Some Little-Known Facts About Left-Handers

From their innovative minds to their political aspirations, there are plenty of great reasons to love lefties!

Lefties Hear Speeches Differently

People who are using their left hands when listening may more easily hear rapidly changing sounds than those who are using their right hands, according to a study from Georgetown University Medical Center. The researchers who conducted the study, presented at Neuroscience 2012, found that the left and right hemispheres of the brain specialize in different kinds of sounds — the left hemisphere, which controls the right hand, likes rapidly changing sounds like consonants, while the right hemisphere, which controls the left hand, likes slowly changing sounds, like syllables or intonation. According to the researchers, if you’re waving an American flag while listening to a presidential candidate, the speech will sound slightly different to you depending on whether you’re holding the flag in your left or right hand. The research could ultimately result in better treatment for stroke and language disorders.

Lefties Make Better Artists

Southpaws have been bragging about their creative clout for years. But is it true — does being left-handed mean you’re also more likely to be artistic or innovative?

According to research published in the American Journal of Psychology, there is some evidence that left-handed people have the upper hand in at least one creative facet — they’re better at divergent thinking, a method of idea generation that explores many possible solutions.

So to determine whether lefties were more likely to pursue creative careers than righties, the folks behind Left-Handers’ Club (a pro-leftie group dedicated to left-handed research and product development ) surveyed more than 2,000 left-handed, right-handed, and ambidextrous participants. What did they find? Lefties tended to find advantages and be drawn to careers in the arts, music, sports, and information technology fields.

We Vote for Left-Handers!

Doesn’t matter which way they swing politically: A surprisingly high percentage of recent U.S. presidents were on the left (in terms of handedness, of course).

The lengthy list of left-handed leaders includes four of the last seven commanders in chief — President Obama, Bill Clinton, George H.W. Bush, and Gerald Ford — as well as past presidents James Garfield and Harry Truman. In fact, there’s a rumor that Ronald Regan was born a leftie, but stringent schoolteachers converted him to a righty when he was young.

Should right-handed presidential wannabes fake it? Our penchant for left-handed POTUSes is probably pure coincidence; however, one recent Dutch study suggests that left-handed politicians actually have an advantage in televised debates. As a whole, people tend to associate right-handed gestures with “good” and left-handed gestures with “bad,” according to the researchers. Since television presents a mirror image, the lefties are the ones who appear to gesture with their right hand (the “good” hand).

Southpaws Will Beat You in Sports

Golf legend Phil Mickelson; tennis ace Rafael Nadal; boxing champ Oscar de la Hoya — did you know that a number of your favorite sports superstars are lefties?

Actually, left-handers may have the advantage in sports that involve two opponents facing each other, such as tennis, boxing, and baseball, according to an MSNBC review of the book The Puzzle of Left-Handednessby Rik Smits. The author chalks it up to the fact that left-handed athletes get a lot more opportunity to practice against right-handed opponents than vice versa (since there are so many more righties out there).

Now that’s a homerun for lefties.

Lefties Are Scaredy-Cats


If you’re a left-hander, that probably made you cringe. That’s because people who use their left hands tend to be more affected by fear than people who use their right hands, according to recent research presented at the annual conference of the British Psychology Society.

For the study, participants watched an eight-minute clip from the frightening film Silence of the Lambs. When asked to recall events from the segment, lefties were far more likely to show signs of post-traumatic stress disorder than righties, including giving fragmented descriptions and making more mistakes.

“It seems that after experiencing a fearful event, even on film, people who are left-handed had subtle behaviors that were like people suffering from post-traumatic stress disorder,” head researcher Carolyn Choudhary, PhD, told The Telegraph. Blame the brain: “It is apparent the two sides of the brain have different roles in PTSD and the right hand-side of the brain seems to be involved in fear. But we need to do more experiments to understand what exactly is going on here,” she said.

They Have Their Own Day!

international left-handers dayMark your calendar — August 13 is International Left-Hander’s Day.

Lefties across the globe will be celebrating the event, which was first launched in 1992 by the UK-based Left-Hander’s Club to increase awareness about the left-handed lifestyle. According to the group’s Web site, it’s a day “when left-handers everywhere can celebrate their sinistrality and increase public awareness of the advantages and disadvantages of being left-handed.”

