What if everyone has Ni? Ne is related to imagination, but not as strongly and perfectly "fitting" as Ni is. Imagination is about forming a perspective on something...and that really is Ni. Ne is more like "connection"...er I was thinking "Invention" and "Innovation"...I don't think there's neat and precise word out there that describes it.
I don't know though. I use my imagination to debunk perspectives, and by doing so, to try and hone in on a truth. My imagination is like the snake eating itself, constantly questioning what it produces and then re-imagining it differently. It feeds off itself and can cause me to tune out reality or end up daydreaming and neglect my health. What it produces isn't so much a perspective as it is a warehouse of intuitions that I can play with and use, hopefully to get a fuller picture of the world and everyone in it. But I'm not looking to 'order' the world, but have an 'understanding' of it.
My intuition tells me everything is relative and kind of disallows actually having a perspective. The only times I really do have a perspective is if I use 'logic' because that can be followed and understood without relative interpretations and definitions. But I only believe the logic, insomuch as it is applicable to reality. For instance, in the US government, higher taxes were placed on the rich, starting this year. And reports are claiming that it isn't hurting the economy. If that's true, then something else is going on economically that doesn't follow from logic and my logical perspective becomes no more.
Ooo, sounds like fun. How does it work?
War's over.

I'm not good at instigating. I was hoping you would.
Ne is perceiving information outwardly in an abstract fashion, used by INTPs to facilitate Ti, right?
Ni is perceiving information inwardly in an abstract fashion, used by ENTJs to facilitate Te.
Which one really sounds like it fosters imagination?
This is, more or less true; although Ne isn't limited to perceiving information outwardly as it is extroverted and will also create/impose new potentials for reality. ENTPs are often called "Inventors". ENFPs called the "Inspirers" (I'm assuming this is pretty much to mean they invent ways motivate people).
"Forming a perspective" isn't accomplished without the use of T. Ni is just "making connections" inwardly and is coupled best with Te to present the connections to the world in an objective fashion.
Right, but Ti forms perspectives too. This isn't limited to NiTe. The fact that Te is extroverted does mean that any perspective is changing with the current logical circumstances.
Ti being introverted on the other hand, tends to create its own universals, even if there is not much evidence for them and if there is no way to prove them absolutely.
What sounds more like "having a perspective" here?
Imagination (defined by Wikipedia) is the ability to form new images and sensations that are not perceived through sight, hearing, or other senses.
Sounds like intuition, sure.
Agreed.
Elaborating, Wikipedia also says "it is a whole cycle of image formation or any sensation which may be described as "hidden" as it takes place without anyone else's knowledge." Ohh sounds more like Ni to me.
Well, anything that takes place without anyone else's knowledge is related to introversion, sure. I don't know what "it is a whole cycle of image formation or any sensation" is supposed to mean exactly though. I imagine all introverts deal with such things or they wouldn't be introverted. The question to me is "What kinds of images does each introvert play with?"
I think INTP imagination is slightly different, and probably skips over the auxiliary function most of the time. It's probably more like Ti/Si. Innovation/invention on the other hand, these deal directly with the outside world, absolutely requiring perception of external data. This is where Ne could step in and outshine Te, because Ne is powered by introspection (Ti-Si) while Te is powered by imagination (Ni-Fi).
You make it sound like Ni is simply imagining the world as they want to. It's not that simple. Introspection is introversion, whether you want to believe that or not.
Sorry, I wanted to take the side of INTP, but after compiling this wikidata, I have to side with Words. *this is part of how war works. now you have an ally.
War!
