Eli5: What makes human memory unreliable?
gpt
Human memory is synthesized when first formed; you sometimes create it even before you’ve processed all the sensory input you attach to it.  And then to keep a memory stored, you re-play it and store the result.  So each time you remember a memory, you have a chance of corrupting it with new false information.
