I try to get a bit more into socionics theory. I've noticed a lot of people say that the correlation between MBTI and socionics is just theoretical and your MBTI type doesn't have to suggest your socionics type. I have a question... How is it possible? Socionics uses 8 functions to describe the types, MBTI uses 8 cognitive functions, so how is it possible, that when a person is for example an INFJ in MBTI he can be an ENFp in socionics? INFJ in MBTI uses Ni+Fe while ENFp in socionics uses Ne+Fi. How is it possible that a person can use Ne+Fi in one typology and Ni+Fe in the other? Functions are functions no metter what typology it is. Or am I wrong? I just think if someone is an INFJ in MBTI he has to be an INFp in socionics because of the functions (INFJ Ni+Fe, INFp Ni+Fe).
