The psychology of Ni/Se is less compartmentalized. Aspects within the Ni map will generally have a link to most any other aspect in the map, in some form or another. The points of literal data which Se brings into the map alter the tapestry of the map and bend/curve it into new shapes, giving rise to concepts that it had no direct exposure to but which emerged naturally from the causal direction the map was heading.
When Se is above Ni, the craving for sensory stimulation is great. Unlike Ne which fails to capture the complete richness of a tactile object, Se experiences the fine crevices, dips, edges, sparkles and nuances which are the very thing that they find fascinating. (Ne's fascination with an object revolves around how it can be manipulated and combined with other concepts.) The attention-span of Se can be strong if the object has a lot of richness to absorb, or very short if it doesn't.
For both Ne and Se, the interest in exploring something will persist so long as it has something unexplored. But for Ne, what is unexplored is the implications of how an object can be manipulated - and so long as it can think up novel ways to use the same basic object (uninteresting as it may be to Se) it will remain engaged. For Se, it's engagement will not be based on "how many things can you think up from this" but on the quality of the object itself. It will seek out richer environments and bask in the overwhelm of stimuli it gets naturally from the objects around it - as opposed to it's head's fabrications.
All the while, Ni stores these sensations and creates a map of associations they have both in time & placement. These associations have long-reaching effects, as the formulas that Ni extracts from those events are generalized and apply somewhat to all other aspects. Ni does not have many specific anchor-points nor does it speak referencing those particulars but instead explains things within the context of their whole paradigm and how it all relates to the rest.
Although there is a benefit in Ni/Se's map intuiting and compensating for missing data, the formulas it builds, when too general, create erroneous perspectives formed from connecting elements in certain ways that have no justification other than the direction their map bent to form them. While Ne/Si can be prone to irrational optimism and paranoia, Ni/Se can be prone to irrational superstitions. It may seems as though a certain event lead, causally, to another, when no tactile trace exists for the connection. When taken more extremely, it may also generate answers to realms where everything is unknown using nothing but patterns and symmetries.
This is the origin of the majority of esoteric & mythical constructs throughout history, when Ni is applied to the unknown realm of meta-physics. Concepts of symmetry, reciprocity natural-law and alignments are basic patterns which Ni sees and fills the unknowns with. For this reason strong Ni users can have a "mystical" sense about them and "knowing" aura of certainty about the questions that baffle the rest of us. It may not mean that they have any more knowledge of a realm than we do, but by the nature of their psychic process they formulate an answer to it where many others remain clueless or adapt a hypothesis of this sort.
