The Stanford Prison Experiment: Examining the Power of Social Roles

🧠 Quick Study Guide: The Stanford Prison Experiment

• 🗓️ Date: Conducted in 1971 by Philip Zimbardo and his team at Stanford University.
• 🎯 Aim: To investigate how readily people would conform to the roles of guard and prisoner in a simulated prison environment.
• 🔬 Methodology: 24 male college students, deemed psychologically stable, were randomly assigned roles of 'prisoner' or 'guard'. The 'prison' was set up in the basement of Stanford's psychology department.
• ⏱️ Duration: Intended for two weeks but terminated after only six days due to the participants' alarming behavior.
• 📈 Key Findings:
  • 👮 Guards: Became increasingly aggressive, authoritarian, and abusive towards prisoners, often exceeding their assigned duties.
  • 🔗 Prisoners: Showed signs of extreme stress, emotional breakdown, depression, and learned helplessness, becoming submissive and dehumanized.
• 💡 Core Concept: Demonstrated the powerful influence of social roles, situational factors, and deindividuation on human behavior, rather than individual personality traits.
• ⚖️ Ethical Concerns: Significant ethical violations, including lack of fully informed consent, psychological harm to participants, and Zimbardo's dual role as researcher and prison superintendent.
