Contrary to what psychiatrists, college students, and middle-class adults predicted, the majority of Milgram’s subjects did not refuse to obey by the 150-volt level of shock. As this table shows, 14 of Milgram’s 40 participants (35 percent) refused to continue at some point after administering 300 volts to the learner. However, 26 of the 40 participants (65 percent) remained obedient to the very end, administering the full 450 volts to the learner.
