Over the past few decades, the number of Americans who identify as religiously unaffiliated—often referred to as “nones”—has grown rapidly. In the 1970s, only about 5% of Americans fell into this category. Today, that number exceeds 25%. Scholars have debated whether this change simply reflects a general decline in belief, or whether it signals something more complex. The research team wanted to explore the deeper forces at play: Why are people leaving institutional religion? What are they replacing it with? And how are their personal values shaping that process?
The role nutrition in fitness isn’t likely to change in twelve years; the role of, say, politics in affecting one’s religious affiliation absolutely will.
