i don't think of isfps as "insane micromanagers." i don't see a natural connection between wes anderson and ernest hemingway, nor do i think of wes anderson as the "rugged outdoor" type. that seems ludicrous. but i will agree that his visual detail, the "bric a brac" criticism, and the inserts for his films do seem more Se than Ne. i would be interested to know more about what the writing process looks like for him. when he speaks he seems somewhat disjointed, but the 4w3 sophistication still comes through.
i don't think i misunderstand S. i think, if anything, it is difficult to interpret and expect in an exacting way the balance of S-N perception in various types, especially when they are developed differently in different enneagram types. yet tertiary Ni is not dominant Ni, just like inferior Se is not auxilary Se. the role they play is so different, because they contribute to such a different organism.
there is a tendency to associate quirky with N. this is bc N frees you from seeing a problem or an action in the same way, a concrete as-it-is kind of way. imaginative perception opens up possibilities, but also loses focuses and is generally less aware of implementation details on a zoomed in kind of way. it abstracts to think across time, over different distances and scopes.
wes, on the contrary, does seem to have what works for him and is gonna stick to it.
his world does have the feel it does based on the composition of the shot, the visual detail, and the visual details of the characters. plus music. the dialogue makes it sound 4w3, very much classic playwright wit/banter/absurdity. it's definitely very down to earth and not conceptual. i think i'm convinced.
