The introvert/extrovert (object/field) aspect of functions doesn't exist

[krieger]

Introvert Judging functions and Introvert Perceiving functions have in common that they are subjective. However, this "subjectivity" refers to two different kinds of subjectivity that are so different that they should not be called under a common name. The first (Introvert Judging) refers to how a certain belief that a person holds is subjective because said belief is not a matter of direct proof, but something the person has come to believe by building a personal model of how the data connects behind the screens. The last (Introverted Perceiving) is subjective in that it signifies the private, personal experience of the person that s/he does not (can not) share with others. These are two different forms of subjectivity. The similarity is weak, and therefore not a good basis for a primary trait in the socionics model.

Object/field (aka introvert function/extrovert function) is a weak, superficial descriptor. Not a primary trait.

If any of you want to understand what introversion and extroversion (in relation to TYPES, which I do not dispute the existence of) are really about, try to figure out the Limiting/Empowering and Static/Dynamic dichotomies. Those are what the real substance of socionics lies in.
