It is with the introvert where typology actually becomes more philosophical. MBTI says that it is the first extroverted function which determines the level of conscientiousness; as to how someone comes across as a "judger" or "perceiver". This actually makes sense because only that which is extroverted can be accurately perceived by another(or judged
). So perceivers extrovert their perceivering function and thus appear to others as perceivers, and the same logic applies with judgers. In Socionics, the reverse is true. If one is IXXj, they will be described in a similar manner as MBTI IXXJ. Introverted functions cannot be observed by their very nature. But how can a function that is not extroverted be accurately perceived by another to exist. How can one be Ti or Fi and somehow come across as Ij. This seems to be a paradox. When writing on a forum, one is actually extroverting a function, making it difficult to type introverts. They share what they want to share. But, don't all people do the same? Most types aren't exactly an open book.
