What the various totalitarian experiments tell us quite clearly is that most people most of the time are formed by the circumstances in which they find themselves. That does not mean that individual personality variables do not exist, or that there will not always be exceptions. There will always be extraordinary people like Władysław Bartoszewski, who seems to have emerged from childhood with an uncanny moral lucidity. But as a general rule: if you put people in bad circumstances, you will not, on a large scale, get good outcomes.
