“This is how memory works in the brain—as soon as you retrieve a memory, it becomes editable, just like a text document; it enters a vulnerable state and can get rewritten without your intent, consent, or knowledge. Often, a memory is rewritten by new information that gets colored in during one recollection, and then that new information gets grafted onto and stored with the old, all seamlessly, without your conscious awareness. This process can happen over and over again until the original memory in your brain has been replaced with subsequent interpretations, impressions, and recollections.”
