Is that a fact-check?

Heisenberg’s principle can be crudely generalized (it’s the best I can do) as follows: An observer can change the nature of a thing or an event merely through the act of observation. Observation all by itself can become an intervention. Heisenberg was describing how reality works at the level of quantum mechanics, where a wave becomes a particle and vice versa depending on how it’s being measured. But it applies, too, at the level of political journalism, where reality is even stranger. There, facts can become interpretations, interpretations can become facts, and events of no significance can achieve an earthshaking importance simply by virtue of being pawed over by a large number of journalists.

A typical journalist, if he’s any good, insists at least theoretically on the iron divide between observer and participant. At its best the press corps sees itself as a squadron of Red Cross workers, wandering among the combatants in a battle zone and ensuring their own safety with a claim of strict neutrality. The Heisenberg Principle of Journalism puts the lie to all that. You see it at work whenever a news anchor announces that “this story just refuses to go away” or a headline writer insists that “questions continue to be raised” about the conduct of one hapless public figure or another.

The story refuses to go away, of course, because the anchor and his colleagues won’t let it; and the questions that continue to be raised are being raised by the headline writer and his editors. Reporters create more news than anybody, just by pretending they’re watching it unfold.

A lovely example from politics is a once meaningless event called the Ames straw poll, held in August every four years amid the rising heat and barnyard perfume of Iowa cow country.
