What Was Zimbardo’s Stanford Prison Experiment?

Today, let’s dive into a bit of moral reflection, focusing on racial prejudice.

First off, just a quick reminder of the Zimbardo’s prison experiment. After reviewing the material, I’m even more inclined to recommend this video. Beyond what’s immediately visible, there’s another layer worth exploring.

Notice how deeply some participants’ lives were changed by this experiment. Not everyone was featured, but one of the “prisoners” later became a prison psychologist, profoundly affected by his experience.

Even Zimbardo himself ended up marrying a student. This student spoke out after six days, calling the experiment unethical and demanding it be stopped.

According to Le Texier (2019), a later archival investigation found that guards in the Stanford Prison Experiment were explicitly coached to be cruel. Overall, this complicates its traditional interpretation as spontaneous evidence of situational evil.

It seems to me that everyone in that simulated prison tapped into something huge. This represents an awakened force that often goes unnoticed in our everyday lives.

Zimbardo, in his later reports, was careful, avoiding broad generalizations and risky conclusions. Yet, the underlying messages were clear.

Are We Born Evil?

To me, the big lesson is that we’re all born with the potential for violence, betrayal, theft, and worse.

It’s the structure of society and the law that keeps us in check. Imagine if we unleashed our true selves; civilization might collapse.

While it’s not common, when people are given unchecked power, their true nature quickly shows. According to Kipnis (1972), holding unchecked power over others measurably changes how people treat and perceive them. As a result, this often makes the powerful more self-interested and dismissive.

However, according to Reicher and Haslam (2006), the BBC Prison Study found that tyranny is not automatic. Instead, it emerges only when people actively identify with a group role, rather than being an inevitable product of assigned power.

What surprises me is the lack of public discussion on this topic. It’s as if recognizing human aggression and cruelty would somehow disrupt our collective harmony.

Maybe it’s because admitting the darkness within us conflicts with the idea of our capacity for higher emotions. This implies that friendship, love, attachment, and responsibility might be illusions—products of popular propaganda.

In my view, that’s not entirely true. I believe humanity has both a brutal and a romantic side, and these aspects are not contradictory. This perspective has been with me since childhood and hasn’t left me disillusioned with humanity.

What Are the Roots of Racism?

On another note, I’d recommend checking out another thought-provoking piece. This is a more recent experiment exploring the roots of prejudice against minorities, especially racial ones.

It sheds light on the tough situation faced by minority children, particularly in the United States, including those in schools. This experiment might not be as dramatic as Zimbardo’s, but it’s definitely worth watching.

According to Stewart, Laduke, Bracht, Sweet and Gamarel (2003), they conducted a program evaluation of Jane Elliott’s “Blue-Eyes/Brown-Eyes” exercise. The evaluation found it reduced prejudice toward some groups more than others, with effects varying by the target group.
