Abstract
This chapter envisions a negotiation game which can promote learning, as well as fact-finding on any hot-button issue. The authors outline a particular form of online game, in variants separately designed to work with formal education, working professionals, and the general public. The game, as conceived here, is designed to address a mounting problem in negotiations of the largest scale, public issues: an apparently increasing tendency of people and parties to make up their own facts. Global climate change is considered as a test case.
