Examining uncertainties in government risk communication: citizens' expectations

Abstract

With the shift towards more participative approaches to risk communication and risk management, policymakers are expected to be more transparent with the public concerning existing uncertainties about health risks, such as lack of data or contradictory evidence. There is, however, a debate among researchers as to whether this transparency about uncertainties is indeed welcomed by the public and if it is effective in promoting trust in risk regulatory institutions. The qualitative study on which this article is based aimed to clarify citizens' perceptions of diverse sources of uncertainty in government risk communication and their expectations with respect to discussing uncertainties. Forty-seven adults from two major Canadian cities took part in focus groups or individual interviews in which they voiced their expectations about who should be involved in risk communication, why uncertainties should be communicated, what sources of uncertainties were preferred, as well as how and when these should be discussed. Their discussions showed that they expected the government to include citizens in evaluating and managing uncertainties pertaining to risks under individual control and directly informing consumer choices about health risks. In contrast, they questioned the relevance of systematically exposing uncertainties relating to risks perceived as outside individual control, and associated with very low probability scenarios of possible threats. Globally, they appraised the desirability of discussing uncertainties in risk communication in relation to the perceived utility of the information for decision-making. These findings indicate that risk communicators and managers need to consider ways in which discussions of uncertainties can empower citizens.
