Final answer:
The statement is false because self-serving bias involves attributing negative outcomes to external factors. If Kwon blames himself, he is not showing a self-serving bias; he's potentially displaying self-effacing behavior by taking excessive responsibility for the group's failure.
Step-by-step explanation:
The statement given is false. Kwon showing a self-serving bias would involve him attributing the group's poor performance to external factors instead of taking responsibility. Self-serving bias tends to lead individuals to credit themselves for successes while blaming outside forces for failures. In the example provided, Kim blames the professor for his failure instead of admitting his lack of study and attendance, which showcases self-serving bias. Therefore, if Kwon blames himself for the group's poor class project, he is not displaying a self-serving bias but rather the opposite—possibly an example of self-effacing behavior or taking more than his share of the responsibility.
