I have two members of my family who have been difficult to type, and I am collecting information on what makes people behave against their type, especially in the family context. So, does anyone care to share (generalized!) portraits of family types who are "off" for whatever reason--how they manifest counter-type behaviours or do seemingly untypeable things?
I'll start off. (Note: They have never taken the official MBTI, just internet approximations.) Sister 1 has always tested as an INFP. I can see that in her childhood, but she shows no orientation in adulthood toward Kiersey's Idealist traits--especially not self-actualization, which she laughs at me for being interested in. She has an F preference, I am pretty sure, being sensitive, but she is interested in science and is much like her INTJ boyfriend now; I wonder if he is the reason for this. She also has always been an amazing artist. I cannot figure out her type for sure.
Sister 2 has tested TWICE as ENFP but this cannot be true. She is a textbook ESTP: as early as two years old perfect strangers would watch her and tell my mother, "I think you've got your boy there." To this day she is proud of being "one of the guys." She fits all the descriptions of an SP Artisan. I just don't know why there is such a discrepancy in the test results.
