"The study concludes that roughly one-quarter (26 percent) of Americans likely do not believe in God."

It's like I've been saying. Why go out and annoy folks by proselytizing when Big Mo's on your side, anyway?

Of course, the flip side is that one needn't believe in god to practice religion. Even Torquemada understood that.

Way More Americans May Be Atheists Than We Thought, by Daniel Cox (FiveThirtyEight)

... The authors of the study, published earlier this year, adopted a novel way to measure atheist identity. Instead of asking about belief in God directly, they provided a list of seemingly innocuous statements and then asked: “How many of these statements are true of you?” Respondents in a control group were given a list of nine statements, such as “I own a dog” and “I am a vegetarian.” The test group received all the same statements plus one that read, “I do not believe in God.” The totals from the test group were then compared to those from the control group, allowing researchers to estimate the number of people who identify as atheists without requiring any of the respondents to directly state that they don’t believe in God. The study concludes that roughly one-quarter (26 percent) of Americans likely do not believe in God.

While this result is fairly stunning and not consistent with any published survey results, there is good reason to suspect that more direct measures significantly underestimate the number of atheists.
