"The Epistemology of War Gaming" - This article from the Spring 2006 Naval War College Review addresses the question of how one can assess the knowledge gained from a war game. Can you extract valid knowledge that will be of use in future, while avoiding drawing unsupported conclusions? This is a fascinating piece, and it ends with a call for a "guild" of war gamers to professionalize the discipline. The author, Robert Rubel, was head of the War Gaming Department at the Naval War College when he wrote this, but has moved up to the position of Dean of Naval Warfare Studies.
I can't find much else on the internet referencing this article, or anything that provides any indication of whether this has prompted the debate that Rubel wanted to start. It's a worthwhile discussion. As I have noted previously, "war gaming" encompasses much more than the seminar-style games I am focused on, but most of the points made here are very relevant to games at the strategic level.
