The storytelling brain
Lesson 5 of 31 in the course “Brain Hacks”. Free, with animations and a quiz.
Your brain picks for you
Look at the picture. In the top row you read the middle sign as the letter B, in the bottom row as the number 13. But it’s the same sign! Autopilot picked the meaning from the neighbours and didn’t even tell you there was another option. It does this all the time: from scraps it quickly builds the most plausible picture. Usually that saves a ton of time. But sometimes the doubt you never even saw was the important part.
What you see is all there is
Autopilot builds a story only from what it has, and never asks what’s missing. In one experiment people read about a legal dispute. Some heard both sides, others just one, and they knew it was only one side. Those who heard one side were more confident in their opinion. Confidence depends on how neatly the story fits together, not on how much you know. Few facts but no contradictions, and the brain is happy.
The halo effect
A classic 1946 study. People got descriptions of two people using the same words, just in a different order. Alan: smart, hard-working, impulsive, critical, stubborn, envious. Ben: the same words, starting from the end. Alan was liked much more. The first traits colour everything after: “stubborn” in a smart person sounds like “principled”. That’s how first impressions work: a good-looking, confident new classmate seems smart and honest too, with zero data on that.
Question swapping
When a question is hard, autopilot quietly swaps it for an easy one and answers that. “Will this project take off in a year?” needs data on the team, market and competitors. But “Do I like the founder’s videos?” takes a second. Danya answers the second question and feels sure he answered the first. You can’t see the swap from inside: the answer just pops up with a feeling of “I know”. So it helps to ask yourself: which question did I actually just answer?
Experiment: dates and happiness
Students were asked two questions: how happy are you overall, and how many dates did you have last month. When the happiness question came first, there was almost no link between the answers. When the dating question came first, the link became strong. The fresh topic swapped the hard question “how’s my life?” for the easy “how’s my love life?”. Takeaway: don’t rate your whole life right after a bad day or a post that blew up.
To understand is to believe first
There’s a strong idea in psychology: to understand a sentence, the brain first believes it for a moment, and only then can it check and reject it. Checking is the pilot’s job. In 1990s experiments people saw false statements while being distracted, for example by having to watch a stream of digits at the same time. Busy people later took the false claims as true more often. That’s why scams often land when you’re tired, rushing or scrolling one-handed: the pilot doesn’t get the chance to say “stop”.
A neat story doesn’t mean true
A friend tells Danya: “Bought a coin at 0.01, now it’s worth 1. I just believed in the project.” The story is neat: belief → patience → reward. But Danya only hears from the winners. Hundreds of people who bought similar coins and lost don’t post about it. Autopilot doesn’t ask “who am I not hearing from?”; it sees one vivid story. Hack: before discussing with friends, write down your own opinion. That way you compare independent views instead of drifting toward the loudest one.
Try it: three “don’t knows”
Before any decision involving money or time, write down three things you don’t know. Before buying a coin, Danya wrote: who’s the team? where does the project’s revenue come from? who’s selling me this coin, and why? He couldn’t answer a single one, so the purchase waited. This list breaks “what you see is all there is”: it makes the pilot see the gaps in the story. Level complete: you now know how autopilot and pilot work. Next up: specific thinking bugs.
Check yourself
- The new kid is good-looking and confident, and you assume he’s smart and honest too. What happened?
Correct answer: The halo effect: the first impression coloured the rest. Yes. Like Alan and Ben: the first traits set the tone, and autopilot fills in the rest the same way with no data. - Danya has to judge whether a project will take off and thinks: “The founder’s videos are great, so yes.” What happened?
Correct answer: The hard question got swapped for the easy “do I like it?”. Right. Judging a project needs data on the team, market and revenue. Autopilot answered an easy question and passed it off as the answer to the hard one. - A friend told you only her side of a fight, and you’re sure who’s right. What’s smarter?
Correct answer: Ask yourself: what would the other side say?. Yes. Confidence grows with how neat the story is, not how complete. In the experiment, people who heard one side were more confident while knowing less. - A group of friends picks an idea for a project. How do you get honest opinions?
Correct answer: Everyone writes their view first, then discuss. Right. If views are written before the talk, they’re independent. Otherwise the first loud opinion becomes a “halo” and pulls everyone else along.
