Charles Honts produced court-facing research that changed how judges weigh polygraph evidence, elevating the scientific standing of the lie detector test.
Charles R. Honts built one of the most extensive records of any polygraph researcher as both a scientist and an expert witness. His controlled studies on countermeasures, comparison question validity, and field accuracy provided the empirical foundation that attorneys relied on when arguing polygraph admissibility under the Daubert standard. This profile examines his training, landmark research, courtroom legacy, and why his work remains central to modern polygraph science.
TL;DR — The Short Version
- Honts trained under David Raskin at the University of Utah (1982–1986), one of the world's premier polygraph research programs, before establishing his own laboratory at Boise State University.
- His 2021 meta-analysis of the CQT — the largest ever conducted — coded 138 datasets and found CQT decisions in the median sample were 86% correct, with motivation level as a significant moderator of accuracy.
- His landmark 1994 study in the Journal of Applied Psychology showed both physical and mental countermeasures enabled approximately 50% of trained guilty subjects to defeat the polygraph — research that shaped examiner training and courtroom testimony worldwide.
- He has appeared as an expert witness more than 121 times in courts around the world, arguing that polygraph met Daubert admissibility standards, and co-authored the pivotal 1992 Law and Human Behavior article on polygraph admissibility challenges.

Early Life, Education & the University of Utah Connection
The Path to Polygraph Science
Charles R. Honts did not arrive at polygraph research through law enforcement training or government service. His journey was entirely academic, rooted in experimental psychology and a fascination with the measurement of physiological responses to psychological stimuli [1]Verified Charles Honts — ResearchGate Profile
Confirms Honts's affiliation with Boise State University, Professor Emeritus status, 79 publications, education at University of Utah 1982–1986, and DoDPI affiliation 1988–1990. This academic orientation distinguished him from many polygraph researchers who came from practitioner backgrounds and would prove essential to his later courtroom credibility.
Honts pursued his graduate education at the University of Utah from 1982 to 1986, entering what was arguably the most important polygraph research program in the world [1]Verified Charles Honts — ResearchGate Profile
Confirms Honts's affiliation with Boise State University, Professor Emeritus status, 79 publications, education at University of Utah 1982–1986, and DoDPI affiliation 1988–1990. The Utah program, led by David C. Raskin and John C. Kircher, represented a fundamentally different approach to polygraph research. While earlier pioneers like Cesare Lombroso had developed rudimentary physiological deception detection methods and Leonarde Keeler had patented the first polygraph instrument, the Utah team brought the rigor of modern experimental psychology to the field.
Under Raskin's mentorship, Honts learned to design controlled laboratory experiments using mock crime paradigms — carefully structured experimental protocols where some subjects committed a simulated crime while others did not. Examiners then attempted to distinguish between the two groups using standardized polygraph procedures. This approach allowed researchers to calculate precise accuracy rates because ground truth was known with certainty. The psychophysiological basis of the CQT that Honts studied at Utah would remain central to his entire career.
The Utah Research Tradition
The University of Utah program's key innovation was the development of computerized polygraph scoring algorithms that could be empirically validated against known outcomes [2]Verified Honts CV — Ninth Circuit Court Filing
Confirms Honts's complete publication record, DoDPI research reports, grants from Office of Naval Research, and contributions to Modern Scientific Evidence volumes. Rather than relying solely on human examiner judgment, the Utah team created mathematical models that analyzed physiological data objectively — including galvanic skin response (GSR) and other electrodermal activity (EDA) measures. Honts absorbed this quantitative approach thoroughly, and it became the foundation for everything he later accomplished at Boise State.
During his time at Utah, Honts also developed expertise in the comparison question test (CQT), the most widely used polygraph technique in criminal testing [3]Verified A Comprehensive Meta-Analysis of the Comparison Question Polygraph Test
Confirms the 2021 meta-analysis coded 138 datasets, found effect size of 0.69, significant moderator effects, and that CQT decisions in the median sample were 86% correct. The CQT had evolved from John Reid's 1947 innovation of the control question, and the theoretical basis of the CQT had been debated since its development. Honts would spend much of his career generating empirical data to support its validity.
