Risk Perception and Risk Analysis in a Hyperpartisan and Virtuously Violent World.

I shall discuss, from a personal perspective, research on risk perception that has created an understanding of the dynamic interplay between an appreciation of risk that resides in us as a feeling and an appreciation of risk that results from analysis. In some circumstances, feelings reflect important social values that deserve to be considered along with traditional analyses of physical and economic risk. In other situations, both feelings and analyses may be shaped by powerful cognitive biases and deep social and partisan prejudices, causing nonrational judgments and decisions. This is of concern if risk analysis is to be applied, as it needs to be, in managing existential threats such as pandemic disease, climate change, or nuclear weapons amidst a divisive political climate.
