Why Winning Streaks Feel More Predictive Than They Are
Why do we expect previous success to lead to future success?
Imagine a basketball player makes five shots in a row.
The crowd starts thinking:
“Give him the ball—he’s on fire!”
That belief is called the hot hand effect: the idea that recent success makes another success more likely.
The hot hand fallacy happens when we assume the streak itself proves that the person is now more likely to succeed again.
You see this outside sports too.
A trader has three profitable weeks and starts thinking:
“I’ve figured out the market.”
A salesperson closes several deals and assumes the next customer will be easy.
A gambler wins repeatedly and begins betting more aggressively.
The danger is that humans are very good at seeing patterns in randomness.
A streak can feel meaningful even when it may be partly luck.
But there’s an important nuance: later research has found that genuine “hot hand” effects can sometimes exist in sports and other skilled activities.
So the real mistake is not believing that momentum is impossible.
It is assuming that every streak proves momentum.
The lesson
When someone seems “hot,” ask:
“Has their underlying ability or situation actually changed—or am I just impressed by a short run of success?”
A streak may reveal skill.
Or it may simply be randomness wearing a convincing disguise.
