Standard approaches to defining and evaluating environmental risk tend to reflect technocratic rather than democratic values. One consequence is that institutional mechanisms for achieving citizen participation in risk decisions rarely are studied or evaluated. This article presents a survey of five institutional mechanisms for allowing the lay public to influence environmental risk decisions: public hearings, initiatives, public surveys, negotiated rule making, and citizens review panels. It also defines democratic process criteria for assessing these and other participatory mechanisms.

Consensus conferences, also known as citizens’ panels—a collection of lay citizens akin to a jury but charged with deliberating on policy issues with a high technical content—are a potentially important way to conduct technology assessments, inform policy makers about public views of new technologies, and improve public understanding of and participation in technological decision making. The first citizens’ panel in the United States occurred in April 1997 on the issue of “Telecommunications and the Future of Democracy.” This article evaluates the (...) impact of this citizens’ panel. The standard criteria to evaluate the impact of analyses focus on the “actual impact” and on the “impact on general thinking.” To these standard criteria, this article introduces the evaluation of two impacts related to learning: impact on the training of knowledgeable personnel and the interaction with lay knowledge. The impact evaluation is based on a nearly comprehensive set of semistructured telephone interviews with the participants in the panel. (shrink)

The concept of public participation is one of growing interest in the UK and elsewhere, with a commensurate growth in mechanisms to enable this. The merits of participation, however, are difficult to ascertain, as there are relatively few cases in which the effectiveness of participation exercises have been studied in a structured manner. This seems to stem largely from uncertainty in the research community as to how to conduct evaluations. In this article, one agenda for conducting evaluation research that might (...) lead to the systematic acquisition of knowledge is presented. This agenda identifies the importance of defining effectiveness and of operationalizing one’s definition. The article includes analysis of the nature of past evaluations, discussion of potential difficulties in the enactment of the proposed agenda, and discussion of some potential solutions. (shrink)
