what does it mean, to be a human being?

A Simulation Study of thePsychology of Imprisonment

Conducted at Stanford University

"Welcome to the Stanford Prison Experiment web site, which features an extensive slide show and information about this classic psychology experiment, including parallels with the abuse of prisoners at Abu Ghraib. What happens when you put good people in an evil place? Does humanity win over evil, or does evil triumph? These are some of the questions we posed in this dramatic simulation of prison life conducted in the summer of 1971 at Stanford University."
