Signs That Indicate a Person is Lying

What the Machine Records:

• A decrease in the subject’s electrical resistance in their skin
• An increase in blood pressure, volume or heart rate
• Abnormal breathing patterns
   

Physical Signs That a Person is Lying:

• Stiff facial expressions (seem to remain too long, are delayed or don’t reach the eyes)
• Significant amount of contact with their face (scratching, touching, rubbing their eyes)
• No eye contact/too much eye contact
• Placing objects in between themselves and their accuser
• Making indirect statements in order to avoid lying
• Providing excess information which is not very relevant to the story
• Will avoid using contractions in order to seem more honest (“I did not” instead of “I didn’t”)
