Speaker: 

Despite the increasing centrality of computer software in modern weapons systems, computing remains relatively underrepresented in public debates about weapons policy. For example, in 1991, a software glitch in the Patriot missile defense system killed 28 people, yet physicists remain the most prominent technical critics of this system. This talk suggests that the different patterns of political intervention exhibited by physicists and computer experts cannot be explained by technical relevance. It suggests alternate explanations by examining the processes by which technical judgments are generated and rendered authoritative in the political arena, using insights from science and technology studies. These processes are then illustrated by comparing how computer experts and physicists intervened in political controversy about the feasibility of 'Star Wars', President Ronald Reagan's proposal to develop a missile defense that would render the massive Soviet nuclear arsenal 'impotent and obsolete.' I compare how critical groups of physicists and computer professionals attempted to persuade the public that a perfect missile shield could not be built. This analysis suggests that sharp differences in the two groups' technical frames of analysis, rhetoric, and professional organizations all contributed to the physicists' ability to demonstrate a much higher level of consensus and authority in the political arena.
