Few words have as great a hold on the contemporary imagination as ‘disinformation.’ Few words are as ubiquitous in contemporary discourse or as pervasive in political mud-slinging.

Disinformation, propaganda, lies: whatever you wish to call it, it’s the bogeyman of our age, a convenient repository for all our sins.
