This new anthology is a comprehensive introduction to the field of risk theory. The introduction provides the ideal starting point for students and professionals new to risk studies and offers a concise refresher for researchers and practitioners. Coverage includes the origins of the 'concept of risk' and its often misunderstood cousin 'uncertainty,' before moving on to address risk perception, risk communication, the idea of trust and post trust as well as risk in policy and regulation with a close look at the Precautionary Principle. Following the introduction, the volume includes a selection of the most significant and influential works on risk in their entirety. These selections, organized thematically to cover the breadth and depth of the field, provide greater detail and elaborate on the key themes and major developments in risk studies. Together they comprise the essential literature necessary for a full understanding of risk theory and practice on any issue and in any context.
