"How do you go from a backyard scientist with no formal training to the world authority on antibiotic resistant disease within a week? How can spam emails subtly shift the course of world politics? How can you tell the difference between a well established fact, and a factoid repeated across multiple formats in a deliberate attempt to create false consensus? In this talk Matthew Borgatti will take you through the strange world of manipulating public opinion and individual behavior through campaigns of misinformation. We'll touch on how rumors are fabricated, how tantalizing facts remain in the public consciousness even long after they've been proven false, and the disturbingly effective manipulations that are possible with the mountains of data that can be gleaned from social networking sites."
