I am an ENFJ-T.

So I have revised what I have learnt from MBTI, and produce the following thesis:

Resolving Absurdity in MBTI Research

Yup, MBTI is still developing. While the psychometrics make error, chauvinists in psychology will jeer at them, and call MBTI pseudoscience. That's so absurd, since meagre of the critics do rectification.

The personal inventory of MBTI keeps evolving, from Form G (93 questions), Form Q (160 questions) and the most accurate of all, Form M. I personally feel that using statistical method to judge one's MBTI is very absurd, for it is arbitrary. As far as I am concerned, we shall understand the theory of type (and thus psychological functions) before assign an MBTI Type by ourselves.

Here is the schema of an INTP:
https://en.wikipedia.org/wiki/INTP

Dominant: Introverted Thinking
Auxiliary: Extraverted Intuition
Tertiary: Introverted Sensing
Inferior: Extraverted Feeling

In reality observations, we find that tertiary one is inaccurate. We see that INTP is often argumentative when arguing with feelers such as ENFJ and ESFJ. Making a sound argument is a mode of extroverted sensing. So we can see that the sensing function of an INTP can be both extraverted and introverted, and this is what Form M wanna rectify on past schema.

As a corollary, we can derive, while past schema find it ridiculous, that:

ENTJ, ENFJ will exercise introverted sensing (thus they feel insecure very often)
ESFJ, ESTJ will exercise introverted intuition (thus they are imaginative enough to produce novels)
INTP, INFP will exercise extraverted sensing (thus they become knowledgeable)
ISTP, ISFP will exercise extraverted intuition (thus they are good at mimicking other artisan's style)
ISTJ, INTJ will exercise extraverted feeling (thus they become control freak)
ISFJ, INFJ will exercise extraverted thinking (thus they are actively listening)
ESTP, ENTP will exercise introverted feeling (thus they have bad tempers)
ESFP, ENFP will exercise introverted thinking (thus they are utilitarian)

The past schema gives biased orientation on tertiary psychological functions such that it should be corrected accordingly to avoid layman's misleading so as to stem the tide of quack's abuse.

It is not uncommon that an MK of IQ<100 can be mathematicians, as they are zero in socialization tactics. We see that many ISTJ and ESFJ teaches other math and they have common trait of extraverted feeling. In the past, no one would agree that an ISTJ will make arbitrary value judgment, but now Form M would say yes, which support Myers-Brigg's original claim the orientation of tertiary psychological functions should be the reverse of dominant ones.
