Why do some stories become popular, retold for hundreds of years, while others are forgotten? Why do you see the particular stories that you see in your social media feed and on the news? How can we tell whether stories are true? And why are false stories so maddeningly popular?
Here I will look at stories as if they were biological organisms. Stories can’t reproduce themselves; they rely on humans for their survival and reproduction. In that sense, stories are symbiotic (or perhaps parasitic) in their relationship with humans. New stories are constantly being invented, using existing and novel devices and elements. They take as their subject matter factual happenings, imaginings, or both. They are transmitted and retold at different rates; most stories peter out and die, while a few sweep across the world in hours. They exhibit all the hallmarks for natural selection to act: variation, differential survival and reproduction, and heritability. Reproduction is complicated. Stories may transmit copies of themselves (reprintings, oral retellings), or they may transmit their traits to new generations of stories.
