I have a friend I am trying to type in the MBTI system. I wrote up the difficulties in typing her here. The basic problem is that she has a cognitive function stack that is arguably something like Ti+Ne+Fi+Se. But there is no MBTI type with that stack, so I am having to find a "best fit".
After much thinking, I believe ENTP is the best fit for her. This makes Ne+Ti her dominant functions. The problem with ENTP as a type is that the ENTP cognitive function stack is Ne+Ti+Fe+Si. This would require her to be Fe in the tertiary function, when the test results in the linked post seem to show that Fi is a strong function for her. She is also strongly more Se than Si, but this is not so important since it is an inferior function.
I could view her as some kind of ENTP / ENFP hybrid, with an ENTP preference. But does MBTI allow for that? I could view her as an Ne+Ti dominant, and then just consider her Fi as a strong tertiary function that cannot be explained by MBTI. In the latter case, she would have to live without a type.
What is the best way to describe and classify such an individual?
