The Christian Science Monitor has reproduced the 32-question survey conducted by the Pew Forum on Religion and Public Life to gauge people’s knowledge of religion.
According to the Pew results:
On average, Americans got 16 of the 32 questions correct. Atheists and agnostics got an average of 20.9 correct answers. Jews (20.5) and Mormons (20.3). Protestants got 16 correct answers on average, while Catholics got 14.7 questions right.
Of those who took this test at the CSM website, the average correct score was higher, at 85% or 27.2 questions. This makes sense, I suppose. Only people who are interested in religion will bother to take a religion quiz.
It is a fairly low-level test and I was able to get all of them right.
