Storytelling allows us to make sense of the world. Research from a multitude of fields suggests that story structures match human neural maps. What do a mother breastfeeding, a hug from a friend, and a story all have in common? They all release oxytocin, also known as the love drug. And it’s powerful: In a study by neuroscientist Paul Zak, participants who were given synthetic oxytocin donated 57 percent more to charity than participants given a placebo. Similarly, hearing information in narrative form results in a higher likelihood of pro-social behavior.
