The Experimental Setup and Methodology
The Milgram experiment procedure involved elaborate staging to create a believable scenario. Two participants arrived at the lab - one was actually a confederate (actor) playing the "learner" role, while the other was the genuine subject assigned as the "teacher." Through a rigged drawing, the real participant always became the teacher.
The setup included a fake shock generator with switches labeled from 15 to 450 volts, with ominous warnings like "Danger: Severe Shock" at the higher levels. To enhance credibility, teachers received a mild 45-volt shock themselves, convincing them the equipment was real.
The learning task involved word pairs, with the teacher instructed to shock the learner for wrong answers, increasing the voltage each time. While no actual shocks were delivered, the learner (acting from a script) would increasingly protest, complain of heart problems, and eventually fall silent at the highest levels.
Example: A typical word pair might be "Blue - Sky" or "Wild - Duck." If the learner gave an incorrect response, the teacher had to administer an electric shock, starting at 15 volts and increasing by 15 volts for each wrong answer.
