There are not many things that pull people together quite like religious beliefs. Sports pull us together when our kids are on the same team, when we are all in a stadium, or when two of us are wearing the right hat on an airplane, but those don’t make for strong ties that are lasting and uniting. Religion offers an entire worldview and set of corresponding behaviors that do create lasting ties between people who otherwise wouldn’t have much in common and wouldn’t likely interact for any significant time. Robin Hanson and Kevin Simler look at religion in their book The Elephant in the Brain to understand the ways that religious signaling, behaviors, and beliefs operate in ways that often go unnoticed.
They quote a few authors in a short section that stood out to me:
“Religion,” says Jonathan Haidt, “is a team sport.”
“God,” says Emile Durkheim, “Is society writ large.”
Simler and Hanson go on to explain what this community and larger social aspect of religion means given that we tend to think of religion more as a private belief system:
“In this view, religion isn’t a matter of private beliefs, but rather of shared beliefs and, more importantly, communal practices. These interlocking pieces work together, creating strong social incentives for individuals to act (selfishly in ways that benefit the entire religious community. And the net result is a highly cohesive and cooperative social group. A religion, therefore, isn’t just a set of propositional beliefs about God and the afterlife; it’s an entire social system.”
Religions typically encourage pro-social behaviors that get people thinking more about a cohesive group than about selfish motives. By pursuing these prosocial behaviors, people can gain more status and prestige in society. For selfish reasons then (at least to some extent), people pursue the religious dictates of their society in their own personal lives. As they do this, positive externalities may arise and may create a society that is more cohesive and supportive all around. This might not always happen, but having a shared system of understanding the world, our places in the world, and the stories about who we are and why we exist help to create the social fabric and social capital to further encourage cooperation and social cohesion. In a weird way, our selfish motives encourage religion, even if we don’t acknowledge it and assume that religion is entirely about personal beliefs.
