Hot hand fallacy

Reviewed by expert Scientifically proven

The hot hand fallacy is a cognitive bias that leads people to believe that a person who has experienced success in a particular task is more likely to experience continued success in that task, even if the success is due to chance. In other words, people tend to believe that something is "hot" or "lucky" and will therefore continue to be until the streak is broken, even if the previous success was simply due to chance. This bias can lead people to make erroneous decisions based on false beliefs about their own abilities or the abilities of others.

The Hot Hand Fallacy: Why We Believe in Streaks and Why We're Wrong

Have you ever seen a basketball player score three shots in a row and thought to yourself, "wow, they're really on fire"? Or maybe you've been on a winning streak in a game and felt like you couldn't lose? These feelings are common and show how the Hot Hand Fallacy, a cognitive bias, affects our perception of streaks or patterns.

What is the Hot Hand Fallacy?

The Hot Hand Fallacy is the belief that a person who has experienced success in a particular activity has a higher chance of continued success. This belief is based on the assumption that there's some sort of streak or pattern that influences success. For example, a basketball player who makes several shots in a row is thought to have a "Hot Hand".

However, research shows that this belief isn't supported by the evidence. Studies of basketball shooting, for example, show that there's no evidence of a Hot Hand effect. In other words, making several shots in a row doesn't increase a player's chances of making their next shot.

Why Do We Believe in the Hot Hand Fallacy?

So why do we continue to believe in the Hot Hand Fallacy even when there's no evidence to support it? One reason is that we tend to see patterns even when they don't exist. Our brains are wired to look for meaning in randomness, which is why we may think a player is on a streak when they're just making shots randomly.

Another reason is that we tend to remember when someone is successful more than when they fail. We're more likely to notice and remember a basketball player making several shots in a row than missing several in a row.

How the Hot Hand Fallacy Affects Our Decision Making

Believing in the Hot Hand Fallacy can affect our decision making in a variety of ways. One way is in gambling. Someone who believes in the Hot Hand may be more likely to place a bet on a player who has been successful in the past, even though there's no evidence that their success will continue.

The Hot Hand Fallacy can also affect our investment decisions. Someone who has been successful in the past may be more likely to invest in the stocks of the company they work for, even though there's no evidence that past success will continue.

How to Avoid the Hot Hand Fallacy

To avoid the Hot Hand Fallacy, it's important to remember that success in the past doesn't guarantee success in the future. Instead of looking for streaks or patterns, focus on the actual evidence of success. Look at a player's shooting percentage or a company's earnings, rather than just their past success.

Another way to avoid the Hot Hand Fallacy is to use data and statistics to make decisions instead of relying on intuition or gut feelings. By looking at the actual evidence, you can make more informed decisions and avoid falling victim to cognitive biases like the Hot Hand Fallacy.

Conclusion

The Hot Hand Fallacy is a cognitive bias that affects our perception of success and streaks. Despite the lack of evidence supporting the belief that success in the past guarantees success in the future, we continue to believe in the Hot Hand Fallacy. By understanding this bias and using data-driven decision making, we can avoid falling victim to the Hot Hand Fallacy and make better decisions.
