How to spot a liar in SECONDS… | Body Language Expert Vanessa Van Edwards

Key Concepts:

• Lie detection accuracy
• Statistical cues to deceit
• Question inflection
• Volume drop
• Incongruencies (verbal/non-verbal)
• Disgust as a non-verbal cue

1. Lie Detection Accuracy and the Importance of Doubt:

• The average person's accuracy in spotting lies is only 54%, barely better than chance.
• Overestimating one's ability to detect lies is a common mistake.
• It's crucial to give people the benefit of the doubt due to the difficulty in accurately detecting deception.

2. Statistical Cues to Deceit (Vocal):

• Question Inflection: Using a question inflection on a statement, number, boundary, or timeline is suspicious.
  • Example: Saying "The budget was 500,000?" instead of stating it.
  • Actionable Insight: "Double click" on such statements to ensure clarity and confidence.
• Volume Drop: A sudden decrease in volume can indicate nervousness or anxiety.
  • Example: A salesperson losing volume when discussing a specific part of their presentation.
  • Actionable Insight: Investigate the area where the volume drop occurs with targeted questions.

3. Statistical Cues to Deceit (Non-Verbal):

• Incongruencies: Mismatches between verbal and non-verbal cues.
  • Example: Saying "yes" while shaking the head "no."
  • Cultural Note: Incongruent nods have different meanings in India, Bulgaria, and Pakistan.
• Disgust: Displaying disgust, even subconsciously, can indicate discomfort or dislike.
  • Physical Manifestations: Wrinkling the nose, flashing the upper whites of the teeth, sniffing.
  • Explanation: Liars may feel disgusted with themselves for lying.
  • Actionable Insight: Watch for subtle signs of disgust when presenting ideas or proposals.

4. Disgust as a Non-Verbal Cue - Detailed Explanation:

• Disgust is often displayed subconsciously when someone dislikes something.
• The nasal cavities tend to close when feeling disgusted, leading to a scrunching of the nose.
• Example: Reacting with a subtle "uh" or a sniff when presented with a proposal.
• Actionable Insight: If you see disgust, double-click and ask questions to understand the person's true feelings.

5. Real-World Application: Investor Questions:

• If an entrepreneur loses volume when discussing their co-founders, an investor should ask questions about the co-founders' relationship, how they communicate, and how they handle conflicts.

6. Synthesis/Conclusion:

While accurately detecting lies is challenging, certain statistical cues can provide valuable insights. These cues include question inflection, volume drops, incongruencies between verbal and non-verbal communication, and displays of disgust. These cues are not definitive proof of lying but rather red flags that warrant further investigation and questioning. By paying attention to these cues, one can improve their ability to understand others' true feelings and intentions.
