Handedness and MBTI?

[coffeeloverfreak]

I wonder if there's any correlation between left- or right-handedness and MBTI?

I have read conflicting things on the subject, which isn't surprising, considering how much of the psychology and biology of handedness has been completely rethought by science in recent years.

Still interested in this topic, as a leftie. How many of us are there here? I wonder if it's higher than the statistical population percentage? It's been suggested that lefties are stastistically smarter, so I wonder.

I do everything correlating to thinking left handed, and all athletics right handed.
I consider myself a left bec that is what i write with, therefore i use it the most.

[Tokey41]

The big three: eating, writing, and throwing.

I eat and write with my left and throw with my right. Usually fine motor skills I do with the left but not for everything.

Im the exact same, huh, ironic. Maybe there is a trend going on here?

[Jgib5328]

I write, eat, brush my teeth with my left and I am left eye dominant. However, I do all sports with my right, except I am goofy footed for snowboarding and I've done archery lefty. The thing about me is that I can do everything with both sides. I have a mastery of writing with my right hand, which came naturally and I can pretty much do everything with both sides, but I do have a hand that I prefer. I call myself ambidextrous though, but I'm not exactly ambidextrous I'm just stuck in the abyss of handedness.

[AgentofGaming]

I do everything on my right hand, then I noticed that I wasn't putting my left hand to use.
So I've been trying to use my left hand more now I use my left hand for holding my cup and using napkins while eating.

[Santana28]

i dont know, but the INTJ side of my family are all left-handed. I was originally left-handed but my teachers and my mother forced me to work right-handed. I work right-handed but when i dont think about it i will pick up items and do things with my left hand first. My son is taking most certainly after my side of the family, and he's left handed.

[Ace1337]

Right or left brained maybe, but handedness has nothing to do with MBTI.

[JTG]

I eat, write, and fish left handed. Most everything else i do with my right hand. That's just preference though; i can do most things almost as well with either hand albeit less comfortably.

[sonofone]

right but I can use both for most things.

[AgentofGaming]

Currently a higher ratio of left-handers among us than the general population hmm...

sidenote:
my mind played a trick on me, I thought I saw "handsomeness and MBTI". :rolleyes:

[yondyr]

Left handed here, only INTJ in family, only lefty too.

[Duncan Cade]

I highly (hightly?) doubt there's any connection between MBTI type and Handedness.

There isn't any correlation. I guarantee most of the people on this forum are right handed. Only people whose handedness is not common will respond. Lefties generally are more interested in talking about their handedness than righties because it is less rare. Same reason why there are all of these INTJs talking about their personality on this forum, if our personality type was more common, there would be a lot less people here.

However I did read somewhere that it is more common for J types to be right handed and P types to be left handed (relatively or course), but not a specific type.

Looks like plenty of righties are responding to me.

[yondyr]

I highly doubt theres any correlation between MBTI type and physical characteristics unless we all have a mole on our...nvm. :)

[Windmill]

There could be.

Handedness is in correlation to the brain, right? Well, the right hemisphere is certainly the more N-centric one :P

[Scorne]

Left at drawing/painting/mouse, right at writing, throwing. I should really train my left to write as I reallllly prefer it, especially sitting on a desk with another person. (Reminds me of school, I always sat next to a left handed person so that we wouldn't jog each other)

[RunAmuck]

I write with the left (there's a pun in there somewhere) but shoot, bat, and throw with the right.

I eat with both! :)

[Haphazard]

I use my right hand for most things (like writing and etc) but I can do a lot of things acceptably well with my left hand, including write. I'm far from ambidexterous, though, but I think it might be because a lot of what I do requires use of both hands in activity, like typing and knitting.

[eternaltriangle]

In my gifted classes, about 25% of people were left-handed. In my family, there are only two leftys (myself included), but they both are studying for or have phd's. Golfing and clipping my toenails/fingernails are the only things I do better with my right.

Runamuck, you have the best avatar ever. I love that character.

As for explaining the link between left-handedness and MBTI... Consider that brain dominance is strongly predicted by which hand you use. Checking the right vs. left brained numbers using the advanced search function finds a 57-43% split in favor of left-brained people.

