Negativity Bias: Why Your Brain Weighs Bad Heavier Than Good (ND2E18)


Listen Later

Bad sticks. Good slides off. You can name three things that went wrong this week faster than three that went right, and that asymmetry isn't a personality flaw or a bad mood. It's a measurable feature of how your brain processes information, and it's now being exploited at industrial scale by the feeds you scroll every day.


In this digest, you'll learn:

  • Roy Baumeister's 2001 review paper "Bad Is Stronger Than Good" and what it documents across relationships, learning, and social judgment
  • Kahneman and Tversky's loss aversion finding (losses hurt roughly twice as much as equivalent gains feel good)
  • John Gottman's five-to-one ratio in relationship research
  • Ito and Cacioppo's 1998 EEG work on the late positive potential and negative valence
  • Rozin and Royzman's four features of negativity bias: negative potency, steeper negative gradients, negative dominance, and negativity contagion
  • Joseph LeDoux's research on the amygdala's fast and slow threat-detection routes
  • Vaish, Grossmann, and Woodward's developmental evidence that the bias appears in infants
  • Robertson et al.'s 2023 Nature Human Behaviour study on negative words and headline click-through rates
  • Brady et al.'s 2017 research on moral-emotional language and social diffusion
  • A practical feed audit you can run this week in 10 minutes
