From Ruth Whippman in America the Anxious:

“Almost all the studies show that religious people tend to have a greater number of social ties and stronger and more supportive communities. When the studies control for the increased levels of social connection, the link between religion and happiness almost always disappears.”

This is my fav positive psychology book. The one I’d recommend to someone brand new to the subject. I dig Whippman’s skepticism, insights, journalistic bent, and British wit. Only complaint, she could use some working class friends.
