Regardless of what sources you found on the topic, with a single google search. Your statement of INTJ's paradoxitype, IS ESFP, IS FALSE. The S & N functions DO NOT FLIP. Still taking notes? I love how you are trying to pick apart what I'm saying while still missing the point. ESFP is not the paradoxitype of the INTJ. A statement you made, a statement that was false. Diving into details with you is pointless because you made a false statement to begin with, I simply pointed it out, and now you are grasping for straws and arguing because I rubbed your ego the wrong way. That's what you said, that's how I responded.
ISTJ and ENFP have opposite letters. But the letters are only a symbol for what is underneath, the functions + information. AN ISTJ and ENFP are actually much more similar to each other when it comes to FUNCTIONS then a bunch of other combination. BUT they do no they are not even close in terms of how they view the world and what they want out of the world. They are IJ vs EP. The order is different etc... I took a specific perspective on the issue, that perspective can be viewed in different ways. Your statement is simply FALSE by definition. Furthermore, an ENFP would NEVER WANT to be an ISTJ. In fact its probably what we desire the least. In contrast and ENFP really does love a lot of the strengths of an INTJ. The entire PURPOSE and INTENT of my statement to begin with.
ISTJ are very different from ENFP's for example more because of the order of the functions and less because of the strength or dominance of each function, because we still have the same 4 dominant functions. Si, Te, Fi, Ne for ISTJ and Ne, Fi, Te, Si for ENFP's. If you want to go truly opposite the 1st 4 functions would be completely different which would be an ESTP and ENFP combination. Even then though we still share the E and P and so similarities will exist with that as well. You can't exclude function or information when you analyze these things. ESTP & ENFP's for example focus on Observation of PEOPLE first.
PRADOXITYPE HOWEVER, would be an ENFP for an INTJ and vice-versa. That is not up for debate.
Lol clearly don't understand much about MBTI.
Oh and the site you are calling baseless. Is probably the single best source for MBTI information on the web today. Get a clue, ya?
To wrap this up. Letters flipping are not what I'm talking about. Even if you do flip the letters you still share other similarities. Paradoxitype is a specific lens on MBTI and it is far more profound to people and their lives then anything you have said so far. Why don't you read up on it AND more importantly actually see how it applies to your life. You will find some PROFOUND insights after you are done. Then come back and talk to me after you have experienced what I'm saying and have not just talked about it.
Ok, class is over. Put your note book away.
