Normal people can take ghastly actions. - Hannah Arendt

"I had been conducting research for some years on deindividuation, vandalism and dehumanization that illustrated the ease with which ordinary people could be led to engage in anti-social acts by putting them in situations where they felt anonymous, or they could perceive of others in ways that made them less than human, as enemies or objects," - Zimbardo (psychologist behind the Stanford Prison Experiment) to the Toronto symposium in the summer of 1996.
