Whether you believe in God or not has nothing to do with how clever you are. Also just because people do believe it does not mean they are blinded in anyway, they are still normal rational people just as athiests are-IQ levels have nothing to do with faith.
Interesting... well I dunno-I find that that is a very vauge generalisation and not meaning to sound big headed but I'm not particually stupid and neither are many Christians I know... but you have a good point
well they could be, many aren't but thiests are usually blinded by their beliefs while athiests have more free will because they don't think they'll go to hell for questioning an invisible man in the sky. Thiests use god as an excuse for everything, so athiests hae the potential to be smarter but only some are.
Typically athiests have a better point as to why they don't agree with the Bible and why they don't believe. They seem to look more into depth in religious sort of things than do many people who believe. Most search out the reasons and in that study more so than some who are religious.
