That is just awesome. Agnostics, first of all, are obsessed with religion (At least I am). I think it makes perfect sense that they would score better, because people who are less informed have more reason not to doubt their beliefs, but in my position I want to know everything, and the Bible just has too many holes in it. I know this, because I know a lot about it. I study what I believe, because I have to go against my own self-preservation to renounce the Bible. But for Christians it's easier. Don't know more than you have to, and you don't have to find out that there is a possibility of no after-life. I think a lot of people remain in the dark, so they don't have to face the truth. They know less for a reason. It's not just some BS survey. Once you become obsessed with the truth, you get closer to it.
