Why remember bad events more than good?

Answer: Negativity bias for survival

Negativity bias for survival ✓ — Correct! Our ancestors who remembered dangers (where predators hide, which foods are poisonous) survived better than those who forgot. The amygdala, our brain's threat-detection center, encodes negative experiences more strongly, making them stick in memory. One bad experience could mean death, while missing one good opportunity rarely did. Psychologists call this 'negativity bias.'

Good memories fade faster — Wrong. It's not that positive memories decay faster - both types decay similarly over time. The difference is in initial encoding strength: negative events trigger stronger emotional arousal and amygdala activation, creating deeper memory traces from the start.

Bad events damage memory storage — Wrong. Bad events don't damage memory storage—they actually strengthen memory formation. The amygdala encodes threatening information more strongly as a survival mechanism, making bad memories more vivid and persistent.
