I conceptualize IEI, INFp as INFJ and EII as INFP.
The systems give specific ways the functions manifest not how they actually work which is more abstract and vague as the cognition
This is a really good video and I relate to both, of coures I disagree with him on some things but he is right while being wrong
He seems kinda wrong because I have seen other INFJs do INFP things as he says and INFPs being morally corrupt is actually Te not Fi thats why ESTJs are known as the morally right in the normie realm but INFPs are in the actual realm. "Victim mentality" is some bs that INFJs, ESTPs and ESTJ for example try to instill as a something that's real in an INFP. They punish someone for something they can't control that they pushed onto them and then punish them again for feeling bad/suffering as whiny victims. And a lot of INFPs suck that up and become "better". It is Fi vs Te genuinity (truth) vs being liked and do as everyone else (Te).
INFJs are not good at spotting bs by default and they hate not being liked by others too.
INFJs are stuck constantly trying to figure out everything's relation to everything in the present moment, trying to look past it, into it, into what is there but's not perceived by coscious state of mind. Abstraction to apply everywhre, relate everything to everything to see the pattern in it all continuously.
INFPs are segmented in multiple sequences that go in breadth a little bit and then converge what's relevant to relate it back to themselves each other while having awareness of what was previously thought. Cognitive leaps and stops. Same with LII as IEI is ILI.
