MBTI

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.

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.
