What makes people right-handed or left-handed?

GOOD QUESTION What makes people right-handed or left-handed? minnesota By Kirsten Mitchell

April 18, 2024 / 10:28 PM CDT / CBS Minnesota

MINNEAPOLIS — What do Lebron James, David Bowie and Bill Gates all have in common? They're left-handed. While they're a minority of the population, they're not alone.

So why are we right- or left-handed? Good Question.

About 90% of people are right-handed, while 10% are left-handed.

"Some of the theories think it's because of the way our brains are wired," Dr. Nancy Segal said.

Segal says lefties often have a more dominant right side of their brain while righties have a more dominant left side of their brain. Why is still a mystery.

"Language was a very important development in human history and of course, language is in the left hemisphere and that might strengthen the right hand," Segal said.

Studies show which hand is dominant may be influenced by genetics, adverse birth events or even random chance.

I was right-handed, whether by my inclination or the inclination of my family to ensure that I used my right hand, "like normal people," but around age 8 I fancied the word ambidextrous, and practised writing and using my left hand. It was quite easy and now I wouldn't say I'm truly ambidextrous but ambidextrous-inclined. I can write quickly with my left hand though the handwriting is a little less refined than with my right hand. For a quick scribble I'll use either hand, whichever is closest to the pen or paper, but for a longer, neater exercise the right hand is faster and more legible.

The real pleasure of developing some use of my left hand was that it enraged my 12 years older, hothead brother. He was obsessed that everyone walk a certain way, swing their arms a certain way, held a fork a certain way (he was a HKLP in Nancy Mitford's language), use their right hand in preference to their left, and pretty much the family Nazi about everything.

The one particular disinclination of my left hand: jerking.

Lebron is interesting. He writes left-handed, but he shoots (free-throws, jump-shots, 3-pointers) right-handed (but obviously can finish around the rim left-handed). Similarly, he throws right-handed when throwing a football or baseball, and he golfs right-handed (badly).

I was born left handed. When I was 4 my mother started training me to do things right handed, starting with drawing. By 5 I had learned to print and I spent an hour a day printing with my right hand on a big chalk board she had installed in my bedroom. By the time I entered school at 6 I had been taught to write cursive and was fully writing right handed. During my first week in 1st grade I wrote a note to my teacher in cursive (which in the 50's was not taught until 3rd grade), and I still remember the shock on her face when she looked at my note. When it came time to enter 2nd grade my teacher told me I was going to go into the 3rd grade instead. I was not happy as I wanted to stay in the same class with all my friends. But I was not given a choice. Once in 3rd grade my teacher used me to help teach the other kids how to write cursive. I didn't realize until many years later that all she was interested in was making her job easier, but I got over it. In high school I had several classmates who would remind me occasionally that I had taught them how to write cursive when we were young.

My mother knew what she was doing.

All I can say is that it was a hell of a lot more interesting to be left-handed in the 60s or earlier, when it was still considered taboo and degenerate. Tim Curry once said he enjoyed playing “left handed” characters (Frank N Furter, Pennywise, the Lord of Darkness, etc.) because they were much more intriguing than the status quo.

R30, Lebron is probably like me - how I was taught is how I play sports. I throw a baseball right handed but I can bat right or left. He was probably taught as a kid by a right handed person.

Anything I learned on my own like embroidery or crochet, or tennis, I do left handed.

IMO, it’s easier for us lefties to adapt and use our right hands for stuff than it is for righties to use their left hand.

It's not a terrible thing to use an unfamiliar hand for an activity. That FORCES the brain to create new neural pathways. More neural pathways = more intelligent. Neuroscientists have done hundreds of studies of musicians, particularly pianists, in which the research plainly shows that the brain, instead of using the familiar neural pathways (right brain going to left hand , left brain going to the right hand) has to work like crazy to create new neural pathways connecting the two hemispheres of the brain to one another. One of the accidental outcomes of that is that pianists, especially advanced pianists, are extremely intelligent as a group and tend to do well in every school subject. That being said, handedness is pretty hard-wired into us physiologically, and the old days of teachers forcing kids to do what was clearly unnatural for them was a terrible thing. .

