Everyone's Suspicious of Atheists — Even Other Atheists

In the U.S. and plenty of other places around the world, atheism is on the rise. In just under half of the world's countries, according to Pew Research Center, the second-largest religious group is people who claim no religion at all. In the United States, while recent research has shown an uptick in the number of people who identify as atheist, definitive numbers are hard to come by; one survey last year put it around 10 percent, while a more recent study argued that it was as high as 26 percent.

Whatever the true number is, though, there remains a disconnect between atheism's popularity and its reputation: According to a new study published last week in Nature, people all over the world connect immorality with atheism.
