Avoid relying on eye behavior alone; it is not a reliable lie detector
Look for clusters of changes, not a single eye movement
Notice unusually frequent blinking
Notice reduced blinking or a fixed stare
Watch for rapid shifts in gaze direction
Observe prolonged eye contact that feels forced
Observe avoiding eye contact more than usual for that person
Look for delayed eye contact after answering
Notice eyes that dart away when specific details are mentioned
Watch for widened eyes or tense eyelids
Notice squinting or narrowed eyes during answers
Observe inconsistent eye behavior across similar questions
Compare eye behavior with facial expression and body language
Compare eye behavior with voice changes and pauses
Pay attention to eye behavior only when the person is under stress
Remember that culture, shyness, anxiety, and neurodiversity can affect eye contact
Use direct, calm questions and look for consistency over time
