I "know" I'm ENFp, but sometimes exhibit strong introvert behaviors. I think this has to do with the kind of people I surround myself with. I've been surrounded a lot in my life by S-type with a 100- IQ (no offense intended), which caused me to withdraw. But when I'm with "my kind", I'm am extremely extroverted and a typical ENFp. E/I the MBTI or Big 5 way very much depends on who you surround yourself with.

This is both a pro and a con: MBTI is currently closed for scientific research, which is why it has become static. Socionics has a lack of agreement, but potential for research. Perhaps ultimately Socionics will be assimilated into psychology and the name will go into oblivion. Photographic VI sucks.

The scientific validity of MBTI is questioned: has research led to the theory, or the theory led the research to find fitting answers? Well, The Big 5 answers that question, it provides both confirmation and correction for MBTI. I will look up an article on that later.
