# Thread: Science Project: MBTI Patterns in Families

Sister: ISFJ
Brother ISTP (probably)

If I may have one request, could you find out if it is common for a single MBTI type to occur more than twice within one family (parents + children)? My hypothesis would be that it isn't.
Correction, for if you're still in this:

Mother: ISTJ
Father: IXFP
Me (being the oldest): INtJ
Sister: INFJ
Brother: INTP

You might take into account that insights can keep evolving...

2. Father ESFP
his brother (Dec) ENTP
his sister ENTJ
his mother (Dec) ISFJ
his father (Dec) ENTJ

Mother INFP
her sister ISFJ?
her brother INTP
her other brother (dec) ESTP
her father INTP
her mother ISTJ

My Brother ENFP
Me INTP

3. mother: ENTP
father: INFJ

younger sister: ISFP
younger brother: ENTJ

me: INXP (leaning towards INTP)

Need I say my sister sometimes feels a bit lost among all those Ns?

Edit:

Those above all did the test. The following are educated guesses:

mother´s 1. older brother: ESTJ
mother´s 2. older brother: ESFP
mother´s older sister: ESFJ

mother´s mother: ESFJ
mother´s father: INTJ

4. mom ISTJ
sister ESTJ
me ENFP
mom of mom ISFJ
mom's brother ISTP
other sister ISFJ

damn, basically me and dad only Ns in family

5. Great project!

Me = ESTP (tested and confirmed)
Dad = ESTJ (tested and confirmed)
Brother = INTJ (tested and confirmed)
Mom = ISFJ (suspected, will confirm today or tomorrow, OK?)

6. Much of these are guesses:

Sister INFJ (has taken official test and confirmed result)
Mother XSFJ (does not want to take the test)
Dad ISTX (also does not want to take the test)

Grandma ESTJ
Grandpa ISTP

Other grandma: No idea

Aunt #1 ENFP (took one of those online thingys, not the official test)
Cousin #1 ENFP (same as aunt)

Other aunts: ESFX, ISTJ, no idea on the other one
Other uncles: ENFX, ENTJ, XSTP

Other cousins: ISFJ, ISXP, ISTP, ESFJ, ESTP, INTX

7. mom: enfp
dad: no idea since im a bastard
siblings: no hab
grandma: istp, intj or intp
grandpa: no idea since he died when my mom was a kid

i think you should consider grandparents types as well, because some many genes can jump over a generation or two

8. Mother: ISTJ
Father (not biological, and the only one I know): ISTP
Grandmother (mother's mom): ISTJ
Sister (only half by genes, always lived together): ESTJ
Me: INTP

9. These aren't verified so might not be entirely accurate, but they seem accurate:

Me: INFJ
Brother: ISTJ
Mom: INTJ

10. Me: INTP
Mom: INFP
Brother: XSTJ

Grandmother (Maternal): ESFJ
Grandfather (Maternal): ISTJ

Grandmother (Paternal): INTJ
Grandfather (Paternal): ENFJ

Aunt (Mother's Side): ISXP
Uncles (Father's Side): ESTP, ISTJ
Aunts (Father's Side): ESTP, INTP, INFP

Cousins (Mother's Side): INTP, INFJ, ISTJ
Cousins (Father's Side): ESFJ, ISTP, ESTJ, INFP
