Emotion Amplifies Memory
The amygdala acts as an emotional alarm, signaling the hippocampus to prioritize emotionally significant events. Evolution wired us to remember threats and rewards, not routine — which is why a frightening moment sticks while last Tuesday's lunch fades.

That false sense of precision matters in court, where confident witnesses are not necessarily correct ones.
