaments

It seems to me that a hypothesis correlating spirituality with the sections of the human brain (such as the "Triune Brain" concept), and related Temperaments, would correctly help understand on-goings. Recently I read that "spirituality unifies people, whereas religions divide them" or something to that effect. There are several major religions of the world currently, and each probably has sub-groups which could be called "fundamentalists"; other groups relate better to theologians or mystics. The Temperament theory of human typology behavior effects seems to have similar patterns: could the "Artisan" temperament be attracted to "fundamentalism" aspects of religions? That would explain the physical action united groupie focus on the present moment, with little comprehension of, or interest in, the future, and easily led by someone who tells them it is OK to be Artisan-like, the future will take care of itself and they being the saved chosen ones by virtue of group membership will come rescue them regardless of effects of whatever rivalrously they do to others, in their focus on "winning" against others. Maybe there also is some Guardian temperament in this, by justifying on "righteousness" regardless of position taken? Rationalist Temperaments would correlate to Theologians, it seems reasonable. Idealists would tend toward the mystics, seers of universality; whereas Artisans would focus on seers of near-present time and space information, such as some psychic perception as cast into the terms of the particular religion involved. The Temperaments seem a closely accurate model of ways individual people experience life and their world around them, so it is reasonable that it is also how they comprehend spirituality, God's relationships, a comprehension that affects their behavior.