How should you observe the occasion? Create a “leftie zone” — a designated area of personal space where everything must be done in a left-handed fashion, from your workspace setup to the way you use cutlery.

And that rule also extends to any right-handers who happen to enter the leftie zone.

Lefties Aren’t Going Anywhere

lefties are here to stayLeft-handers are the minority — so does that mean they’ll go extinct one day? Nah! In fact, some researchers believe that when it comes to survival of the fittest, lefties come out on top.

Here’s why: In man-on-man combat, using the left-hand is like throwing a curveball. “The fact that left-handers are less common means they have a surprise effect,” University of Montpellier researcher Charlotte Faurie told ABC News. To dig deeper, Faurie and her colleague Michel Raymond studied nine different primitive societies. In more violent societies, they found that lefties thrived (think southpaw slugger Rocky Balboa’s left hook).

Looks like the left hand has the upper hand after all.

Left-Handed Neanderthals Were the Minority, Too

Right-handed bias isn’t just a modern-day phenomenon. Turns out, we’ve been dominantly using our right hooks for more than 500,000 years.

University of Kansas researchers recently determined the handedness of ancient humans by studying — oddly enough! — their teeth. The study, which was published in the journal Laterality, found that when our great-great-great-great-(you get the point)-grandfathers would process animal hides, they would hold one side of the carcass in their hand and the other in their mouth. By locating the wear and tear on those prehistoric chompers, scientists were able to determine whether our prehistoric ancestors were using their left hand or right hand more dominantly

“All you need to have is a single tooth and you can tell, if our assumptions are right, if the individual is right- or left-handed,” study researcher David Frayer, Ph.D. told LiveScience. The results? “The fossils are just like humans in that we are mostly right-handed — and so were they.

Easily Embarrassed? Could Be Because You’re a Leftie

Aw shucks — lefties may get bent out of shape, but research shows they’re just a bunch of bashful self-observers.

When scientists from Abertay University in Scotland gave 46 lefties and 66 righties behavioral tests to measure their impulsiveness and personal restraint, the left-handers in the group more commonly agreed with statements like “I worry about making mistakes” and “Criticism or scolding hurts me quite a bit.” In fact, their answers left researchers believing that lefties tend to feel more inhibited, shy, and embarrassed than their right-handed counterparts.

“Left-handers are more likely to hesitate whereas right-handers tend to jump in a bit more,” lead researcher Lynn Wright, PhD, told BBC News.

Grrr! Left-Handers Get Angrier, Too

If you just can’t get let go of that spat you had with your right-handed pal (but he seemed to move on just fine), you may be able to blame it on your handedness: According to a small study published inThe Journal of Nervous and Mental Disease , lefties are more prone to having negative emotions. In addition, they seem to have a more difficult time processing their feelings.

Again, this seems to be related to the brain-hand connection. Compared to righties, left-handed participants in the study showed an imbalance in activity between the left and right hemispheres when trying to process their moodiness.

Your Handedness May Determine Your Health

left-hander factsOnly about 10 percent of the population is left-handed. Now mull over this: About 20 percent of people with schizophrenia dominantly use their left hands.

Coincidence? Probably not, say scientists, who have also found an increased risk for dyslexia, ADHD, and certain mood disorders in left-handed people, according to a recent Wall Street Journal article. Researchers are not exactly sure how to explain it, but many believe it’s related to how the brain is wired. Your noggin is divided into two halves — the left side and the right side. Most people (righties and lefties alike) rely on the brain’s left hemisphere for tasks like language functioning. However, about 30 percent of left-handed folks are either partial to the right hemisphere or have no dominant hemisphere at all. According to scientists, having one hemisphere dominate is much more efficient — and that’s why some left-handers are at an increased risk for learning impairments and brain disorders. (Who would’ve thunk it?!)

However, lefties may be in luck when it comes to other health conditions: A survey of more than 1.4 million participants, which was published in the journal Laterality, found that left-handers had lower rates of arthritis and ulcers.
