Your memory rewrites itself every time you remember

The more you recall something, the less accurate it gets.

Every time you remember something, you edit it. The original recording is gone — what you keep is the most recent re-saved version.

Neuroscientists call this *reconsolidation*. When a memory is recalled, the neural circuit holding it briefly destabilises, becomes plastic, and has to be written back into long-term storage. During that window, anything you are feeling, anything someone tells you, anything you happen to notice, can be folded into the trace before it locks again. The memory you store afterwards is a blend of the original and the moment of remembering.

This is why eyewitnesses grow more confident and less accurate over time. It is why a story told a hundred times drifts from the event it describes. The most-loved memories — the ones you revisit most — are the most heavily rewritten.

Your eyes decide what you hear

The film reel metaphor was always wrong. Memory is closer to a draft you revise every time you open it, never knowing which lines were in the first version.
