Theological incorrectness : why religious people believe what they shouldn't

Why do religious people believe what they shouldn't - not what others think they shouldn't believe, but things that don't accord with their own avowed religious beliefs?

Jason Slone terms this phenomenon 'theological incorrectness.' He argues that it exists because the mind is built in such a way that it's natural for us to think divergent thoughts simultaneously.

Human minds are great at coming up with innovative ideas that help them make sense of the world, he says, but those ideas do not always jibe with official religious beliefs.
