For centuries, the concept of a ‘hot hand’ has captivated the imagination. This phenomenon, also known as the “hot hand fallacy,” is a cognitive bias in which people assume that someone who has had success with a random event has an increased chance of continuing to be successful. Across various contexts, such as sports, gambling, and everyday life, this belief persists despite being widely accepted as untrue.

Exploring the history of hot hand inclination can help us better understand how this bias has impacted our understanding of probability. Ancient Greeks and Romans were familiar with the notion of “clinamen” or “swerve” – an idea that events could happen randomly and unpredictably – which was documented by Aristotle in his work “On Rhetoric” and Cicero in “De Oratore”. Additionally, superstitions about lucky charms were commonplace in Roman culture.

In modern times, Thomas Gilovich’s 1985 paper “Hot Hand in Basketball: On the Misperception of Random Sequences” demonstrated that players did not have any more success than would be expected from random chance alone; since then, numerous studies have explored its implications on our comprehension of probability and chance outcomes.

Evidently, hot hand inclination reveals how our perception of chance differs from what may be objectively true; despite knowing it does not reflect reality, we still cling onto it due to its influence on our view of possibility. By comprehending its origins, we can gain insight into how it affects our understanding of likelihoods and ultimately shape our perspective on probability going forward.



Ascertaining the concept of the “hot hand bias” can be a confounding notion. It is a cognitive aberration where people have an erroneous belief that someone who has had success with a random event has a greater possibility of having continued success in subsequent attempts. This phenomenon was initially brought to light by basketball analyst and statistician Tom Heinsohn in 1985, depicting it as a conviction that players could get into a “zone” where they were more likely to make shots. Despite numerous examinations indicating there is no proof for this effect, it still remains popularly accepted by many sports fans and players.

– History of Hot Hand Bias in Sports

Since the dawn of time, sports have been characterized by a mysterious phenomenon known as “hot hand bias”. Initially detected by psychologists Thomas Gilovich, Robert Vallone, and Amos Tversky in the early 80s when they delved into free-throw shooting data from the Philadelphia 76ers basketball team, it has since been subject to numerous investigations. Outcomes of these studies have varied; some have found proof of its presence in various sports, while others have suggested that streaks of success are simply a result of random luck.

Harvard researchers uncovered evidence for hot hand bias in NBA players when they discovered that those who had made two or more shots consecutively were more likely to make their third attempt than those who had missed two consecutive shots. Similarly, research has indicated that tennis players are also more likely to win a point after winning the previous one.

Regardless of the ongoing debate on this matter, it is clear that hot hand bias has been an integral part of sports psychology since its discovery decades ago and continues to be studied today.

– Historical Examples of Hot Hand Bias in Gambling

For centuries, people have thought that when it comes to gambling, luck can be a powerful force. This notion has been seen in various activities such as faro, craps and slot machines, where the belief that if one has had success in the past then they will continue to do so in the future is known as “hot hand bias”.

In 18th century France, playing faro was a popular pastime among high society. In this card game, players would bet on which card would be drawn from a deck. During this time period, many players would often put their money on cards that had previously won, convinced that they were “hot” and thus more likely to win again – an example of hot hand bias known as “streaking”.

The 19th century saw similar beliefs in America with the game of craps. Here players would wager on the outcome of rolling two dice; if one player had been successful with a certain roll (for example two sixes), then others would follow suit and bet heavily on it too, believing that its previous success rate made it more likely to come up than other combinations.

More recently, Las Vegas casinos have introduced slot machines which became incredibly popular due to their simplicity and potential for large payouts. People believed that if one machine had paid out recently then it was more likely to do so again due to its “hotness” or “luckiness”; this misguided thinking led to many people playing these machines more often than others despite their unchanged odds of winning regardless of recent payouts.

It is important for gamblers (and investors) alike to remember that past performance does not guarantee future results and luck plays an integral role in all forms of gambling (and investing). Hot hand bias is a concept which can lead people astray if they are not aware of it; understanding its implications is key in avoiding costly mistakes.

– History of Research on Hot Hand Bias

The concept of a “hot hand bias” was first brought to light in 1985 by Thomas Gilovich, Robert Vallone and Amos Tversky. This idea suggests that an individual’s performance after a successful event is more likely to be successful than what would be expected from random chance. Since then, numerous studies have been conducted to explore the validity of this phenomenon, with evidence pointing to its presence in certain situations.

Researchers have conducted experiments using basketball players shooting free throws, analyzing baseball batting statistics and running tests with participants playing dice games. All of these investigations indicate that there may be some form of hot hand bias at play. Furthermore, research has delved into the psychological implications of this effect; one study found that when individuals believe they are on a lucky streak, they become more confident and tend to take greater risks than usual.

It is clear that hot hand bias plays an important role in our decision-making processes and should not be overlooked when making any kind of gamble or investment strategy. With over 30 years having passed since its introduction, much progress has been made in understanding this phenomenon and its effects on our behavior.

– Historical Reactions to the Hot Hand Bias Phenomenon

For centuries, the notion of a “hot hand bias” has been a subject of intense debate in the world of sports and gaming. This idea suggests that a player’s performance can be determined by their recent successes or failures. Ancient Greek philosopher Aristotle was one of the first to comment on this phenomenon, claiming it was possible for luck to change over time and could be seen as skill. Later thinkers such as Thomas Hobbes and Jean-Jacques Rousseau also weighed in, with both agreeing that success is dependent on both luck and skill.

In recent years, academics have taken a more scientific approach to studying the hot hand bias. In 1985, Amos Tversky and Thomas Gilovich published a paper which argued against its existence; they found no evidence to suggest players were more likely to succeed after having achieved recent successes or failures. However, other researchers have since proposed alternative explanations for why people might believe in the hot hand effect, such as confirmation bias or selective memory recall.

Overall, opinions on the hot hand bias have shifted throughout history but remain inconclusive. While some maintain that players can influence their own luck through skill or other factors, others remain unconvinced by this notion. As research into this area continues, we may eventually gain greater understanding into how our beliefs about luck are formed and how they impact our behavior when playing sports or games.

– The Impact of Hot Hand Bias on the History of Decision Making

Throughout the annals of time, humans have been subject to a phenomenon that has had a major influence on decision-making: Hot Hand Bias. This bias is when people think they are more likely to succeed in a task based on their previous successes or failures. For instance, if someone rolls a die and obtains a six three times in succession, they may feel they are more probable to get another six on the next roll. Such an outlook can lead to irrational decisions and has been evident throughout history.

In ancient Greece, gambling games such as dice and heads or tails were heavily impacted by this bias. People believed that if they had won multiple times in a row, their luck would continue and it was sensible to keep placing bets on the same side. This led to people making choices based on superstition rather than logic, resulting in losses for many who could not resist being drawn in by the allure of hot hand bias.

The same type of thinking can be seen today with investments and stock markets. Investors often make decisions based on past successes instead of examining current market trends and data. This can result in large losses for those who rely too much on their own presumed “hot streak” instead of looking at the facts objectively.

To conclude, Hot Hand Bias has had an immense effect on the history of decision-making by convincing people to make selections based on superstition rather than fact-based research. It is important for investors and other decision makers to be aware of this phenomenon so that they can avoid being swayed by it when making crucial decisions.


For decades, there has been a great deal of discussion surrounding the concept of ‘hot hand bias’ in various sports, from basketball to baseball, soccer and football. The idea that someone who has had success in the past is more likely to have success in the future due to a streak of luck or skill is widely accepted, yet there remains a great deal of uncertainty as to its actual existence. Is this phenomenon real? Or merely an illusion? The debate rages on.
