Saw this over on Bruce Schneier's blog, it seemed worth reposting here. Wharton’s “Quake” Simulation Game Shows Why Humans Do Such A Poor Job Planning For & Learning From Catastrophes (link is to summary, not original article, as original article is a bit redundant). Not so sure how appropriate the "learning from" part of the title is, as they don't seem to mention people playing the game more than once, but still quite interesting.
