Why is it important to establish a baseline before assessing deception during an interview?

• A. To ensure observed cues are not simply how the person normally behaves
• B. To verify the suspect's innocence
• C. To calibrate equipment
• D. To schedule the next interview

Answer: (A)

Establishing a baseline lets you compare how this person normally behaves with how they respond during the interview. Deception cues aren’t universal—people vary a lot in how they speak and move, especially under stress. By first observing neutral questions to map typical speech patterns, reaction times, gestures, eye contact, and tone, you create a reference point. Then, when you ask about the issue in question, you can judge whether observed cues are simply normal behavior for that person or deviations that might suggest deception. This approach reduces misinterpretation and avoids assuming that any nervous behavior means lying. It’s not about proving innocence, calibrating equipment, or scheduling the next meeting; it’s about making sense of cues in the context of the individual.
