| 🏥 Hofling Hospital Study | 1966 | Investigating obedience to medical authority in a real hospital setting. | 21 out of 22 nurses were willing to administer a dangerous, unauthorized drug dose from an unknown doctor over the phone, despite clear hospital rules. | Demonstrated obedience in a professional, real-world context, highlighting institutional authority and professional norms over ethical guidelines. Less direct harm inflicted by participants, but potential for it. |
| 🔒 Stanford Prison Experiment (Zimbardo) | 1971 | Examining the psychological effects of perceived power, authority, and situational roles. | Participants quickly adopted their assigned roles (guards became authoritarian, prisoners became submissive), leading to abusive behavior and psychological distress, forcing early termination. | Focused on how roles and situations dictate behavior, rather than direct commands from a single authority figure. Showed the power of institutional context in shaping obedience and cruelty. |
| 📺 The Game of Death (La Zone Xtrême) | 2010 | A French TV show replicating Milgram's experiment with a fake game show setting. | 80% of contestants delivered maximum "shocks" (460 volts) to a supposed stranger, coerced by the game show host and audience encouragement. | Updated Milgram's findings in a modern, media-driven context, showing that the phenomenon of obedience persists even with increased public awareness of Milgram's original study. |
| ✈️ Pilot/Co-pilot Study (Rank & Jacobson) | 1977 | Replication of Hofling's study with a more realistic, higher-stakes scenario involving nurses and a known drug. | Only 2 out of 18 nurses obeyed the doctor's order to administer an excessive dose of Valium to a patient when the drug was familiar and the doctor was known, suggesting familiarity and peer consultation reduce obedience. | Challenged Hofling's findings by introducing variables (known drug, opportunity for peer consultation) that significantly reduced obedience, emphasizing the role of situational factors and knowledge. |
| 📚 Burger's Replication of Milgram | 2009 | A partial replication of Milgram's experiment with modern ethical safeguards to assess obedience levels today. | Found obedience rates only slightly lower than Milgram's (70% willing to go past 150V), suggesting that the tendency to obey authority has not significantly decreased over time. | Directly replicated and updated Milgram, confirming the enduring power of authority while adhering to contemporary ethical standards (e.g., stopping at 150V, prescreening participants). |
