I was surprised by the effect it had on me. I'd assumed that my skepticism and media literacy would inoculate me against such distortions. But I soon found myself reflexively questioning every headline. It wasn't that I believed Trump and his boosters were telling the truth. It was that, in this state of heightened suspicion, truth itself-about Ukraine, impeachment, or anything else-felt more and more difficult to locate. With each swipe, the notion of observable reality drifted further out of reach.
What I was seeing was a strategy that has been deployed by illiberal political leaders around the world. Rather than shutting down dissenting voices, these leaders have learned to harness the democratizing power of social media for their own purposes-jamming the signals, sowing confusion. They no longer need to silence the dissident shouting in the streets; they can use a megaphone to drown him out. Scholars have a name for this: censorship through noise.
