About Aldert Vrij
Aldert Vrij (born 1960) is a Professor of Applied Social Psychology in the Department of Psychology at the University of Portsmouth in England, where he has held this position since 2000. He earned his Ph.D. in 1991 from Vrije Universiteit in Amsterdam and came to the UK in 1994, when he joined the Psychology Department as a Senior Lecturer. His main research interest is deception, resulting in more than 600 publications and more than 30,000 citations.
His main area of expertise is utilizing nonverbal and verbal cues of deception, also called lie detection. Vrij has made critical contributions to understanding polygraph testing methods, including extensive analysis of the Comparison Question Test (CQT) and Concealed Information Test (CIT). His book Detecting Lies and Deceit: Pitfalls and Opportunities (published by Wiley) is a comprehensive overview of research into (non)verbal and physiological deception and lie detection. His meta-analytic work has examined both traditional physiological approaches to lie detection and newer cognitive load techniques for eliciting verbal cues to deceit. His work has found only a weak association between nonverbal behaviors and deception, leading him to advocate for evidence-based interviewing approaches over traditional arousal-based methods.
In 2016 he received the International Investigative Interviewing Research Group (iiiRG) Lifetime Achievement Award in recognition of his significant contribution to investigative interviewing. He is the editor of Legal and Criminological Psychology and serves on the editorial boards of several journals, including Law and Human Behavior, Human Communication Research, Applied Cognitive Psychology, and Journal of Investigative Psychology and Offender Profiling. He has received grants totalling over $11,500,000 from British Research Councils, the Federal Bureau of Investigation, and American, British, Dutch, and Singapore Governments, and works closely with practitioners (police, security services and insurers). His frequent collaborators include Ronald Fisher, Samantha Mann, Sharon Leal, and Pär Anders Granhag.
While Vrij's work spans the full spectrum of deception detection methods—from nonverbal behavior to neurophysiological techniques—his research on polygraph testing has been particularly influential in critically evaluating the scientific basis of these tools. His commentary on the protection of innocent suspects highlights fundamental concerns about false-positive errors in CQT polygraph testing, emphasizing that truth tellers may appear nervous or anxious during examinations. This cross-disciplinary approach, bridging psychology, law, and investigative practice, has shaped how practitioners and policymakers understand the capabilities and limitations of physiological lie detection.
