I do not understand the argument about the bell and the dogs.
People are very easily trained and manipulated, the problem is that dogs understand only very basic things (they like food. bell means food. go get food). Humans need a driving force. Their brains are more complicated and there is a sense of entitlement to free will and independance. It's not because the person is not hungry that they choose not to eat, it's because the person is aware that another force is trying to control them and they would revel in resistance. If this controlling factor does not exist, yes, people are trained like dogs.
Look at your daily routine and compare it to mine. I was never adheared to strict standards in hygeine or cleanliness. I brush my teeth when I remember, maybe once every three days. I bathe when I get a chance, unless I'm unbareably dirty. I almost never clean up around the house and I will put off dishes until there are none left. Parents train kids to do routines for a reason: It's a good idea. When they grow up, they won't be bothered by taking care of themselves of tiding up.
I've been at work now for some time and I am trained. When I close my eyes at night, sometimes I hear the fryer's timers going off. I sometimes get a sense of anxiety of the managers freaking out over the work load and how slow people are moving that cause me to wake up. I am trained, unintentionally. I've connected myself with the emotions of those around me and have hardwired the noises of modern day conviences into my system and when my body is trying to relax and flush these sources of concern sometimes it unnerves me.
You are the product of your society. Like it or not, the majority of the things you think, feel, and do are the product of how and by whom you were and raised. Big Brother is always watching.
