Sample question
In psychology, few studies are as ethically controversial and scientifically impactful as the Stanford Prison Experiment. Critically assess the psychological mechanisms at play in the study, and argue whether its findings should still be considered relevant in modern psychology.
Sample response
De-individuation and the Fragility of Morality
​
The Stanford Prison Experiment (SPE), led by Philip Zimbardo in 1971, is one of the most cited, and debated studies in psychology. At its core, the SPE demonstrates how situational forces, rather than inherent personality traits, can lead ordinary people to engage in abusive behavior. In only six days, student volunteers acting as prison guards began exhibiting authoritarian cruelty toward their peers, while "prisoners" developed signs of psychological distress. This essay argues that, despite its methodological flaws, the SPE remains a stark and useful case study in deindividuation, power dynamics, and the psychology of institutions.
​
Mechanisms of Moral Erosion
​
Central to the SPE’s outcome is deindividuation, a psychological state where self-awareness diminishes and individuals lose their sense of personal responsibility. Guards in the experiment wore uniforms and sunglasses, which made them somewhat anonymous and allowed behavior that would otherwise be inhibited by conscience. Zimbardo himself described how quickly participants internalized their roles, with one guard stating: “I was surprised at myself… I was actually beginning to enjoy the power I had.” This echoes Milgram’s work on obedience, in which perceived authority nullifies moral resistance.
​
Additionally, social identity theory explains how group membership (guards vs. prisoners) contributed to in-group favoritism and out-group hostility. The rigid structure of roles created a feedback loop: the more guards asserted dominance, the more prisoners resisted or broke down, reinforcing authoritarian behavior.
​
Ethical Critique, Scientific Limits, and Modern Relevance
​
The SPE is now widely criticized for lacking clear controls and for Zimbardo’s dual role as superintendent and researcher, which introduced confirmation bias. Nevertheless, its value lies in its visceral demonstration of how institutional settings can distort moral reasoning.
​
Though modern ethics would prevent such a study today, the SPE continues to be relevant, particularly in understanding environments like prisons, the military, and law enforcement. It also speaks to broader issues of power and accountability, themes that remain at the heart of contemporary psychology and public discourse.
​
As psychologist Steven Pinker writes, “Situations matter. Social roles matter. And the greatest crimes in history were committed not by monsters, but by men in uniforms.” In this way, the SPE’s haunting lesson lingers: given the wrong context, any of us might lose ourselves.
