The Hot Hand

Definition of The Hot Hand

The “hot hand” phenomenon is the cognitive bias which causes individuals to believe that a sequence of successful events increases the probability of future success. For example, in the world of sports, a basketball player who scores several consecutive points may be perceived as being “on fire,” leading spectators and even the athlete to believe that their chances of scoring an additional basket are statistically improved. This belief holds regardless of the underlying probabilities of each independent event.

🔮 Wise Words: “Those who believe that they have a hot hand can often just be setting themselves up for a cold shower.”

The Hot Hand vs The Cold Hand

Examples of The Hot Hand

1. Basketball Shooting: A player makes five shots in a row, leading the team to believe the player cannot miss for the next shot. In reality, their next shot has the same probability of success.

2. Stock Market: An investor sees stocks rise for several days and believes their investment strategy is “on fire,” likely to continue performing well despite market trends suggesting otherwise.

3. Gambling: A gambler wins big at a blackjack table, convinced that their “luck” is about to yield even larger rewards, ignoring the formal odds in favor of perceived historical success.

Related Terms

• Cold Hand: The inverse of the hot hand; the belief that a sequence of failures signals continued poor performance.
• Gambler’s Fallacy: The mistaken belief that past independent events affect the probabilities of future outcomes.
• Representativeness Heuristic: A cognitive bias that leads individuals to assess probabilities based on how similar something is to a known example, rather than statistical reality.

Illustrative Example

Here’s a quick overview of how the hot hand works versus reality:

    graph TD;
	    A[Flipping a Coin] -->|3 Heads in a Row| B{Belief in Hot Hand}
	    B -->|60% Success Rate| C[Next Coin Flip]
	    B -->|50% Success Rate| D[Actual Probability]

Explanation: The hot hand belief (B) leads a person to think they have a 60% chance of winning following three heads. However, reality (D) doesn’t bend to belief; it remains a steady 50%.
