The Body Language Of Deception In Celebrity Traitors

The Celebrity Traitors (2025) revealed just how much body language gives away when someone is lying. The BBC hit format pits Faithfuls against Traitors, loyalty against deception, all set in a Scottish castle and hosted by Claudia Winkleman. With a cast of famous faces playing the game, every raised eyebrow and hesitant smile felt loaded for viewers trying to spot who was bluffing.

Many of the cast were friends off-screen, which added another layer of intrigue for both the players and the audience. When someone like Alan Carr or Jonathan Ross was accused of lying, the stakes felt personal.

Decoding The Celebrity Traitors' Body Language Of Deception

This is where Martin Brooks, author of Body Language Decoder, came in. In his video for The Standard, Martin analysed specific deception tells from two of the Traitors, subtle cues that the Faithfuls completely missed. His insights bridge TV and the real world: in both arenas, unnoticed deception can quietly cause chaos. As Martin explains, “we’re wired to assume honesty, even when the signs tell us otherwise.”

Martin Brooks' Six Deception Detection Tactics

1. Eye blocking. Liars often avoid eye contact by looking down, looking away, or blinking excessively to hide their eyes.
2. Truth slips. When body language contradicts words. For example, nodding “no” while saying “yes.”
3. Facial touching. A self-soothing behaviour. Liars may touch their face, head, or mouth to calm themselves when lying.
4. Duping delight. A fleeting smile or smirk that appears when a liar feels relieved or pleased their deception has been believed.
5. Forced eye contact. Overcompensating by holding too much eye contact in an attempt to seem honest.
6. Variance from baseline. Establish how someone behaves when telling the truth, then look for changes when they may be lying. (Kate Garraway did this with Cat Burns in episode one.)

These six cues, drawn from Martin’s Body Language Decoder, are tools anyone can use to spot deception, whether watching The Traitors or navigating everyday interactions.

Martin also noted that the Faithfuls’ failure to spot the Traitors’ deception mirrored real life. In business, the same thing happens: when subtle signs of dishonesty go unnoticed, poor decisions and bigger problems follow.

If you want your team to read these signals more effectively, Martin delivers a keynote on deception detection and trust building, available to book through PepTalk.

Frequently Asked Questions

What is deception detection using body language?

Deception detection looks at the gap between what someone says and what their body does at the same moment, cues like broken eye contact, facial touching, forced smiles, or a sudden shift from someone’s normal baseline behaviour. No single sign proves a lie, but a cluster of them, spotted in context, is a useful signal.

Can these Celebrity Traitors cues be used in business?

Yes. The same tells that gave away Traitors on screen show up in negotiations, interviews, and team meetings. Leaders who learn to read them make better calls on who to trust, and speakers like Martin Brooks translate the skill into practical, workplace-ready training.
