Hand someone a uniform and power over others, and we assume cruelty follows. But when researchers ran a careful prison study and simply left the guards alone, the guards did not turn into tyrants. Instead the prisoners showed solidarity (they stuck together and had each other’s backs), and as one cohesive (tight-knit, united) group they ended up with the upper hand (Reicher & Haslam, 2006).
A role does not make the monster. Someone has to hand you the role, tell you the cruelty is okay, and you have to step into it.
The role does not flip a switch
Put a normal person in a guard’s uniform and, on their own, nothing dramatic happens. The costume is not a curse. Cruelty shows up only when two things come together:
- Someone in charge makes it feel okay. A boss, a rulebook, an authority signalling that being harsh is expected and rewarded. Without that green light, most people hold back.
- You start seeing yourself as “one of them.” “I’m a guard now.” Once you step into the role in your own head, its behavior becomes your behavior.
When both click into place, ordinary people do cruel things and feel justified. When either is missing, they don’t.
You are never just a puppet the situation controls. You are someone who chooses to step in, and that choice can be refused.
What the famous study actually showed
The 1971 Stanford Prison Experiment is what made this topic famous: students randomly cast as guards and prisoners, the guards turning harsh, the study stopped early. It is usually told as proof that a role alone corrupts anyone.
But the records tell a different story. The guards were coached to be tough, given rules built to dehumanize prisoners, and reprimanded when they went soft, and the lead researcher ran the prison from the inside (Le Texier, 2019).
So it never showed a uniform spontaneously turning people cruel. It showed the real mechanism: people get harsh when an authority directs and rewards it. Same lesson as the Milgram experiments, one room over.
Solidarity is the antidote
Here is the hopeful half. The thing that stops the slide is people sticking together.
In the controlled study, the prisoners who stuck together and refused to accept the roles handed to them weren’t crushed. As a group, they were stronger than the guards. Cruelty needs its targets alone and its enforcers all thinking of themselves as one team. Break either of those, and it loses its grip.
Why this matters
- “The role made me do it” is only half true. A situation can push you hard, but you still step in and act, and that is where responsibility lives.
- Watch for the two ingredients, not the costume. The danger is a legitimizing boss plus a group you start calling “us,” not the uniform itself.
- Stay connected, and stay yourself. People who keep their own conscience and link arms with others are the ones who resist.
Bad systems do not flip a switch inside good people. They recruit them, one permission and one “us” at a time. Which means they can be refused.
