(RNS) A new study shows there may be more than twice as many atheists in the U.S. than previous studies have found.
The report by two University of Kentucky scholars suggests that because people may be embarrassed to admit they don't believe in God, the number of Americans who say they are non-believers may be artificially low. Polls from Gallup, Pew and Barna have reported that number between 3 and 10 percent.
“There’s a lot of atheists in the closet,” Gervais told Vox in an interview. “And ... if they knew there are lots of people just like them out there, that could potentially promote more tolerance.”
Gervais and Najle's work — which will be published in the next issue of the journal Social Psychological and Personality Science — shows that people are less likely to be truthful when answering a direct "yes or no" question about their faith, such as, "Do you believe in God?"
The pair polled two groups of people, asking each how many of several statements were true for them, such as "I am a vegetarian," "I own a dog," and "I believe in God."
One group -- 2,000 people -- received questionnaires with no query about God and another group -- 1,000 people -- received questionnaires that asked about belief in God.
By comparing the two groups -- and assuming the group not asked about God would have the same number of nonbelievers as the group asked about God -- Gervais and Najle conclude that the number of American atheists is usually under reported by most polls.
“According to our samples, about 1 in 3 atheists in our country don't feel comfortable disclosing their lack of belief,” Najle told Vox.
