Women INTJs

[GOD]

I would be interested to hear from women INTJ's as to whether they have a greater degree of male siblings in their families.

(It’s just that I believe its going to be more prevalent in families that genetically have a higher predisposition to male children).

One interesting observation I made once, is that of the 20 chief executives from the biggest listed companies that approximately 2/3rds of their children were FEMALE. (I used to read stories about how people achieve corporate success). It’s my belief that the Chief Exec position is more touchy feely and those males with greater EQ are more likely to have daughters.

Any talk in the family about generally having boys? especially on your fathers side...

[fripping]

my intj g/f is also an only child. by registering here, i hope to understand her better. ain't that sweet.

[Jezebel]

Any talk in the family about generally having boys? especially on your fathers side...
For current generations (I'd have to look it up to go back further) it has been like this:

my father's family (grandparent's children) - 3 boys, 1 girl
1st generation cousins - 5 girls, 1 boy
2nd generation cousins - 8 girls, 6 boys

Actually, I wasn't sure if you meant environmental factors or genetic. If genetic, I do have a half brother and half sister on my mother's side. However, I have never lived with them or had much contact. I don't know what the rest of the family is like on my mother's side.

[thegnat]

I'm an only.
With probably about equal amounts of women and men in the family. As of now women are more prevalent (it really was exactly equal with women and men on that side, actually on both sides).

Although my grandpa's horses always had boys until only one time :)

[GOD]

Interesting,

I believe there is something that helps determine the likeliness of female INTJ's (And for that fact male INTJ's).

1) Either is straight forward genetic - father/mother etc are INTJ's and hence the child has greater propensity (Just like any genetic trait)
2) Follows a likelihood of having male children. Hormonal bla bla...
3) Could be first born has a greater impact. <- looks quite useful.
4) Could be just environment (Which I disagree with, I was way too INTJ just to be reflection of my environment).

[Jezebel]

I grew up as an only child with my father. My best guess for my father's type would be ISFP (he refuses to take the MBTI). I don't know any other INTJs in my family... in fact, I don't know anyone in my family I would peg as any variety of NT.

While I think personality type may be genetic (as in, we're born with it), I have serious doubts about it being hereditary based on my own experiences. Not that I'm trying to disprove your theory. Just providing data.

As for genetics - I never knew my dad well enough to say yes or no. Mom I would guess is ESFJ. Their families - perhaps. I don't know.
I don't think it's the second.
Hmm....I wouldn't know on that one. It's kind of environment-ish though isn't it?
Definitely not environment.

I'd guess genetics. Just because the others don't quite seem to fit.

[Rei]

I have a really REALLY girly, ESFJ elder sister; we're 8 years apart and we're only related maternally. My mother may be an INT... Borderline J. My dad is probably ISFJ.

On my dad's side I have... I think 3 or 4 boys, and 1 girl. (I'm not close with my paternal side. Plus my dad has 2... or was it 3? elder brothers and 2 younger sisters. I've only seen his second brother and his family within the past several years... so I've lost track of everyone else's kids)

[hr]

Paternal:
Last generation immediate family - 3(or 4) male, 2 female
This generation - 3(or 4) male, 2 female (including myself)

Maternal:
Last generation immediate family - 1 male, 2 female
This generation - 3 female (including myself)

[Bossy Mom]

I am the eldest of 9 children, with 6 brothers and 2 sisters. One of my sisters is also an INTJ and the other is an ENTJ. All of my brothers are wimps with one being an ENTJ. My dad was an ENTJ and my mom - just a Betty Crocker type of mother. I used to be an ENTJ, but time has proven to me that I'd rather just live in more solitude, so thus I have developed into an INTJ.

[Firelie]

I have one brother.

My dad has one brother and one sister.

My mom has one full brother and like 6 half brothers (her biological dad was kind of a manslut).

[deicruxified]

i am the eldest. however since my mom wants a boy to be the firstborn her parenting approach was quite different. but then it was not that difficult for her because i'm a growing intj and have always been independent.

