Pleased to meet you -- hope you guess my name

First, television does a lot of our predatory human research for us. American human beings are a slippery and protean bunch, in real life, as hard to get any kind of univocal handle on as a literary territory that's gone from Darwinianly naturalistic to cybernetically post-postmodern in eighty years. But television comes equipped with just such a syncretic handle. If we want to know what American normality is - what Americans want to regard as normal - we can trust television. For television's whole raison is reflecting what people want to see. It's a mirror. Not the Stendhalian mirror reflecting the blue sky and mud puddle. More like the overlit bathroom mirror before which the teenager monitors his biceps and determines his better profile. This kind of window on nervous American self-perception is just invaluable, fictionwise. And writers can have faith in television. There is a lot of money at stake, after all; and television retains the best demographers applied social science has to offer, and these researchers can determine precisely what Americans in 1990 are, want, see: what we as Audience want to see ourselves as. Television, from the surface on down, is about desire. Fictionally speaking, desire is the sugar in human food.

The second great thing is that television looks to be an absolute godsend for a human subspecies that loves to watch people but hates to be watched itself. For the television screen affords access only one way. A psychic ball-check valve. We can see Them; They can't see Us. We can relax, unobserved, as we ogle. I happen to believe this is why television also appeals so much to lonely people. To voluntary shut-ins. Every lonely human I know watches way more than the average U.S. six hours a day. The lonely, like the fictional, love one-way watching. For lonely people are usually lonely not because of hideous deformity or odor or obnoxiousness - in fact there exist today social and support groups for persons with precisely these features. Lonely people tend rather to be lonely because they decline to bear the emotional costs associated with being around other humans. They are allergic to people. People affect them too strongly. Let's call the average U.S. lonely person Joe Briefcase. Joe Briefcase just loathes the strain of the self-consciousness which so oddly seems to appear only when other real human beings are around, staring, their human sense-antennae abristle. Joe B. fears how he might appear to watchers. He sits out the stressful U.S. game of appearance poker.

But lonely people, home, alone, still crave sights and scenes. Hence television. Joe can stare at Them, on the screen; They remain blind to Joe. It's almost like voyeurism. I happen to know lonely people who regard television as a veritable deus ex machina for voyeurs. And a lot of the criticism, the really rabid criticism less leveled than sprayed at networks, advertisers, and audiences alike, has to do with the charge that television has turned us into a nation of sweaty, slack-jawed voyeurs. This charge turns out to be untrue, but for weird reasons.
