Validity and effectiveness of interrogation techniques: A meta-analytic review

Area of Science:

• Psychology
• Law Enforcement
• Intelligence Studies

Background:

• Human intelligence (HUMINT) gathering via interrogation has a long history.
• Psychological research has lagged in validating common interrogation methods.
• The Taxonomy of Interrogation Methods (ToIM) offers a framework for integrating approaches.

Purpose of the Study:

• To conduct a meta-analytic review of interrogation technique validity and effectiveness.
• To utilize the ToIM model as a foundation for evidence integration.
• To identify which interrogation techniques yield valuable and accurate information.

Main Methods:

• Systematic integration of evidence from 60 studies.
• Meta-analytic review focused on the Taxonomy of Interrogation Methods.
• Analysis of techniques across six domains of the ToIM.

Main Results:

• Rapport and Relationship Building, Presentation of Evidence, and Cognitive Facilitation were found to be valid.
• These effective techniques optimize both the amount and accuracy of gathered information.
• Evidence for the effectiveness of other interrogation domains was insufficient.

Conclusions:

• Positive relationships with subjects are crucial for effective information gathering.
• Rapport-building, evidence presentation, and cognitive facilitation are key interrogation strategies.
• Further research is needed to validate other interrogation techniques.
