I once met a man who was indulging himself in a massive, nationwide Pavlovian experiment. He was the Marketing director of a very large Pizza chain that focused on delivering
He sponsored a major Saturday night show, so the bumper breaks were showing gorgeous shots of cheesy Pizza. He then showed me a graph of orders from his national system, cross referenced with a graph showing the bumper break times. There was basically a 60 second delay between the bumper break and people ordering Pizza. Even with some reduction from "I was going to order take away in the break anyway" the correlation was scary, really very very scary. A nation of Pavlovian Homers shouting to their families "SHALL I GET THE PIZZA IN LUV?" and killing them slowly with Coca-Cola, Salt and Cheesy fat.
At that point, most people would have been repulsed and become worried for the state of the nation. I wondered how I could make money out of these lazy, fat bastards. I really did. I could blame the fact I came from a poor family, so have had a pathological fear of being poor again. The reality is I am just an evil bastard.
