It is also named Monte Carlo fallacy, after a casino in Las Vegas where it was observed in The Gambler's Fallacy line of thinking is incorrect because each event should be considered independent and its results have no bearing on past or present occurrences.

What Virat Kohli scores in the final has no bearing on scores in matches leading up to the big day. This fallacy arises in many other situations but all the more in gambling.

It gets this name because of the events that took place in the Monte Carlo Casino on August 18, The event happened on the roulette table.

One of the gamblers noticed that the ball had fallen on black for a number of continuous instances. This got people interested. Yes, the ball did fall on a red.

But not until 26 spins of the wheel. Until then each spin saw a greater number of people pushing their chips over to red.

While the people who put money on the 27th spin won a lot of money, a lot more people lost their money due to the long streak of blacks.

The fallacy is more omnipresent as everyone have held the belief that a streak has to come to an end. We see this most prominently in sports.

People predict that the 4th shot in a penalty shootout will be saved because the last 3 went in. Now we all know that the first, second or third penalty has no bearing on the fourth penalty.

And yet the fallacy kicks in. This is inspite of no scientific evidence to suggest so. Even if there is no continuity in the process. Now, the outcomes of a single toss are independent.

And the probability of getting a heads on the next toss is as much as getting a tails i. He tends to believe that the chance of a third heads on another toss is a still lower probability.

This However, one has to account for the first and second toss to have already happened. When the gamblers were done with Spin 25, they must have wondered statistically.

Statistically, this thinking was flawed because the question was not if the next-spin-in-a-series-ofspins will fall on a red. The correct thinking should have been that the next spin too has a chance of a black or red square.

A study was conducted by Fischbein and Schnarch in They administered a questionnaire to five student groups from grades 5, 7, 9, 11, and college students.

Under the Gambler's Fallacy, a person might predict that the next coin flip is more likely to land with the "tails" side up.

Each coin flip is an independent event, which means that any and all previous flips have no bearing on future flips. If before any coins were flipped a gambler were offered a chance to bet that 11 coin flips would result in 11 heads, the wise choice would be to turn it down because the probability of 11 coin flips resulting in 11 heads is extremely low.

The fallacy comes in believing that with 10 heads having already occurred, the 11th is now less likely. Risk Management.

It is also named Monte Carlo fallacy, after a casino in Las Vegas where it was observed in The Gambler's Fallacy line of thinking is incorrect because each event should be considered independent and its results have no bearing on past or present occurrences.

Investors often commit Gambler's fallacy when they believe that a stock will lose or gain value after a series of trading sessions with the exact opposite movement.

In practice, this assumption may not hold. For example, if a coin is flipped 21 times, the probability of 21 heads with a fair coin is 1 in 2,, Since this probability is so small, if it happens, it may well be that the coin is somehow biased towards landing on heads, or that it is being controlled by hidden magnets, or similar.

Bayesian inference can be used to show that when the long-run proportion of different outcomes is unknown but exchangeable meaning that the random process from which the outcomes are generated may be biased but is equally likely to be biased in any direction and that previous observations demonstrate the likely direction of the bias, the outcome which has occurred the most in the observed data is the most likely to occur again.

The opening scene of the play Rosencrantz and Guildenstern Are Dead by Tom Stoppard discusses these issues as one man continually flips heads and the other considers various possible explanations.

If external factors are allowed to change the probability of the events, the gambler's fallacy may not hold. For example, a change in the game rules might favour one player over the other, improving his or her win percentage.

Similarly, an inexperienced player's success may decrease after opposing teams learn about and play against their weaknesses.

This is another example of bias. The gambler's fallacy arises out of a belief in a law of small numbers , leading to the erroneous belief that small samples must be representative of the larger population.

According to the fallacy, streaks must eventually even out in order to be representative. When people are asked to make up a random-looking sequence of coin tosses, they tend to make sequences where the proportion of heads to tails stays closer to 0.

The gambler's fallacy can also be attributed to the mistaken belief that gambling, or even chance itself, is a fair process that can correct itself in the event of streaks, known as the just-world hypothesis.

When a person believes that gambling outcomes are the result of their own skill, they may be more susceptible to the gambler's fallacy because they reject the idea that chance could overcome skill or talent.

For events with a high degree of randomness, detecting a bias that will lead to a favorable outcome takes an impractically large amount of time and is very difficult, if not impossible, to do.

Another variety, known as the retrospective gambler's fallacy, occurs when individuals judge that a seemingly rare event must come from a longer sequence than a more common event does.

The belief that an imaginary sequence of die rolls is more than three times as long when a set of three sixes is observed as opposed to when there are only two sixes.

This effect can be observed in isolated instances, or even sequentially. Another example would involve hearing that a teenager has unprotected sex and becomes pregnant on a given night, and concluding that she has been engaging in unprotected sex for longer than if we hear she had unprotected sex but did not become pregnant, when the probability of becoming pregnant as a result of each intercourse is independent of the amount of prior intercourse.

Another psychological perspective states that gambler's fallacy can be seen as the counterpart to basketball's hot-hand fallacy , in which people tend to predict the same outcome as the previous event - known as positive recency - resulting in a belief that a high scorer will continue to score.

In the gambler's fallacy, people predict the opposite outcome of the previous event - negative recency - believing that since the roulette wheel has landed on black on the previous six occasions, it is due to land on red the next.

Ayton and Fischer have theorized that people display positive recency for the hot-hand fallacy because the fallacy deals with human performance, and that people do not believe that an inanimate object can become "hot.

The difference between the two fallacies is also found in economic decision-making. A study by Huber, Kirchler, and Stockl in examined how the hot hand and the gambler's fallacy are exhibited in the financial market.

The researchers gave their participants a choice: they could either bet on the outcome of a series of coin tosses, use an expert opinion to sway their decision, or choose a risk-free alternative instead for a smaller financial reward.

The participants also exhibited the gambler's fallacy, with their selection of either heads or tails decreasing after noticing a streak of either outcome.

This experiment helped bolster Ayton and Fischer's theory that people put more faith in human performance than they do in seemingly random processes.

While the representativeness heuristic and other cognitive biases are the most commonly cited cause of the gambler's fallacy, research suggests that there may also be a neurological component.

Functional magnetic resonance imaging has shown that after losing a bet or gamble, known as riskloss, the frontoparietal network of the brain is activated, resulting in more risk-taking behavior.

In contrast, there is decreased activity in the amygdala , caudate , and ventral striatum after a riskloss. Activation in the amygdala is negatively correlated with gambler's fallacy, so that the more activity exhibited in the amygdala, the less likely an individual is to fall prey to the gambler's fallacy.

These results suggest that gambler's fallacy relies more on the prefrontal cortex, which is responsible for executive, goal-directed processes, and less on the brain areas that control affective decision-making.

The desire to continue gambling or betting is controlled by the striatum , which supports a choice-outcome contingency learning method. The striatum processes the errors in prediction and the behavior changes accordingly.

After a win, the positive behavior is reinforced and after a loss, the behavior is conditioned to be avoided. In individuals exhibiting the gambler's fallacy, this choice-outcome contingency method is impaired, and they continue to make risks after a series of losses.

The gambler's fallacy is a deep-seated cognitive bias and can be very hard to overcome. Educating individuals about the nature of randomness has not always proven effective in reducing or eliminating any manifestation of the fallacy.

Participants in a study by Beach and Swensson in were shown a shuffled deck of index cards with shapes on them, and were instructed to guess which shape would come next in a sequence.

The experimental group of participants was informed about the nature and existence of the gambler's fallacy, and were explicitly instructed not to rely on run dependency to make their guesses.

The control group was not given this information. The response styles of the two groups were similar, indicating that the experimental group still based their choices on the length of the run sequence.

This led to the conclusion that instructing individuals about randomness is not sufficient in lessening the gambler's fallacy.

An individual's susceptibility to the gambler's fallacy may decrease with age. A study by Fischbein and Schnarch in administered a questionnaire to five groups: students in grades 5, 7, 9, 11, and college students specializing in teaching mathematics.

None of the participants had received any prior education regarding probability. The question asked was: "Ronni flipped a coin three times and in all cases heads came up.

Ronni intends to flip the coin again. What is the chance of getting heads the fourth time? Fischbein and Schnarch theorized that an individual's tendency to rely on the representativeness heuristic and other cognitive biases can be overcome with age.

Another possible solution comes from Roney and Trick, Gestalt psychologists who suggest that the fallacy may be eliminated as a result of grouping.

When a future event such as a coin toss is described as part of a sequence, no matter how arbitrarily, a person will automatically consider the event as it relates to the past events, resulting in the gambler's fallacy.

When a person considers every event as independent, the fallacy can be greatly reduced. Roney and Trick told participants in their experiment that they were betting on either two blocks of six coin tosses, or on two blocks of seven coin tosses.

The fourth, fifth, and sixth tosses all had the same outcome, either three heads or three tails. The seventh toss was grouped with either the end of one block, or the beginning of the next block.

Participants exhibited the strongest gambler's fallacy when the seventh trial was part of the first block, directly after the sequence of three heads or tails.

The researchers pointed out that the participants that did not show the gambler's fallacy showed less confidence in their bets and bet fewer times than the participants who picked with the gambler's fallacy.

When the seventh trial was grouped with the second block, and was perceived as not being part of a streak, the gambler's fallacy did not occur.

Roney and Trick argued that instead of teaching individuals about the nature of randomness, the fallacy could be avoided by training people to treat each event as if it is a beginning and not a continuation of previous events.

They suggested that this would prevent people from gambling when they are losing, in the mistaken hope that their chances of winning are due to increase based on an interaction with previous events.

Studies have found that asylum judges, loan officers, baseball umpires and lotto players employ the gambler's fallacy consistently in their decision-making.
