America’s strict Anabaptist communities (such as the Amish) remain a curiosity in the 21st century. Their commitments to modesty and technological simplicity mark them countercultural, drawing curious onlookers. This chapter considers how members of these strict Anabaptist communities use, reject, and adapt certain technologies to conform with cultural expectations. By regulating technological practice, these communities establish “cultural fences” (Kraybill 2004; Kraybill, Johnson-Weiner, and Nolt 2013). This chapter examines how Amish (and members of other Plain Anabaptist communities) embrace or reject technology. We argue that these dynamics follow the principles of negotiated order (Strauss 1978; Maines 1982). Drawing on Donald Kraybill’s (2001) suggestion that the Amish “negotiate with modernity,” we show how adopting, rejecting, and adapting technology establish symbolic boundaries of Amish identity.
