"All scientists should be skeptics. The reason why is that, even with the best of scientific measurements, we can come up with all kinds of explanations of what those measurements mean in terms of cause and effect, and yet most of those explanations are wrong. It's really easy to be wrong in science ... it's really hard to be right."

The Domino Effect could stand for anything. It could be just the simple game of the domino rocks falling off one after another, all kinds of decision we make that come back to our face. For example take an anorexic model that stops eating until she dies, or the bombs that a are thrown in a war and the effect they have on people, or even something simple as listening to a record that you like until you get bored of it and leave it in your shelf.
