Which behavioral sign could suggest someone is being deceptive?

Avoiding eye contact is often associated with deceptive behavior because maintaining eye contact is typically a social norm that conveys honesty and engagement. When individuals are being deceptive, they may feel uncomfortable or guilty, leading them to avert their gaze as a way to avoid the scrutiny that comes with direct visual engagement. This behavior can signal to others that something is amiss, as it contrasts with the expected body language of someone who is truthful and at ease.

In contrast, consistent tone of voice, clear and confident responses, and direct answers to questions tend to indicate honesty and confidence in what a person is saying. These behaviors are generally associated with individuals who are forthcoming and genuine in their communication.
