Indeed, but this is not unique to religious people. I've been deeply religious and I've been very secular, and one of the things I've learned is that smart people can believe incredibly dumb things.

The real hard question we each need to answer is to determine which really dumb things we believe despite our intelligence.

PS Isaac Newton spent a large portion of his life on alchemy and the hidden mysterious of the Bible. We all have blind spots, we just don't know they're there.
