Why can't a single verbal or non-verbal cue reliably indicate deception during an interview?

• A. Interviews rely on a cluster of cues and a baseline, not a single cue.
• B. A single cue is definitive
• C. Only physical cues matter
• D. Interview bias invalidates all cues

Answer: (A)

Deception is not reliably signaled by just one cue. People vary a lot in how they respond under pressure, and the same cue can arise from nervousness, fatigue, cultural differences, or medical issues, not just deceit. Because there isn’t a universal tell that applies to everyone, the more reliable approach is to look for a pattern across multiple cues and compare what you’re seeing to that person’s usual behavior. When several indicators—verbal inconsistencies, changes in pace or tone, mismatches between what is said and how it’s said, and nonverbal signals that don’t fit the story—cohere with the context, the likelihood of deception being present is higher than if you relied on a single sign. Baseline behavior is essential because what’s normal for one person is not the same for another, helping you distinguish ordinary stress from deception-related changes. So, the best answer captures the idea of evaluating a cluster of cues against a baseline rather than trusting a single cue. A single cue is not definitive, because it can occur for many non-deceptive reasons. Focusing only on physical cues ignores the importance of verbal content and contextual factors. And while biases can distort judgment, they don’t erase the value of cue patterns; they just require careful, structured interpretation to avoid misreading them.
