Combatitive Fi attitude comes first in everything she does. Clearly Se/Ni valuing in her music videos and lyrics.
“Bruises, on both my knees for you
Don’t say thank you or please
I do what I want when I'm wanting to
My soul? So cynical
So you're a tough guy
Like it really rough guy
Just can't get enough guy
Chest always so puffed guy
I'm that bad type
Make your mama sad type
Make your girlfriend mad tight
Might seduce your dad type
I'm the bad guy, duh”
Ne is not that straightforward and aggressive in its delivery. Has a goofy sense of humor in interviews which is not atypical of +Fe and Se subtype; being “quirky” does not = Ne. Very clearly introverted and IxFx:
You really know how to make me cry
When you gimme those ocean eyes
I've never fallen from quite this high
Falling into your ocean eyes
Those ocean eyes”
^This has ExI written ALL over it, I don’t see how it’s not obvious. She has stated herself that she hates smiling: not a 4D Fe type, I could never imagine 4D Fe claiming that even if their Fe isn’t valued. VI isn’t always the best way to type but her eyes hold a ton of Fi and Ni in them -> Fi base + valued Ni. They look as if they’re staring directly into your soul which is a distinctly Fi and Ni trait IMO. IEE’s eyes and overall body language gives the impression that they’re “everywhere” at once, soaking in every trace of mental excitement. Very childlike. Very bright. There is absolutely nothing childlike about her and she is very beyond her years -> Gamma. IEE and Se ego alike can wear bold clothing but her style is way too put together for an IEE IMO and:
"If I'm in a bad mood, or if I'm uncomfortable, it's probably what I'm wearing that's making me feel that way."
^This is the definition of base Fi, lol. Only they have this extreme of a connection to what makes their identity; yes so does creative Fi but this is almost over the top. Her physical presence is also quite strong in my eyes. I think the IEE typings are solely a case of viewing her -Fi and +Fe. 469 tritype as well which is far more common in ESI; when I think of IEE 4 I generally picture an IEE-Fi 478 Sx/So because those are truly the only kind that I’ve encountered. Think Harley Quinn: Billie’s personality is the opposite of that if anything, the only similarity is an appreciation of “darkness” or “edginess”.
Her style of dressing screams “go away” or “do not disturb me”, whereas an IEE has a much more open and warm feel.
Lastly, her temperament is extremely stable, to the point that I have also considered 9w8 as her core type and it’s definitely a major fix in her. IEE is the most obviously restless, scattered type in socionics from what I’ve gathered. They are constantly chasing butterflies so to speak. Billie comes off as grounded and sure of herself, and not inclined to fidget. Quite frankly, I think IEE is a shit typing for her.
