Obedience
Obedience, in human behavior, is a form of "social influence in which a person yields to explicit instructions or orders from an authority figure". Obedience is generally distinguished from compliance, which some authors define as behavior influenced by peers while others use it as a more general term for positive responses to another individual's request, and from conformity, which is behavior intended to match that of the majority. Depending on context, obedience can be seen as moral, immoral, or amoral. For example, in psychological research, individuals are usually confronted with immoral demands designed to elicit an internal conflict. If individuals still choose to submit to the demand, they are acting obediently.
Humans have been shown to be obedient in the presence of perceived legitimate authority figures, as shown by the Milgram experiment in the 1960s, which was carried out by Stanley Milgram to find out how the Nazis managed to get ordinary people to take part in the mass murders of the Holocaust. The experiment showed that obedience to authority was the norm, not the exception. Regarding obedience, Milgram said that "Obedience is as basic an element in the structure of social life as one can point to. Some system of authority is a requirement of all communal living, and it is only the man dwelling in isolation who is not forced to respond, through defiance or submission, to the commands of others." A similar conclusion was reached in the Stanford prison experiment.
Experimental studies
Classical methods and results
Although other fields have studied obedience, social psychology has been primarily responsible for the advancement of research on obedience. It has been studied experimentally in several different ways.Milgram's experiment
In one classical study, Stanley Milgram created a highly controversial yet often replicated study. Like many other experiments in psychology, Milgram's setup involved deception of the participants. In the experiment, subjects were told they were going to take part in a study of the effects of punishment on learning. In reality, the experiment focuses on people's willingness to obey malevolent authority. Each subject served as a teacher of associations between arbitrary pairs of words. After meeting the "teacher" at the beginning of the experiment, the "learner" sat in another room and could be heard, but not seen. Teachers were told to give the "learner" electric shocks of increasing severity for each wrong answer. If subjects questioned the procedure, the "researcher" would encourage them to continue. Subjects were told to ignore the agonized screams of the learner, his desire to be untied and stop the experiment, and his pleas that his life was at risk and that he suffered from a heart condition. The experiment, the "researcher" insisted, had to go on. The dependent variable in this experiment was the voltage amount of shocks administered.Zimbardo's experiment
The other classical study on obedience was conducted at Stanford University during the 1970s. Phillip Zimbardo was the main psychologist responsible for the experiment. In the Stanford Prison Experiment, college age students were put into a pseudo prison environment in order to study the impacts of "social forces" on participants behavior. Unlike the Milgram study in which each participant underwent the same experimental conditions, here using random assignment half the participants were prison guards and the other half were prisoners. The experimental setting was made to physically resemble a prison while simultaneously inducing "a psychological state of imprisonment".Results
The Milgram study found that most participants would obey orders even when obedience posed severe harm to others. With encouragement from a perceived authority figure, about two-thirds of the participants were willing to administer the highest level of shock to the learner. This result was surprising to Milgram because he thought that "subjects have learned from childhood that it is a fundamental breach of moral conduct to hurt another person against his will". Milgram attempted to explain how ordinary people were capable of performing potentially lethal acts against other human beings by suggesting that participants may have entered into an agentic state, where they allowed the authority figure to take responsibility for their own actions. Another unanticipated discovery was the tension that the procedure caused. Subjects expressed signs of tension and emotional strain especially after administering the powerful shocks. 3 of the subjects had full-blown uncontrollable seizures, and on one occasion the experiment was stopped.Zimbardo obtained similar results as the guards in the study obeyed orders and turned aggressive. Prisoners likewise were hostile to and resented their guards. The cruelty of the "guards" and the consequent stress of the "prisoners," forced Zimbardo to terminate the experiment prematurely, after 6 days.
Modern methods and results
The previous two studies greatly influenced how modern psychologists think about obedience. Milgram's study in particular generated a large response from the psychology community. In a modern study, Jerry Burger replicated Milgram's method with a few alterations. Burger's method was identical to Milgram's except when the shocks reached 150 volts, participants decided whether or not they wanted to continue and then the experiment ended. To ensure the safety of the participants, Burger added a two-step screening process; this was to rule out any participants that may react negatively to the experiment. In the modeled refusal condition, two confederates were used, where one confederate acted as the learner and the other was the teacher. The teacher stopped after going up to 90 volts, and the participant was asked to continue where the confederate left off. This methodology was considered more ethical because many of the adverse psychological effects seen in previous studies' participants occurred after moving past 150 volts. Additionally, since Milgram's study only used men, Burger tried to determine if there were differences between genders in his study and randomly assigned equal numbers of men and women to the experimental conditions.Using data from his previous study, Burger probed participant's thoughts about obedience. Participants' comments from the previous study were coded for the number of times they mentioned "personal responsibility and the learner's well being". The number of prods the participants used in the first experiment were also measured.
Another study that used a partial replication of Milgram's work changed the experimental setting. In one of the Utrecht University studies on obedience, participants were instructed to make a confederate who was taking an employment test feel uncomfortable. Participants were told to make all of the instructed stress remarks to the confederate that ultimately made him fail in the experimental condition, but in the control condition they were not told to make stressful remarks. The dependent measurements were whether or not the participant made all of the stress remarks and the number of stress remarks.
Following the Utrecht studies, another study used the stress remarks method to see how long participants would obey authority. The dependent measures for this experiment were the number of stress remarks made and a separate measure of personality designed to measure individual differences.
Neuroscience has only recently begun to approach the question of obedience, bringing novel but complementary perspectives on how obeying or issuing commands impacts brain functioning, fostering conditions for moral transgressions. The experimental protocol, inspired by Milgram, does not rely on deception and involves real behaviors. A participant assigned the role of agent must either freely decide or receive orders from the experimenter to deliver or withhold a mildly painful electric shock to another participant in exchange for €0.05. In a study conducted in 2020, fMRI results indicated that seeing the shock delivered to the victim triggered activations in the anterior cingulate cortex and the anterior insula, key brain regions associated with empathy. However, such activations were lower in the coerced condition compared to the free-choice condition, consistent with participants' subjective perception of the victim's pain. Activity in brain regions associated with the interpersonal feeling of guilt was also reduced when participants obeyed orders compared to acting freely. Other studies showed that the sense of agency, as measured through the implicit task of time perception, was reduced in the coerced compared to the free-choice condition, suggesting that the sense of agency diminishes when individuals obey orders compared to acting freely. These neuroscience studies highlight how obeying orders alters our natural aversion to hurting others.
Results
Burger's first study had results similar to the ones found in Milgram's previous study. The rates of obedience were very similar to those found in the Milgram study, showing that participants' tendency to obey has not declined over time. Additionally, Burger found that both genders exhibited similar behavior, suggesting that obedience will occur in participants independent of gender.In Burger's follow-up study, he found that participants that worried about the well-being of the learner were more hesitant to continue the study. He also found that the more the experimenter prodded the participant to continue, the more likely they were to stop the experiment.
The Utrecht University study also replicated Milgram's results. They found that although participants indicated they did not enjoy the task, over 90% of them completed the experiment.
The Bocchiaro and Zimbardo study had similar levels of obedience compared to the Milgram and Utrecht studies. They also found that participants would either stop the experiment at the first sign of the learner's pleas or would continue until the end of the experiment.
In addition to the above studies, additional research using participants from different cultures also found participants to be obedient.
