Stories can tap into our “patternicity,” that is, our need to see patterns and our pattern-seeking and pattern-matching ability.
In a folktale course I took last year, we learned about how folktales all share patterns that are characteristic of a true "story". I find it particularly interesting that even amongst different communities that are divided by geography, culture, or other factors, there are consistent and recurring themes that emerge in the stories we share. All remarkable or significant stories require conflict or tension and I think this speaks to our nature of being problem solvers. Our attention is often gained and kept by challenges to our beliefs, values, or knowledge.
