Philip Zimbardo

This famous psychologist's notorious 1971 Stanford Prison Experiment had to be canceled after Day 5, because the division of college students into "guards" and "prisoners" became grimly realistic, cruel, and ultimately sadistic. This experiment, decades later, is still studied by psychologists interested in human behavior.

Ideas for my first experiments in human aggression came from discussions we had in a research seminar about William Golding's Lord of the Flies.
