Die Tücken der Technik: Wenn Fortschritt sich Rächt

If it can go wrong, it will–thus Murphy’s Law. Science journalist Edward Tenner looks more closely at this eternal verity, named after a U.S. Air Force captain who, during a test of rocket-sled deceleration, noticed that critical gauges had been improperly set and concluded, “If there’s more than one way to do a job and one of those ways will end in disaster, then somebody will do it that way.” Tenner concurs, and he gives us myriad case studies of how technological fixes often create bigger problems than the ones they were meant to solve in the first place. The indiscriminate use of antibiotics, by way of example, has yielded hardier strains of bacteria and viruses that do not respond to pharmaceutical treatment; the wide-scale use of air conditioning in cities has raised the outdoor temperature in some places by as much as 10 degrees, adding stress to already-taxed cooling systems; the modern reliance on medical intervention to deal with simple illnesses, to say nothing of the rapidly growing number of elective surgeries, means that even a low percentage of error (one patient in twenty-five, by a recent estimate) can affect increasingly large numbers of people. Tenner examines what he deems the “unintended consequences” of technological innovation, drawing examples from everyday objects and situations. Although he recounts disaster after painful disaster, his book makes for curiously entertaining, if sometimes scary, reading. –Gregory McNamee
