In the early 1600s, pioneering astronomer Johannes Kepler put forth his three laws of planetary motion, which, for the first time, provided an accurate and evidence-based description of the movement of the Solar System's planets around the Sun. By the end of the century, Isaac Newton followed Kepler's example with three laws of his own, describing the relationship between an object and the forces acting on it, thus laying the foundations for classical mechanics. Almost exactly three hundred years later, Carlo M. Cipolla, a professor of economic history at the University of California - Berkeley, introduced a set of laws no less revelatory than those of Kepler or Newton: The Basic Laws of Human Stupidity.

While these laws are not taught in grade school, they do hold lessons worthy of reflection in this modern era. Stupidity today is on display more than ever before -- on TV, YouTube, and the city streets you frequent each and every day. To better react to and avoid such dimwitted behavior, one must first understand it. Cipolla's insightful set of five laws is a helpful guide.

It's true, an individual's actions have a potential for a multiplied effect, think "Butterfly Effect".
But, add to that mob mentality, and there's no limit to stupid, as evidenced by the actions of OWS.
