 note = {The hot hand phenomenon, where a successful outcome tends to lead better performance in following attempts, is often widely believed in traditional sports and gambling but considered as a cognitive bias. The present study aimed at examining whether the hot hand phenomenon or fallacy would exist in game plays. In the first part, we analyzed data from high-skill-level players in DOTA2 and found no substantial evidence supporting the hot hand phenomenon. In the second part, we conducted an online survey with questionnaires asking the beliefs in the hot hand phenomenon in game plays and participants' personality traits. The results revealed a general tendency to believe the hot hand phenomenon (i.e., better outcome will lead to better performance), with stronger belief correlating with higher agreeableness scores. The present study confirmed that the hot hand phenomenon is a fallacy and caused by a cognitive bias in game plays, which may be related to personality traits., The hot hand phenomenon, where a successful outcome tends to lead better performance in following attempts, is often widely believed in traditional sports and gambling but considered as a cognitive bias.
