The new study by the Pew Forum on Religion and Public Life, released this week, shocked many with the revelation that atheists and agnostics tend to know more about the world's religions than believers do.
Pew researchers asked more than 3,000 Americans 32 central questions about the Bible, Christianity and other world religions. On average, people who took the survey got half the answers wrong - and many even tripped on basic questions about their own faith.
