Negativity Bias

Negativity Bias reveals that bad is psychologically stronger than good: our brains process negative stimuli more deeply and remember them more vividly, weighting them roughly five times more heavily in decision-making than equivalent positive stimuli, as shown in Baumeister et al.'s 2001 meta-analysis. This effect is more impactful than the Bandwagon Effect; while conformity amplifies group actions, negativity bias amplifies individual reactions to threats. It was evolutionarily adaptive when missing a predator was fatal, but today it manifests as one critical comment ruining a day of compliments or losses hurting twice as much as gains feel good—Kahneman's prospect theory confirms this 2:1 ratio. News outlets exploit this, with disaster stories receiving 40% more recall than positive ones.
