Modern Replications Reveal Why Ordinary People Obey Immoral Orders

Key points

• In 1961, Stanley Milgram’s Yale experiment found 65% of men delivered maximum fake shocks to a victim when ordered by an authority figure.
• Jerry Burger’s 2009 replication showed 70% of mixed-gender participants obeyed to the end, with no significant difference between men and women.
• Tomasz Grzyb’s 2015 study found 90% of participants obeyed, highlighting that personality traits are poor predictors of obedience.
• Emilie Caspar’s fMRI research shows that obeying orders reduces activity in brain regions associated with empathy, guilt, and agency, making compliance less effortful than resistance.
• Key drivers of obedience include the authority figure accepting responsibility, the lack of time for reflection, and the 'foot in the door' effect of gradual escalation.
• Resisting immoral orders is easier when individuals take time to reflect, recognize shifted responsibility, or have witnessed moral role models in their upbringing.

Background

The Milgram experiment, conducted in 1961, remains a landmark study in social psychology, often cited to explain how ordinary people participated in atrocities like the Holocaust. While Milgram’s findings were influential, critics noted that blind obedience does not fully explain complex real-world genocides, which involve stages of discrimination and dehumanization before the final phase of extermination. Modern replications aim to understand the specific situational and neurological factors that lead to compliance, rather than relying solely on historical analogy.

Why it matters

Understanding the mechanics of obedience helps explain how ordinary people can participate in harmful actions, from online aggression to historical atrocities. By identifying that obedience is often a default, low-energy response, and that resistance requires active cognitive effort, these findings highlight the importance of building systems that prevent unchecked power and encourage individual reflection. Recognizing that moral courage can be cultivated through role models and awareness of social pressure offers practical ways to foster ethical behavior in everyday life and institutional settings.

What to watch

Researchers continue to explore how early exposure to moral role models and the design of social systems can reduce the likelihood of obedience to harmful orders. Future studies may focus on how digital anonymity and modern authority structures influence compliance, and how individuals can be trained to recognize and resist the psychological triggers that lead to immoral obedience.
