Pattern-Detection Machines

Our brains are tuned to find patterns in sequences, because in nature a pattern often signals something real: a predator's tracks, a change in weather, a ripening season. That instinct served our ancestors well. It backfires with dice, cards, and lottery draws, which carry no signal at all. The shape you "see" in a string of random results is invented by you, not stored in the events.

The fallacy is not limited to casinos. Investors expect stocks that have fallen to rebound. Sports fans expect teams on losing streaks to win. Any domain with randomness can trigger the fallacy. The instinct to see patterns where none exist is deeply wired.
