In 1961, social psychologist Stanley Milgram famously conducted a study in which people labeled "teachers" were instructed to administer electric shocks to people in another room, labeled "students," when they answered questions incorrectly. The "teachers" were instructed to administer higher and higher levels of electrical shock, and heard what they believed were cries of pain from the room containing the "students."
In reality, there were no shocks. Milgram claimed that 65% of all "teachers" were finally convinced to administer a final, very painful "shock" to the "students" despite their discomfort with doing so. Milgram linked his results with the concept of "blind obedience" to authority, specifically explaining the behavior of Nazi war criminals during the Holocaust. According to Milgram, many individuals who would normally have been reluctant to cause harm to other people did so anyway, responding to the authority and commands of those above them in the Nazi regime.
Recently, Milgram's study has been reassessed. Which of the following, if true, would NOT call into question the results of the study?
