I do believe MBTI may be correlated with genes if it was proven that a person's MBTI type cannot change.
Anyways my family:
Father: INTP, INTJ, ISTJ
The closest I can come up with for my father. It is really hard to type him. I'm guessing mainly because he is trying to force a fatherly figure on himself (ISTJ). I'm thinking INTJ is the closest for him.
Older brother: ENFP
Younger brother: EXFJ
half brothers dad: extp Xe,fe, Ti
half brother: esfp se, fi, te
so in my family, XeFiTe is the only consistent thread which constantly gets passed in preference over the TiFe/FeTi combo?? However we dont have Si popping up out of nowhere. We also dont have IXXPs either or Fe doms popping up either...
ex-dad-in-law: intj ni, te, fi
(his mom:estp, his dad: ixtp)
ex-mom-in-law: istp ti, se,ni,fe
(her mom: enfp, her dad: istp)
Dad: INFP Mum: INTJ Big brother no. 1: ISTP Big brother no. 2: INFP Big Sister: ISFP Me: INFP
Three INFPs in one family... wow! :O But I don't think this is genetic; maybe partly, but definitely not completely. Me and my brother take after dad, but for example my dad doesn't take after his parents at all.
Her head hung down
Gazed at earth, finally keen,
As the rabbit at the stoat,
Till the earth was sky,
Sky that was green,
And brown clouds passed
Like chestnut leaves along the ground.
My dad, maternal Grandfather are both INTP. I have an INTx uncle, as well.
I did not grow up in a house with any of these men, so there probably is a genetic component, then considering INTP is one of the more unusual types.
My stepdad's family(including my half-sister above who I grew up with) are mostly ISxx, which also points toward a genetic component. My maternal grandma and her daugher-my aunt are also both ISFJ, I believe, so my sister actually gets the ISxx thing from both sides, just like I have INTPs on both sides. My mom being ENTJ is a bit of a mystery.
Half sister (youngest of the two)- ENTJ
Is it that by its indefiniteness it shadows forth the heartless voids and immensities of the universe, and thus stabs us from behind with the thought of annihilation, when beholding the white depths of the milky way?
