I came to this forum to discuss personality types, and found there was an agenda preceding me. There has been a push against the MBTI and toward a return to cognitive functions.
I believe there are good, logical reasons to be against the MBTI, and I have stated those reasons here on many occasions - pretty much, every chance I get. But if I have any agenda, it is to use reason in solving problems. Compare reason to the whiny badgering of those who believe they have found the Answer in JCF.
Thinking you have found the Answer is not a problem for me. Everybody has their own answer. But that's just it - it's YOUR answer. I will debate with you logically over the validity of your answer. The fact that I only get one-liners and bigotry in return is evidence that your Answer is neither reasonable nor logical. So I often feel like a pet owner walking into a meeting of animal rights activists.
And really, your Answer is not reasonable. Jung was no scientist, he was some kind of modern "Prophet." Logic, as he employed it, was only a tool of some subconscious "reality." And so he created a religion or dogma of the subconscious that is not established in fact. Jung's logic is coherent enough, but it does not correspond to reality.
The main problem with Jung's theory is that he moved from cognitive functions
to personality types without regard to any scientific study whatsoever. Such a "Genius" as Jung apparently didn't need it, all of his Answers came from "somewhere" - God, taking the form of the collective unconsciousness, who has granted him omniscience by whispering into his subconscious "ear." The information came from some vast pool of collected wisdom hovering around somewhere in the aether, waiting for just the right kind of mind to extract the Truths lying therein. The result is merely a cultish following of those who don't dare question the Master.
But these intellectual fads tend to just come and go.
So far I haven't seen anybody who has spiritually profited from JCF. I've seen some dilettantish types hanging around who barely understand the words they are spouting into their keyboards. All I can say to you is that personality typing is not the same as cognitive function typing. And anyway, JCF is very reductionistic. I also know you don't know or care what that term means or what it implies about your rigid mindset.
Personality typing is about the whole character of the person, not these few cognitive functions you can barely manage to identify, if at all. For us, the clues to personality are always external to the person, not hidden in the secret recesses of their minds.
