Following is an interesting article I thought would be of interest to any one. We might not realise the number of times we ask this question to ourselves, over and over.
The debate about ordinary people committing evil deeds rolls on. But in a personal viewpoint Prof Phil Zimbardo, creator of the Stanford Prison Experiment, says its time to get to grips with why wrongdoing happens.
In 1971 I became superintendent of the Stanford Prison, a mock prison run by psychologists. I was a young psychology professor at Stanford University, and I wanted to understand what happens when you put good people in a bad place.
To do so, it was necessary to conduct a controlled experiment, so my graduate assistants and I selected college-student volunteers - normal, healthy young men with no history of crime or violence - and randomly assigned them the roles of prisoner or guard.
During the extended experiment, we would observe and record everything that happened. The inmates would live in their cells and the prison yard 24/7 - the guards would work eight-hour shifts.
Ordinary people can succumb to social pressure to commit acts that would otherwise be unthinkable
Our simulation tried to create a psychology of imprisonment in the minds of all participants, with all-powerful guards dominating powerless prisoners. To increase the real-life feel, we arranged for actual mass arrests and booking by the Palo Alto police; visits by a prison chaplain, a public defender, and parents; even parole board hearings.
Though not part of the plan, there were also prisoner rebellions. And, notoriously, there was chilling abuse and torture by the guards.
The experiment was supposed to last two weeks, but we had to pull the plug after only six days because nearly half the prisoners had emotional breakdowns in response to the extreme stress and psychological torments invented by their guards - good, young men who'd been overwhelmed by situational forces in the roles they were playing.
Fast-forward to April 2004. Horrific images flash across our television screens - nightmarish abuses of Iraqi prisoners by young American soldiers, the male and female military police reservists stationed at Abu Ghraib. Military commanders condemn the criminal actions of a "few bad apples," asserting that such abuses are not systemic in our military prisons.
The images were shocking to me, but not unfamiliar. They were, in fact, strikingly similar to what I had seen at Stanford - prisoners naked, bags over their heads, forced into sexually humiliating poses. Could the perpetrators of these evils be like the young men in my prison - "good apples" who happened to find themselves in a "bad barrel"?
Was their behaviour shaped by the same sort of social psychological forces that had operated in the Stanford Prison Experiment? My conclusion, after becoming an expert witness for one of the military policemen and reviewing all the evidence of the investigations into these abuses, was that the parallels were palpable. Indeed, one investigative report highlighted the fact that the "landmark Stanford study" should have been a cautionary tale in preventing the Abu Ghraib abuses.
Historical inquiry and behavioural science have demonstrated the "banality of evil" - the fact that, given certain conditions, ordinary people can succumb to social pressure to commit acts that would otherwise be unthinkable.
To be sure, few of us will ever end up as inmates or guards in military or civilian or mock prisons, but many of us find ourselves in relationships where we dominate other people or are dominated by them.
We spend our lives in institutions of one kind or another, from families, schools, and businesses, to homes for the elderly. And many times we bow to the will of the group even when it conflicts with our values.
Prejudiced beliefs
In the prisons at Stanford and Abu Ghraib, men and women did terrible things to other people in part because responsibility for their actions was diffused, rather than focused on each of them as individuals; we find ourselves in a similar situation whenever we witness someone else's trouble but fail to help because we assume others will.
Likewise, the prisoners at Stanford and Abu Ghraib suffered unnecessarily because the guards regarded them as less than human; dehumanisation allowed the guards to treat prisoners as lower beings. The same applies to us when we allow members of a minority group to be derogated as inferior.
Prejudiced beliefs lead to discrimination, and in turn to abuse. Situational forces affect us when we're acting in the capacity of a role we've assumed; when rules govern our behaviour; when we're in uniforms or dressed in ways that conceal our identity; and of course when we're in a group whose acceptance seems vital to our self-image.
We want to believe that we are "good," moral, and self-aware. We want to believe that we're different from "bad" or "evil" people. Thinking so is essential to maintaining a sense of personal dignity and self worth. But the line between good and evil is permeable, like the cell walls of our body that allow movement of chemicals across their boundaries.
Anything that any human being has ever done - anything imaginable - is potentially doable by any of us in the same situation.
This is not to excuse immoral behaviour; the point is simply that understanding how someone could have engaged in wrongdoing, rather than dismissing it as a bad deed done by a bad person, allows us to identify corrosive social forces - the very same forces we need to counteract if we want to avoid going down the same wrong path.
