FIGURE 11.3 Milgram’s follow-up obedience experiment In a repeat of the earlier experiment, 65 percent of the adult male “teachers” fully obeyed the experimenter’s commands to continue. They did so despite the “learner’s” earlier mention of a heart condition, and despite hearing the learner’s increasingly agonized protests as they administered what they believed were greater and greater voltages. (Data from Milgram, 1974.)
