Have you ever been playing a game of basketball with friends and then you make a shot, and then you make the next one? Did your confidence suddenly go up, despite the fact that the chances of you making the shot again are exactly the same as they were before? You, my friend, have just fallen victim to the hot hand fallacy. \u00a0The hot hand fallacy is the belief that because a person has had a successful experience with one event they will be able to reproduce the same event with success again or vice versa where if they miss they are more likely to miss again. The hot hand fallacy has been accepted by the psychology community as a cognitive illusion. A mistake in processing and in pattern recognition, but what if the hot-hand fallacy is not a fallacy at all?<\/span><\/p>\n

<\/p>\n

The hot hand fallacy can be explained by defining cognitive control as the ability <\/span>to adaptively adjust to an ever-changing environment<\/a><\/span> by allocating resources towards attempting to making sense of the world around us for things, such as luck or making that bas<\/span>ketball shot. The information is stored and creates patterns through top-down processing. Top-down processing is how the brain uses the information that it already has stored to make predictions about the present or future stimulus. The hot-hand fallacy is an example of how top-down processing can oftentimes be erroneous because it relies on expectations and expectations can fail us. An example of the conflict between expectations and actuality is in the Stroop Task where participants are given a color written in another color then asked to inhibit what the word actually is and only pay attention to the color. The results of this study are that people have a slower response time versus cases where they only have to name the color.<\/p>\n

People\u2019s expectation is that the color of the word will not matter, while the actuality it is the thing that they must attend to. The original evidence for the hot-hand fallacy comes from a paper written by Gilovich, Vallone, and Tversky<\/a> where they describe how basketball fans believe that a players chance of making a shot increases when preceded by a successful shot versus an unsuccessful one. In their study, they recruited college students who were fans of basketball and asked them \u201cif a player has a better chance of making a shot after having made his last two or three shots.\u201d Researchers found that 95% of the participants agreed with the statement(Gilovich, T., Vallone, R., & Tversky, A. (1985)). In order to test if this fallacy applied to athletes, researchers examined data from the professional NBA basketball team the 76ers and according to their data the players were more likely to miss following making shot, which completely differs from the hypothesis presented in the hot hand fallacy.<\/p>\n

Demonstrates how the hot hand and cold hand fallacy were equally explored in the research about baseball pitchers URL: https:\/\/fivethirtyeight.com\/features\/baseballs-hot-hand-is-real\/<\/p><\/div>\n

Though there is evidence for this phenomenon, I discovered that psychologist, such as Duthoo, Wuhr, and Notebaert, do not feel as if the hot hand fallacy applies to all. Some research claims that pro athletes gradually become <\/span>unaffected by the successes and failures <\/span><\/a>after playing the sport for so long. They even go further to argue that rather t<\/span>han being motivated by the shots made, some pro athletes report that it is instead the losses motivate them to succeed. As well as articles, such as “<\/a>Baseball\u2019s Hot Hand is Real\u201d<\/a> \u00a0that claim hot-hand is measurable in pitchers by analyzing the velocity of the pitch even going as far to develop a system called the Hidden Markov Model<\/a> from data collected from MLB 2014-2015. It works by taking the velocity at which the pitcher delivers their peak performance and determines that when their fastballs are delivered at a lesser velocity than the normal peak performance that the pitcher is in \u201ccold hand\u201d. While when pitchers are pitching balls at their individual peak velocity they are in \u201chot hand\u201d. \u00a0After rummaging through all that data, their research found that when a pitcher is moving from a hot pitching state to a cold pitching state their\u00a0pitches are 2 miles per hour slower(Arthur, R., Mattews G. (2017)). Research such as this presents the possibility of the hot hand fallacy existing.<\/p>\n

 <\/p>\n

Psychologists have studied the hot-hand fallacy from a variety of appr<\/span>oaches. The evolutionary explanation for this phenomenon claims that when people were previously hunter-gatherers they needed to forge to find resources. Resources such as fruits, animals, and people tend to be found in bunches. From top-down processing, humans were able to conclude that one resource was an indication that more resources were around. Evidence for this theory has been discovered by going into pre-westernized communities that are described as \u201chunter-horticulturist\u201d(Wilke, A., Barrett, C.H. ( 2009)).<\/p>\n

Though we will never truly know the truth behind the hot hand fallacy, we can hope the next shot that we shoot will be the one that makes it in. <\/span><\/p>\n
