This chapter analyzes the organizational problem of scientific truth, tied again to the dynamics of group culture. The creation of models of truth has been emphasized in science studies, notably in Steven Shapin's A Social History of Truth. But Shapin's analysis is fundamentally normative, examining the rules of truth-telling as set by society. In contrast, the chapter treats verification as an interactional achievement. Forecasters make claims about what the future will bring, but these claims need to be accepted by others.
