Final answer:
The tendency to overestimate the extent to which a stranger's violent behavior stems from his or her aggressive personality is best illustrated by the fundamental attribution error.
Step-by-step explanation:
The tendency to overestimate the extent to which a stranger's violent behavior stems from his or her aggressive personality is best illustrated by the fundamental attribution error. This error refers to the tendency to attribute others' behavior to internal, dispositional causes rather than external, situational factors. For example, if someone sees a stranger behaving violently, they may assume that the person has an aggressive personality, overlooking the possibility that the behavior is being influenced by situational factors.
