Credulity does not suit journalists or our audiences. We’ve moved from believing something because “I read it in the paper” to “I heard it on the radio” to “I saw it on the Internet.” It’s never so dangerous as when a comment or story is credible. It makes sense. It’s the kind of thing that What’s His Name would say. Long before the Internet, people were inventing or repeating quotes and attributing them to famous people to add authority to their arguments.
