So I've narrowed my type down to LSI or ESI, now that my understanding of socionics is less terrible.
I've realized threads on Ne polr here and elsewhere are pants. Most descriptions imply a dislike of breaking from routine and trying and understanding new things, and this is missing the point. Se types seek to understand the world as it objectively is, whereas Ne is concerned with understanding the world as it implicitly is, so curiosity and openness isn't a factor.
My way of describing Ne polr is like this; I see, and imagine reality as a series of static events. I can create rules based on information I know to decide how things are going to change and develop in the future, and these rules over time become increasingly complex (probably Ti, but this could be normative understanding for esi too). This is how my "Ni" manifests.
Ne seems completely alien to me, because I see reality as it objectively is, I can only determine what it could be through my system of rules. I think about the potentiality of something in a reactionary way, because of necessity.
When somebody is talking about a future event that they're excited about, I imagine the event as a static image(s) of whatever i associate with that event from experience, along with objective information about what I know about that event, and therefore from that rules as to how the event could develop.
It's boring and tedious for me to think about this kind of thing, so it's hard for me to be very enthusiastic. My ex used to get upset with me for playing down stuff she was excited about, which I didn't have a clue I was doing. I think it's this lack of enthusiasm for how things could potentially be that is interpreted as close mindedness.
Ne polr does not mean an aversion to trying and understanding new things, it's just a lack of ability to see the potentiality of something in a spontaneous and immediate way, and not valuing this either. And getting annoyed at people that do, but trying to hide it because i'm only jelly.
