Physical Cues Need Context

No single body cue proves deception, and even clusters are reasons to ask better follow-ups, not verdicts. Self-touching, brief freezes, delayed answers, or fleeting facial expressions may reflect mental effort or emotion, but they can also come from anxiety, culture, fatigue, heat, or the stakes of the conversation.

The useful pattern is change from baseline. If someone who is normally relaxed suddenly becomes still, vague, and hesitant on one topic, slow down and clarify. Treat body language as context for inquiry, not a lie detector.
