 Finally there is the idea that objectivity is anchored in scientific communities and their practices. After discussing three case studies from economics, social science and medicine, we address the conceptual unity of scientific objectivity: Do the various conceptions have a common valid core, such as promoting trust in science or minimizing relevant epistemic risks? Or are they rivaling and only loosely related accounts? Finally we present some conjectures about what aspects of objectivity remain defensible and desirable in the light of the difficulties we have encountered.
