What are common results for sociopaths?
I saw one lady who looked plain and drab, next door neighbor type. Her attorney wanted her tested as she was charged with homicide. Her husband was in ICU due to arsenic poisoning with a feeding tube. He died from poisoning. Her polygraph was completely “Truthful” and she was lying all the way through it. It was only through skillful interrogation did she admit to the rat poisoning she put in pudding and fed him in the hospital. Later her two deceased children were exhumed and found to also have been poisoned. This was a sociopath...no conscience. Then we had the everyday thief and liar like Ruby who I took a 17 page confession from admitting to stealing and giving away several thousand dollars of cash and clothing from where she worked and as she is signing the confession she looked at me and asked “Do you think Mr.-— is going to fire me for this?” Her polygraph was clean but I had other evidence and a gut feel to interrogate, so yes there are many factors that influence the results of a polygraph.
Usually there are no physiological reactions, heart beat increase, respiration rate and range change, Galvanic skin response reaction as there is no fear present in the sociopath to lying...that is usually. Then there is the wild, inconclusive readings of ragged respiration, rapid heart rate, GSR all over the place...these also can occur. Each exam and person calls for close individual analysis.
