Walking Santa, Talking Christ

Why do Americans claim to be more religious than they really are :

Two in five Americans say they regularly attend religious services. Upward of 90 percent of all Americans believe in God, pollsters report more than 70 percent have absolutely no doubt that God exists. The patron saint of Christmas, Americans insist, is the emaciated hero on the Cross, not the obese fellow in the overstuffed costume.

There is only one conclusion to draw from these numbers: Americans are significantly more religious than the citizens of other industrialized nations.

Except they are not.

Beyond the polls, social scientists have conducted more rigorous analyses of religious behavior. Rather than ask people how often they attend church, the better studies measure what people actually do. The results are surprising. Americans are hardly more religious than people living in other industrialized countries. Yet they consistently—and more or less uniquely—want others to believe they are more religious than they really are.

Religion in America seems tied up with questions of identity in ways that are not the case in other industrialized countries. When you ask Americans about their religious beliefs, it's like asking them whether they are good people, or asking whether they are patriots. They'll say yes, even if they cheated on their taxes, bilked Medicare for unnecessary services, and evaded the draft. Asking people how often they attend church elicits answers about their identity—who people think they are or feel they ought to be, rather than what they actually believe and do.

The better studies ascertain whether people attend church, not what they feel in their hearts. It's possible that many Americans are deeply religious but don't attend church (even as they claim they do). But if the data raise serious questions about self-reported church attendance, they ought to raise red flags about all aspects of self-reported religiosity. Besides, self-reported church attendance has been held up as proof that America has somehow resisted the secularizing trends that have swept other industrialized nations. What if those numbers are spectacularly wrong?

To the data: There was an obvious clue (in hindsight) that the survey numbers were hugely inflated. Even as pundits theorized about why Americans were so much more religious than Europeans, quiet voices on the ground asked how, if so many Americans were attending services, the pews of so many churches could be deserted.

"If Americans are going to church at the rate they report, the churches would be full on Sunday mornings and denominations would be growing,". wrote Kirk Hadaway, now director of research at the Episcopal Church. (Hadaway's research has included evangelical congregations, which reported sharp growth in recent decades.)

Hadaway and his colleagues compared actual attendance counts with church members' reports about their attendance in 18 Catholic dioceses across the country and Protestants in a rural Ohio county.They found that actual "church attendance rates for Protestants and Catholics are approximately one half" of what people reported.

A few years later, another study estimated how often Americans attended church by asking them to minutely document how they spent their time on Sundays. Without revealing that they were interested in religious practices, researchers Stanley Presser and Linda Stinson asked questions along these lines: "I would like to ask you about the things you did yesterday from midnight Saturday to midnight last night. Let's start with midnight Saturday. What were you doing? What time did you finish? Where were you? What did you do next?"

This neutral interviewing method produced far fewer professions of church attendance. Compared to the "time-use" technique, Presser and Stinson found that nearly 50 percent more people claimed they attended services when asked the type of question that pollsters ask: "Did you attend religious services in the last week?"

In a more recent study Hadaway estimated that if the number of Americans who told Gallup pollsters that they attended church in the last week were accurate, about 118 million Americans would be at houses of worship each week. By calculating the number of congregations (including non-Christian congregations) and their average attendance, Hadaway estimated that in reality about 21 percent of Americans attended religious services weekly—exactly half the number who told pollsters they did.

Finally, in a brand new paper, Philip Brenner  the University of Michigan's Institute for Social Research compared self-reported attendance at religious services with "time-use" interviews in the United States, Canada, the Netherlands, Germany, France, Norway, Finland, Slovenia, Italy, Spain, Austria, Ireland, and Great Britain. Brenner looked at nearly 500 studies over four decades, involving nearly a million respondents.

Brenner found that the United States and Canada were outliers—not in religious attendance, but in overreporting religious attendance. Americans attended services about as often as Italians and Slovenians and slightly more than Brits and Germans. The significant difference between the two North American countries and other industrialized nations was the enormous gap between poll responses and time-use studies in those two countries.

Why do Americans and Canadians feel the need to overreport their religious attendance? You could say that religiosity for Americans is tied to their identity in a way that it is not for the Germans, the French, and the British. But that only restates the mystery. Why is religiosity tied to American identity?

 

Historians will point to the European roots of North American colonization. Many European settlers came to the New World in search of religious freedom, presumably because they cared more intensely about religion than did the brethren they left behind.

Perhaps. That answer feels unsatisfactory. I don't think religious intensity necessarily explains how religiosity becomes part of one's identity. Canada and the United States are quite different today in terms of their religious intensity and the importance they attach to the role of religion in public life, yet citizens in both countries greatly exaggerate their church attendance.

Whatever the reason for the disparity, here's the bottom line: For many Americans, church attendance is a central part of their lives. For others, it's a waste of time. If you're in either of these groups, more power to you. But in the spirit of Christmas and the truthteller whose message we celebrate, surely believers and atheists can agree on what to tell folks who talk Jesus but walk Santa: Enough with the two-faced posturing
