Focal Point
You and a stranger. No way to talk. Can your minds still meet?
The game
Somewhere out there is a stranger. You will both answer the same eight questions. You can't talk, can't see each other, can't agree on anything in advance. You only win a round if you both land on the exact same answer.
Here is the trick: the stranger always reaches for the obvious choice, the one most people pick when they're trying to be found. So your job is not to be clever or original. It's the opposite. Think: what will they expect me to pick?
Why this works
In 1960 the economist Thomas Schelling asked people: you must meet someone in New York tomorrow, but you never agreed where or when. Most said the same place, at the same time, with no way to coordinate. He called that magnet answer a focal point. This is eight of them. Let's see how often your mind meets a stranger's.
