There’s no hard scientific evidence that handedness had anything to do with their leadership skills. Browse our large selection of contemporary, traditional, designer and … While the two seem completely unrelated, Yeo says that both could be the result of something affecting a fetus in early development.
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. (It was also once thought that all left-handed people started out as twins, and that their rightie siblings died in the womb.) One really interesting factoid that I picked up was from a scientist who believed that left handed people tended to be more independent as a result of having to adapt to a world which is largely built for right handed individuals. "Society tends to associate the left side of something with the bad ("two left feet"), and the right side with the good ("my right-hand man").
The extrapolation is that there must be something common between these individuals who are elected and successful, one being their handedness,” says Elizabeth Ochoa, PhD, chief psychologist at Mount Sinai-Beth Israel.“There’s an idea that left-handed people are more intelligent, but that’s not so,” says Dr. Ochoa. There are many myths about the differences between righties and lefties, yet most evidence …
"Handedness seems to be determined very early on in fetal development, when a lot of other things about your future are being determined as well," says Ronald Yeo, PhD, professor of psychology at the University of Texas-Austin. As for the left-handed patients, 94% of them had these movements. "For left-handed people, implicitly, they think good stuff is on the left and bad stuff is on the right, even though consciously, explicitly, everything in language and culture is telling them the exact opposite," the study's lead author said in a press release. "And if they turn out to be left-handed, I won't worry, but will keep an eye out for some of these other things. Lefties may get bent out of shape, but research shows they're just a bunch of bashful self-observers. Surya is a leading manufacturer of high-quality, fashion-forward area rugs and coordinating home accessories. Left-handedness does tend to run in families, he says, "but noticeably less than other inherited traits, like height or intelligence." There are some things that all super creative people have in common; being left-handed isn’t one of them. 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. "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.
"However, we really don't know much about the brains of mixed-handers, because we've been so focused on the left-handers," she says. So a 2011 study published in the British Journal of Psychological Health examined the issue on a large scale, using self-reported data from more than 27,000 people. "Most left-handers seem to have similar language processing to right-handers," Grimshaw says. Find out what's happening in the world as it unfolds.With just 10% of the population being left-handed, it can be easy for everyone else to forget we're living in a right-handed world. Other evidence supports that theory. Lefties may, however, think differently.
"When people ask me for the takeaway message, I tell them that it makes me pay a little extra attention to my kids as they develop their handedness," Goodman said in a press release. Aw-shucks. “The world is not a left-handed-friendly place—utensils, scissors, and other items of daily use are designed for the right-handed person,” says Dr. Ochoa. Other studies have found that non-right-handers experience more negative emotions. "They're forced to engage in an asymmetrical battle for which they're poorly prepared, against an opponent who's a dab hand at dealing with this type of asymmetry," he writes.In a 2005 French study, researchers found that southpaws made up just about 3% of the population in the most peaceful primitive societies, but 27% in the most warlike ones. 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.