[Elizabeth9999]

i'm not sure this has validity. intjs are more likely to be male, but i don't think this necessarily means that families with intj predispositoin are more likely to have male children. i think such families have on average the same number of male and female children, and it's just that the male children are more likely to be intjs. the female children might be more likely to be infjs, for example.

my mother has two sisters (she is one of three female children) and my father has four sisters (yes he is the only male child out of five children)

i have one sister and one brother (so there are two female children in my family out of three children total)

[mind_wander]

I don't know about both sides of my family. All I know on my father side has 5 brothers. The my mom side, has 5 sisters and 2 brothers; in addition to be one who is unrelated, but feel like family.

[Rei]

OMGsh, I thought you were a guy!

[Jezebel]

OMGsh, I thought you were a guy!
Whoa, me too.

[mind_wander]

I am a guy. lol, where did you get that conclusion. I guess as an INTJ can be manipulative. ON my mom side, has one adopted sister [unrelated- but I still treat her like family]. If that is what you were referring too. I just wanted to jumped in, lol. since everyone is talking about family. Hard to avoid.

[Jezebel]

I am a guy. lol, where did you get that conclusion.
Because the thread requested feedback from INTJ women and you responded. Perhaps you could specify that you aren't part of the group the questions were directed at but you'd like to answer anyway? :suspicious:

My first inclination was not to phrase it as a question/request, but I'm trying to work on my 'friendly' image. ;)

[mind_wander]

lol, yeah some of the conversation was so tempting. Thanx, for not going off at me, not part of the group; just a friendly guy popping in. Ok, me go bye bye now. Next thread......

[Santana28]

only child.... father was probably INTJ and BPD. Not sure what my mother was... shes probably an ENFP like my husband ;)

[GOD]

i have one sister and one brother (so there are two female children in my family out of three children total)

The question is to see whether there is some correlation with the observation that Chief Exec's had a surprising number of daughters (having daughters is normally a function of genetics... I would hope lol lol...) with the genetic trait of INTJ. I believe an INTJ has a specific brain pattern (Probably the way it’s wired) and am interested to see if there’s any anecdotal evidence to back this up. *

Yes you could be right that as a pool INTJ/INFJ might have a better correlation. But this is just looking at INTJ.

I'd suggest that the search for causality focus on the degree of masculinity of the children, rather than the portion of children who are males.

The two main characteristics which best differentiate INTJ's from the general population are not introversion or judging (which are both fairly common) but iNtuition and Thinking:

"About 70 percent of Americans are sensors...." -(To view links or images in this forum your post count must be 2 or greater. You currently have 0 posts.)

So we know that whatever conditions we seek must, if they exist, predispose a person to be an iNtuition person and not a Sensor person.

The next important category is Thinking/Feeling: "This is the only personality type category related to gender. About two-thirds of all males are thinkers, and the same proportion of females are feelers. There often are problems in the workplace for those who don't conform to their gender's preference. For example, a feeling man is labeled a "wimp." Much more negatively, a thinking woman is "unfeminine," she "has a chip on her shoulder" or much worse."" (-To view links or images in this forum your post count must be 2 or greater. You currently have 0 posts.)

So, if we assume causality, being a male doubles one's chances of becoming primarily a thinking rather than feeling individual. *From here we can veer off onto a tangential nature/nurture debate, but let's not. *Rather, let's look at those influences and their constituent components as contributors to a vector which ultimately points more in one direction or another. *So, to the extent that the sum total of all forces making an individual more Thinking outweigh the Feeling forces, one will be primarily a Thinker.

The result of being an iNtuitive+Thinker is a Rational, whom Keirsey states: "are very infrequent, comprising as few as 5% and no more than 7% of the population."

