Hot Hands
The hot hand (also known as the hot hand phenomenon or hot hand fallacy) is the putative tendency for an athlete to have streaks of success higher than their average performance. The concept is often applied to sports and skill-based tasks in general and originates from basketball, where a shooter is assumed to be more likely to score if their previous attempts were successful – i.e., while having the "hot hand". Researchers for many years did not find evidence for a "hot hand" in practice, dismissing it as fallacious. However, later research questioned whether the belief is indeed a fallacy. Some recent studies using modern statistical analysis have observed evidence for the "hot hand" in some sporting activities; however, other recent studies have not observed evidence of the "hot hand". Moreover, evidence suggests that only a small subset of players may show a "hot hand" and, among those who do, the magnitude (i.e., effect size) of the "hot hand" tends to be small.
