Game Theory
Schelling Point
You are supposed to meet a friend in a city you have never been to together. You forgot to pick a place. Your phones are dead. You both still need to find each other. Without thinking too hard about it, both of you will probably choose the same thing — the famous square, the central station, the cathedral steps. You did not coordinate. You each chose what you expected the other one to expect.
Many things in social life work this way. When you cannot talk, you reach for what you assume everyone else will reach for. The default is not just convenient — it is expected. Currencies, languages, which side of the road to drive on, the time of a wedding, the color of a stop sign — these are stable not because anyone is enforcing them, but because each of us expects the others to expect them. Coordination is held in place by mutual imagination.
Therefore
When you need many people to behave the same way without talking, do not write a rule. Make one option more obvious than the others — and let everyone reach for it on their own.
Schelling, 1960
Thomas Schelling, an economist working at Harvard in 1960, asked New Yorkers a deceptively simple question: if you have to meet a stranger in this city tomorrow, but you cannot communicate, where do you go and when? Most of them, with no hesitation, gave the same answer: the information booth at Grand Central Terminal, at noon. None of them had been told it was the right answer. None of them needed to be. They had each pictured the other person picturing the same place. He called it a focal point. The world, he came to believe, is held together by thousands of them.
