What bias may lead investigators to incorrectly assume that a suspect is lying during an interrogation?

• A. Confirmation bias
• B. Lie bias
• C. Memory bias
• D. Availability heuristic

Answer: (B)

The bias that can lead investigators to incorrectly assume that a suspect is lying during an interrogation is lie bias. This bias occurs when investigators, based on prior experiences or generalizations about deceptive behavior, expect certain cues or behaviors to indicate dishonesty. As a result, they may misinterpret innocent behaviors—such as nervousness or evasion of eye contact—as signs of lying. This can lead to a distorted perception of the suspect's truthfulness, potentially resulting in unfair treatment or wrongful conclusions during the interrogation process. In the context of investigative practice, recognizing lie bias is crucial. It helps investigators approach interrogations with an open mind and a focus on the facts rather than preconceptions about what constitutes a "truthful" or "deceptive" demeanor. Being aware of this bias can improve the accuracy of evaluations and enhance the effectiveness of investigations.