- (To view links or images in this forum your post count must be 2 or greater. You currently have 0 posts. k&cd=1&gl=us&client=safari * <-- This is a cached link from google - Keirsey has since obscured this particular page )

So how does one become a rational? *Let us start with the more quantifiable information, herein proposed to be the levels of chemicals observable within the human body. *The following study proposes that with regard to cognitive function as correlated to sex hormones like testosterone and estradiol (a form of estrogen) there are optimal levels of hormones to maximize cognitive function (and that higher isn't necessarily better) To view links or images in this forum your post count must be 2 or greater. You currently have 0 posts. . *Because these tests appear to be biased toward more rational individuals (insert here any of many references showing that Rationals tend to score higher on most standardized tests), it seems possible that these optimal levels of hormones cause people to be more Rational.

While there are some studies that show that individuals can be impaired by de-optimization of their hormone levels, the prospect of predisposing developing children toward Rationality by modulating their hormone levels has yet to be explored.

Consequently it seems logical to propose that certain levels are more likely to promote thinking function. *Here is a study about which I will say nothing other than to note that the reader may glean useful bits of information but should also be careful to note the perspective and disposition of the source: To view links or images in this forum your post count must be 2 or greater. You currently have 0 posts.

So it would be good if we could dig up some studies showing developmental hormone levels correlated to personality types. *This would tend to support or refute the theory that these levels are factors in the vector of Rational/non-Rational.

I am still working to develop theories as to Introversion/Extraversion (lots of data here, and intro/extra are defined differently in different places) and Judging/Perceiving (perhaps this has to do with level of aversion to risk, especially with regard to risk of being wrong?).

[TeleportThis]

I have one older sister. My mother has two sisters and two brothers. My father has two sisters that are twins.

[cielo market]

Second-born.

From the same parents: I have an older sister, younger sister, younger brother.
From a different mother: I have another younger brother.

We're pretty evenly spaced out except for the youngest boy. Ironically from oldest to youngest: Extrovert, Introvert, Extrovert, Introvert, Extrovert.

[Panthera]

Hi everyone. My first post and I am a female intj with 5 brothers (all older).

[aelan]

I'm the oldest with 2 younger sisters.

[Bossy Mom]

I am the oldest of 9 children (3 girls and 6 boys). I am the super-responsible one with the greatest amount of curiosity and addiction for learning. None of my siblings has those characteristics to the extreme that I do. My two sisters are responsible (not super-responsible) and assertive (one thinks she's Calamity Jane). My brothers are all wimps except one. My father was an ENTJ. And they all live within 20 miles of each other. I live 1600 miles from them. I love them, but when I'm with them over a week, they drive me crazy.

[Cub]

I am an only child

[Headstrong]

I'm an only child.

[toonia]

I am an INXJ and grew up the youngest in a family of deeply sensitive Fi dominant people. Of the context of my family I am the least emotionally expressive and the most able to be detached when need be. I also tend to handle personal conflict in a very different manner than they do. My mom has me listed for power of attorney to make decisions in case of medical crises because she knows my siblings are too passionately invested in decisions and/or overly influenced by their spouses. If type is genetic, I would say that I am more likely an INTJ influenced towards F by my environment. If it is environmental, than the combination of my strongly F family, and the strongly T nature of my academic upbringing and marriage have had a secondary influence on me. It is worth noting that the second layer of influence was of my own choosing. It was a deliberate choice on my part to marry a strongly rational, clear thinking man. I love my family very much, but there is one type of distance that is required because of the way I approach problem solving in a more distanced manner. They aren't able to negotiate conflict by dealing with information separated from how everyone feels about the issue and information. Then again maybe I am inherently an INFJ who compensated to gain more objectivity because of being in a strongly emotional context? Maybe that was Ni attempting to achieve balance from viewing every angle? In some ways I prefer that label. In the past it is more satisfying in debate online because opponents will attempt to discredit on prejudicial terms. It is a good feeling to challenge assumptions made prematurely.

