Rant about human memory

I feel that one of the main flaws about human memory is that one’s memory is basically reflective of one’s own personality, something that evolves overtime.
Your memory, unless it hasn’t been trained, only really remembers incidents that resonant with you or carries some significance to your own personality. Hence, I think people can easily miss out certain details of things because of their own personality, which I think is also something that not many people are aware of too.
For example, a child would not really have a fully developed personality, so is likely not able to recognize many of the horrors of the world, or typically just blocks it out. I mean the horrors of the world are basically saturated everywhere and yet children do not tend to notice them. Or a child would not be able to recognize many subtle manipulative behaviours. It’s all reflective of the child and not the way the world works. The world is inherently objective, whereas human experience is subjective.
In fact, I feel like the Chinese Whispers game is usually played with children because it demonstrates that information tends to degenerate as it passes through more people, the information changes depending on who hears it, which is dependent upon their personality. At the of the cycle, the initial information would have become fundamentally changed.
Also, the Chinese whispers game is something that I think children would tend to just go along with. It is something that they mainly do because it is fun and would not be consciously aware of the abstract notion of information degeneration. I feel as though children would be shocked that the message changes somewhat and would try and infer down the line as to why the information changes, or just sort of seize in terror.
But, then there’s the problem of trying to derive an objective viewpoint of the world. An objective viewpoint can not be fundamentally obtained through human experience. Human beings can not think objectively. They can be trained to think about certain things objectively, but how a person fundamentally interacts with something and perceives something is subjective.
I feel like human beings to an extent sort of perceive how other people interact basically in accordance to their own mood or feelings about a certain subject. Like, I’ve really noticed that when interacting with elderly people for instance. We either see them as old bigots can’t get with the times, or we see them as something to admire, because they’ve been through a lot and have this special knowledge, wisdom and insight that is only fundamentally obtained from an old person.
I feel like people also have a certain degree of para-social awareness of status, class and age etc. Like we perceive what a person with a certain degree of traits has, and we sort of infer that in our heads. It’s kind of weird, but I feel like basically anyone in the world has at least some semblance of an idea of what it’s like to be a child, teenager or to grow old etc. I can sort of perceive growing old in a certain sense, but I truly don’t know what it is like to become old because I am not old, I am 19 years old.
Part of the reason why I think this affects perception is that say you have an event that only a certain group of people have experienced. Only they have experienced it, and the stories of what they have experience, fundamentally, come from them. The stories are then told by other people, that is people who have not had these set of experiences, and get spread about, and the collective unconscious of people, through abstract processes, ultimately decide what is the true version of the story, or the story that is told throughout. (Fuck that got way too philosophical).
So anyhow, I feel like one of the fundamental problems with the following gedankenexperiment is that the group of people that have had these experiences would grow old and the story in their heads would change, leaving basically only the portions of the story that their personality will accept as being true. So, the information degeneration would still fundamentally happen. It really is not dependent on any group of people, even the people who have fundamentally had these experiences.
In fact, I basically can not remember exactly what I did in high school for instance (which for the record was from 2011-2017). I can remember remnants of what happened, and basically my version of the stories that happened during my time there, but I will never truly no with 100% certainty exactly everything I did there.
In fact, I feel as though the nostalgia of the time is fundamentally affected by my current mood, like for example with anxiety I would essentially remember all the bad and negative stuff that happened there, and when I’m calm or happy (hopefully fucking wouldn’t think of high school, but you know) I would think about all the good stuff that happened there, essentially my friends etc.
