"Those who believe the Bible is the literal word of God did slightly worse than average, while those who say it is not the word of God scored slightly better."
This shouldn't shock us but just in case here is another juicy quote.
"Smith (the researcher) has a theory about why atheists did so well on the quiz - they have thought more about religion than most people..... The single strongest factor predicting how well a person does on the religious knowledge quiz is education - the more years of schooling a person has, the more they are likely to know about religion, regardless of how religious they consider themselves to be"
Soooo what you are saying is that the more one thinks about religion in general..... the less it makes sense. Stay in school punks!
