On average, participants in the survey answered correctly overall for half of the survey questions.
Atheists and agnostics scored highest, with an average of 21 correct answers, while Jews and Mormons followed with about 20 accurate responses. Protestants overall averaged 16 correct answers, while Catholics followed with a score of about 15.
Not surprisingly, those who said they attended worship at least once a week and considered religion important in their lives often performed better on the overall survey. However, level of education was the best predictor of religious knowledge. The top-performing groups on the survey still came out ahead even when controlling for how much schooling they had completed.
On questions about Christianity, Mormons scored the highest, with an average of about eight correct answers out of 12, followed by white evangelicals, with an average of just over seven correct answers. Jews, along with atheists and agnostics, knew the most about other faiths, such as Islam, Buddhism, Hinduism and Judaism. Less than half of Americans know that the Dalai Lama is Buddhist, and less than four in 10 know that Vishnu and Shiva are part of Hinduism."
