For decades, investigators have been taught to spot deception by watching body language. Raised eyebrows. Crossed arms. Shifting posture.

The problem? It doesn’t work.

Despite decades of reinforcement, study after study shows that even trained professionals perform no better than chance when relying solely on nonverbal cues. The myth persists — in training academies, courtroom testimony, and pop culture — but it’s costing professionals their credibility, their cases, and sometimes their careers.

This course sets the record straight.

You’ll explore the truth behind widely taught deception “tells” and why they continue to mislead investigators and interviewers. We’ll dive into the science behind how humans communicate, why body language is often misunderstood, and what strategies actually work.
