“Echo” has taken on a new meaning for me now that we have the Internet. I noticed the phenomenon especially, excruciatingly, during the recent election cycle where a news entity (legit or otherwise) would pick up a story or a Tweet and write about it and then another would pick up that story and write about the story and then another would pick up the story about the story and post THAT. Echoes. Dangerous echoes because repetition is one way of persuading people without needing facts or an argument. We are designed so that if we see something everywhere, we think it’s important, or, worse; we think it’s true just because everyone is saying it.
