ABSTRACT
Scientific controversies are never just about the “science.” They are social and political struggles over what counts as science, over the authority and credibility of one set of scientific claims versus another, and over the very nature of scientific knowledge itself (see, e.g., Frickel and Gross 2005; Latour 1987; Fuchs 1992; Shapin 1995). They are struggles that produce winners and losersperhaps between scientists and non-scientists, perhaps among competing groups of scientists-in which issues of power and control are never far from the surface.
