I'm an atheist. I do not believe in the supernatural. I scored a 93% on the quiz and only missed scoring 100% because I misread a question and it won't let you edit your answers. Atheists and Jews performed the best overall. Hispanic Catholics the worst. According to the Daily Telegraph story, the region of the US that performed the worst was the South, the most religious demographic group in the country by far.
I think this shows evidence of a trend we already knew about. Namely that education and religiosity are generally negatively correlated. The better educated you are, the less likely you are to be strongly religious.
I also think this shows evidence of something most atheists know but most religious people refuse to acknowledge. Most atheists have given a good deal more thought to religion than most religious people have.
From a political perspective this really shows where politicized religious conservatism is coming from. In contrast to how they see themselves, the religious right is not a movement of orthodox religious people trying to apply to policy the Bible's teachings honestly and faithfully. It is far more accurate to say that they claiming the Bible supports the social views that they hold independently of any serious religious consideration or examination. In short, they are little different how they come to their views than the semi-literate graduates of the madrasahs in the Middle East and South Asia. We who oppose the religious right have thought this for years. But now we have a little chance to say "we told you so."
