Final answer:
Kihye's family members are displaying the fundamental attribution error by attributing her unemployment to negative personality traits rather than considering external situational factors that may have led to her job loss and continued unemployment.
Step-by-step explanation:
The family members' perceptions of Kihye being irresponsible, unmotivated, and lazy are an example of the fundamental attribution error. This psychological concept explains the tendency to attribute someone's behavior to their character or personality, while underestimating the influence of external situational factors. Given Kihye's active job search and the hiring of a career coach, it's clear that these negative stereotypes do not reflect her reality. The family overlooks situational factors, like the job market and the company's closure, which could be contributing to her unemployment over these months.
