The standard narrative of American religious decline goes something like this: A few hundred years ago, European and American intellectuals began doubting the validity of God as an explanatory mechanism for natural life. As science became a more widely accepted method for investigating and understanding the physical world, religion became a less viable way of thinking—not just about medicine and mechanics, but also culture and politics and economics and every other sphere of public life. As the United States became more secular, people slowly began drifting away from faith.
Of course, this tale is not just reductive—it’s arguably inaccurate, in that it seems to capture neither the reasons nor the reality behind contemporary American belief. For one thing, the U.S. is still overwhelmingly religious, despite years of predictions about religion’s demise. A significant number of people who don’t identify with any particular faith group still say they believe in God, and roughly 40 percent pray daily or weekly. While there have been changes in this kind of private belief and practice, the most significant shift has been in the way people publicly practice their faith: Americans, and particularly young Americans, are less likely to attend services or identify with a religious group than they have at any time in recent memory.