His doctoral dissertation, completed under Raskin's supervision in 1986, focused on countermeasures and the physiological detection of deception [7]Verified The Polygraph and Lie Detection (NRC Report)
Confirms the 2003 National Research Council review of polygraph science, including citations to multiple Honts studies on countermeasures and CQT validity. This established the template for his future work: rigorous experimental methodology, careful control of variables, quantitative analysis of physiological data, and transparent reporting of results including error rates. This commitment to methodological rigor proved essential when he later testified in federal courts, where judges demanded the scientific transparency Honts had been trained to provide.
Building the Research Program at Boise State University
From DoDPI to Academia
After completing his training at Utah, Honts first served at the Department of Defense Polygraph Institute (DoDPI) from April 1988 to July 1990 [1]Verified Charles Honts — ResearchGate Profile
Confirms Honts's affiliation with Boise State University, Professor Emeritus status, 79 publications, education at University of Utah 1982–1986, and DoDPI affiliation 1988–1990.

Confirms the 2003 National Research Council review of polygraph science, including citations to multiple Honts studies on countermeasures and CQT validity.
Honts then joined the psychology faculty at Boise State University in Idaho, where he built a focused, productive laboratory dedicated specifically to polygraph and deception detection research [1]Verified Charles Honts — ResearchGate Profile
Confirms Honts's affiliation with Boise State University, Professor Emeritus status, 79 publications, education at University of Utah 1982–1986, and DoDPI affiliation 1988–1990. The laboratory enabled him to conduct controlled experiments that were difficult to perform in government settings — recruiting participants, designing careful experimental protocols, and generating publishable data.
A Prolific Research Output
Over the years, Honts's laboratory produced 79 publications [1]Verified Charles Honts — ResearchGate Profile
Confirms Honts's affiliation with Boise State University, Professor Emeritus status, 79 publications, education at University of Utah 1982–1986, and DoDPI affiliation 1988–1990 that collectively built one of the strongest bodies of empirical evidence in polygraph science, earning over 3,800 citations according to Google Scholar [4]Verified Charles Robert Honts — Google Scholar Profile
Confirms Honts has 3,863 citations and is Professor of Psychological Science at Boise State University. Beyond formal publications, Professor Honts has published and presented more than 350 scientific papers on deception detection [5]Verified Facts and Fiction About Truth and Deception — TEDxBoise
Confirms Honts has appeared as an expert witness 121 times, has published/presented 350+ scientific papers, and maintains a 36-year research program. He is now Professor Emeritus at the university [1]Verified Charles Honts — ResearchGate Profile
Confirms Honts's affiliation with Boise State University, Professor Emeritus status, 79 publications, education at University of Utah 1982–1986, and DoDPI affiliation 1988–1990 and continues to contribute to the field.
Honts also mentored graduate students who went on to careers in both academic research and polygraph practice. This training role was particularly important because the polygraph field has historically had relatively few researchers with strong academic credentials in experimental psychology. By producing trained researchers, Honts helped ensure the next generation of polygraph scientists would have the methodological skills necessary to meet evolving standards of scientific evidence, an effort paralleled by researchers like Raymond Nelson and Avital Ginton in other contexts.
Research Philosophy and Methodology
Honts's research philosophy was distinctive in several ways. First, he was committed to transparency about error rates — both false positive rates and false negative rates. While some polygraph proponents preferred to emphasize only overall accuracy figures, Honts recognized that understanding specific types of errors was essential for scientific credibility and practical application. As research on the art and science of forensic psychophysiology has shown, balancing scientific methodology with examiner skill remains central to the profession [10]Verified A Realistic Perspective of the Art and Science of Forensic Psychophysiology
Foundational research on the balance between evidence-based polygraph methodology and the role of examiner skill.
