Stock-market crashes, terrorist attacks, and the dark side of “newsworthy” stories
Man bites dog. It is one of the oldest cliches in journalism, an acknowledgement of the idea that ordinary events are not newsworthy, whereas oddities, like a puppy-nibbling adult, deserve disproportionate coverage.
The rule is straightforward, but its implications are subtle. If journalists are encouraged to report extreme events, they guide both elite and public attitudes, leading many people, including experts, to feel like extreme events are more common than they actually are. By reporting on only the radically novel, the press can feed a popular illusion that the world is more terrible than it actually is.
Take finance, for example. Professional investors are fretting about the possibility of a massive stock-market crash, on par with 1987’s Black Monday. The statistical odds that such an event will occur within the next six months are about 1-in-60, according to historical data from 1929 to 1988. But when surveys between 1989 and 2015 asked investors to estimate the odds of such a crash in the coming months, the typical response was 1-in-10.
