All right. So I understand MBTI types and how they are determined, and I mostly understand the Eight Cognitive Functions and can give examples of each function. I see what the pattern is for putting them in order (Fi Ne Si Te, Se Ti Fe Ni, etc.) What I don't understand is how the two are correlated.
How did they determine and assign those combinations for all the different MBTI types? Was it through induction (reading the type description and assigning the combination) or deduction (combination first, correlated to type second)? (Hope I got induction and deduction straight, but that is entirely beside the point!)
Also, is there a way to just look at a code and know if it's a Judging or Perceiving type, without having to straight up memorize them all?