[timewarpson]

I'm the eldest of three, with two younger brothers. The youngest is a half-brother. I was the overachiever and perfectionist of the family with my brother being the wheeler-dealer street smart type. He had to follow me in high school and I think that was a little tough for him. I was salutatorian of my class and the teachers were always saying to him, "Oh, you're her little brother..." Like others here I spent a great deal of time alone with my thoughts - immersed in enclyopedias, dictionaries and all manner of science reference texts.

My mother is an ENFJ, father an ISTP, and full brother is also an ISTP. The youngest is an introvert as well but I don't really know him so I can't say what his type is. My mother talked enough for the rest of us; virtually non-stop. My father had an intellectual streak and did introduce me to engineering and Ayn Rand. Both of them had mental health issues, however, which made for a very unstable environment. Therefore, I believe I sought to control what I could, basically myself, and vowed that I would use my mind to rise above my poor circumstances. I find now that I'm older my I/E is borderline and I am fairly good at extemporaneous speaking, which makes social interaction and the sharing of my ideas with all types much more facile.

i have one sister and one brother (so there are two female children in my family out of three children total)

Do you think that the T/F divide is just a lead into the nature/nurture debate? It seems like this could easily descend into that. However, I think it's a valid area to probe. For instance, I used to test ENFP. I honestly don't know if I was really that way, or that's just how I thought I should answer, because that's what society thought I should be. I have never been particularly good with emotions, so I have a hard time believing that I was actually an F. Being a young, scatter-brained NP is possible. However, being J has nothing to do with being neat. I know plenty of cluttery NJs. Back on topic, I come from a largely female family and none of us are particularly F-ish. My mother is probably an ISTP, maybe INTP....I've never been sure.

[phoenix]

I'm a first child, younger brother. On my mother's side there is a higher liklihood of having girls. On my father's side, a higher liklihood of boys.

Take it as you will.

[GOD]

I'm seeing a propensity for INTJ's to be first born or only child...

Maybe the T is simulated more in First borns as parents generally expect more of them (treat them more adult like). And the J is simulated through the controlling of younger siblings...??

I think the more "independent" first child (before younger brothers and sisters appear) could be a factor for the I. Also, Just maybe the first born spends more time being introverted as they bond more with the younger sibblings and defer spending time with a similar age group (You don't need to be so E in a safe family environment).

I'm the youngest of two in my family but very much an INTJ. My elder sister is an ISTP and we've always gotten on very well together.

[Fiordispina]

Only child - female. Little interaction with other children until school age.

[Aoiluna]

I am the oldest child, with a younger brother born about a year and a half after me. I think that us being so close in age and socializing with each other may have had something to do with it as well. I played more with toys made for boys, and grew up with many guy friends. In case you wanted to know, my mother is an esfj and my dad possible a estj, but he has not taken the test. My brother is also an esfj like my mother, and I seem to be more like my father. i find this interesting because i get along so well with my esfj family members, whereas me and my father seem to be enigmatic to each other. or just on a weird sense of understanding. he may be borderline istj as well.

[catd]

I am the oldest of 7. 3 females (same mother)/4 males (2 from different mother)
Mother - one brother
Father - one brother

I don't know what type any of them are but I know that none of them are INTJs.

[searcher]

I have a brother who is apparently "more of a girl" than I am.
Hahaha.
Grew up in a house with two guys (brother & Dad) & Mum, who I don't relate well to.
Or get along with for that matter.
Mostly guy friends.

[Cuivienen]

I have one younger brother. My mother has 2 sisters, my father has 2 brothers and a sister.

[vaguely dissatisfied]

my intj g/f is also an only child. by registering here, i hope to understand her better. ain't that sweet.
I think it's very sweet.

I have three sisters and one brother. He's the youngest of five.

My two cents..........I think INTJism, like other types, is genetic and very little of the type is influenced by environment (just my opinion).

Oh yeah.......I'm the middle child.

