In recent years, it has become increasingly clear that work in the soc
ial studies of science and technology can be appropriated, or consciou
sly deployed, to serve political ends. Correspondingly, pressure has r
isen on scholars in this field to choose sides in controversies involv
ing science and technology. This paper argues that 'co-production' - t
he simultaneous production of knowledge and social order - provides a
more satisfying conceptual framework than 'controversy' for understand
ing the relationship between science and society, and she scholar's ro
le in that relationship. Political engagement is better achieved throu
gh reflexive, critical scholarship than through identification with ap
parent 'winners' or 'losers' in well-defined but contingent controvers
ies. Reflexivity is especially desirable when selecting sites for rese
arch, styles of explanation, and methods of articulating normative pos
itions.
