Shame and shaming have been powerful tools since the expulsion of Adam and Eve from Paradise, but with the rise of social media the brutality of shaming has reached a cultural boiling point. While mistaken as a medium for social justice, where the powerless are given a voice, cyber-mobbing often takes on the characteristics of medieval punishment. In this lecture, Andrea Köhler, the New York correspondent of the Neue Zürcher Zeitung, discusses how shamers can wreak havoc on the lives of those who have offended their values. Shamers often think of themselves as being morally superior and claim to be unaware of the devastating effects of their actions on their victims. But as more and more people end up on the receiving end of cybermobs, the destructiveness of public shaming has become an international problem that must be reckoned with.
