Went down the rabbit hole on this. Your brain treats a good story the same way it treats something happening to you. Not metaphorically.

On a brain scan, reading about someone running fires up the same motor regions as actually running. A Harvard study found we spend 47% of waking hours lost in things that aren’t real.

Your brain is wired to crave fiction. And there’s a reason.

Keith Oatley, a psychologist at the University of Toronto, calls fiction a “flight simulator for the mind.” I love that framing because it’s exactly right. When you read the word “coffee,” the part of your brain that processes real smells lights up. A 2006 study had people read scent words like “perfume” and neutral words like “chair” in a brain scanner. The smell regions only activated for scent words. Your brain didn’t care that the coffee wasn’t real.

It gets weirder. Paul Zak, a researcher at Claremont Graduate University, drew blood from people before and after they watched short videos. One told a story with an arc, a father and his dying son. The other was the same pair at a zoo. No storyline. The story version caused a spike in oxytocin, the chemical your brain releases when you bond with someone. The zoo version? Nothing. Zero oxytocin. And after the story ended, the high-oxytocin group voluntarily gave money to a stranger in the lab. Zak could predict who would give with 82% accuracy just from their blood.

A story changed how generous people were for the next hour.

In 2013, a team at Emory University scanned people’s brains every morning for 19 straight days while they read a novel each night. The changes were still visible the next morning, hours later, with nobody reading during the scan. Gregory Berns, who led the study, called it “shadow activity, almost like a muscle memory.” The changes showed up in the regions that handle physical touch and body sensation. The readers’ brains were rehearsing what it felt like to be inside someone else’s body.

I went looking for the evolutionary angle and found a 2017 study in Nature Communications that floored me. Researchers studied the Agta, a hunter-gatherer group in the Philippines going back over 35,000 years. They asked nearly 300 Agta across 18 camps to name their best storytellers, then measured cooperation. Camps with more skilled storytellers were measurably more cooperative. When the Agta were asked who they’d most want to live with, storytellers beat out the best hunters. Skilled storytellers had about 0.53 more living children on average. Across 89 stories from seven hunter-gatherer groups, 70% were specifically about how to cooperate and get along.

We didn’t invent fiction because we were bored. Groups that told stories survived. Groups that didn’t were worse at working together.

The planet has plenty going on. Your brain just evolved to need more worlds than one.

Vengo a recomendarles @OpenAudible para que descarguen su librería de Audible. Creo que si ya compraste un audiolibro lo de menos sería poder hacer con él lo que quieras, pero como no es el caso entonces herramientas como esta salen al quite. Pásenle: https://t.co/Uw37u2tOL8

Our Artemis II crew will be going around the Moon, but they'll always find their way back home 🌎

During this complex journey, the four astronauts will travel ~685,000 miles on a trajectory around the Moon and back to Earth.
