The 7 common signs of lying involve changes in verbal/vocal patterns (vagueness, repetition, excessive detail, pitch changes), inconsistent body language (fidgeting, covering mouth, stiff posture, lack of eye contact or too much), physiological stress indicators (heavy breathing, sweating, flushing), linguistic distancing (fewer "I" statements), delayed emotional responses, avoidance, and using truth-claiming phrases like "to be honest" to overcompensate.
