Navigating Body Language Signs: Compass or GPS?
One wrong nonverbal read can send your interview off course. Body language may point investigators in a direction, but verbal content provides the clearer route. Learn why behavioral cues work more like a compass, while reliable verbal details work more like GPS.
When Interview Methods Are Challenged, Reliability Has to Answer
When interview methods are challenged, confidence is not enough. Reliability depends on whether the process can be explained, supported, documented, and defended. This article examines how questioning methods, contamination, agreement, and classroom-taught habits can follow an interview into reports, hearings, testimony, and courtroom scrutiny.
A Cluster of Bad Cues Is Still Just Bad Cues: Rethinking Stress, Deception, and Behavioral Clusters
Behavioral clusters are often treated as stronger than single cues, but grouping unreliable behaviors together does not make them reliable. This article examines the danger of mistaking stress for deception, the problem with cue stacking, and why investigators must protect the statement by testing information against facts rather than relying on behavioral assumptions.
Why Isn’t Interview and Interrogation Training Audited Like Use-of-Force Training?
Use-of-force training is routinely reviewed, updated, and defended against policy, law, and performance standards. Interview and interrogation training should face the same scrutiny. If outdated methods can contaminate statements, create false confidence, or increase courtroom risk, agencies need more than tradition. They need an audit trail for what is being taught and why.
Stress Is Not Deception: The Danger of Treating Behavior as Proof
Stress is not deception, and behavior is not proof. When investigators mistake ordinary stress, discomfort, or nervousness for deception, the interview can quickly shift from inquiry to confirmation bias. Observable behavior may help guide better questions, but it should never replace the work of testing the subject’s account for reliability, context, detail, and evidence.
The Eye Movement Myth
Eye movements have been repeatedly marketed as a shortcut to detecting deception, but the research does not support that claim. Looking up, down, left, or right does not reliably reveal whether a person is lying. Investigators need evidence-based questioning and statement analysis, not recycled myths dressed up as technique.
