Milgram's study procedure
1. Recruited 40 participants for each variation of the study
2. Told participants the study measured how punishment affected learning (deception)
3. Had two experimental confederates: an experimenter, and a 47-year-old man introduced as another volunteer participant
4. Rigged the drawing of lots so the real participant would always be the "teacher" and the confederate the "learner"
5. The "teacher" was required to test the learner on their ability to remember word pairs and administer electrical shocks for incorrect responses, starting at 15 volts and increasing in 15-volt increments up to 450 volts
