I have found that there is a direct relation between Jungian typology and Freudian psychosexual development. It appears that Jung and Freud were typing people according to the exact same categories.
I have been verifying this relation for about a year now, and it all just fits in I believe.
It appears that each MBTI-type correspond to 4 of the psychosexual roles of psychosexual development. Not only 1 role as some might believe.
Every Jungian function corresponds to a Freudian ‘stage’ - Or ‘problematic’ to be exact. Since there are 4, not 3.
The direction of a function decides whether it corresponds with the progressive or regressive role of the ‘stage’/’problematic’
The ‘Unification theory’ is available on my web-site:
