Integrity and lie detection tests fall into multiple categories, including:

Polygraph: Measures physiological responses to assess truthfulness.

Psychological Stress Evaluator (PSE): Analyzes voice stress to detect deception.

Personal Security Inventory: A written assessment designed to evaluate honesty and attitudes toward theft or other misconduct.

Each of these tools can play a role in assessing trustworthiness, particularly in high-risk or sensitive positions, and are often part of pre-employment or internal investigation procedures (where legally permissible).
