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 (as part of the
Milgram experiment) 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" (an accomplice of the experimenter) 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" (again, an accomplice of Milgram) 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. 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". 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. 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 (measuring absolute obedience) and the number of stress remarks (relative obedience). 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 (the "victim") 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 (ACC) and the anterior insula (AI), 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. Australia, and Jordan) also found participants to be obedient.
Implications One of the major assumptions of obedience research is that the effect is caused only by the experimental conditions, and
Thomas Blass' research contests this point, as in some cases participant factors involving personality could potentially influence the results. In one of Blass' reviews on obedience, he found that participant's personalities can impact how they respond to authority, He replicated this finding in his own research, as in one of his experiments, he found that when watching portions of the original Milgram studies on film, participants placed less responsibility on those punishing the learner when they scored high on measures of authoritarianism. In addition to personality factors, participants who are resistant to obeying authority had high levels of
social intelligence. ==Other research==
