Managing surprise by adversaries when you don’t know what you don’t know. (2014) This presentation addresses the difference in responding to the slow evolution of an adversarial threat versus an adversary with surprises, capturing the importance of diverse blue teams, robustness versus optimation of defense, how surprise happens even to the best planners, and how structures determine the future state of defenders and adversaries.

Strategies in Ecological Evolution with Jen Watkins. (Sept 2007) Text and slides of a presentation at a Complexity Science workshop for the National Alliance for Physician Competence Discovery (NAPCD), a consortium of state physician accreditation organizations across the US (about 25 of them). Background: NAPCD, recognizing that physicians in the future would have to have accreditation based on performance rather than continuing education credits, would have to change how physicians stay in business. NAPCD made extensive progress in developing a physician-client best-practice agreement but reached a mental block to discover what was next. The three-day Complexity Science workshop was organized with the help of Dr. Johnson to present alternative approaches to solving challenges challenges. This talk follows a talk by Lauren Buckley on how ecosystems in nature evolve, addressing how evolving systems express boom and bust cycles (not static growth), which are caused by overly-constrained structures limiting adaptation, and how optimization is the enemy of robustness.
