Religious participation seems to promote individual flourishing in a variety of interlocking ways, beginning with the friendships it fosters. In 2010, Chaeyoon Lim (of the University of Wisconsin-Madison) and Robert Putnam (of Harvard University) estimated that about half of the effect on satisfaction comes from deep and supportive relationships. The effects are also particularly strong with respect to marriage, with weekly service attenders being about 50 percent less likely to divorce than never-attenders. Religious participation also strongly protects against self-destructive behaviors: One of our studies found that, compared with never-attenders, regular attenders were substantially less likely (68 percent less likely for women, 33 percent less likely for men) to die from alcohol poisoning, drug overdose or suicide.
