Urbanization started a self-reinforcing circle of hatred. Evolutionarily, people are predisposed to hear good news about their friends and close neighbors, and bad news about everyone else. This is why rumors are generally wicked.

In large cities, as opposed to parochial towns, there are no neighbors: residents are alien to each other even if they live next door. Thus, they enjoy bad news. This can be seen in the difference between local and national press. Small-town papers are usually friendly and run good-spirited stories of local interest. National media are soaked with blood, concentrating overwhelmingly on bad, violent news and discontent. A city dweller cannot read small-town newspapers, not because local journalists are so bad, but because they write nice things about people who are alien to him.

Randomly chosen people likely share fears and hatreds; they are rather unlikely to share goodwill toward a particular object. Millions of subscribers of major newspapers do not love same things, but are united in fear and hatred. Media give them what they want.

Sometimes media create artificial neighbors. Starving Africans are pictured on TV so often that they have practically become members of American households. Such quasi-neighbors inspire charity and other support, but even in regards to them Americans prefer bad news: of famine, drought, and war. Certainly every TV viewer claims to feel extreme regret over these events, but it is only bad events that he or she is interested in. No one cares how many African children are saved by aid; everyone wants to know how many have died without it.

Pandering to popular tastes, media deliver bad news about aliens, both those far away physically and psychologically. War in Africa and a knife attack downtown are both welcome news. The more recognizable are the participating aliens, the more interesting are the news stories about them. Bad news about Israel is more interesting than news about Saudi Arabia, and a particularly cruel downtown murder is more interesting than war in Israel.

When people are fed bad news, they become still more hysterical and grim in their outlook. They become more wary of their next-door aliens. Media, consequently, deliver ever-grimmer news.
Large cities exacerbate fear and hatred.
