Ygolo - when I say 'Ne types' I mean generally types that have Ne as their primary or secondary function
As for social sciences, I find the scope is just so wide that as a subject it can only make sense approached from an interdisciplinary perspective, like social science is the hub of a wheel whose spokes are say, history, languages/linguistics, mythology, psychology, medical science, religious/spiritual studies, demographics, etc., constantly cross-referenced.
My way of doing things, of say answering or figuring out the answer to a question (any question I guess, on any subject) is to first of all take a big step back to look at the whole thing from as wide an angle as possible, and that way I identify which parts might need zooming in on, and which other parts to cross-reference them with. That way I find myself getting to the nub of things much quicker than if I'd begun by only what appeared to be 'the topic', blindly groping outwards and barking up many wrong trees in the hopes of finding something.
