Explicitly dismantling or decommissioning existing sociotechnical systems seems to be unimaginable both within dominant public imaginaries and in academic thought. Indeed, ‘gee whiz’ journalistic narratives regarding emerging technoscience abound as many members of the public appear to eagerly await any new innovation coming out of Silicon Valley. At the same time, most science and technology studies (STS) research focuses on the creation of new technoscience, not its destruction or temporary decommissioning. Yet, lay citizens clearly engage in forms of Luddism: schoolchildren (...) and overworked professionals take digital ‘detoxes’, a number of cities have dismantled their urban highways, and a growing movement of parents have opted their children out of their state’s standardized testing requirements. While all such efforts are rooted in the rejection of a technology, they vary in terms of their resemblance to 19th century English Luddism as well as with respect to Langdon Winner’s concept of epistemological Luddism. How might STS scholars better make sense of 21st century Luddism? This article conceptualizes a number of contemporary examples of technological dismantling with regard to their epistemological and political characteristics. We end with a call for research to better understand lay technological refusal, especially in comparison to elite-driven forms of disruption. (shrink)
