Have you ever heard someone say, ‘It’s gotta be my turn to win’? Or maybe you’ve found yourself thinking, ‘I’ve lost so many times, I’m bound to win soon.’ These are classic examples of the gambler’s fallacy, a cognitive bias that leads gamblers to believe that past outcomes influence future probabilities.

In this article, we will explore the psychology behind the gambler’s fallacy, understand why it occurs, and discuss the implications it has on gambling behavior. So, let’s dive in.

What is the Gambler’s Fallacy?

The gambler’s fallacy, also known as the Monte Carlo fallacy, is the mistaken belief that if something happens more frequently than usual during a given period, it will happen less frequently in the future, or vice versa. In other words, it is the belief that past outcomes can predict future outcomes, despite the independent nature of most gambling events.

An example of the gambler’s fallacy can be seen in a game of roulette. If the roulette wheel lands on black for several consecutive spins, a gambler may believe that red is now ‘due’ and more likely to occur in the next spin. However, each spin of the roulette wheel is an independent event with its own probability, and the previous outcomes do not affect the future outcomes.

Why Does the Gambler’s Fallacy Occur?

The gambler’s fallacy arises from our innate need to make sense of randomness and find patterns where there may not be any. Humans are wired to look for cause-and-effect relationships and often struggle to accept that some outcomes are purely random.

Additionally, our brains are wired to identify and remember patterns, even if they are not statistically significant. When we witness a series of consecutive outcomes, such as several losses in a row, we perceive a pattern and mistakenly believe that the next outcome will be different to restore balance. This desire for equilibrium fuels the gambler’s fallacy.

The Impact on Gambling Behavior

The gambler’s fallacy can have profound effects on gambling behavior. Believing in the fallacy can lead people to make irrational decisions and engage in risky behavior. For instance, a gambler may start increasing their bets after a series of losses, thinking that a win is due. This can lead to chasing losses and potentially spiraling into a gambling addiction.

Furthermore, the gambler’s fallacy can distort perceptions of risk. If someone believes that they are ‘due’ for a win, they may underestimate the likelihood of losing and overlook the reality of the game’s underlying probabilities. This can lead to poor decision-making and financial consequences.

Overcoming the Gambler’s Fallacy

Recognizing and overcoming the gambler’s fallacy is crucial for responsible gambling. Here are a few tips to help you avoid falling into this cognitive trap:

  • Understand probabilities: Educate yourself about the true nature of gambling probabilities. Each gambling event is independent, and past outcomes do not influence future outcomes.
  • Set limits: Establish clear limits on your gambling activities, including time and money. Stick to these limits to avoid chasing losses or getting caught up in the gambler’s fallacy.
  • Keep track of wins and losses: Maintaining a record of your gambling outcomes can help debunk the illusion of patterns and remind you of the true randomness of the game.
  • Focus on enjoyment: Instead of obsessing over winning or losing, shift your focus to the entertainment value of gambling. Treat it as a recreational activity rather than a source of income.

By adopting these strategies, you can approach gambling with a more rational mindset, making informed decisions based on the true nature of probabilities.


The gambler’s fallacy is a cognitive bias that can mislead gamblers into believing that past outcomes influence future probabilities. Understanding this fallacy is crucial for responsible gambling, as it can help individuals avoid irrational decisions and problematic behavior. By recognizing the true nature of probabilities and adopting strategies to overcome the fallacy, gamblers can approach their activities with a more rational mindset. So, remember, in the world of gambling, probability is king, and the past has no power over the future.
