What is the hot-hand fallacy?

It is the belief that someone on a winning streak is more likely to keep winning, even when each outcome is independent. We mistake the random streaks chance produces for real momentum.

What is the difference between the hot-hand fallacy and the gambler’s fallacy?

They are mirror errors. The hot-hand fallacy expects a streak to continue ("they’re hot"); the gambler’s fallacy expects it to break ("a reversal is due"). Both impose a pattern on independent, memoryless events.

Is the hot hand ever real?

In pure-chance settings like roulette, no — it is a fallacy. In some skill domains later research found small genuine streak effects, but they are far weaker than the strong "hot hand" people perceive.

Hot-hand fallacy

Judgement

The hot-hand fallacy is the belief that someone who has succeeded several times in a row is "on a streak" and more likely to succeed again — even when each attempt is statistically independent. We see momentum in what is really just chance.

Why it happens

The mind is a relentless pattern-detector and dislikes randomness, so it reads meaning into the runs that random processes naturally produce. A streak feels like evidence of a special state ("hot"), and we expect it to continue — confusing the memorylessness of chance with the momentum of skill.

Examples

Betting more on a gambler or basketball player who is "hot" after several wins or makes.
Assuming a fund manager with three good years has a winning touch that will persist.
Believing a roulette wheel that "ran hot" will keep favouring the same outcome.

How to counter it

Ask whether the events are actually independent — if so, past success says nothing about the next attempt.
Remember that random sequences contain streaks; a run is not proof of a cause.
Distinguish genuine skill (which persists) from luck (which doesn’t) by looking at long-run averages.

The deeper point

It and the gambler’s fallacy are one error wearing two masks: both refuse to accept that chance has no memory. Whether you expect the streak to break or to continue, you’re reading a story into noise that contains none.
