Final answer:
The poker player is demonstrating a self-serving bias by attributing their success to internal factors such as skill and luck, which is a cognitive bias used to maintain self-esteem. This is connected to the fundamental attribution error, where people frequently emphasize personal traits over situational elements.
Step-by-step explanation:
When a poker player credits their winning to being good at cards and having good luck, they are exhibiting a self-serving bias. This cognitive bias involves making internal attributions for success, meaning the individual attributes positive outcomes to their own character or abilities. Conversely, if they were to lose and blamed it on bad luck or unfairness, that would also align with a self-serving bias because they would be attributing failure to external factors.
This tendency is related to the fundamental attribution error, which is a broader cognitive bias where people tend to overemphasize personal characteristics and ignore situational factors when assessing others' behavior. In the context of a group activity like a game or a sport, this can manifest as a belief that one's success is due to inherent skills or effort (internal, stable, controllable factors), while a loss is attributed to external conditions beyond one's control (external, unstable, uncontrollable factors).
The self-serving bias serves to protect an individual's self-esteem by taking credit for positive events while deflecting blame for negative ones. This is a common psychological phenomenon across various scenarios, including sports, business, and personal achievements.
