Abstract
In States of Knowledge, Sheila Jasanoff argues that we gain explanatory power by thinking of natural and social orders as being produced together, but she and her volume contributors do not yet offer a theory of the coproduction of scientific knowledge and social order. This article uses Mary Douglas’s cultural theory to identify four recurring states of knowledge and to specify political–cultural conditions for the coproduction of scientific knowledge, social order, and scientific, cultural, and policy change. The plausibility of this theory is illustrated by using it to explain the coproduction and transformation of forest and wildlife science and management in the Pacific Northwest.
