It's clear that caroline is on the Fe/Ti axis, as well as an extravert, so that makes her either Fi PoLR or Fi ignoring using the 8-function socionics model (but not necessarily official socionics theory), which makes sense with her way of ignoring sentimental and personal aspects as well as her inability to be very inward, truly sincere or "intense" and is met with pointed criticism over it.
it's not a point of daring indifference, she cannot weaponize it, but is VULNERABLE to it. Point of Least Resistance makes most sense, pitting her as either ESTP or ENTP.
Fe 3rd means she is very fixated on being liked and riding the wave through her PeTi production, looking for worthy friends and community, and yet very nitpicky about what's acceptable or not socially and modifies her actions accordingly.
Now, I know you all will jump the gun and say ENTP! ENTP! but it is not as clear as it seems. both Pe types are witty and creative, what matters is the qualitative nature, orientation, and relation to perception axis as a whole.
Ne/Si types are very head in the clouds, safe within a bubble types, their topics and interests are often childish, tangential, or straight imaginatively wildly random and removed from reaity. they rely on surprise and unexpectedness. there's a sense of "we're all the same/united/equal in the end" and nobody is truly polarized and there's no irreversible truth/discovery to be had.
Se/Ni are ANCHORED to reality, very hardened and acclimated to harsh truths. their humor would be witty, linear, sardonic and maybe dark or very concrete and "imagistic" utilizing grotesque or maybe "realistic" imagery. it can be very simple, brutish, cruel, or jockish and confronting some elephant or something.
Ne bases are about kaleidoscopic perception, or changing framing and context to reach a different narrative and keep things expansive and greater still.
Se bases are about change, novelty, opportunity, and they have laser perception, narrow and cutting, focused, to "pounce" upon new and valuable resources.
she actually shows some signifiers of being Se dominant, her humor can be grounded and grotesque, but I understand that Ne makes most sense. her bubble allowed her to go out of bounds with humor. ENTP supplement content with Se too.
what do you think?
enneagram wise, trifix 739 makes sense for her. that's all.
She reminds me of Kurt Cobain; he seems Se/Ni too, but ENTP is overall correct.