Second, he consistently used standardized procedures that could be replicated by other researchers. Honts typically used the Utah comparison question test protocol, which had been thoroughly documented. Third, Honts was unusual among polygraph researchers in his willingness to investigate potential weaknesses in polygraph testing. His countermeasure research was not designed to promote the polygraph but to honestly assess its limitations [6]Verified 3 Credibility Assessment Experts Appointed to Converus Advisory Board
Confirms Honts has testified as an expert witness more than 100 times, maintains a private consulting practice, and is regarded as an expert on interrogation and false confessions. This willingness to confront uncomfortable findings actually strengthened his credibility as a scientist and made his testimony more persuasive in court, where judges were wary of advocates presenting only favorable evidence.
Countermeasure Research: The Studies That Changed Everything
Why Countermeasures Matter
Polygraph countermeasures are deliberate techniques employed by examinees to manipulate their physiological responses during testing. If a deceptive individual can successfully suppress responses to relevant questions or artificially amplify responses to comparison questions, they may produce a physiological pattern scored as truthful. The possibility of countermeasure success represents one of the most serious theoretical and practical threats to polygraph validity.
Countermeasures generally fall into two categories: physical countermeasures (such as biting the tongue, pressing a toe against the floor, or contracting muscles to produce physiological arousal during comparison questions) and mental countermeasures (such as counting backward by 7 during comparison questions to generate cognitive load and corresponding physiological arousal) [8]Verified Mental and Physical Countermeasures Reduce the Accuracy of Polygraph Tests
Confirms the 1994 study with 120 subjects showing both physical and mental countermeasures enabled approximately 50% of trained subjects to defeat the polygraph. Before Honts's research, the polygraph community had largely dismissed countermeasures as either ineffective or easily detected. Critics argued they represented a fatal flaw in the entire polygraph enterprise. Neither position was based on substantial empirical evidence — until Honts conducted his landmark studies. Understanding how the four components of a polygraph examination — including the pneumograph, cardiosphygmograph, galvanometer, and activity sensor — can be leveraged to detect countermeasures became an essential part of examiner training.
The Landmark 1994 Study
Honts's most influential countermeasure study was published in the Journal of Applied Psychology in 1994, co-authored with David C. Raskin and John C. Kircher [8]Verified Mental and Physical Countermeasures Reduce the Accuracy of Polygraph Tests
Confirms the 1994 study with 120 subjects showing both physical and mental countermeasures enabled approximately 50% of trained subjects to defeat the polygraph. This experiment used 120 subjects recruited from the general community [8]Verified Mental and Physical Countermeasures Reduce the Accuracy of Polygraph Tests
Confirms the 1994 study with 120 subjects showing both physical and mental countermeasures enabled approximately 50% of trained subjects to defeat the polygraph. Twenty subjects were innocent, and of the 100 guilty subjects, 80 were trained in the use of either a physical countermeasure (biting the tongue or pressing the toes to the floor) or a mental countermeasure (counting backward by 7) to be applied while comparison questions were presented [8]Verified Mental and Physical Countermeasures Reduce the Accuracy of Polygraph Tests
Confirms the 1994 study with 120 subjects showing both physical and mental countermeasures enabled approximately 50% of trained subjects to defeat the polygraph.
The findings were significant: both mental and physical countermeasures were equally effective, with each enabling approximately 50% of trained guilty subjects to defeat the polygraph test [8]Verified Mental and Physical Countermeasures Reduce the Accuracy of Polygraph Tests
Confirms the 1994 study with 120 subjects showing both physical and mental countermeasures enabled approximately 50% of trained subjects to defeat the polygraph. The strongest countermeasure effects were observed in the cardiovascular measures [8]Verified Mental and Physical Countermeasures Reduce the Accuracy of Polygraph Tests
Confirms the 1994 study with 120 subjects showing both physical and mental countermeasures enabled approximately 50% of trained subjects to defeat the polygraph.

