McAlpine, Robert
Giannini’s model differs importantly from Myers’ in that it does not restrict us to just one predominant function pair associated with one’s preferred perceiving and judging processes. His model provides a greater degree of flexibility in the developmental expression of type-related behaviors as well as enhanced adaptive power for engaging and responding to our various environments.
The type code had another unintended effect, which was to elevate the E-I and the J-P dichotomies to the same level as the functions. I had always thought of myself as an Introvert and nothing else. I had also been taught that I was a Judging type and I had been told that “J’s decide quickly,” but that was not true for me. So there were holes in my preference framework where my experience did not fit what I was taught.
