If an experiment is repeated a large number of times, independently under identical conditions, then the proportion of times that any specified event occurs approximately equals the probability of the event's occurrence on any particular trial; the larger the number of repetitions, the better the approximation tends to be.

Let's first define some code to do our fair coin flip and also simulations of the fair coin flip. If you've ever been in a casino, the last statement will ring true for better or worse.

In statistics, it may involve basing broad conclusions regarding the statistics of a survey from a small sample group that fails to sufficiently represent an entire population.

Now let's take a look at another concept about random events: independence. The definition is basically what you intuitively think it might be:.

Going back to our fair coin flipping example, each toss of our coin is independent from the other. Easy to think about abstractly but what if we got a sequence of coin flips like this:.

What would you expect the next flip to be? This almost natural tendency to believe that T should come up next and ignore the independence of the events is called the Gambler's Fallacy :.

The gambler's fallacy, also known as the Monte Carlo fallacy or the fallacy of the maturity of chances, is the mistaken belief that, if something happens more frequently than normal during some period, it will happen less frequently in the future, or that, if something happens less frequently than normal during some period, it will happen more frequently in the future presumably as a means of balancing nature.

You might think that this fallacy is so obvious that no one would make this mistake but you would be wrong.

You don't have to look any further than your local casino where each roulette wheel has an electronic display showing the last ten or so spins [3].

Many casino patrons will use this screen to religiously count how many red and black numbers have come up, along with a bunch of other various statistics in hopes that they might predict the next spin.

Of course each spin in independent, so these statistics won't help at all but that doesn't stop the casino from letting people throw their money away.

Once the fourth flip has taken place, all previous outcomes four heads now effectively become one known outcome, a unitary quantity that we can think of as 1.

So the fallacy is the false reasoning that it is more likely that the next toss will be a tail than a head due to the past tosses and that a run of luck in the past can somehow influence the odds in the future.

This video, produced as part of the TechNyou critical thinking resource, illustrates what we have discussed so far. The corollary to this is the equally fallacious notion of the 'hot hand', derived from basketball, in which it is thought that the last scorer is most likely to score the next one as well.

The academic name for this is 'positive recency' - that people tend to predict outcomes based on the most recent event.

Of course planning for the next war based on the last one another manifestation of positive recency invariably delivers military catastrophe, suggesting hot hand theory is equally flawed.

Indeed there is evidence that those guided by the gambler's fallacy that something that has kept on happening will not reoccur negative recency , are equally persuaded by the notion that something that has repeatedly occurred will carry on happening.

Obviously both these propositions cannot be right and in fact both are wrong. Essentially, these are the fallacies that drive bad investment and stock market strategies, with those waiting for trends to turn using the gambler's fallacy and those guided by 'hot' investment gurus or tipsters following the hot hand route.

Each strategy can lead to disaster, with declines accelerating rather than reversing and many 'expert' stock tips proving William Goldman's primary dictum about Hollywood: "Nobody knows anything".

Of course, one of the things that gamblers don't know is if the chances actually are dictated by pure mathematics, without chicanery lending a hand.

Gamblers would see that it had come up black the past eight spins, marvel at the improbability, and feel in their bones that the tiny silver ball was now more likely to land on red.

To give people the false confidence they needed to lay their chips on a roulette table. The entire food chain of intermediaries in the subprime mortgage market was duping itself with the same trick, using the foreshortened, statistically meaningless past to predict the future.

Mike Stadler: In baseball, we often hear that a player is 'due' because it has been awhile since he has had a hit, or had a hit in a particular situation.

People who fall prey to the gambler's fallacy think that a streak should end, but people who believe in the hot hand think it should continue.

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.