Confirms the 2003 National Research Council review of polygraph science, including citations to multiple Honts studies on countermeasures and CQT validity. In a 2001 study on spontaneous countermeasures, Honts and colleagues found that untrained countermeasure attempts had different effects than expert-coached efforts — trained countermeasures were far more dangerous to test validity [7]Verified The Polygraph and Lie Detection (NRC Report)
Confirms the 2003 National Research Council review of polygraph science, including citations to multiple Honts studies on countermeasures and CQT validity.
Implications for Practice and Policy
These findings had profound implications for polygraph practice and policy. For practitioners, they highlighted the importance of movement sensor pads, careful behavioral observation, and countermeasure-aware questioning strategies. Honts's work drove improvements in examiner training and encouraged organizations like the European Polygraph Association to strengthen their protocols for detecting countermeasures.
For the legal community, the countermeasure data offered the kind of transparent error rate information that the Daubert standard requires [9]Verified Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993)
Confirms the Supreme Court established the Daubert standard requiring judges to evaluate scientific validity, testability, peer review, error rates, and general acceptance. The research provided realistic assessments of what polygraph testing could and could not accomplish, making it easier for courts to weigh polygraph evidence appropriately. For polygraph examiners learning to handle difficult examinees, Honts's countermeasure research became essential reading, as the field of standardized polygraph terminology now reflects [16]Verified Terminology Reference for the Science of Psychophysiological Detection
Standardizes terminology across the polygraph profession, providing authoritative definitions with 94 scientific references.
Comparison Question Test (CQT) Validity Studies
Understanding the CQT Framework
The comparison question test has been the most widely used polygraph technique in criminal investigation and screening for decades [3]Verified A Comprehensive Meta-Analysis of the Comparison Question Polygraph Test
Confirms the 2021 meta-analysis coded 138 datasets, found effect size of 0.69, significant moderator effects, and that CQT decisions in the median sample were 86% correct. The CQT operates on the principle that deceptive individuals will show greater physiological arousal to relevant questions than to comparison questions, while truthful individuals show the opposite pattern [3]Verified A Comprehensive Meta-Analysis of the Comparison Question Polygraph Test
Confirms the 2021 meta-analysis coded 138 datasets, found effect size of 0.69, significant moderator effects, and that CQT decisions in the median sample were 86% correct. The theoretical criticism of the CQT centers on the comparison question mechanism: critics argue there is no guarantee that truthful subjects will respond more strongly to comparison questions, particularly when relevant questions concern serious allegations.
Honts addressed this criticism through carefully designed experiments. In a 2015 study published in Physiology & Behavior, Honts and Reavy conducted a mock crime experiment with 250 paid participants comparing probable-lie and directed-lie variants of the CQT [11]Verified The Comparison Question Polygraph Test: A Contrast of Methods and Scoring
Confirms Honts's 2015 study with 250 participants comparing probable-lie and directed-lie CQT variants, finding equivalent validity.

Navigating Daubert: Scientific Admissibility After 1993
The U.S. Supreme Court's 1993 decision in Daubert v. Merrell Dow Pharmaceuticals, Inc. fundamentally changed the landscape for scientific evidence in federal courts [9]Verified Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993)
Confirms the Supreme Court established the Daubert standard requiring judges to evaluate scientific validity, testability, peer review, error rates, and general acceptance. The Daubert standard replaced the older Frye "general acceptance" test with a more nuanced framework requiring judges to assess whether expert testimony was based on sufficient facts, reliable principles and methods, and the reliable application of those methods to the case [9]Verified Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993)
Confirms the Supreme Court established the Daubert standard requiring judges to evaluate scientific validity, testability, peer review, error rates, and general acceptance. Key Daubert factors include whether the theory can be tested, whether it has been subjected to peer review and publication, its known or potential error rate, and whether it is widely accepted in the relevant scientific community [9]Verified Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993)
Confirms the Supreme Court established the Daubert standard requiring judges to evaluate scientific validity, testability, peer review, error rates, and general acceptance.
