I guess that's the phenomenon of being "tempted to doubt." I have heard Christians talk about it and I have heard sermons on how to resist it. And as a Christian I was so tempted many times before I finally "committed the sin" of yielding to it.

It's an indoctrination. I was born into it. I didn't have a choice. Then I thought for myself.

There's gotta be something. Religious know just what to dodge to keep them from having to think too hard.

I think once you drink the kool-aid you have a pretty strong investment in whatever belief system you've signed up for and won't be swayed by mere facts or scientific evidence. At that point cognitive dissonance will keep you firmly in line at least until some drastic life event comes along that shows you a massive betrayal of your trust: murder, pedophilia, rape, etc.