Over 95% of right-handed people are left-brained, while about 70% of left-handed people are left-brained as well. Since 12% of the general population is left handed, and 88% right-handed (roughly), 55% of right-brained people are right-handed, 45% are left-handed.

It would be committing the ecological fallacy to say that ipso facto this forum probably has more left-handed people than the general public, but if you were to impute from the numbers above, 19% of this forum would be left-handed right-brained people, while 5.2% are left-handed left-brained people. At 24% (nearly equal to the estimate in the poll above), that is double the average proportion of people.

However, I don't think there is a direct link between being left-handed and being intj. Rather, we are more likely to be right-brained and therefore intuitive. Those qualities increase the likelihood that we will test as both right-brained and intj's.

My left hand is useless, except to hold things that my right hand is working on.

Haha, I find that phrasing quite funny for some reason. :laugh:

[Moriarty]

I was originally left-handed but my teachers and my mother forced me to work right-handed.

Wow. My mother told me she did the same thing when I was a toddler.

There are so many amazing similarities on this board, it's almost creepy. Almost.

yeah. its not really a big deal, but when i pick up a baseball bat or a guitar or something i just naturally grab it like a lefty would. i can throw and do other things left handed pretty well, although writing is difficult.

my son looks to be a lefty. i wish i were more confident in my lefty skills to help him out, as his father and all his father's family here are rightys.

and dangit, left handed guitars are more expensive!

[Moriarty]

I'm able to do some things left-handed, but I wouldn't consider myself ambi. I had a shoulder surgery early last year (subacromial decompression) and while my right arm was in a sling for about a month I found it quite natural to do things the left-handed way. Everything *except* writing. Trying that with my off hand is very unnatural to me.

As for lefty guitars, consider a classical or flamenco style one. They're the same on top and bottom since they don't need a pick guard. Just a tip.

[veritas]

Interesting that a lot on here share my description - lefty eating and writing, but righty in sports except for swinging a baseball bat/golf club.

[Alcuin]

I honestly dont see it tied to MBTI.

The most interesting correlation between individuals and handedness I've seemed to experience is that most gay people I know are left handed. There was a Canadian study on it (I'm trying to find a link) that delved into it.

I'm not sure about handedness, but check this out:

"Measuring people's finger patterns may reveal some surprising information...
...
Animal models have indicated that androgenic steroids acting before birth might influence the sexual orientation of adult humans. Here we examine the androgen-sensitive pattern of finger lengths1, and find evidence that homosexual women are exposed to more prenatal androgen than heterosexual women are; also, men with more than one older brother, who are more likely than first-born males to be homosexual in adulthood, are exposed to more prenatal androgen than eldest sons. Prenatal androgens may therefore influence adult human sexual orientation in both sexes, and a mother's body appears to 'remember' previously carried sons, altering the fetal development of subsequent sons and increasing the likelihood of homosexuality in adulthood.
...
In women, the index finger (2D, second digit) is almost the same length as the fourth digit (4D), although it may be slightly longer or shorter; in men, the index finger is more often shorter than the fourth. The greater 2D:4D ratio in females is established in two-year-olds1. Because all non-gonadal somatic sex differences in humans appearto be the result of fetal androgens that masculinize males3, the sex difference in the 2D:4D ratio probably reflects the prenatal influence of androgenon males4.
...
This sex difference in 2D:4D is greater on the right hand than on the left (Fig. 1a), indicating that the right-hand 2D:4D is more sensitive to fetal androgens than the left-hand ratio. The right-hand 2D:4D ratio of homosexual women was significantly more masculine (that is, smaller) than that of heterosexual women, and did not differ significantly from that of heterosexual men. Thus finger ratios, like otoacoustic emissions5, suggest that at least some homosexual women were exposed to greater levels of fetal androgen than heterosexual women...

2D:4D ratio of homosexual men was not significantly different from that of heterosexual men for either hand (P > 0.09). However, segregating male subjects based on birth order provided support for the role of fetal androgens in male sexual orientation. The more older brothers a boy has, the more likely he is to develop a homosexual orientation2. Confirming these reports, we also found that only homosexual men had a greater than expected proportion of brothers (P< 0.01) among their older siblings (229 brothers:163 sisters) compared with the general population (106 males:100females6)."

Left handed. Left eyed too, and left legged even!
