I like to summarize like this (though take this with a grain of salt as I'm not sure any of it is necessarily correct):
Ne Ni Divergent/outward orientation (extroverted function) Convergent/inward orientation (introverted function) Possibilities/potential Probabilities/prediction More open to simultaneously accepting multiple perspectives/
sometimes struggles to not see shades of gray
Prefer one correct/appropriate view/answer May be focused more on the question May be focused more on the answer
In picture form (was looking for inward and outward arrows to indicate divergence/convergence and thought this seemed rather congruent with my mental image of the two functions), Ne on the left, Ni on the right:
Additional thought: I find that Ne is the function I most often associate with the feeling of pure joy. Being handed a topic that generates lots of questions that generates lots of answers, especially when there's an absence of mutual exclusion in many of those answers, is akin to that feeling a child has waking up on Christmas morning—it's one of the most exciting and fun toys I can think of. Not sure if that's a thing unique to Ne or has something to do with its position in my particular functional stack (brainstorming impractical possibilities irritates the heck out of my ISFJ mother for sure!).
