Polygraph Glossary Technique

exploratory test

Definition

The exploratory test is a Zone Comparison Technique format designed for addressing multiple issues within a single test. It allows examiners to explore several relevant topics to identify which ones produce significant physiological responses, potentially guiding subsequent single-issue testing.

What Is an Exploratory Test?

The exploratory test is a Zone Comparison Technique format for addressing multiple issues in a single examination. Unlike focused single-issue tests concentrating all relevant questions on one topic, the exploratory test investigates several areas to identify which produce significant physiological responding.

When Used

Typically employed early in an investigation when the specific issue hasn't been narrowed — for example, exploring direct involvement, knowledge of who committed an act, and possession of stolen items. The exploratory test identifies which topics warrant focused follow-up, serving as a diagnostic triage tool for the investigation.

Relationship to Breakdown Testing

If significant responding is identified, the examiner conducts breakdown testing — focused single-issue tests on identified topics for diagnostic precision. The exploratory test serves a screening function; the breakdown test provides diagnostic specificity with DI/NDI classifications.

Accuracy Considerations

Multi-issue formats produce lower accuracy than single-issue because the psychological focus is distributed across topics. Results use SR/NSR screening terminology rather than diagnostic DI/NDI.
