Everything Is Obvious_ _Once You Know the Answer - Duncan J. Watts [4]
And yet that’s precisely what happened one day in the early 1970s when a group of psychology students went out into the subway system on the suggestion of their teacher, the social psychologist Stanley Milgram. Milgram was already famous for his controversial “obedience” studies, conducted some years earlier at Yale, in which he had shown that ordinary people brought into a lab would apply what they thought were deadly electrical shocks to a human subject (really an actor who was pretending to be shocked) simply because they were told to do so by a white-coated researcher who claimed to be running an experiment on learning. The finding that otherwise respectable citizens could, under relatively unexceptional circumstances, perform what seemed like morally incomprehensible acts was deeply disturbing to many people—and the phrase “obedience to authority” has carried a negative connotation ever since.1
What people appreciated less, however, is that following the instructions of authority figures is, as a general rule, indispensible to the proper functioning of society. Imagine if students argued with their teachers, workers challenged their bosses, and drivers ignored traffic cops anytime they asked them to do something they didn’t like. The world would descend into chaos in about five minutes. Clearly there are moments when it’s appropriate to resist authority, and most people would agree that the situation Milgram created in the lab would qualify as such a moment. But what the experiment also illustrated was that the social order that we take for granted in everyday life is maintained in part by hidden rules that we don’t even realize exist until we try to break them.
Based on this experience, and having subsequently moved to New York, Milgram had begun to wonder if there was a similar “rule” about asking people for seats on the subway. Like the rule about obeying authority figures, this rule is never really articulated, nor would a typical rider be likely to mention it if asked to describe the rules of subway riding. And yet it exists, as Milgram’s students quickly discovered when they went about their little field experiment. Although more than half of the riders asked eventually surrendered their seats, many of them reacted angrily or demanded some explanation for the request. Everyone reacted with surprise, even amazement, and onlookers often made disparaging remarks. But more interesting than the response of the riders was that of the experimenters themselves, who found it extremely difficult to perform the experiment in the first place. Their reluctance was so great, in fact, that they had to go out in pairs, with one of them acting as moral support for the other. When the students reported their discomfort to Milgram, he scoffed at them. But when he tried to do the experiment himself, the simple act of
