In
the past few decades, the fortunate among us have recognized the hazards of
living with an overabundance of food (obesity, diabetes) and have started to
change our diets. But most of us do not yet understand that news is to the mind
what sugar is to the body. News is easy to digest. The media feeds us small
bites of trivial matter, tidbits that don't really concern our lives and
don't require thinking. That's why we experience almost no saturation. Unlike
reading books and long magazine articles (which require thinking), we can
swallow limitless quantities of news flashes, which are bright-colored candies
for the mind. Today, we have reached the same point in relation to information
that we faced 20 years ago in regard to food. We are beginning to recognize
how toxic news can be.
News misleads. Take the following event. A car drives over a bridge,
and the bridge collapses. What does the news media focus on? The car. The
person in the car. Where he came from. Where he planned to go. How he
experienced the crash (if he survived). But that is all irrelevant. What's
relevant? The structural stability of the bridge. That's the underlying risk
that has been lurking, and could lurk in other bridges. But the car is flashy,
it's dramatic, it's a person (non-abstract), and it's news that's cheap to
produce. News leads us to walk around with the completely wrong risk map in our
heads. So terrorism is over-rated. Chronic stress is under-rated. Kenyan Politicians
are over-rated. Teachers are under-rated.
We
are not rational enough to be exposed to the press. Watching a building being
blown off by terrorists on television is going to change your attitude
toward that risk, regardless of its real probability. If you think
you can compensate with the strength of your own inner contemplation, you
are wrong. Bankers and economists – who have powerful incentives to compensate
for news-borne hazards – have shown that they cannot. The only solution: cut
yourself off from news consumption entirely.
News is irrelevant. Out of the approximately 10,000 news stories you have read
in the last 12 months, name one that – because you consumed it – allowed you to
make a better decision about a serious matter affecting your life, your career
or your business. The point is: the consumption of news is irrelevant to you.
But people find it very difficult to recognize what's relevant. It's much
easier to recognize what's new. The relevant versus the new is the fundamental
battle of the current age. Media organizations want you to believe that news
offers you some sort of a competitive advantage. Many fall for that. We get
anxious when we're cut off from the flow of news. In reality, news consumption
is a competitive disadvantage. The less news you consume, the bigger the
advantage you have.
News has no explanatory power. News items are bubbles popping on the surface of a
deeper world. Will accumulating facts help you understand the world? Sadly, no.
The relationship is inverted. The important stories are non-stories: slow,
powerful movements that develop below journalists' radar but have a
transforming effect. The more "news factoids" you digest, the less of
the big picture you will understand. If more information leads to higher economic
success, we'd expect journalists to be at the top of the pyramid. That's not
the case.
News is toxic to your body. It constantly triggers the limbic system. Panicky stories
spur the release of cascades of glucocorticoid (cortisol). This deregulates
your immune system and inhibits the release of growth hormones. In other words,
your body finds itself in a state of chronic stress. High glucocorticoid levels
cause impaired digestion, lack of growth (cell, hair, bone), nervousness
and susceptibility to infections. The other potential side-effects include
fear, aggression, tunnel-vision and desensitisation.
News increases cognitive errors. News feeds the mother of all cognitive
errors: confirmation bias. In the words of Warren Buffett: "What the human
being is best at doing is interpreting all new information so that their prior
conclusions remain intact." News exacerbates this flaw. We become prone to
overconfidence, take stupid risks and misjudge opportunities. It also
exacerbates another cognitive error: the story bias. Our brains crave stories
that "make sense" – even if they don't correspond to reality. Any
journalist who writes, "The market moved because of X" or "the
company went bankrupt because of Y" is an idiot. I am fed up with this
cheap way of "explaining" the world.
News inhibits thinking. Thinking requires concentration. Concentration requires
uninterrupted time. News pieces are specifically engineered to interrupt you.
They are like viruses that steal attention for their own purposes. News makes
us shallow thinkers. But it's worse than that. News severely affects memory.
There are two types of memory. Long-range memory's capacity is nearly infinite,
but working memory is limited to a certain amount of slippery data. The path
from short-term to long-term memory is a choke-point in the brain, but anything
you want to understand must pass through it. If this passageway is disrupted,
nothing gets through. Because news disrupts concentration, it weakens
comprehension. Online news has an even worse impact. In a 2001 study two scholars in Canada showed
that comprehension declines as the number of hyperlinks in a document
increases. Why? Because whenever a link appears, your brain has to at least
make the choice not to click, which in itself is distracting. News is an
intentional interruption system.
News works like a drug. As stories develop, we want to know how they continue. With
hundreds of arbitrary storylines in our heads, this craving is increasingly
compelling and hard to ignore. Scientists used to think that the dense
connections formed among the 100 billion neurons inside our skulls were largely
fixed by the time we reached adulthood. Today we know that this is not the
case. Nerve cells routinely break old connections and form new ones. The more
news we consume, the more we exercise the neural circuits devoted to skimming
and multitasking while ignoring those used for reading deeply and thinking with
profound focus. Most news consumers – even if they used to be avid book readers
– have lost the ability to absorb lengthy articles or books. After four, five
pages they get tired, their concentration vanishes, they become restless. It's
not because they got older or their schedules became more onerous. It's because
the physical structure of their brains has changed.
News wastes time. If you read the newspaper for 15 minutes each morning,
then check the news for 15 minutes during lunch and 15 minutes before you go to
bed, then add five minutes here and there when you're at work, then count
distraction and refocusing time, you will lose at least half a day every week.
Information is no longer a scarce commodity. But attention is. You are
not that irresponsible with your money, reputation or health. Why give
away your mind?
News makes us passive. News stories are overwhelmingly about things you cannot
influence. The daily repetition of news about things we can't act upon makes us
passive. It grinds us down until we adopt a worldview that is pessimistic, desensitized,
sarcastic and fatalistic. The scientific term is "learned
helplessness". It's a bit of a stretch, but I would not be surprised
if news consumption, at least partially contributes to the widespread disease
of depression.
News kills creativity. Finally, things we already know limit our creativity. This
is one reason that mathematicians, novelists, composers and entrepreneurs often
produce their most creative works at a young age. Their brains enjoy a wide,
uninhabited space that emboldens them to come up with and pursue novel ideas. I
don't know a single truly creative mind who is a news junkie – not a writer,
not a composer, mathematician, physician, scientist, musician, designer,
architect or painter. On the other hand, I know a bunch of viciously
uncreative minds who consume news like drugs. If you want to come up with old
solutions, read news. If you are looking for new solutions, don't.
Society
needs journalism – but in a different way. Investigative journalism is
always relevant. We need reporting that polices our institutions and uncovers
truth. But important findings don't have to arrive in the form of news. Long
journal articles and in-depth books are good, too. If you find this article too
long to go through, you are a victim of news….
