What peak voltage level did a majority of participants reach in Milgram's study?

In Milgram's study on obedience, the majority of participants reached the maximum voltage level of 450 volts. This was a significant finding, as it illustrated just how far individuals would go in following orders, even when those orders led to delivering what they believed were harmful electric shocks to another person. The experiment was designed to demonstrate the extent to which ordinary people would obey authority figures, and reaching the 450-volt level was indicative of the powerful influence that perceived authority can have over individuals' actions. The design of the study, including the escalating voltage levels, led many participants to continue administering shocks despite their discomfort, ultimately culminating in the highest voltage level of 450 volts. This finding has been pivotal in understanding aspects of compliance and moral conflict in psychological research.
