University of Wisconsin-Madison How do laypeople perceive uncertainties about environmental health risks? How do risk-related cognitions and emotions influence these uncertainties, and what roles do sociodemographic and contextual factors, risk judgments, and information exposures play? This study explores these questions using secondary analyses of survey data. Results suggest that uncertainty reflects individual-level emotions and cognitions, but may also be shaped by a variety of social and contextual factors. Emotions (worry and anger) are strongly associated with perceived uncertainty, and perceived lack of knowledge and perceived likelihood of becoming ill are weakly associated with it. Several demographic variables, information exposures, and risk judgment variables affect perceived uncertainty indirectly, primarily through perceived knowledge and emotions. These findings raise a variety of questions about the complex and dynamic interactions among risk contexts, socioeconomic factors, communication processes, perceived knowledge, emotions, and perceived uncertainties about risks.
