#430 โ€“ Charan Ranganath: Human Memory, Imagination, Deja Vu, and False Memories

So we think it's tied to this basic, it's basically a byproduct of our mechanism of just learning, doing this error-driven learning as we go through life to become better and better and better to process things more and more efficiently.

Well, it doesn't happen all the time, but I think what may be happening is it's a partial match to something that we have, and it's not enough to trigger that sense of that ability to pull together all the pieces, but it's a close enough match to give you that intense sense of familiarity without the recollection of exactly what happened when.

#430 โ€“ Charan Ranganath: Human Memory, Imagination, Deja Vu, and False Memories

Well, I like to say there's no such thing as true or false memories, right? It's like Johnny Rotten from the Sex Pistols, he had a saying that's like, I don't believe in false memories any more than I believe in false songs, right? And so the basic idea is that we have these memories that reflect bits and pieces of what happened as well as our inferences and theories, right?

So I'm a scientist and I collect data, but I use theories to make sense of that data. And so a memory is kind of a mix of all these things.

So where memories can go off the deep end and become what we would call conventionally as false memories are sometimes little distortions where we filled in the blanks, the gaps in our memory based on things that we know but don't actually correspond to what happened, right? Mm-hmm.

So, if I were to tell you that I'm, like, you know, a story about this person who's, like, worried that they have cancer or something like that, and then, you know, they see a doctor and the doctor says, well, things are very much like you would have expected or, like, you know, what you were afraid of or something.

When people remember that, they'll often remember, well, the doctor told the patient that he had cancer, even if that wasn't in the story, because they're infusing meaning into that story, right? So that's a minor distortion.
