Not really. The analogy would be if physicists know less about psychology. I'm sure that religious people tend to have more knowledge about their religion than atheists. When the questions span all religions and include several questions about history, not practice (e.g. Martin Luther), it turns into more or less just a test of general knowledge, which I would just expect better-educated people to win. I got thirteen out of fifteen (above average) and I couldn't give a hoot about religion one way or the other -- I sure as hell haven't done a "deep exploration of my faith" or whatever else.
