An uncertainty-based risk perspective on risk perception and communication: Opportunities for new empirical-based research.

Risk perception and communication research has to a large extent discussed risk issues on the basis of an understanding of risk as probabilities and expected values. The present article aims at providing some reflections on this research when adopting an uncertainty-based risk perspective, in line with contemporary conceptualizations of risk. This type of perspective sees uncertainty, rather than probability, as a main component of risk, in addition to the consequences and the severity of these consequences. The article shows that this perspective provides opportunities for new research in the field, which can have important impacts on how risk is understood, communicated, and handled in society. Some main challenges for the research are identified and discussed.
