Episode notes
Universal Truth Testing
- The brain processes truth testing similarly across domains like math, ethics, and personal beliefs.
- This suggests a single mode of representing reality, regardless of the specific content.
Lie Detector Flaws
- Traditional lie detectors are invalid because they track anxiety, not deception.
- They produce false positives and negatives, making them unreliable for important decisions.
Micro-expressions and Technology
- Micro-expressions are interesting but not consistently reliable for lie detection.
- Technology like fMRI and facial recognition software may offer more accurate lie detection in the future.
