Abstract

The Integrated Zone Comparison Technique (IZCT) was utilized with computerized polygraph instrumentation as part of a blind study in the detection of deception. Three scoring algorithms: ASIT Poly Suite (Academy for Scientific Investigative Training's Horizontal Scoring and Algorithm for Chart Interpretation), PolyScore® 5.5, and the Objective Scoring System (OSS) were assessed in the interpretation of the charts generated. Where "Inconclusives" were excluded, accuracy for the IZCT with all three algorithms was 100%. When "Inconclusives" were counted as errors, overall accuracy for the IZCT with ASIT Poly Suite was 90% and accuracy with PolyScore and the Objective Scoring System was 72%.
