I recently did a short version free MBTI. It showed by Feeling function slipping into Thinking by 1%. In addition, my Extroversion was barely captured–so it would seem. However, I am an extroverted feeling type.
The tendency to separate the opposites as much as possible and to strive for singleness of meaning is absolutely necessary for clarity of consciousness, since discrimination is of its essence. But when the separation is carried so far that the complementary opposite is lost sight of, and the blackness of the whiteness, the evil of the good, the depth of the heights, and so on, is no longer seen, the result is one-sidedness, which is then compensated from the unconscious without our help. C.G. Jung Mysterium Coniunctionis (1955). CW 14: 470
The closeness of the E/I and F/T in my typology (close to) paradoxically reflects much greater differentiation of their functions in my psyche. For me the transformation from ENFP to, in actuality, something like XNXP is hard won.
My short version Big Five never changes much; I’ve been more agreeable and less introverted at times. I wish it captured realistic/unrealistic and, in doing so, could gain-say deeper neuroticism.
