Recommended Polygraph & Lie Detection Books

The difference between a competent examiner and an exceptional one often comes down to depth of knowledge. Polygraph science has evolved dramatically since Larson's first instrument in 1921 — from analog chart analysis to computerized scoring algorithms, from Control Question Tests to the validated Concealed Information Test. The examiners who stay current with published research, understand the limitations of their tools, and can articulate the science behind their conclusions are the ones courts trust, attorneys respect, and clients rely on.

This library covers the full spectrum: foundational textbooks used in APA-accredited training programs, peer-reviewed scientific assessments of polygraph validity, deception science beyond the instrument, behavioral analysis and interviewing methodology, plus critical perspectives that every well-rounded examiner should know. Whether you're a student entering the field, a practicing examiner deepening your expertise, an attorney preparing for a case involving polygraph evidence, or a researcher studying credibility assessment — we've identified the essential reading for your path.
