I've never watched any "reality shows," partly because they never seemed interesting enough to get involved with and partly because I didn't think it would be particularly good for my soul to spend time enjoying cruelty. Also I haven't found much time to watch anything the past few years.
When I heard about the Survivor (ed: Big Brother) shows, and the "viewers voting them off" theme, I immediately thought of a simple way to make the shows more dramatic and viler(*): let the contestants have access to poll results. If one saw his numbers drop, he'd be more likely to indulge in dramatic stunts to get attention, especially if viewer suggestions were also available to them. The simplest ways to get attention are the old faithfuls sex and aggressiveness; and I'd guess those would become even more pronounced with such a model. And each week the sex and aggression would have to ratchet further to keep getting the required attention.
It is no part of my charge to increase the villainy of television, so I didn't advertise the idea. Sooner or later the producers would come up with it themselves.
Yesterday it occurred to me that we already have such an environment in the entertainment industries. The famous actors and singers have publicists who know fame is the key to raking in money; and who probably suggested some of the stunts that made the news. As I predicted, the result is ugly, and steadily getting worse. They're even interrupting (by collusion?) their own holy award ceremonies in order to get attention.
The point of diminishing returns is a moving target, because the culture gets more jaded. Even Polanski finds supporters. It can't go on forever, though--the personal price gets too high.
