When it comes to questions about faith and religion, who should you turn to if you need guidance? The answer will surprise you.

The Pew Forum on Religion and Public Life found most Americans are deeply ignorant about religion. More than 3,400 people were asked 32 questions about the Bible, Christianity, and other world religions, along with the principles in the Constitution governing religion. And it turns out the Americans who know the most are Atheist or Agnostic. Jewish people came in second, followed by Mormons, White evangelical Protestants and White Catholics. They're followed by White mainline Protestants, Black Protestants, and Hispanic Catholics.
