A few years ago my family enjoyed the animated movie “The Croods” about a prehistoric family that spent every day fearfully trying to survive. Each morning the father rolled aside the rock from the front of their cave and reminded his family how dangerous it was outside. “Never not be afraid,” he admonished them. This is the same message we have heard from the media all our lives, isn’t it? But in journalism school I learned one of the media’s dirty little secret: fear sells.
