Tonight I decided to look up something I've been thinking about, which I heard about a few weeks ago in health class. Serotonin, a chemical in the brain, or something. I vaguely recalled hearing something about it's levels showing relevances to tendencies to follow logic and sound evidence, so I thought 'hm, maybe it might have something to do with religion, too, and the reasons why some people just won't respond to logic.'
Well, from what I could find, in a study of serotonin levels, the people with low levels of serotonin in one of the receptors had a higher tendency to have 'spiritual experiences', while the people with higher levels were the 'technician types' who believed only what they saw with their own eyes.
"There is more to say that low serotonin is linked with people who are open to spiritual or supernatural experiences," explained Farde. "Whereas the higher levels go more with people who believe what they see with their eyes and are not so open to God or other aspects of religion."
This page seems to be more concise, though.
Has anyone else heard anything about this?
