Zimbardo dared to ask the question: where does one's identity end and one's role begin? (1973). The two seem to be invariably intertwined, each having an effect on the other. The heavy weighing expectations of our roles seem to form parts of our identity. Are we, as people, greater than the sum of our roles? Or are we truly defined by our roles, and our roles alone? Does being a parent, or a spouse, or an employee of a certain company truly define you as a person? After reading Zimbardo's The Lucifer Effect and watching many of his public speeches, I believe he would say that we have the power to use our roles for good. Also, that we are capable of transcending and breaking free from the negative, evil roles in our lives. Philip G. Zimbardo conducted one of the most important experiments in Social Psychology. The Stanford Prison Experiment gave us amazing insight into how extreme we will go in our actions and behaviors to fulfill our roles.
