I can't recall its name, but there's a phenomenon about this: You see media coverage of a topic you're very knowledgeable in and you know they're getting basic things wrong. (For example, that sub-4s happen within 10Ks.) But in areas where you don't have expert knowledge, you assume other parts of the same publication are more or less getting it right. For all we know, there are economists shaking their heads at the New Yorker's business and finance coverage, and then telling their friends, "Says here they now run sub-4 miles in 10Ks!"
Actually, this phenomenon sounds like the sort of thing Gladwell would write a book about!
You're referring to The Murray Gell-Mann Amnesia Effect, which Michael Crichton identified and named after the physicist friend of his. He defines it this way:
"Briefly stated, the Gell-Mann Amnesia effect works as follows. You open the newspaper to an article on some subject you know well. In Murray’s case, physics. In mine, show business. You read the article and see the journalist has absolutely no understanding of either the facts or the issues. Often, the article is so wrong it actually presents the story backward-reversing cause and effect. I call these the “wet streets cause rain” stories. Paper’s full of them.
In any case, you read with exasperation or amusement the multiple errors in a story-and then turn the page to national or international affairs, and read with renewed interest as if the rest of the newspaper was somehow more accurate about far-off Palestine than it was about the story you just read. You turn the page, and forget what you know.
That is the Gell-Mann Amnesia effect. I’d point out it does not operate in other arenas of life. In ordinary life, if somebody consistently exaggerates or lies to you, you soon discount everything they say. In court, there is the legal doctrine of falsus in uno, falsus in omnibus, which means untruthful in one part, untruthful in all.
But when it comes to the media, we believe against evidence that it is probably worth our time to read other parts of the paper. When, in fact, it almost certainly isn’t. The only possible explanation for our behavior is amnesia."
