Virtual diversity and the value-ladenness of science

Collins, Evans, and Reyes-Galindo develop the concept of interactional expertise into the idea of virtual diversity. They thereby provide a strong case against the epistemic barriers established by identity politics. This commentary questions, however, whether virtual diversity can incorporate the critique of institutional power that Wynne has argued is at the center of tensions between lay publics and scientific establishments. The commentary argues for a critical theory of science, as suggested by Doppelt on the basis of his normative interpretation of Kuhnian incommensurability.
