Ni is about scaling well, depth perception (in a temporal way too), and most of all conceptual or metaphoric BLENDING.
information in itself is new, or it is untenable and invisible and not information. it is not different, therefore it says nothing. always more difference, which gives more perspective and prospective relationships to absorb.
i agree very heartedly that the abstractedness of Ni is crucial to understand the difference between Ni and Si. there is some kind of strangely weird essentialism that is built into Ni, everything is immediately conceptual bc we are aware of the streets as patterns upon which everything is built. everything is contextualized and decontextualized and recontextualized so endlessly, that the world is always a blended brew and when it feels great its because we have the perfect balance of notes and can smell each of them. we know we hit he mark and everything is in tune and the overall perspective is made up of thousands of tiny and delicious and fragrant little ones. blah blah microcosmic, etc.
