Thanks for sharing, @scientiam and @faeruss!
As argued here, Big Five correlations between Ne&Se/Ni&Si/Ti&Fi/Te&Fe traits imply that they're indeed less independent as CT generally assumes. Moreover, quadrants also map on to John Verveake's four layers of consciousness: Participatory~Pe, Perspectival~Pi, Procedural~Ji, and Propositional~Je.

@faeruss You confused perspectival ('salience landscape') and participatory knowing ('what it is like'), btw. Did you watch Verveake's new course on meaning? For you don't seem to refer it in your last speculative thread.
Given the lack of engagement last time, and that Verveake had already been mentioned, I kept postponing to write an article on these layers. Yet Ji as procedural knowing adds an outside view to @auburn's insider perspective (which is already great!).
My Si seems to clear up; so, I hope to appear less speculative soon (and until then, please steelman my attempts...)

@sander Thank you for your feedback. Yes, indeed, I have seen Vervaeke's latest Meaning Crises videos. I don't think I have confused the two, perhaps I can explain how I saw it: perspectival concerns yes as you say relevance realisation, but more conceptually it concerns knowing what it is like from a certain vantage point. This gets tricky and somewhat intertwined with participatory knowing, were we know by sharing a fundamental identity with, by partaking in the life of something. So, we know what it is like to be wise in the participatory sense by becoming wise. We know what it is like to see the world as wise man, in the perspectival sense, by adopting the perspective of the wise one. These two process are arguably interlinked and reinforce each other.
 

@septimus-chalier Thanks, Septimus. I was drinking a bit of whisky indeed.

I like FeNi so much better for you @faeruss !  Vultology aside (yours is difficult) - I did feel after knowing you a little while that TiSe wasn't right for your personality.  We had all been arguing between NiFe and TiSe, but this new typing fits perfectly.

I have some time today, so I'm giving it more of a listen.
I tend to relate to approaching an object the same way Scientiam does. I'd like to arrange the structure myself to make it meaningful and weed out the inconsistencies. I very much relate to what Jung said about interpreting paintings on the cave wall. Nobody but the artist did the work, so to the others, they are just circles and lines. I'm paraphrasing. But there remains a sense to me that I must create from the ground up to test the veracity of a thing. It has to resonant from the inside. This may be a conductor/revisor difference. Conductors pick things up as tools, employ them, and discard or modify them if don't work well. Revisors seem to hold the tool, turn it, inspect it. We could even say they - as artisans - craft the tool.
(OMG, I love when Faeruss brings out the sword gesture to indicate Pi splitting off!)

"Is it true social interaction videos will bring out the extraverted functions and the solitary videos will bring out the introverted functions?"
 
In my experience being in a more extroverted environment (lots of people, a party, or situations with lots of talking and interacting) usually makes me more quiet as I cannot "fight" the other extroverted energy in the room. I may try but if no one is listening to me then I just get quiet and start observing.
If I am with one other close friend or intimates on the other hand or just alone in front of the camera, I can be more myself and more expressive. Still if people don't respond to my extroverted energy (laughing or interest) I will just start observing and taking in information from around me.
I can be life of the party but I have to be pretty stressed out and without an outside stimulus to calm me down or just really happy or excited about something.
 
long story short. for me it seems introverted activities bring about extroversion and extroverted ones bring about a more introverted persona.
 
this argument/proposition subject to change upon the users further experience with these things.

@courtjester im not sure if im right or wrong. Im simply stating what applies to me personally.
But yeah
that could change at any moment as life is constantly blessing and messing with us
