Risk communication : towards a rational dialogue with the public

Abstract

Professional risk managers and the general public strongly disagree about the seriousness of many risks. Most members of the public are concerned about long-term effects of risks, inequitable siting, lack of personal control, and the pace of technological diffusion into their cultural envi- ronment, whereas professional risk managers focus on the task to minimize the probability of adverse effects caused by a technology or other human activity. To bridge the gap between the professional mandate and the public perception of risk, a dialogue has to be initiated between risk mana- gers, interest groups and representatives of the affected public. This dialogue should serve the function of reconciling conflicts among various groups. A prerequisite for a successful conflict resolution is the willingness of each group to respect the perspective of all the other partici- pating groups and to include their concerns into the decision-making process. This paper reviews the literature on the three main functions of risk communication: message recognition, inducement of attitude and behavioral changes, and resolution of risk-related conflicts. The paper also discusses the structure of the communication process from a descriptive and a normative point of view, and draws on studies about risk perception and communication to develop some guidelines for successful risk communication.
