I'm only speaking to functions
Try speaking to people. Sometimes it helps.
Another function has to come forth besides Ne or Fi. Russell's sensualistic nature tells me that Se factors in as an alternate dominant.
You don't need to be S to be Sensual. Stop being so literal! ENFPs are ridiculously sensual people.
Go meet some. Not everything about people can be learned from books.
Just the opposite, it's freeing JCF from its rigid beginnings with Jung who thought in terms of one dominant, one auxiliary, and one inferior per personality.
Compatible yes. As I said above, there's no contradiction. I wasn't denying his ENFP, I was adding to it.
My previous ENTP call turned out to be a mixture of ENFP and ESTP.
Or, you know...you could just be wrong.
This typology shit is amazing. Get it wrong, add another type, call it "dual types theory"! Still wrong? Add another. Now it's tri-types. Just fucking make it up as you go along! The possibilities are endless!
Does "Ne unfettered by introverted Judgement" mean he had poor judgment?
That's a more prosaic way of putting it.
Isn't that a trait of Perceptives anyway?
Um...no. It's a trait of Pe-doms who haven't developed their auxiliary to a healthy functioning level.
Fi does not fetter Ne, it informs Ne like a good angel sitting on his right shoulder whispering admonishments in his ear about his behavior.
Fi = Jiminy Cricket? No. You're thinking of Fe.
Fi does whatever feels right and harmonious with the spirit. It doesn't imbue 'magical goodness' in the way you imply. Fi is essentially about integrity and integrity is essentially just about being consistent. It's not about moralising. It usually makes people aware of their effects on others and highly empathetic (which tends to help them avoid harming others), but that's only when it's functioning in a healthy, conscious way.
Fi definitely doesn't stop people "partying". Brand doesn't think fucking around or taking drugs is "wrong" (those are Fe values which he has not internalised - or hadn't, at that time). He is consistent within his own value framework. He has standards, they're just the kind we might like to file under "Alternative":
“I couldn't possibly have sex with someone with such a slender grasp on grammar!â€
“Even as a junkie I stayed true [to vegetarianism] - 'I shall have heroin, but I shan't have a hamburger.' What a sexy little paradox.â€
“I like threesomes with two women, not because I'm a cynical sexual predator. Oh no! But because I'm a romantic. I'm looking for "The One." And I'll find her more quickly if I audition two at a time.â€
This last was brilliantly tongue-in-cheek, but can also be seen as a good example of a weak Fi rationalisation. An ExTP wouldn't bother to rationalise it. The act is its own reward and advertising it, a display of sexual prowess/dominance. No higher purpose need be invoked. Russell mocks himself but at the same time seeks to justify the potentially exploitative aspects of his behaviour.
It's a delusionary way of thinking, but one ENFPs can be susceptible to. They sometimes (mis)use Fi to rationalise "questionable" moral choices. And because the thinking function can be underdeveloped, the glaring inconsistencies are obscured from view. He probably genuinely does not see any conflict between being "a romantic" on a quest for a soulmate and fucking anything with a pulse (and an adequate command of English grammar) that crosses his path. Thus his behaviour retains a kind of logic and consistency that makes sense to him. Which is all Fi really cares about.
But what do you mean he doesn't lose energy? He certainly becomes more careful and thoughtful, the exact opposite of what he was. Let me put it differently then. He doesn't lose energy, he actually requires more energy while discussing a realm of ideas that is not in the public view because he doesn't normally or habitually put it out there for people to see. It requires much less use of energy discussing things he is more comfortable with putting out there for show.
He was being grilled, he didn't feel adequate rapport with the interviewer to talk comfortably about his personal values. This is very ENFP. They have a deeply private side which they don't show to just anyone, you have to gain their trust.
If he were any kind of T, he would have been aroused by the cut and thrust of debate and a bit of antagonism. He would have acquired new energy. Instead, what you saw was him defensively shrinking into himself a little bit, because someone was challenging his core values. NFs do not like that.
I just came across this old podcast which caused the furore I alluded to in my first post (and Paxman alluded to in the interview - where he blamed Brand for creating a more bureaucratic BBC - anathema to the ENFP, sneaky old Jeremy!)
It's bloody hilarious. Absolutely suicidal. What's really in evidence is how Russell defers to the Thinker of the duo. He allows himself to be made the clown repeatedly, the butt of the joke, and he doesn't really retaliate (other than the jibes about Ross's much higher salary, which just come off as envious and yet another deferral). This is a classic ENFP posture. Jonathan Ross is ENTP or possibly ESTP. He uses typical Thinking put-downs and oneupmanship. He gets carried away with humiliating Russ, in fact, and it is he who oversteps the line which leads to Brand's show being cancelled. I can't tell you how many times I've seen this dynamic play out. It's like ENFPs invite it or something. Even though they find it hurtful. Ross would never ordinarily be that careless, but he was determined to outshine the younger comic, which he does, and at considerable cost.
Ross on Russ: "You don't really write jokes, do you? You just sort of exist on a waft of whimsy. Whimsy, and looking like something Tim Burton threw out in an early sketch for the Corpse Bride."

Enjoy.
