The Shock Heard Around The World: Milgram’s Experiment

If you were ordered to deliver a 400-voltage-shock to another human being by an authority figure, would you do it? Most people would answer “No,” sure of the fact that they would never inflict pain on another person. However, the Milgram Experiment proved otherwise. Why is it that so many individuals obey orders when they are told to, even when they know the orders are wrong? Social psychologist Stanley Milgram researched the power of authority and obedience. Milgram’s experiment on obedience analyzes the psychological processes underlying compliance with orders to commit despicable acts.1 

Experiments began in July 1961, three months after the trial of World War II criminal, Adolf Eichmann. He was responsible for ordering the deaths of millions of Jews, but he said he was “just following orders.” He claimed that he did it simply because he was told to. This made Milgram question the power of authority. He questioned, “Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Could we call them all accomplices?” Throughout history soldiers have followed orders to murder innocent people. So many examples include the Nazi’s killing the Jews, the Turkish slaughter of the Armenians, and the Serbian killings of both Bosnian and Kosovar Muslims. We understand that these were terrible acts and wonder how anyone is capable of committing them. But how many of us would refuse to follow these orders if they came from an authority figure, someone in control, and who obtained power over you?2

The purpose of the experiment was to test whether ordinary people were capable of inflicting harm on others if an authority figure pressured them to do so. Using a newspaper ad, forty men were recruited for the experiment, and each person was paid $4.50. Participants were led to believe that they were assisting in an unrelated experiment, in which they had to administer electric shocks to a “learner.”  And they were told that the fake electric shocks were to be gradually increased to fatal levels, if they had been real. Three individuals took part in each session: the “experimenter” (in charge to the session), the “teacher” (the volunteer who was misled to believe that they were merely assisting), and the “learner” (an actor and a confederate of the experimenter who pretended to be a volunteer).3

The actor and participant arrived to the session together, and they both drew slips of paper to determine their roles. Each slip of paper said “Teacher,” but the actor claims to have “Learner,” to guarantee that the subject will always be the “Teacher.” Milgram created a shock generator with different shock levels, starting at 30 volts and going all the way up to 450 volts. Each volt level had a label, such as “slight shock,” “moderate shock,” and “Danger: Extreme Shock.” Whenever an incorrect answer was given from the “Learner,” he was given a shock.4 The participant believed that he was delivering real shocks, but the “student” was a confederate in the experiment, and was just pretending to be shocked. As the experiment progressed, the experimenter would hear the student plead to be released or complain of a heart problem. Once it reached 300-volts, the student would demand to stop. The student would refuse to answer anymore questions, the experimenter instructed the participant to treat the silence like an incorrect answer and shock them.5

Most participants would start to feel they needed to stop before the voltages became too high. They would ask if they should continue and the experimenters would tell them specific verbal encouragements. These were given in this order: “Please continue,” and “The experiment requires that you continue,” and “It is absolutely essential that you continue,” or “You have no other choice, you must go on.” If the subject still wanted to stop after all of these verbal encouragements, the experimenter ended the experiment. If they did not choose to stop, it ended after the subject had given the maximum shock three times during the session. Out of the forty participants, twenty-six delivered the maximum shock while fourteen stopped before reaching the higher levels.6

The experimenter used specific prods for any questions the subject may have had. If the subject was worried about the learner wanting to stop, the experimenter replied, “Whether the learner likes it or not, you must go on until he has learned all the word pairs correctly, so please go on.” While most of the participants were agitated at the experimenter, they still followed the orders that were given.7 The participants experienced anxiety from the experiment, and they learned the truth at the end. The researchers explained they used deception. Milgram raised moral questions, such as why did so many of the participants in this experiment perform a seemingly sadistic act when instructed by an authority figure? Milgram came to the conclusion that, “Ordinary people, simply doing their jobs, and without any particular hostility on their part, can become agents in a terrible destructive process. Moreover, even when the destructive effects of their work become patently clear, and they are asked to carry out actions incompatible with fundamental standards of morality, relatively few people have the resources needed to resist authority.” Milgram’s experiment has inspired psychologists around the world to research more about what makes people comply with orders and what makes them question authority.8

  1. I learned about the Milgram experiment in General Psychology, but I did not realize that the experiment was generated to see test the Nazis and their claims that they were just following orders. I also know there are debates as to whether the experiment should have been allowed at all. While I worry about the mental trauma the volunteers could have experienced, I also cannot negate the benefits and outcome the experiment portrayed.

  2. This was a very well written and interesting article. I knew a little bit about the Milgram Experiment, but I had mostly heard about the debates regarding whether this experiment should have been allowed to occur, or if the psychological damage the volunteers could take was too high to deem appropriate and moral. This is an incredibly relevant and interesting topic.
