The psychological dimension of managing risk is of crucial importance, and its study has led to the identification of specific dos and donts. Those with an understanding of the psychology underlying risk and the skills to recognize its manifestation in practice, have the opportunity to develop frameworks that embody the dos and donts, thereby producing sound judgments and good decisions. Those lacking the understanding and the skills are destined to be more hit and miss in their approach to risk management, doing the donts and not doing the dos. Virtually every major risk management catastrophe in the last fifteen years has psychological pitfalls at its root. The list of catastrophes includes the 2008 bankruptcy of Lehman Brothers and subsequent global financial crisis, the 2010 explosion at BPs Macondo well in the Gulf of Mexico and the 2011 nuclear meltdown at the Fukushima Daiichi power plant. A critical lesson from psychological studies for those involved in risk management is that peoples judgments and decisions about risk vary with type of circumstance. In Behavioral Risk Management readers will learn that there are specific actions that organizations can undertake to incorporate understanding, recognition, and behavioral interventions into the practice of risk management. There are many examples throughout the book that illustrate doing the donts. The chapters in the first part of the book introduce the main ideas, and the chapters in the latter part provide insight into how to apply those ideas to the practical world in which risk managers operate.
