Memory is a reconstruction
Human episodic memory is not a recording. It is rebuilt at recall and can be systematically distorted.
Bartlett’s War of the Ghosts experiments (1932) showed that recall bends toward the rememberer’s schemas. Details drop out. Familiar ones are invented. The mind prefers a coherent tale to a faithful tape.
Elizabeth Loftus and others showed that leading questions and post-event information alter reports of what was seen. False memories of childhood events can be implanted in a minority of subjects. Confidence is a poor guide to accuracy.
This does not mean every memory is a lie. It means the legal, historical, and personal weight we place on vivid recollection needs a discount. The hippocampus and neocortex store traces; retrieval is an act of construction.
Caveats
- Laboratory distortion rates do not license dismissing all testimony.
- Some memories (highly rehearsed, motor, traumatic) are more stable than others — still not videotape.
