There's one distinct benefit to unplugging, however briefly, from the political news cycle: it may make you more positive about the problems of the world in general, and human nature specifically. This isn't just a hopeful idea; it's a genuine scientific theory. The Mental Health Foundation, a UK-based charitable organization, noted in February 2017 that taking time out of a news cycle dominated by Trump and Brexit is likely necessary for maintaining mental health, because of the theories of a Hungarian-American academic who changed the way we think about mass communication:
"When George Gerbner, a pioneer researcher on the effects of television on society, established his 'cultivation theory,' he coined the term 'Mean World Syndrome' to describe what he had found. The more time people spent watching the news or 'living in the television world,' the more likely they were to believe that the world is more dangerous than it actually is. Gerbner argued that people who watch more television tended to think of the world as an intimidating and unforgiving place and harbored more fear and anxiety about the world around them."
The "mean world syndrome" is bolstered by the the fact that humans have what's known as a natural "negativity bias." Psychological research has indicated that humans tend to show what researchers in 2008 called "the propensity to attend to, learn from, and use negative information far more than positive information." If you look at this from an evolutionary perspective, it makes sense. To keep ourselves alive in an environment full of potential threats, it was valuable for humans to evolve to "pay more attention to negative stimuli," so that we gave more of our mental resources to potential mountain lions than pretty flowers.
When it comes to our news consumption, this works out in interesting ways. A 2016 study, for instance, looked at our tendency to do "multitasking" when it comes to absorbing news, switching our attention between television news and a "second screen," like Twitter. Negative tweets seen simultaneously alongside news broadcasts drew more attention than positive tweets, but they didn't detract away from news viewing overall. And in 2014, scientists found that even though people tended to say they preferred good news, they were much more likely to select depressing news stories.
The "mean world syndrome" theory isn't universally believed, though. The 2014 scientists thought that perhaps people are drawn to bad news through an inherent positive belief in the world, in the hope that faith in humanity will be restored or a solution will present itself. Either way, unplugging for a while may be a good thing for your hope for the future of the world in general.
