Essentialism: The Disciplined Pursuit of Less

by Greg McKeown

In the summer of 1971, Zimbardo took healthy Stanford students, assigned them roles as either “guards” or “inmates,” and locked them in a makeshift “prison” in the basement of Stanford University. In just days, the “prisoners” began to demonstrate symptoms of depression and extreme stress, while the “guards” began to act cruel and sadistic (the experiment was ended early, for obvious reasons). The point is that simply being treated like prisoners and guards had, over the course of just a few days, created a momentum that caused the subjects to act like prisoners and guards. The Stanford prison experiment is legendary, and much has been written about its many implications. But what I wondered was this: If simply being treated in a certain way conditioned these Stanford students gradually to adopt these negative behaviours, could the same kind of conditioning work for more positive behaviour too?
