Can you beat or trick the polygraph examination process or results? 

Measures to defeat the polygraph examination process and results are almost impossible.  

Many people think the polygraph examination process is faulty because different techniques are advertised claiming that they can be used to pass an examination.  

Dr. Stainback sustains yearly training in the latest methods to detect abnormal physical and behavioral techniques including the use of the latest equipment and computerized algorithms.   


Dr. Stainback leverages his extensive experience in National Security coupled with his certification as a Forensic Psychophysiologist (polygraph examiner) to perform state-of-the-art computerized polygraph examinations. Dr. Stainback uses the latest polygraph examination techniques and scoring methodologies  (Empirical Scoring System Multinominal – ESS-M). In addition,  Dr. Stainback is a continuous learner attending annual and advanced training in the polygraph examination field of practice. Dr. Stainback serves on multiple American Polygraph Association (APA) Committees and is an Associate Editor of Polygraph & Forensic Credibility Assessment: A Journal of Science and Field Practice.    

Dr. Stainback was not in law enforcement and considers this an important advantage over other polygraph examiners such as not being contentious, threatening or abrasive; not using powerful psychological ploys; or not using forceful interrogations during a polygraph examination.  Dr. Stainback considers empathetic listening, objectivity, flexibility, transparency and calmness, without being biased or judgmental, principal elements of a polygraph examination. 

Scientific credibility assessment testing (often and commonly referred to as a polygraph examination, polygraph exam, polygraph test, lie detector test, or lie detector) is a highly regarded and very accurate scientific test that is used extensively across the US Government, State and Law Enforcement agencies, and the private sector. The polygraph examination does not detect, or measure lies per se, but instead relies on the examiner's experience to interpret an examinee's test responses in order to make probabilistic conclusions if a person is being deceptive or not to specific issues of concern or trust issues.
