Investigative Interviews and Deception Detection Myths

Law enforcement should stop teaching body language as a test of truthfulness. My new article examines 3 pitfalls: mistaking discomfort for dishonesty, misplaced confidence, and biased questioning.3 Reasons Law Enforcement Should Stop Teaching Body Language as an Interviewing and Lie Detection Tool Read the full article, including research references: truthintelligence.com/stop-t…

Can you hear a lie? A 2026 study found that pitch, intonation and other vocal characteristics carried some information about deception—but the signals changed across people and situations. There was no universal vocal “lie signature.” Voice can provide clues. It should not be treated as proof. Source: Capra et al., 2026.

Why AI-Generated Interrogation Advice Needs Scrutiny

Federal Testing Reported “Sub-Par Performance” for EyeDetect The Defense Counterintelligence and Security Agency (DCSA) reported that an independent Oak Ridge National Laboratory evaluation of commercial ocular-motor deception testing produced “sub-par performance,” consistent with an earlier pilot evaluation. That is an important finding when assessing claims about EyeDetect and other ocular-motor deception-detection systems. DCSA subsequently funded additional testing, including research involving Texas A&M/ARLIS. What remains difficult to evaluate publicly are the underlying performance details: sample size, sensitivity, specificity, false-positive rates, ground-truth methodology, and the complete technical reports. Laboratory classification accuracy should not be treated as established real-world screening accuracy—particularly for employment, intelligence, law-enforcement, or national-security screening—without independent field validation.

How Close Ended Questions can affect the investigation “Did you witness the incident?” sounds straightforward, but it asks the person to decide whether their observations qualify them as a witness. Someone who answers “no” may still have heard an argument, noticed a vehicle leaving, or observed activity beforehand. If the investigator accepts that answer and moves on, potentially relevant information may never emerge. Starting with “Tell me what you were doing that evening” gives the person an opportunity to describe their experience before the investigator narrows the inquiry. Closed-ended questions serve a useful purpose: confirming specific facts, checking understanding, and resolving details. Their value depends on when and how they are used. After someone describes a vehicle leaving, “Were its headlights on?” can clarify a particular observation. Asking only narrow questions from the outset, however, can leave the investigator with answers to the questions they anticipated, while missing information they never thought to ask about. Allow the account to develop, then use focused questions to clarify it.
