The Surprising Link Between Creativity and Schizophrenia

Creative people—or at least those with degrees in creative fields—have a 90 percent higher chance of being diagnosed with schizophrenia than people working in non-creative fields, according to a new study published in The British Journal of Psychiatry. It also found that artistic types are 62 percent more likely to have bipolar disorder, and 39 percent more likely to have depression.

Researchers at King's College London mined a registry of 4.5 million people in Sweden and found links between those who had studied an artistic field (like music or art) and those who had been hospitalized for schizophrenia, bipolar disorder, or depression, compared to the general population. Schizophrenia occurs in about 1 percent of the general population.

But that doesn't mean that creativity causes mental illness, as Big Think points out. As scientists like to say, correlation does not equal causation. In the current study, the researchers say the link can be explained by the fact that the brains of creative people may function differently. "Creativity often involves linking ideas or concepts in ways that other people wouldn't think of," James MacCabe, the lead researcher, told New Scientist. "But that's similar to how delusions work—for example, seeing a connection between the color of someone's clothes and being part of an MI5 [UK security service] conspiracy."

This isn't the first study to examine the relationship between creativity and mental illness—and not everyone is convinced that such a relationship exists—but the King's College researchers say the huge scope of their study is different. "High-quality epidemiological evidence has been lacking," they write.

A similar study of the Swedish population from 2011 found a link between bipolar disorder and those working in a creative field, but found no link for schizophrenia or depression. And in 2015, a controversial study by the CEO of a biological research company purportedly found that people working in creative fields were more likely to carry the genetic variants for mental illness. However, those variants only had a tiny effect on creativity—less than 1 percent.

Yes, You Have Too Many Tabs Open on Your Computer—and Your Brain is Probably to Blame

If you’re anything like me, you likely have dozens of tabs open at this very moment. Whether it’s news stories you mean to read later, podcast episodes you want to listen to when you have a chance, or just various email and social media accounts, your browser is probably cluttered with numerous, often unnecessary tabs—and your computer is working slower as a result. So, why do we leave so many tabs open? Metro recently provided some answers to this question, which we spotted via Travel + Leisure.

The key phrase to know, according to the Metro's Ellen Scott, is “task switching,” which is what our brains are really doing when we think we're multitasking. Research has found that humans can't really efficiently multitask at all—instead, our brains hop rapidly from one task to another, losing concentration every time we shift our attention. Opening a million tabs, it turns out, is often just a digital form of task switching.

It isn't just about feeling like we're getting things done. Keeping various tabs open also works as a protection against boredom, according to Metro. Having dozens of tabs open allows us to pretend we’re always doing something, or at least that we always have something available to do.

It may also be driven by a fear of missing information—a kind of “Internet FOMO,” as Travel + Leisure explains it. We fear that we might miss an important update if we close out of our social media feed or email account or that news article, so we just never close anything.

But this can lead to information overload. Even when you think you're only focused on whatever you're doing in a single window, seeing all those open tabs in the corner of your eye takes up mental energy, distracting you from the task at hand. Based on studies of multitasking, this tendency to keep an overwhelming number of tabs open may actually be altering your brain. Some studies have found that "heavy media multitaskers"—like tab power users—may perform worse on various cognitive tests than people who don't try to consume media at such a frenzied pace.

More simply, it just might not be worth the bandwidth. Just like your brain, your browser and your computer can only handle so much information at a time. To optimize your browser's performance, Lifehacker suggests keeping only nine tabs open—at most—at one time. With nine or fewer tabs, you're able to see everything that's open at a glance, and you can use keyboard shortcuts to navigate between them. (On a Mac, you can press Command + No. 1 through No. 9 to switch between tabs; on a PC, it's Control + the number.)

That said, there are, obviously, situations in which one might need many tabs open at one time. Daria Kuss, a senior lecturer specializing in cyberpsychology at Nottingham Trent University, tells Metro that “there are two opposing reasons we keep loads of tabs open: to be efficient and ‘create a multi-source and multi-topic context for the task at hand.’” Right now, for example, I have six tabs open to refer to for the purposes of writing this story. Sometimes, there's just no avoiding tabs.

In the end, it's all about accepting our (and our computers') limitations. When in doubt, there’s no shame in shutting down those windows. If you really want to get back to them, they're all saved in your browser history. If you're a relentless tab-opener, there are also browser extensions like OneTab, which collapses all of your open tabs into a single window of links for you to return to later.

Will the Sun Ever Stop Shining?

Viktor T. Toth:

The Sun will not stop shining for a very, very long time.

The Sun, along with the solar system, is approximately 4.5 billion years old. That is about one-third the age of the entire universe. For the next several billion years, the Sun is going to get brighter. Perhaps paradoxically, this will eventually result in a loss of carbon dioxide in the Earth’s atmosphere, which is not good news; It will eventually lead to the death of plant life.

Within 2.5 to 3 billion years from now, the surface temperature of the Earth will exceed the boiling point of water everywhere. Within about about 4 to 5 billion years, the Earth will be in worse shape than Venus today, with most of the water gone, and the planet’s surface partially molten.

Eventually, the Sun will evolve into a red giant star, large enough to engulf the Earth. Its luminosity will be several thousand times its luminosity at present. Finally, with all its usable nuclear fuel exhausted and its outer layers ejected into space, the Sun’s core will settle down into the final stage of its evolution as a white dwarf. Such a star no longer produces energy through nuclear fusion, but it contains tremendous amounts of stored heat, in a very small volume (most of the mass of the Sun will be confined to a volume not much larger than the Earth). As such, it will cool very, very slowly.

It will take many more billions of years for the Sun to cool from an initial temperature of hundreds of thousands of degrees to its present-day temperature and below. But in the end, the remnant of the Sun will slowly fade from sight, becoming a brown dwarf: a cooling, dead remnant of a star.
