The Pew Forum recently reported survey results from asking Americans about the factors that influence a change in place of worship. See the overview here. Not surprisingly, moving residences figures prominently in why people change the place of worship.
But when searching, the most commonly cited factor in choosing the new place of worship is quality of service. Style of service is the third most cited factor. Both of these relate to what we in our class call the ideal strictness of the individual. Having friends or family in the congregation is also important, which matches the notion of religious capital.
