Paul Krugman: Sweet Little Lies

Four years into a war fought to eliminate a nonexistent threat, we all have renewed appreciation for the power of the Big Lie: people tend to believe false official claims about big issues, because they can’t picture their leaders being dishonest about such things.

But there’s another political lesson I don’t think has sunk in: the power of the Little Lie — the small accusation invented out of thin air, followed by another, and another, and another. Little Lies aren’t meant to have staying power. Instead, they create a sort of background hum, a sense that the person facing all these accusations must have done something wrong.
