We consider ourselves 'Progressed', ‘Cultured’, ‘Human Beings’, 'Civilised' and ‘Chosen’. The rest are ‘animals’. Or are we ... yet?
The Homo sapiens, like any other in the animal kingdom, have always been competing for survival. Our shaggy ape forefathers hunt, fight, kill, dominate and procreate on a regular basis. This enabled the survival of the fittest over the millenniums and in turn enabled our existence. Projecting dominance in the early ages was very important. And so was showing-off strength and being ruthlessness. These were some of the keys to survival. If not one could go hungry, get hurt, lose their breeding partner or worse lose their life. So back in the Stone Age time: One would kill & hunt when one wished; grabbed thy neighbour's food or partner if need be; kill if one didn't like that jerk; so in a way life was quite ‘simple’ and uncomplicated.
It was only a little later that SOCIETY enforced certain norms to maintain order and for the greater good. The unfortunate side of these norms in that just sometimes it acts like a cage and originality is lost. Anyways, civilizations didn’t change the Homo sapiens; How can what was conditioned over centuries be reversed in a shorter time? These species just found new ways to keep themselves as they were thus keeping alive the animistic subconscious of the past. Why else should there have been invasions, plunder, imperialism, tortures, roman circuses, wars, sports, inquisitions, genocides, apartheid and orgies? These are manifestations of the instincts of dominance, hunt, greed and competition … just given more ‘civilized’ labels.
Enter the space age. We look back to see how far we have come. We have progressed a lot ... but only externally. Internally still not far away. The time, across many millenniums since being civilised, has still not liberated us from our urges but rather only suffocated more souls in more claustrophobic mental cages. And so we keep alive our forefathers’ cravings: Carving for all things material (we never had enough) and craving for power (the shortcut to control the others). We are still not cleared off from the scars from the past. Behavioral patterns forged over time by our forefathers still lie dormant (until piqued) in our sub consciouses.
Unlike what we generally thought, these animal instincts from that very difficult past have not erased from the centuries of civilizing but only make us behave or act in very curious ways. Sometimes this programming from the past can manifest within an individual in very anti-social ways. Actually we shouldn't be surprised by the horrific reports of physical abuse, gang wars, rapes, psychopathic murders etc. that continue to this day.
We could argue that these heinous crimes are not committed by us but some minority others. Yes true, they are committed by active ‘program’ runners only. The rest of us passive runners only read or watch...while somebody else is doing it! Ever wondered why the newspapers and news channels gives all the obscene or disgusting details? It is because the public need or rather demand it. Movies enable us to (at least) watch simulated violence and perversion. Why is pornography so in vogue? Because it sells! Pornography gives us the option of relishing on ANY sexual perversion you can possibly think off without the guilt of actually performing it! Wondered why there were so many cabaret dances and rape scenes in Indian cinemas? Same reason: We wanted it.
And what are these reality shows after all? They are nothing but entertainment drawn from the exposure of the ‘normal’ side of people (mostly celebrities). And by the ‘normal’ we mean to expose the real or specifically the ugly side of human beings. Watch people’s vulnerability to the dark side … in real time: greed, lust, power, desperation etc. (Little do these people realize that their careers are almost doomed after their participation in one of these shows. Because once their real side is exposed they have lost the public’s fascination.)
Take the other example of the competition shows littering the channels. It is all about dominance again. C-O-N-T-R-O-L, as if we decide somebody’s fate or career. And what is it that we the audiences are most interested in here? Not the gleam on the faces of who wins but the defeat on the faces of who is out! A funny side of these types of shows is that the sponsors manage to get judges who are almost always third-grade in that field of expertise :-)

Consider even a simple everyday life matter as a joke. Realize that almost always a joke is centered on putting down one of the characters in the joke! Belittle, embarrass or ridicule. Funny isn’t it? Ever wondered why we crack jokes and laugh in the first place? It is our way of expressing our own superiority over the other. Baring teeth (while we laugh) is common in the animal kingdom also … for the same reason!
