So what is the personality type of your mother, your father and your type?
What about your grandparents on your mother side and father side?
Please write your formula:
MOTHER TYPE + FATHER TYPE = YOUR TYPE
GRANDPA TYPE + GRANDMA TYPE = YOUR MOTHER TYPE
GRANDPA TYPE + GRANDMA TYPE = YOUR FATHER TYPE
Let´s see if there are any significant correlation or patterns.
Mother, Father, Me
ENFJ + ISTJ = INTJ
Maternal Grandfather and Grandmother
ISFP + ISFJ = ENFJ
Paternal Grandfather and Grandmother
INFP + ENTJ = ISTJ
I don't see much correlation if any from people's results. This is one of the weaknesses of MBTI, because twin studies have shown that personality is heritable...if the model doesn't predict this then that is evidence against it.
