Behind the headlines of our time stands an unobtrusive army of science advisers. Panels of scientific, medical, and engineering experts evaluate the safety of the food we eat, the drugs we take, and the cars we drive. But despite the enormous influence of science advice, its authority is often problematic, and struggles over expert advice are thus a crucial aspect of contemporary politics. Science on Stage is a theoretically informed and empirically grounded study of the social process through which the credibility of expert advice is produced, challenged, and sustained. Building on the sociology of Erving Goffman, the author analyzes science advice as a form of performance, examining how advisory bodies work to bring authoritative advice to the public stage. This lively and accessible analysis provides not only new insights about science advice but also a fresh look at the social dimensions of scientific writing.
