Professional Review Tool

Polygraph Evidence Evaluator

ESS-to-Bayesian Translator for Professional Review. Document Empirical Scoring System inputs, selected likelihood ratio assumptions, and how the evidence shifts the prior probability.

Safety and ethics

This tool supports transparent evidence documentation. It does not determine deception, truthfulness, guilt, innocence, admissibility, or diagnostic certainty. Outputs depend on examiner-entered assumptions and selected likelihood ratios.

Legal and professional-use disclaimer

This tool is provided for qualified professional, research, educational, and documentation purposes only. It is not legal, clinical, investigative, or forensic advice and must not be used by unauthorised persons to make decisions about truthfulness, deception, guilt, innocence, suitability, risk, employment, relationship status, admissibility, or any legal right or obligation. Final decisions remain with appropriately qualified professionals.

4. ESS Evidence Weight Engine

Local JavaScript source tables generate provisional conservative documentation aids from ESS model, grand total score, and classification. These are not validated ESS normative likelihood ratios unless replaced with research-derived tables.

6. Bayesian Evidence Settings

Use Bayes factor and likelihood ratio terminology carefully. Enter the assumed evidential weight and select the direction it supports, or use the ESS engine suggestion with examiner review.
