About Michael B. Lynch
Michael B. Lynch received the J.J. Heger Award from the American Polygraph Association in 1994 and was honored with the Al & Dorothea Clinchard Award in 2014 for extended, distinguished, devoted and unselfish service on behalf of the APA membership. Lynch holds a Master of Public Administration (MPA) degree and has served as school director for the Vollmer Polygraph training and education program. He has served as an Associate Editor for Polygraph & Forensic Credibility Assessment: A Journal of Science and Field Practice since at least 2017, contributing to the editorial oversight of the field's premier research publication.
Lynch's research contributions span both foundational historical work and contemporary applied polygraph science. His 1979 study with A. Markwart, "The Effect of Polygraph Evidence on Mock Jury Decision-Making," published in the Journal of Police Science and Administration, examined how polygraph test results influence jury deliberations, addressing critical legal and evidentiary questions about the role of psychophysiological detection in the courtroom. More recently, Lynch co-authored with Donald J. Krapohl and Mark Handler the "Terminology Reference for the Science of Psychophysiological Detection of Deception," 4th Edition (2022, published in European Polygraph in 2023), which established Lynch, Krapohl, and Handler as globally recognized authorities in the domain. This foundational reference documented the field's transformation from analog to digital polygraph technology and the shift from authority-based practices to evidence-based methodologies.
Lynch has maintained active involvement in the American Polygraph Association throughout his career, contributing to the organization's professional development and standardization efforts. His additional research includes work on clinical applications such as "Amnesia: Its detection by psychophysiological measures" (1980) and "A polygraphy examination of a sexually molested child" (1980), demonstrating expertise in specialized forensic applications of polygraph technology. His collaboration with co-authors Krapohl and Handler on the terminology reference represents one of the most significant standardization projects in modern polygraph science, as the work has been adapted internationally, including by the British Polygraph Society as the foundation for UK standards.

Terminology Reference for the Science of Psychophysiological Detection
The reference standardizes terminology across the polygraph profession, providing authoritative definitions grounded in peer-reviewed literature with 94 scientific references, facilitating communication between practitioners, researchers, and the broader scientific community. [002] 1981 PolygraphThe polygraph: a psychiatric resource
Lynch argued that the polygraph serves dual functions in psychiatric settings — both as a psychophysiological assessment tool and as a facilitator of patient disclosure — and identified specific clinical… [003] 1980 Bulletin of the American Academy of Psychiatry and the LawAmnesia: Its detection by psychophysiological measures
Personality-disordered patients were found deceptive at a rate of 63%, nearly five times the rate observed in patients with no major psychiatric illness, and shorter substance abuse histories were associated… [004] 1980 PolygraphA polygraphy examination of a sexually molested child
The case study demonstrated the feasibility of conducting a polygraph examination on a child sexual molestation victim and generating physiologically recordable data, contributing one of the earliest documented accounts of… [005] 1979 Bulletin of the A.A.P.L.Detection of deception: Its application to forensic psychiatry
[006] 1979 Canadian Journal of Behavioral ScienceA validity study of the psychological stress evaluator
The PSE could not reliably distinguish truthful from deceptive statements in controlled conditions, performing at chance levels and failing to exceed random guessing accuracy. [007] 1979 • JURY PERCEPTION Journal of Police Science and AdministrationThe Effect of Polygraph Evidence on Mock Jury Decision-Making
Found that polygraph evidence could be a crucial factor in jury decision-making. Raised concerns about potential for undue influence, contributing to judicial caution about admissibility.Explore all research.
