Here’s a bullet-point summary of The Science of Lying (assuming you're referring to research on the psychology and neuroscience of lying):


🧠 The Science of Lying – Key Points Summary

  • Lying is a complex cognitive task
    → It involves working memory, inhibition, and planning—more mentally taxing than telling the truth.

  • Brain regions involved
    → Prefrontal cortex (decision-making), anterior cingulate cortex (conflict monitoring), and amygdala (emotional response) are all active during lying.

  • Types of lies
    White lies (to protect feelings), antisocial lies (for personal gain), and prosocial lies (for others’ benefit).

  • Developmental trajectory
    → Children start lying as early as age 2–3; lying ability improves with theory of mind and executive function development.

  • Physiological signs are unreliable
    → Increased heart rate, sweating, and eye movement are not consistent indicators—polygraphs are often inaccurate.

  • Liars vs. truth-tellers
    → Liars typically give less detailed, more structured responses and may take longer to respond.

  • Habitual liars' brains adapt
    → Studies show reduced amygdala response over time, suggesting emotional desensitization.

  • Social and cultural influence
    → Acceptability and frequency of lying vary across cultures and social contexts.

  • Truth bias
    → Humans are generally bad at detecting lies—only ~54% accurate—due to a natural tendency to trust.

  • Lie detection advances
    → Emerging tools include fMRI, EEG, and linguistic analysis, but ethical and practical limitations remain.
