js grasp the world thru singularity. they see the one map that shows the information relevant to the question as an overarching, generalized abstraction (njs).
ps see the world thru the lens of difference. rather than being formed out of identity, seeing something as generalizable and the same (enough) as something else, they focus on particularity. meaning is based on possibilities moving forward (nps), the difference between possibilities constitues the meaning of the move. ps are multi-threaded, they can keep open more possibilities, and backtrack a few (inps vs enps sway the balance between some backtracking and ALL forward). it's like you scan the possibliities, and move in a direction, and then from that moment you kind of merge with the moment and scan for new possibilities.
js need to see the end goal in sight. they need to have a sense of direction that is not so in the moment. or access to the overmap to know why they are doing what they are doing. a generalized over-arching center/gravitational force to hold their actions together (whereas ps make decisions based on their own inner compass, based on particularity, in the moment instead, trusting their Ji). being in the moment is stressful for me, if i have to be and am not prepared. my enp friends, contrasting, hate not being in the moment enough to really explore possibilities. the sense of "we must go this direction" is limiting bc they don't get a chance to really explore, check out options, keep things open-ended, etc.
i see it as multiplicity (p) vs singularity (j). i need to see the way in which to see everything, the BLENDED best vantage point. i'm thinking js blend into one map, and ps maintain that difference is what makes the disparate forms of information relevant to them, keeping open access to a wide variety of mini-maps/simulations based on individual, particular possibilities.
(this is probably a dominant perceiver Ni-Ne bias, because for other types their judgment function could be a higher priority than perceiving in their overall make-up, or because they could be Si-Se and i really don't understand those very well yet).
