Are Left-Handed People Really More Creative?

The left-handed brand has come a long way in the last few decades. The majority of people no longer assume that southpaws are tools of Satan, alight with hellfire. Today’s lefties are surrounded by a far more benevolent glow. We associate left-handedness with intelligence, out-of-the-box thinking, and artistic talent. But are these flattering generalizations backed up by science? Does being left-handed really make you more creative? 

The answer to that is a definitive … maybe.

Scientists have been chipping away at the peculiarities of left-handedness, which occurs in about 10 percent of the population, for a long time. They’ve looked into the purported links between left-handedness and things like mental illness, faulty immune systems, and criminal behavior. They’ve studied whether lefties are better at problem-solving, and if they’re more likely to die young. From all these studies on left-handedness, we can conclude one thing, and one thing alone: science is complicated. 

A handful of studies have found a link between left-handedness and creativity, conferred (some think) by the fact that left-handed folks constantly have to adjust to a right-handed world. Other studies found no link at all. 

Some researchers conclude that lefties are no smarter than righties, while others say that left-handedness comes with a clear intellectual advantage. Is there really a left-handed personality? Are lefties more prone to schizophrenia and learning disabilities? That depends on who you ask. 

But "Are lefties different?" might not even be the right question. Over the last few years, a number of studies have concluded that it’s not which hand is dominant that matters—it’s the degree of dominance. According to researchers, very few people are truly entirely left- or right-handed; it’s more of a spectrum. We use our left hands for some things and our right hands for other tasks. 

These experiments have found that people toward the middle of the spectrum are more flexible thinkers. They seem to be more empathetic and better able to view things from other people’s perspectives. When considering the risks and benefits of any given decision, inconsistent-handed people (as researchers call them) are more likely to focus on the risks, whereas people at the outer edges of the handedness spectrum pay more attention to potential benefits. They may even sleep differently. It seems we’ve been aiming our stereotypes a little too far to the left.

But who knows? This is ever-changing, constantly evolving science. If you’re a lefty who enjoys feeling superior, we’re not going to tell you to tone it down. For all we know, you could be right.

Has An Element Ever Been Removed From the Periodic Table?

Barry Gehm:

Yes, didymium, or Di. It was discovered by Carl Mosander in 1841, and he named it didymium from the Greek word didymos, meaning twin, because it was almost identical to lanthanum in its properties. In 1879, a French chemist showed that Mosander’s didymium contained samarium as well as an unknown element. In 1885, Carl von Weisbach showed that the unknown element was actually two elements, which he isolated and named praseodidymium and neodidymium (although the di syllable was soon dropped). Ironically, the twin turned out to be twins.

The term didymium filter is still used to refer to welding glasses colored with a mixture of neodymium and praseodymium oxides.

One might cite as other examples various claims to have created/discovered synthetic elements. Probably the best example of this would be masurium (element 43), which a team of German chemists claimed to have discovered in columbium (now known as niobium) ore in 1925. The claim was controversial and other workers could not replicate it, but some literature from the period does list it among the elements.

In 1936, Emilio Segrè and Carlo Perrier isolated element 43 from molybdenum foil that had been used in a cyclotron; they named it technetium. Even the longest-lived isotopes of technetium have a short half-life by geological standards (millions of years) and it has only ever been found naturally in minute traces as a product of spontaneous uranium fission. For this reason, the original claim of discovery (as masurium) is almost universally regarded as erroneous.

As far as I know, in none of these cases with synthetic elements has anyone actually produced a quantity of the element that one could see and weigh that later turned out not to be an element, in contrast to the case with didymium. (In the case of masurium, for instance, the only evidence of its existence was a faint x-ray signal at a specific wavelength.)

Can You Ever Truly Lose Your Accent?

You may be able to pull off a Spanish accent when showing off your Antonio Banderas impression, but truly losing your native accent and replacing it with a new one is a lot harder to do. The way you speak now will likely stick with you for life.

According to Smithsonian, our accent develops as early as 6 months old—accents being the pronunciation conventions of a language shaped by factors like region, culture, and class. When a baby is learning the words for nap and dad and play, they're also learning how to pronounce the sounds in those words from the people around them. Newborn brains are wired to recognize and learn languages just from being exposed to them. By the time babies start talking, they know the "right" pronunciations to use for their native language or languages.

As you get older, your innate understanding of foreign accents and languages gets weaker. If you're an English speaker raised in Boston, you may think that the way someone from Dallas speaks English sounds "wrong" without being able to articulate what it is that makes them sound different. This is why pulling off a convincing foreign accent can be so difficult, even if you've heard it many times before.

Around age 18, your ability to learn a second language takes a steep nosedive. The same may be true with your ability to speak in a new accent. If you immerse yourself in a foreign environment for long enough, you may pick up some ticks of the local accent, but totally adopting a non-native accent without making a conscious effort to maintain it is unlikely as an adult.

There is one exception to this rule, and that's Foreign Accent Syndrome. Following a head injury or stroke, some people have reported suddenly speaking in accents they didn't grow up using. The syndrome is incredibly rare, with only 100 people around the world having been diagnosed with it, and medical experts aren't sure why brain injuries cause it. But while patients may be pronouncing their words differently, they aren't exactly using foreign accents in the way most people think of them; the culprit may be subtle changes to muscle movements in the jaw, tongue, lips, and larynx that change the way patients pronounce certain vowels.
