Should You Buy Bread From the Busiest Bakery in Town?
Popularity explains behavior, not perfection.
Busy bakeries attract attention because they provide visible evidence that many customers made the same decision.
The hidden mechanism is information aggregation. Instead of evaluating every bakery independently, people often use the behavior of others as a shortcut.
Imagine a bakery with a long queue every morning. The crowd may indicate exceptional bread. It may also reflect a convenient location near commuters or a limited supply that creates visible demand.
A second-order effect appears when popularity itself attracts additional customers. The bakery becomes busy partly because people expect it to be busy.
People often think crowds identify the best bakery. More often, crowds identify the bakery that accumulated the strongest signals.
