A FIELD VALIDATION STUDY OF THE QUADRI-ZONE COMPARISON TECHNIQUE by James Allan Matte and Ronald M. Reuss ABSTRACT:    This field study tested and demonstrated the validity and reliability of the Polygraph Quadri-Zone Comparison Technique designed for Specific-Issue tests, using one hundred and twenty-two confirmed real-life cases from a Metropolitan Police Department and a Private Polygraph firm. The Quadri-Zone’s unique Fourth Zone accurately identifies and remedies the major cause (Fear/Hope of Error) of false Positive/Negatives and Inconclusives in Specific-Issue tests. The Quadri-Zone Comparison Technique correctly identified 91% of the Innocent as Truthful and 9% as Inconclusive, with no errors. It further correctly identified 97% of the Guilty as Deceptive and 3% as Inconclusive, with no errors. Inconclusives excluded, the Quadri-Zone Comparison Technique was 100% accurate in the identification of the Innocent and the Guilty. Inconclusives included, the utility rate was 94%. Blind Scoring of polygraph charts showed extremely high correlations for the individual and total chart scores with no errors.    The complete study can be found in Volume 18, Number 4, 1989, of Polygraph, official journal of the American Polygraph Association. www.polygraph.org
