Which cognitive bias explains jurors' failure to discount the external situation as determinant of behavior in confessions?

• A. Availability heuristic
• B. Hindsight bias
• C. Fundamental attribution error
• D. Confirmation bias

Answer: (C)

Fundamental attribution error is the tendency to explain someone’s actions by citing internal traits or dispositions while underestimating the influence of external circumstances. In the context of confessions, jurors who commit this bias focus on who the person is—their character, guilt, or honesty—rather than considering how the interrogation environment, pressure from authorities, manipulation, fear, or fatigue could have shaped the confession. This leads to discounting the external situation as a determinant of behavior and treating the confession as mainly a product of the person’s internal state, which can distort judgments about voluntariness and reliability. Other biases don’t fit this pattern as precisely. Availability bias is about judging likelihood based on what comes to mind quickly, not about overemphasizing internal causes. Hindsight bias involves believing outcomes were predictable after they occurred, not about attributing actions to internal traits versus situational factors. Confirmation bias is about favoring information that supports preconceptions, rather than systematically misattributing behavior to personal characteristics while ignoring situational influences.