[Antares]

Only here, but I've always been a 'tomboy'. I think my cousin is an influence; he's always urged me to be 'boyish'. I guess he could count for the 'brother' figure.

[azelismia]

I am also an only child, although My aunt is six years older than me and at times we lived with my grandma so she's kind of a functioning older sister figure.

[Double Victory]

I'm the oldest with two younger brothers and one younger sister. However, my sister wasn't born until I was ten, so I relate a lot more to my brothers (who are closer in age to me). I've always been a tomboy, and neither of my brothers are very emotional--one of them is an INTJ. My mom has never been feminine, and has been a blue collar worker all of her adult life. My familial environment definitely played a large part in my current personality.

[curiousjane]

My INTJ mother is a third born. One older brother. One older sister.

[quest ion]

I have a very girly elder sister, and an elder brother.
I think my external environment shaped me into an INTJ. Not so much from my family though.

[xanodel]

Only child, but grew up around cousins and extended family-eldest of all the first cousins on both sides. Mom's side of the equation is almost all girls, dad's side is all boys (though I've only met them once my entire life).

Genetically, I think I inherit from my mom's side-they're mostly N's. But dad's side is almost all S. While genes play a part, I doubt it's the most important factor considering the number of INTJ's with S parents.

[PRBori]

I'm the oldest child of two, I have a brother and a step-sister on my dad side which I've hardly known... that step-sister however does not see me and my brother as part of her family... nor do I really see her as part of my family anyway.

My mom has 2 sisters, 4 brothers for a total of 6. My dad, well let's say I never met all the brothers and sister, but I believe he had a total of 11 brothers and sisters, I never met most of them anyway... only know 5 of them

Is hard for me to tell what MBTI they are... all I can say is that we are worlds apart on how we see things...

[44sunsets]

I would be interested to hear from women INTJ's as to whether they have a greater degree of male siblings in their families.


Why only hear from INTJ women? Other people should be able to report just as precisely.

FWIW, I have two INTJ female friends who both have one sister each, no brothers. The thing that struck me in both instances is that their their entire family (including parents) seemed to be Sensing types, and they were the odd ones out, so to speak.

Which is quite similar to my situation. I'm an INFJ male in a family of 3 ISTJs (I have a younger sister). I've always thought of myself as the black sheep of the family. It's that whole gender-atypical type thing.

[Synamon]

I'm the oldest and have a brother and sister.

Does anyone think there are less female INTJ's because some of the more borderline ones give into society's gender based programming and end up adopting more female traits, ending up as an ISTJ or an INFJ?

[44sunsets]

Does anyone think there are less female INTJ's because some of the more borderline ones give into society's gender based programming and end up adopting more female traits, ending up as an ISTJ or an INFJ?

No. Personally I don't think it's possible to "change" your type, because that is something innate and hardwired into your brain. An INTJ woman would never be able to "morph" into an INFJ woman, they are completely different.

Everywhere you go in the world, you will find similar proportions of the various types. INFJ males and INTJ females will be very rare in the general population no matter where you go. In the global community, they may congregate and cluster in certain areas, but the general principle still applies.

It brings "balance to the Force", so to speak. INTJs and INFJs pack a serious punch -- the world would be completely different if they were a majority rather than a minority.

[Erika Redmark]

Some people say that the type doesn't solidify until the age of about thirteen, though. Whether this means that the uncertain letters of the type are still malleable, though, or if it just means that a parent can't yet type the child based on their observable behaviour, I don't know. (Someone linked to a page with three-letter types on the "what type would you want your kids to be" thread.) So either I used to be an INJ with F or T up in the air or I used to be an INJ who was destined to be an INTJ all along, it was just impossible to tell until I was sufficiently grown up. If all this is true, and the preferences aren't set from the beginning, but are decided upon along the way, then it would be possible for an IJ girl (according to this MBTI-for-kids theory, kids have two-letter types until the age of 6, then it's possible to observe their preference for whatever the dominant will be) to be nudged toward ISJ rather than INJ based on socialisation. Depending on how much of this is true.

