[MBTI] Why does the unnaturalness that comes out of trying to overcome inferior functions occur?

Differentiation of personality types begins in childhood. For example, the two attitudes 'extroverted' and 'introverted' are actually found in children. Unlike the dominant function, the inferior function is relegated to the unconscious and is not used as frequently, so the response is inevitably slower than the dominant function.

[MBTI] Should inferior functions be overcome? Can they be overcome?

Attempting to overcome an inferior function is an attempt to pull up an inferior function belonging to the unconscious into consciousness and place it under control. If one tries to forcibly pull up an inferior function, the whole of the primary to tertiary functions belonging to the conscious mind collapses, and the more one tries to pull up the inferior function, the more it descends from the conscious mind.

[EQ] Habits that increase the intelligence quotient of the mind. From the manager onward, title and EQ are inversely proportional!

EQ is the ability to take optimal action by controlling one's emotions while understanding oneself and others; when EQ was compared with job title, EQ was highest in the manager class and then tended to decrease as one's title increased.

[MBTI] An Introduction to Typology and Misconceptions about Extroversion (E) and Introversion (I)

It is commonly recognised that extroversion (E) is 'diplomatic and active behaviour' and introversion (I) is 'shy and withdrawn behaviour', but this is quite different from the original meaning proposed by Jung. Essentially, it is about the directionality of the mind's energy, with extroversion being "going outside of oneself to seek and gather energy". Inward is "seeking and going to gather energy within oneself."

[Career] Why do low performers increase after middle age?

Middle performers have no problems and therefore are left alone for better or worse by the company until their mid-30s to mid-40s, when they are in the prime of their working lives, and when they finally reach their mid-40s, they are treated as low performers and subject to release, which I felt was a terrible thing, but on the contrary, if they knew such a future was waiting for them in ten years' time, However, if they knew that such a future would be waiting for them in ten years' time, they would have a sense of crisis and could take measures to prepare for it from their early 30s.
