Hypothetically, if you were asked to describe what garments a person was wearing when they crossed your path, would you be able to recall that? Or, would it be necessary that you were actively paying attention at that time in order to recall such information?

Yeah; it depends on the day. I'd say the recall is limited to my 140° of forward field of view, and really minor details get deleted, blurred or smeared.

I live in a major city, and pass literally, not figuratively thousands of people every day, so my memory is crammed full of ostensibly millions of people at this point. I don't remember all of their outfits, but I can visualize a memory of say, riding on the subway, and remember almost every person and where they were sitting, and a rough approximation of what they were wearing.

A more unusual outfit would be more memorable, for instance, I had a friend who got a well-paying job, we met up at a convention, and he wore a purple shirt with a mosaic pattern on it. That was in 2015, but I can remember his exact appearance, haircut, the day of, and the shirt because of how unusual and uncommon purple Oxford/business shirts are.

I want to say my memory accuracy is around 88% on aggregate, with the highest quality memories being 96% accurate. Every time I touch a memory, I risk modifying it, so I whiteglove everything, and make sure to not overwrite any information. This is especially hard when reading childhood data because it was literally encoded by a consciousness that was still learning the English language, for ex.

In other words, what I'm trying to say is, my memory is reliable up until there is a lot of crowding. Extremely rich scenes or thousands of people together simultaneously makes it a lot harder, and while the recall is there, up to 10% of the data might be lost.

That sounds like how I believed my memory worked, I used to think it was extraordinarily exact and I was some kind of savant.

But out of curiosity, I set up a test where I recorded a boardgame session with my friends. After we finished playing, we sat and wrote down our memories of that time with as much detail as possible, in a different room and with no input from others, and then watched the recording.

I was broadly correct in my recollections and able to correctly paraphrase others, but whenever I went into detail my recollections were incorrect more often than not.

Turns out, I was gifted at bullshitting myself, lol. My friends and I had a great time executing that little test, we laughed a lot and learned about each other.

Have you ever conducted a test on yourself like the one I conducted?

Yeah; I've run similar tests and my working memory is exactly average, which is where my belief that the ability to store long term memories permanently is available to everyone.

For extra long memory validations, I've got photographs, and I also leave "memory checkpoints" in the real world, like landmarks in the slipstream of time, or physical objects in vaults that I can reference.

They're important for the continuity of self, but also to have empirical anchors of "real" objects:
