Interview and Interrogation Techniques:
The Truth About Body Language and Deception
If you were trained to “spot lies” by watching body language, this course explains why that approach fails — and how it leads to false assumptions, confirmation bias, and investigative error.
While nonverbal behavior can reflect stress, emotion, or cognitive load, it cannot reliably indicate truth or deception.
This course separates myth from evidence and shows how skilled interviewers prioritize verbal content, context, and interview structure over nonverbal folklore — producing analyses that are accurate, defensible, and courtroom-safe.
Why Body Language Alone Isn’t Enough
It’s easy to fall for nonverbal deception myths — they’re everywhere. But peer-reviewed research shows that trying to detect deception based solely on body language is only 54% accurate. That’s no better than flipping a coin.
In real-world interviews, relying on myths like eye aversion or fidgeting can lead to false assumptions, confirmation bias, and even wrongful accusations. That’s why this course is built on evidence — not folklore.
What You Will Learn
- Why most body language “rules” lead to false assumptions.
- What the science really says about deception and movement.
- Key nonverbal signals that support — not replace — verbal content.
- How context and baseline behavior shape interpretation.
- How to avoid the “junk science” trap in court or on the stand.
Why It Matters
Body language myths are everywhere — in pop culture, on YouTube, even in some police training rooms.
Relying on outdated or debunked cues doesn’t just weaken your case — it can destroy your credibility.
This course gives you the tools to separate science from speculation so your analysis holds up in the real world — and in court.

- Law enforcement professionals looking to update outdated training.
- Fire, arson, and fraud investigators who rely on nonverbal cues.
