Especially how the elements are defined.
Yes, I agree.
And this has already been covered.
Socionics puts more emphasis of "Jish" qualities on Judging functions, regardless of whether they're extroverted.
This then makes types that have a dominant introverted Judging function sound more "Jish" in Socionics than in MBTI.
And it makes types that have a dominant introverted Perceiving function sound more "Pish" in Socionics than MBTI.
And, lastly, each theorist emphasizes different things they believe to be true about the functions.
This exists within the "MBTI" world, between different theorists.
It exists within the Socionics world, between Socionics theorists.
And it exists between "MBTI" theorists and Socionics theorists.
And, lastly, it exists between Jung and all of them.
That doesn't mean, tho, that when they're trying to describe Extroverted Sensing, that they're not trying to describe the same thing.
They may emphasize different things about it, they may disagree about certain things about it, but they're still trying to describe the same thing.
10 Different Painters + Same Scene = 10 Different Paintings
Some will be more alike than others, some will be better than others, some will focus on things other didn't even paint.
Regardless, the underlying scene was the same.
Our job is to figure out which painters were most insightful and accurate, and what was insightful and accurate about what they painted.
