Final answer:
Anthony is exhibiting negativity bias by focusing on negative events during a basketball game, neglecting positive outcomes and potentially creating a less enjoyable and supportive environment.
Step-by-step explanation:
Anthony is showing the cognitive bias of negativity bias. Negativity bias is the tendency to pay more attention to negative events than positive ones. Even while playing basketball, Anthony is focusing on the mistakes like turnovers or missed shots rather than on positive outcomes such as scoring or making a defensive stop. This type of cognitive bias can lead to a skewed perception of events, making Anthony more likely to recall negative experiences over positive ones while playing the game. This bias can adversely affect his enjoyment and possibly the performance of the whole team, as it can create a less supportive and more critical environment. Recognizing and countering this bias could improve Anthony's experience.
