In a way, I relate to the OP, in a way I'm completely the opposite.
The trick with trivia, is you need to expose yourself to it a lot before it'll sink in,
This is very true for me. If I'm exposed to something in depth and for a while, I might not know that I know it, but when it comes to recalling the details......it's quite sharp and on point.
Having inferior Si causes you to be less aware of sensory detail, Ne should be just as good at recalling information, it just does so by looking at patterns.
I can see the truth in this. I think it's my Ne rather than my Si that helps me remember the things that I do.
It's like everything is stored as an interconnected huge web (and the web expands and expands with each new moment lived), so if a trigger or a cue is given to me, that part of the web is activated, and there's a forcefulness to the clarity I feel when I know *I am right*. Of course, I get stuff wrong, but, I know in my gut when I'm sure of a piece of information's rightness and when I'm not that confident.
My memory is more "visual", as well. I can see it in my mind's eye, when I recall with a clarity, like the thing is just floating in front of me, apparent.
It's also likely that you need to be able to recall the whole picture before you can focus on the details at hand (see the forest before the trees, aka think globally). For example you might not remember that part in the movie until you can recall the rest of the movie. This way of gathering info doesn't pay off immediately, but when it does pay off, it should be quite useful
This.
What I am horrible at is remembering the technical terminologies for things, but, ask me to explain it, and I'll talk up a storm (the net helps in refreshing my memory because I know what it is, just not the name, so searching the web is an easy feat for me). I am also horrible at remembering, and recalling specific events, if the cues are 'vague'. E.g., how did you celebrate your 21st birthday? My ESFx best friend can recall it given just that question, while I am left stumped...but if she starts talking about a specific thing about that birthday....then, I'm transported back there, and I can recall. My past memories thus are hazy, and takes a very specific cue to recall, unless they were impactful in some grander, meaningful way. Also, my memory is not good with linear time unless some aspect of the details makes 'logical sense' timewise. I think this is the consequence of the stuff being stored as one huge interconnected jumble, rather than sequentially.
I can't recall dates for history related stuff, and am horrible at remembering birthdays. But, a piece of information about someone, something about their personal self, their identity, it somehow sticks with me, and well.
I think its the phenomenon of the Ne web, the associations has to be stimulated and not with some arbitrary trigger for that association, but, something that engages my Ti. The association has to make sense for it to be retrieved, hence why dates and other random trivial facts escape me, unless the cue has a "hint" embedded within it. And, the hint doesn't even have to be blatant, it can be subtle, obscure, as long as it's not trivial.
This, in a way, is a blessing in disguise. If someone tells me a detail about them (doesn't matter how small or inconsequential the detail is), somehow, I can tell if that detail is truthful or not, if I have a previous memory bank of them, and they had told me the opposite of that detail previously, or something about their personhood is contradictory to this new piece of information they're trying to feed me. It's like Ne-Ti blares off inside my head going......'wait, wait, wait....I can't store this information as I don't know where it goes in to connection within the web, there's a contradiction, we need to reshape the form of this web for this new piece of information to fit!' And, that's usually how I know if something is right or off, when my brain does a double-take and tells me that it's having trouble taking in that information. That's when I know that either my previous memory of it is wrong, or shoddy, or that the new piece of information is somehow an inconsistency. I call this my bullshit detector. (the flip side of this is that if I wanna fuck around with someone, and I'm telling tall tales to them, I am good at knowing if some random obscure thing I've told them in the past will point out the inconsistency of what I'm telling them now. I call this my bullshit maker.)
