One Mistake and the Machine Is Fired
People watched a better algorithm miss one forecast and went back to a worse human. Six other experiments found people following machines more than people. Both results are real.
Two Cookies Left in the Jar
Identical cookies, identical jars. The two left in the jar were rated more valuable — and the price climbed highest when the jar had just dropped from ten.
One Named Child Beats Three Million Strangers
A seven-year-old girl with a name and a photograph outraised a famine affecting millions. Then researchers added the statistics to her story, and the donations went down. The follow-up studies are where it gets strange.
The Parts of the Plane With No Bullet Holes
In World War II, planners mapped the bullet holes on the bombers that came home and moved to armor the most-hit areas. A statistician pointed at the empty spots instead. The reason is a bug baked into every sample anyone ever builds.
The Seminarians Who Walked Past the Man in the Doorway
In 1973 researchers sent Princeton seminary students across a courtyard to give a talk, and put a slumped man in their path. What decided who stopped wasn't faith or the sermon topic. It was the clock.

In 1961 a graduate student asked people to make risky choices alone, then again as a group. The group didn't average out. It went further than anyone had chosen on their own.

Hand someone a lottery ticket and they will trade it away. Let them choose the numbers themselves and the odds do not change, but they do.

In 1961, the smartest men in Washington agreed on everything — and walked into a disaster. The next year the same men faced nuclear war and got it right. The difference was the room, not the people.
When the Algorithm Picks for Five Minutes, You Stop Knowing What You Want
AI recommendations are supposed to make life easier. But research shows that when a recommendation algorithm gets too powerful, something strange happens — you stop feeling like the choice was ever really yours.