I'm in my 60s and it was never an issue in my childhood. We used inkwells till I was half-way through primary school. I never got decent marks for handwriting because you can't help but smudge fountain-pen ink when you're left-handed, but nobody tried to convert me. When we moved to ballpoint pens most of the issues resolved, and my communication skills soared when I was given a typewriter at the age of 10. Of course I was taught various sports, instruments and crafts right-handed, but because righties have no imagination when it comes to putting themselves in lefties' shoes, not because they thought it was morally wrong to be left-handed. If I wanted to reverse everything and go properly left-handed they thought it "looked odd" but didn't really care. (Of course, no amount of persuasion is going to turn the baseball diamond around so you're facing first base when you bat true left-handed.)

R75 reminds me, there are a lot of ergonomic mouses but it's ridiculously hard to get one shaped for a left-hander. I find this especially offensive since Bill Gates is a lefty. R75, why are you "stuck with it"? You can easily change your settings to allow you to use the mouse left-handed.

It's worth noting there is a spectrum of handedness. Some people fall closer to the ambidextrous mid-point, whereas a few people are extremely one-sided. If you can't kick a ball with your right foot, use a microscope with your right eye, or perform even gross motor skills with reasonable accuracy with your right hand, you probably fall into this category. In a cinema, I will always gravitate to the right-hand side, so that my left eye ranges over more of the screen than my right.

On my Dad's side of the family, there's something of a preponderance of lefties, excepting my Dad and his seven siblings; after Grandma, it apparently skipped a generation, showing up again among the cousins with more than was statistically usual. I was one of them.

When she was little, Grandma endured a lot of abuse from parents and teachers, trying to force her to be right-handed. This made her an aggressive advocate for lefties among her grandkids. Coming to Texas to celebrate Thanksgiving with us one year (1970, I believe - the same year I had to evade a pair of teenagers/young adults trying to abduct me walking home from school, as I have related to the DL), she misinterpreted my Mom's table settings with silverware to the right of the plate as evidence of an effort to change my handedness. It wasn't, but still a confrontation broke out.

My Mom always sought to accommodate my lefthandedness, sending me to school with a pair of lefty scissors with the green rubber handles. My first grade teacher was having none of it; the scissors kept disappearing from the vinyl zipper bag in my binder. Eventually we realized it was the teacher doing it when I was out with the other kids at recess. There were a lot of issues with her, including her pulling my hair, slapping me around, and knocking me out of the desk. I've no idea what her actual issue with me was (the fact that I was lefthanded? Seems too extreme, but who knows?), but she concentrated her physical and verbal abuse on me, and threatened the other students that if they told anyone, she would do the same to them. Crazy bitch.

That particular school cultivated a weirdly abusive ethos; the principal was rumored to possess an electric paddle to be used on students. Indeed there was, in his office, hanging on the wall behind his desk, a wooden paddle with wires strung to plugs protruding from its edges. Looking back on it, I don't believe it was in any sense functional, but seemed to be just for show, but the fact that teachers and the principle were themselves responsible for propagating the rumor is very odd. My parents removed me from that school, and had to do a certain amount of negotiation with the ISD to permit me to attend a different elementary school.

The next one was just as backward and savage; on the first day, a little girl accused me of having said a bad word, and I was made to stand with my face to the wall in a corner at the front of the class for fifteen minutes, hands behind my back, holding a dime against the wall with my nose. If the dime fell to the floor, the teacher doubled the time. I didn't last a week there.

The third elementary school had to be the last; no more district shifting around. My second grade teachers were also quite abusive; lots of slapping, pinching, and hair-pulling. This bullshit seemed to stop when I reached the third grade, and I never experienced it again; it was as if there'd been a sea change in the way classes were conducted.

Sorry, I've digressed quite far from the subject of handedness, but I'm curious: did anyone else experience that kind of abuse in schools from the early 1970s?

by Anonymousreply 87May 25, 2024 7:42 AM

R87 Holy hell. was this in America? It sounds like the British schools in Pink Floyd’s The Wall. I went to public elementary in California during the early 70s, and the principal had a wooden paddle with holes cut into it, but it was used as more of a deterrent than a weapon. Only 2 in my class actually went under the paddle. Corporal punishment in Cali schools was banned in the 80s. Other than that, the principal and teachers were very nice and professional. I didn’t witness any abuse; left-handed students were allowed to be left-handed, and given the proper scissors. I think the overall culture of the school administration determines the type of teachers they hire, and the behavior they conform to. Sorry you ended up with sociopaths, PD.

I went to middle school with a girl who was truly ambidextrous. She could write and draw beautifully with both hands. But oftentimes when she was asked a question about anything, it would take her a minute to process and reply. I wonder if her left/right brains were warring with each other for an appropriate answer.
