Detecting Lies And Deceit by Aldert Vrij

The Psychology of Lying and the Implications for Professional Practice

Drawing on decades of psychological research and forensic case studies, this book examines how and why people lie, evaluates the reliability of commonly cited nonverbal and physiological cues, and presents evidence-based strategies for detecting deception in professional settings. It demonstrates that many popular beliefs—such as reading body language or microexpressions—are unreliable when used in isolation, and argues that verbal content, contextual information and interview techniques that increase cognitive load or exploit inconsistencies (for example, asking for reverse recounting or using unexpected questions and the strategic use of evidence) are more effective. The work also critiques tools like the polygraph, highlights methodological pitfalls in deception research, and offers practical guidance for investigators, clinicians and legal practitioners to improve accuracy and reduce errors.