ETA: oh, yeah, might as well respond to this thread. I have an older half-sister and a younger brother. The cousins in my generation are pretty much evenly split.

[FoxyGirl55]

Hi everyone. I'm an INTJ, and a lady; which I just recently learned is a rare combination. To answer the original question... I grew up in a family with four children, where I was the third. I have an older half-brother and a younger brother. My older half-sister (the oldest of the four children) was completely indifferent to me. I spent the majority of my time with my brothers and father. I was the invisible child, the "smart, quiet one," and I liked it that way.

[beverly penn]

I'm also an INTJ lady. I grew up with two brothers and 6 uncles, no aunts.

One brother is ENTJ and the other is INFP, I think. We've always gotten along extremely well. Obviously my relationships with each brother individually are very different. However, I don't think growing up around males has made me who I am...influence comes from everybody I've ever met, and my own perception of those people has formed me. Traits I like, I try to model - traits that bother me, I try to avoid.

[schwartzie]

No. Personally I don't think it's possible to "change" your type, because that is something innate and hardwired into your brain. An INTJ woman would never be able to "morph" into an INFJ woman, they are completely different.I'm not sure, 44. A problem with testing this theory is that the MBTI is self-reported AND self-assessed--that is, classification is based on answers a person gives to questions. The answers, knowingly (that "should" be given) or unknowingly (e.g. being tired when you do the test may increase "I" type answers, because of the need to recharge) are subject to environmental influence and the subjective state of the person. It would be difficult, at best, to control for this.

My own experience is that, for a couple of years, ending last winter, my sister and I were in a complete pressure cooker--each of us had family members in extreme distress--and were primary physical and emotional caretakers. For me, three family members were simultaneously very ill for a long time-a couple of years-and I learned where the end of my rope was....
The experience, I think, has changed my MBTI. I am much more balanced on the NTJ factors (closer to the centerpoint), and much more imbalanced on the I (extremely high I, where I used to be fairly close on the I/E scale). My guess is that either my thinking has indeed changed, or my self-recognition has improved, or my willingness to report false answers in order to be "normal" has diminished. Or some combination....It brings "balance to the Force", so to speak. INTJs and INFJs pack a serious punch -- the world would be completely different if they were a majority rather than a minority.
lol

[denaria]

I'm the elder of two sisters; my parents each had an elder brother and each produced a pair of cousins for me, two boys by my maternal uncle and two girls from my paternal uncle. Judging by actions, the entire generation is nuts (and at least two have medical records to prove it...); my sister, my younger female cousin and I are the closest to fully functioning human beings, the two male cousins are completely off the wall and appear to owe what (slight) ability they have to operate in normal society to education at a top public (US: prep) school. Sis and I have the best qualifications (sis has a PhD, I'm a qualified professional); I almost certainly have the highest IQ, with no 2 male cousin next, then sis, then no 1 male cousin (and all four of us are very clever). Don't know the girls well enough to rank them but they've never given any indication of being very much smarter than the average bear. The men and I are Is, the rest of the women are Es, would guess the men as both INTx and sis as ENTJ.

[dori]

im the second of 4. older brother and two younger sisters.
i dont know what types they are but we are all very similar in that we are independent, intelligent, rational and fairy reserved with our emotions.
we were all actively encouraged to be independent and self sufficient.

i have 3 children myself (2 boys, 1 girl) i would say they are all e's.

[overclockedgirl]

Maybe it's likely to work the opposite: if you have a lot of Fs in your family you become a stronger T. I'm the oldest of 3 girls; I'm 24 my sisters are 23 (IxFP?) and 22 (ISFJ). I have a brother who is 15 (ENFP). My parents are ISFJ and ISTJ. I read somewhere once that INTJs are more likely to be the oldest child.

[Isolation]

I'm a female INTJ middle-child... of THREE GIRLS! :p
