Other evidence supports that theory. Here's a look at some of the most common facts about being left-handed, and what it might really mean for your health.Scientists aren't exactly sure why some people are left-handed, but they know that genes are responsible about 25% of the time, says Yeo. But if you're left-handed, you might not think the same way as righties, according to a 2009 Stanford University study. "It's an interesting contrast to views from a few decades ago or before, that stereotyped left-handers as somehow mentally or morally inferior," she says. Left-handedness does tend to run in families, he says, "but noticeably less than other inherited traits, like height or intelligence." But several studies since have debunked those claims, and scientists now generally accept that being a rightie or a leftie has zero effect on lifespan.A 2007 Scottish study found that left-handers were more likely to display symptoms of post-traumatic stress disorder after watching clips from a scary movie. “The stereotype [that left-handers are mentally or morally inferior] doesn’t reflect reality,” study author Gina Grimshaw, PhD, director of the Cognitive and Affective Neuroscience Laboratory at the University of Wellington in New Zealand told Since most right-handed people use the left hemisphere of the brain to process language, that must mean that left-handed people think with the right side of the brain, right?

The brains and bodies of lefties may operate differently than those of right-handed people (and in mixed-handed people, who may have different dominant hands for different tasks).
According to British media reports, he'd like his toddler son, George, to carry on the tradition. Dr. Grimshaw found that while 98 percent of righties are left-brained, so are 70 percent of lefties. In one 2008 Swedish study of moms and their 5-year-old children, women who were depressed or stressed during their pregnancies were more likely to have mixed- or left-handed kids.
Easily Embarrassed? "There is no reason to believe that it is associated with excessive alcohol consumption or risky drinking," the authors wrote.Whether the cognitive, mental, and physical differences lefties have from righties actually make a real-world difference in people's lives is still up for debate—but a 2014 Harvard study suggests that they might. “Left-handed people have to think flexibly and come up with ways to use those tools and navigate.”Another common lore is that left-handed people tend to be more introverted than righties. While the two seem completely unrelated, Yeo says that both could be the result of something affecting a fetus in early development. Research has not been able to back up most of these claims, says Grimshaw, and that theory has been largely debunked. "We know that other physical vulnerabilities, like low birth weight and prenatal head circumference, can predict later health issues," he says. Fuse via Getty Images. That rumor may come from a 1995 study that found left-handed men tended to engage in more "divergent thinking" than right-handed men—meaning they explore more options to solve a problem than the ones readily available. In a 2007 study published in the British Journal of Cancer, researchers found that left-handers had a higher risk of breast cancer than right-handers, especially for cancer that occurred after menopause. Just 10 percent of the population is left-handed. There are many myths about the differences between righties and lefties, yet most evidence … “When you look at actual creative achievements in one’s lifetime, the evidence is not strong for association with left-handedness,” Ronald Yeo, PhD, professor of psychology at the University of Texas-Austin told Six of the last 12 U.S. presidents have been lefties, but that’s only considered presidential trivia, not a qualification for the job. "There's a grain of truth to the creativity idea, but when you look at actual creative achievements in one's lifetime, the evidence is not strong for association with left-handedness," says Yeo.Southpaws also have a reputation for being introverted and artsy, says Grimshaw. About 98% of right-handers are left-brained, she says, but so are about 70% of left-handers. A 1995 study found left-handed men tended to think more creatively when problem-solving; however, there was no difference in the thinking between female righties and lefties. Surya is a leading manufacturer of high-quality, fashion-forward area rugs and coordinating home accessories. But a 2013 New Zealand study found no differences across any of the five personality measures tested between right-handers and left-handers. If you happened to hold a pencil with your left hand, you’d be whipped into submission, with right wing teachers linking lefties to to Satan himself. Both findings could be due to the fact that non-righties are more likely to have unusual brain lateralization, which could affect the way their brains process fear and anger.Many small studies have suggested that lefties drink more than righties, but scientists weren't sure why. Only about 30% are right-brained or bilateral-brained (in which both halves are equally capable).
When finally facing a southpaw, lefties can easily adjust—but righties are at a double disadvantage.
In violent societies, researchers theorize, left-handers benefit from their unexpected left hook.Left-handed people are often credited with being more creative than righties, but that's a hard thing to measure, says Yeo. Researchers studied a small group of individuals from an outpatient psychiatric clinic and found that 40 percent of those with schizophrenia or schizoaffective disorder were left-handed. Perhaps because Simpson creator Matt Groening is a leftie, too. And we certainly shouldn't worry about lefties' chances of success: After all (as of 2015), five of our last seven U.S. presidents have been either left- or mixed-handed.Barack Obama is the latest in a string of left-handed U.S. presidents. The six suspects are Paulus Suryanta Ginting (Surya Anta), Isay Wenda, Charles Kosay, Ambrosius Mulait, Anes Danoo Tabuni and Arina … They found that left-handers did tend to drink more often, but mainly because they were "less likely to drink rarely (less than once a month) or not at all."
