Well, I’m apparently in the top 1% (Supposedly by quite a bit, though I’m a bit skeptical. Smart, sure, but not -that- smart…), and while I don’t really have religious beliefs, I have some spiritual beliefs. I also keep it ‘in check’, so to speak. I don’t speculate without reason to do so, and I make sure that what I think might be right doesn’t conflict with reality. Unfortunatly, answering a great number of important questions with “I don’t know” is somewhat unsatisfying, even if it’s the only reasonable answer.
Oh well…
In general, it seems like there is less religious tendancies in the smart people I know. They’re more likely to say “I don’t know” or the like, instead of taking one thing and believing it. Then again, I have a pretty small and odd group of friends, anyway But it does seem that the smarter the person is, the more questioning they are, and the less likely they are to believe something without more and more reason to do so. Some, of course, find this reason eventually.
