I was hoping the complexes would be based on strength or something we could measure.
Case number 1) is a standard Myer-Briggs INTP ie. see Blue Wolf test result:
Case number 2) is a standard Myers-Briggs INTJ.
Case number 3) is unclear and not really acknowledge by the Myer-Briggs as something we can observe. However the standard MBTI test will always give it a name.
The trouble with Myers-Briggs is that 16 is boring now in 2020 and I'll be more interested in being able to observe 32 types instead.
