CATIRIFIC YOUTUBER

I think Se/Fi, i'm using the Catrific ❤ 50 FACTS ❤ video as reference.

Has Fi tension, Fi pained faces all throughout video, Te blunt head nods (4:56/6:40), Se/Ni eyes (pealed back, steadier than Ne/Si eyes), Te "bear" hands (5:20/6:15), Ni scowling, non-projecting voice, snippy speech. Her hands are less rigid though, I think, maybe some Fe warm pushes with the hand gestures (6:21). It's hard to ignore facial tension though, so nah. 

Her smile at the beginning of the Phil and Dan Do My Make Up: AmazingCatisNotOnFire Part 2 is similar to Keira Knightley's, but she pulls head forward. Here is a picture from CT Visual Reading document. She is Te subpolar, Fi support.


In that video I just linked, she also smiles at (2:54) in which she pull her head forward, she also has wide smiles, which are indicators of Fe. However, afterwards, it almost looks as if she has the underlying emotion that is kind of overflowing (or trying not to) that Te/Fi supposedly has. In other words, no Ti neutral face. But the situation is (I guess) funny, so it'd be perfectly reasonable to act that way (trying not to laugh). Pulls head in during smile (5:50). 



Conclusion: I have no idea what I'm talking about lol

(Edit: Can someone teach me how to make spoilers so I can hide the pictures, it just looks messy when they're not hidden.)

There was a topic about her but I can't find it. She was typed SeFi. Keira Kneightly is NiTe I think, they share the same functions but their overall presence are quite different.

Catrific and Keira Knightley are both SeFi's.

I don't agree with many of his typings. Erifrail has typed both as SeFi a while ago. Her smile does look like a PeFi's and Erifrail even used her as an example to show what a support Fi smile looks like. When PeFi's smile it doesn't always rise up into their eyes, it depends on how hard they laugh. But even when it happens the eyes still tend to remain as the main focus of their face.
There are different shades to each type so not all SeFi's will look or come across the same.
Her smile is also more snarling than an NiTe's.

Fi support:
"When they smile/snarl, the effect is less of a bulge by the nostrils and moreso a rise upward almost into the eyes. The accidental snarls of “disgust” may often rise up to just below the eyes, but their alert Pe eyes will retain their priority."

This is exactly what Keira (and Catrific) does:

Okay, I didn't know that you had read it. I don't think her laugh is forced, though.
Take a look at this and this video and pause at 0:56 (first video) and 0:17 (second video). Those are clear PeFi laughs. Her eyes also look more Se than Ni and her energy seems to be constantly increasing rather than receding.

As a PiTe myself, I know that it's a big misconception that we can't come across as "enthusiastic" or that we are "cold" all the time, but when typing Keira I solely do it based on visual cues and energy. And not every type has the same vibe. There are SeFi's who have more Te and Ni so of course they will have a different vibe compared to someone who is very Se and Fi heavy.
I still don't fully understand why you think she's an NiTe. Could you maybe explain further?
