Even seemingly irrational beliefs can become ensconced in the social norms of a society. Research by biologists in the School of Arts and Sciences shows how.
Ancient Roman leaders once made decisions about important events, such as when to hold elections or where to build new cities, based on the presence or flight patterns of birds. Builders often omit the thirteenth floor from their floor plans, and many pedestrians go well out of their way to avoid walking under a ladder.
While it's widely recognized that superstitions like these are not rational, many persist, guiding the behavior of large groups of people even today.
In a new analysis driven by game theory, two theoretical biologists devised a model that shows how superstitious beliefs can become established in a society's social norms. Their work, which appears in Proceedings of the National Academy of Sciences, demonstrates how groups of individuals, each starting with distinct belief systems, can evolve a coordinated set of behaviors that are enforced by a set of consistent social norms.
