Constructivist analyses of risk regulation are typically agnostic about what should count as robust or reliable knowledge. Indeed, constructivists usually portray competing accounts of risk as if they were always equally contingent or engaged with different and incommensurable issues and problem definitions. This article argues that assumptions about the equal reliability of competing accounts of risk deserve to be, and sometimes can be, examined empirically. A constructivist approach grounded in epistemological realism is outlined and applied empirically to a particular comparative (...) U.S./u.k. case study of pesticide regulation. The article argues that while the scope for interpretative flexibility when addressing risk issues is clearly extensive, it is not unconstrained. By scrutinizing the structure and coherence of particular risk assessments and policy decisions by reference to both empirical evidence and commonly held robust standards of interpretation, the article argues that the U.K. evaluation was not only less precautionary than its U.S. equivalent, but it was also less well constructed and therefore less reliable. Several social and institutional characteristics of U.S. and U.K. policy making are highlighted that appear variously to facilitate or inhibit the production of reliable knowledge and the making of prudent policy decisions.

This paper provides an analysis of the evolution of thinking and talking about the role of scientific knowledge and expertise in food safety policy-making, and in risk policy-making more generally from the late 19th century to the present day. It highlights the defining characteristics of several models that have been used to represent and interpret the relations between policy-makers and expert scientific advisors and between scientific and political considerations. Both conceptual and empirical strengths and weaknesses of those models are identified, (...) focusing in particular on the ways in which they deal with scientific uncertainties and social choices. By drawing on both empirical evidence and conceptual analysis, a novel and more realistic model is provided along with an account of some conditions for food safety policy-making achieving both scientific and democratic legitimacy.
