Rolf Dobelli skriver i The Guardian om, hvordan nyhedsformidling er en slags kognitionenens fast food, der fylder dig med en lind strøm af trivielle kendsgerninger og sidste-minuts-opdateringer, der stjæler din opmærksomhed, forhindrer dig i at se det store billede og forvirrer mere end godt er.
Jeg har ikke selv set TV-avis i årevis og åbner meget sjældent en avis, så selv om man altid kan diskutere det enkelte argument, har han nogle særdeles vigtige pointer:
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.
