The baseline study (I will define baseline study as his first initial experiment) done for his experiment, which was then followed by seventeen variations to the experiment, showed that 65 percent of participants would adhere to authority. Milgram had 40 men come to Yale and they were “assigned” either a “learner” or “teacher” role, not knowing that the learner role was truly a confederate. In the baseline study, the teacher was in a room with a man in a lab coat and would perform a memory test with the learner. For each wrong answer the learner was to give, the teacher would administer a shock. “The generator had 30 different switches running in 15-volt increments from 15 to 450-volts. The higher levels of shock were labeled in big letters as ‘Intense Shock’, ‘Extremely Intensity Shock’, ‘Danger: Severe Shock’, and, ominously ‘XXX’” (Jones, 2006, p. 397). Once the shock hit 300-volts, the learner would pound, vigorously, on the laboratory walls, this was repeated at 315-volts, but not heard from again after that level.
Milgram’s 17 variation experiments duplicated the baseline experiment with slight variations. Experiment 2 was a voice-feedback, where the teacher could hear the learner’s complaints from an adjacent room. Experiment 3 focused on proximity, placing the learner in the same room as the teacher, only a few feet away from one another. Experiment 4 was a touch-proximity, where the teacher and learner were in the same room and the teacher had to physically make the learner touch the shock plate.
The 3 variations of the experiment altered how many participants carried out the acts of obedience. “35 percent of the subjects defied the experimenter in the Remote condition, 37.5 percent in Voice-feedback, 60 percent in Proximity, and 70 percent in Touch-Proximity” (Milgram, 1974, p. 53). Other variations of the experiments changed whether or not the man in the lab coat (who was a high school biology teacher) was present in the room and the location of the physical experiment (moved it off of Yale’s campus).
