"Wondering if people today would similarly obey, Jerry Berger (2009) replicated Milgram's study—though only to the 150-volt point. At that point, 70 percent of participants were still obeying, a slight reduction from Milgram's result. (In Milgram's study, most who were obedient to this point continued to the end. In fact, all who reached 450 volts complied with a command to continue the procedure until, after two further trials, the experimenter called a halt.) However, Berger's participants were more diverse than Milgram's—for example, half were women, unlike Milgram's initial all-male sample. Comparing Milgram's 1962 men to Berger's 2006 men, obedience at 150 volts dropped from 83 percent to 67 percent. In other words, nearly twice as many modern men (33 percent vs. 18 percent) disobeyed, but many still obeyed. Cultural change toward more individualism might have reduced obedience, but far from eliminated it. Even 54 years later, Milgram's obedience paradigm was powerful—just a little less so (Twenge, 2009)."
"Berger and his colleagues (2011) later analyzed their participants' spontaneous comments. Whether people stopped or obeyed was not predictable from their expressing concern for the learner's well-being, which most did, but from their voicing feelings of responsibility for their actions."
"Further, notes Jerry Berger (2014), Milgram's results were not as surprising as they first seem. Four features of Milgram's study design, he argues, mirror well-documented psychological effects:
- the 'slippery slope' of small requests that escalate into large ones,
- the framing of shock-giving as the social norm for the situation,
- the opportunity to deny responsibility, and
- the limited time to reflect on the decision.
All of these, in Milgram's studies and in other research, increase compliance."
