What is the most reliable cue to deception?

Question

Quizplus · Accepted Answer

Research suggests that facial expressions are the most reliable cue to deception. Specifically, the facial muscles involved in emotional expression may reveal signs of deception, as individuals may try to control their facial expressions to conceal their true emotions. Other cues, such as gaze aversion or fidgeting, may also indicate deception, but they can also be explained by other factors and are not as reliable. Signs of nervousness may simply indicate anxiety or discomfort, rather than deception.
