From Texas Standard:
You probably remember playing "telephone" as a kid. You sit in a circle, pass a message around, and see how it comes out on the other end. But during an emergency, when new information comes fast, lives are at stake, and normal lines of communication get disrupted – two cans on a string might be a better analogy than a phone. During Hurricane Harvey, information was scarce, and what people did find out was often wrong, and fueled by fear – creating a high-pressure version of the telephone game.