Honts had co-authored the pivotal 1992 article in Law and Human Behavior with Mary V. Perry, titled "Polygraph Admissibility: Changes and Challenges" [12]Verified Polygraph Admissibility: Changes and Challenges
Confirms the 1992 Honts & Perry publication in Law and Human Behavior, Vol. 16, pp. 357-379, analyzing federal appellate decisions on polygraph admissibility, which analyzed federal appellate decisions on polygraph admissibility.

Confirms the 1992 Honts & Perry publication in Law and Human Behavior, Vol. 16, pp. 357-379, analyzing federal appellate decisions on polygraph admissibility — a transparency that enhanced its credibility.
As Honts noted in his analysis of the Frye decision, it "generally closed the door on the legal admissibility of polygraph tests in most jurisdictions for seventy years" [13]Verified The Polygraph in 1995: Progress in Science and the Law
Confirms Honts's analysis that the Frye decision closed the door on polygraph admissibility for seventy years, and reviews the state of polygraph science and law as of 1995. The Daubert decision, with its emphasis on testable hypotheses, known error rates, and peer-reviewed publications, created an opening for well-researched polygraph evidence that met higher scientific standards. Honts's career-long commitment to publishing in peer-reviewed journals, transparently reporting error rates, and using replicable methods positioned him and his research perfectly to meet Daubert's requirements. For comparison with how polygraph admissibility has evolved in other legal systems, different jurisdictions have adopted varying approaches.
Engaging the Critics: The Scientific Debate

His approach to credibility assessment research — with its emphasis on standardized procedures, computerized scoring, transparent error rates, and replicable methodology — set a standard that continues to guide the field. The co-edited 2014 volume Credibility Assessment: Scientific Research and Applications, produced with Raskin and Kircher, stands as a comprehensive reference for the field [3]Verified A Comprehensive Meta-Analysis of the Comparison Question Polygraph Test
Confirms the 2021 meta-analysis coded 138 datasets, found effect size of 0.69, significant moderator effects, and that CQT decisions in the median sample were 86% correct. Researchers like Joseph Kubis and Norman Ansley contributed foundational work in earlier eras; Honts carried that tradition into the modern scientific and legal landscape.
The field of polygraph science continues to evolve, with emerging technologies like neuroimaging-based deception detection and fMRI approaches being explored as potential alternatives or supplements. As courts continue to evaluate what scientific evidence meets the Daubert standard, Honts's body of work remains the gold standard for demonstrating how rigorous empirical research can support the admissibility of credibility assessment evidence.
Frequently Asked Questions
What is Charles Honts's most cited research finding?
Honts's most widely cited polygraph research is his 1994 study in the Journal of Applied Psychology showing that both physical and mental countermeasures enabled approximately 50% of trained guilty subjects to defeat the polygraph test [8]Verified Mental and Physical Countermeasures Reduce the Accuracy of Polygraph Tests
Confirms the 1994 study with 120 subjects showing both physical and mental countermeasures enabled approximately 50% of trained subjects to defeat the polygraph. This finding fundamentally changed how examiners approach countermeasure detection and is routinely cited in both scientific and legal literature.

What is the Daubert standard and how does it relate to Honts's work?
The Daubert standard, established by the U.S. Supreme Court in 1993, requires judges to evaluate whether expert testimony is based on testable theories, peer-reviewed publications, known error rates, and scientific acceptance [9]Verified Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993)
Confirms the Supreme Court established the Daubert standard requiring judges to evaluate scientific validity, testability, peer review, error rates, and general acceptance. Honts's career-long commitment to publishing in peer-reviewed journals, transparently reporting error rates, and using replicable methods made his polygraph research well-suited to meet these requirements.
Did Honts's research help or hurt the case for polygraph admissibility?
Honts's research ultimately strengthened the scientific case for polygraph admissibility. While his countermeasure findings revealed genuine vulnerabilities, his transparency about those limitations actually enhanced his credibility as a witness. His 2021 meta-analysis provided the strongest empirical evidence yet that the CQT produces accurate results, with decisions 86% correct in the median sample and information gain approximately 7 times better than unaided human judgment [3]Verified A Comprehensive Meta-Analysis of the Comparison Question Polygraph Test
