Rodney Stark
Author Rodney Stark is a sociologist of religion, whose field of study is on the way religion affects how people and societies interact. He is an advocate of the application of the rational choice theory in the sociology of religion, which he calls the theory of religious economy. He, along with co-writer William Sims Bainbridge, developed the Stark-Bainbridge theory of religion, which explains religious devotion in terms of rewards and compensators. He himself has identified his religious beliefs as closely aligning with agnostics in the past.
