"The limitations imposed by a game make all the difference, as a UC Berkeley psychology experiment showed. Professor Charlan Namath gave a problem to three groups with three different sets of instructions. The group with instructions similar to traditional brainstorming got slightly better results than a group with little direction. But a group that had a “debate condition” imposed on them generated 25% more ideas.
Gamestorming works by drawing boundaries—like kids playing wiffle ball deciding the doghouse will be first base and a stack of firewood will be second base. When we understand the “ground rules,” we are freed to play—and even compete—in ways that make sense. You never see social loafing and sucker effects in wiffle ball, do you?"
