A mixture of both. Everytime someone justifys their fear they say things like "times are different" or "not the way things are today". When in reality everything is a lot the same as it was years ago we just have more media to tell us about it. This causes people to lock themselves in their homes, hover over their children until their teens, and live a life of constant worry. It's quite sad how many people don't even think they are living in fear but are. Fear of child being kidnapped, bombs, attacks on our country, financial collapse, and so on. While it is all possible and not a bad thing to prepare for, it certainly isn't worth constant fear.
