Memory Is Reconstructive: Why Recall Changes the Memory

Memory does not work like a recording. Every time you recall something, you rebuild it, and the rebuild is not identical to the original.

Reconstruction

Retrieval assembles a memory from partial traces plus schema-driven inference about what must have been the case. This is efficient - it lets you recall the gist of thousands of experiences without storing every detail - and it means the reconstruction can incorporate information that was not in the original. Reconsolidation research suggests that a retrieved memory becomes temporarily labile and is re-stored, potentially in altered form.

The false memory research

Laboratory work has repeatedly demonstrated that people can be led to recall events that did not occur. Misinformation introduced after an event can be incorporated into recall of the event itself. The Deese-Roediger-McDermott paradigm reliably produces confident recall of words that were never presented. These are not exotic effects requiring elaborate manipulation - they arise from the normal operation of a reconstructive system.

What follows from it

Confidence in a memory is a poor guide to its accuracy, and vivid detail is not evidence of accuracy either. Flashbulb memories of dramatic events feel exceptionally vivid and have been shown to change substantially over years while confidence remains high. Practical implications: write things down at the time if accuracy matters, be cautious about leading questions when asking others what happened, and hold your own certainty about disputed events a little more loosely.
