The Definitive Expert in Deception Detection


Barry McManus is a leading expert in information elicitation, deception detection, behavioral assessment, interviews and interrogations. He served for more than 20 years as a CIA polygraph examiner and interrogator, including 10 years as the Agency’s Chief Polygraph Examiner.

After completion of a distinguished career with Clandestine Service of the Central Intelligence Agency, Mr. McManus joined Abraxas Corporation, an overseas business intelligence and consultancy company, as Vice President of Deception Detection Services in September 2003.  Building upon an extensive career in the Washington, D.C. Metropolitan Police Department centering on criminal and drug-related investigations, Mr. McManus transitioned to the Central Intelligence Agency where he developed deep expertise in deception detection and analysis through advanced academic study and sensitive professional training.  In varied worldwide responsibilities in U.S. interagency efforts to combat terrorism and protect sensitive intelligence programs and assets from counterintelligence approaches, Mr. McManus became recognized as a top-tier professional in the use of non-coercive interrogation, elicitation and interviewing techniques against hardened criminals, terrorists, and hostile intelligence agents. He received the Career Intelligence Medal in recognition of accomplishments in support of U.S. intelligence and national security policy.  In additional to Mr. McManus’s role in support of U.S. agency programs to combat terrorism, he specialized in teaching and training assignments of both junior and senior polygraph investigators and counterintelligence personnel, both within the U.S. Government as well as in collegiate teaching assignments. Through innovative management strategies he developed and implemented new programmic approaches to identifying and benchmarking the subtle, but distinct verbal and non-verbal behaviors that are essential to detection and prosecution of white collar and commercial fraud.

Mr. McManus holds a Bachelor of Arts degree in Sociology from Loyola College and a Master of Arts degree in Organizational and Security Management from Webster University. Mr. McManus is currently a doctoral candidate in Higher Education at George Mason University, where he studied abroad at Oxford University's prestigious Christ Church College.
