The Flaw of Averages: Why We Underestimate Risk in the Face of Uncertainty by Sam Savage, John Wiley, 2009, 2012. Describes the pitfalls of average-case analysis and lays out the necessity of Probability Management.
Edited by Gregory S. Parnell, 2016
Presents an integrated trade-off and risk analysis framework to identify value and risk. Examples from defense and commercial domains illustrate these concepts in the different life cycle stages. Chapter 9, includes an Integrated SIPmath Model by Alexander D. MacCalman, Gregory S. Parnell, and Sam Savage to examine Pareto charts, tornado diagrams and distribution functions to perform sensitivity analysis and identify dominant solutions in near real-time.

Embracing the Uncertainty of the Iran Nuclear Deal, Sam L. Savage, ProbabilityManagement.org, September 2015 - Dr. Savage addresses the need to avoid average-based thinking in the Iran Nuclear Deal, and recounts a disaster in an earlier Iran saga. The failed Operation Eagle Claw mission to free the US hostages is still presented as a poster child for the Flaw of Averages by the Naval Postgraduate School. A PowerPoint and Excel model accompany the article.
MIT Sloan Management Review, December 2014 - Psychologists Robin Hogarth and Emre Soyer present the benefits of interactive simulation and the communication of uncertainty, two of the cornerstones of the discipline of probability management. In “Using Simulated Experience to Make Sense of Big Data,” Hogarth and Soyar cite ProbabilityManagement.org as “a non-profit organization that aims at improving communication of uncertainty,” and applies “simulation-based communication to improve actual managerial decisions and public policies.”
