"Why the “elsewhere effect”? One suspect is the media bias towards trouble. Good news is no news. News editors don’t give us many stories about good race relations, or about the 25-year drop in crime, or about the decrease in divorce. Instead, we get crime and conflict and a variety of other problems. Add to this the perpetual political campaign with opposition candidates tirelessly telling us what’s wrong. Given this balance of information, we can easily picture the larger society as a world in decline, a perilous world so different from the one we walk through every day."
