Memory can indeed seem like a puzzle with many missing pieces. We rarely retrieve all the pieces, and our brains fill in the missing information with creative guesses, based on experience and pattern matching. This leads to many unfortunate misrecollections, often accompanied by the stubborn belief that we are recalling accurately. We cling to these misrememberings, storing them in our memory banks incorrectly, and then retrieving them in a still-incorrect form and with a stronger (misplaced) sense of certainty that they are accurate.
