Study explores distrust of atheists by believers
The researchers concluded that religious believer's distrust -- rather than dislike or disgust -- was the central motivator of prejudice against atheists, adding that these studies offer important clues on how to combat this prejudice...
...The religious behaviors of others may provide believers with important social cues, the researchers say. "Outward displays of belief in God may be viewed as a proxy for trustworthiness, particularly by religious believers who think that people behave better if they feel that God is watching them," says Norenzayan. "While atheists may see their disbelief as a private matter on a metaphysical issue, believers may consider atheists' absence of belief as a public threat to cooperation and honesty."
