In a follow-up obedience experiment, milgram used 40 new "teachers" and a learner with a "slight heart condition" to determine if participants might have obeyed as much as they did simply because the earlier learners' protests were not convincing. once again, however, the new teachers complied fully percent of the time.

Approximately 65% of participants gave other participants extremely high shocks when told to do so by an authoritarian figure. This number is disturbing because if the shocks were real, the people receiving the shocks would be in intense pain, and potentially even mortal danger. This experiment is often used to show that "average" people can become monsters under the right circumstances.
