Review Questions
How does the hot hand fallacy influence decision-making in sports contexts?
In sports, the hot hand fallacy influences players and coaches by leading them to believe that athletes experiencing a streak of success are more likely to continue performing well. For example, in basketball, if a player makes several shots in a row, coaches might choose to give them the ball more often under the assumption they will keep scoring. This can create an imbalance in team dynamics and strategy if it causes neglect of other players who may also be capable of scoring.
What are some consequences of the hot hand fallacy in financial decision-making?

This cognitive bias can cause individuals to make impulsive decisions, like buying stocks during a perceived upward trend without considering fundamental analysis or long-term data. As a result, investors may experience losses when the market corrects itself, highlighting the risks of relying on perceived patterns instead of factual information.
