When we presume to lie for the benefit of others, we have decided that we are the best judges of how much they should understand about their own lives—about how they appear, their reputations, or their prospects in the world.

The lies of conspiracy theorists raise doubts about the honesty of whistle-blowers, even when they are telling the truth. 17 Lies are the social equivalent of toxic waste: Everyone is potentially harmed by their spread.
