Tom Woodward on 20 Apr 15No citation but worth looking at . . . "Claims about the success of brainstorming rest on easily tested assumptions. One assumption is that groups produce more ideas than individuals. Researchers in Minnesota tested this with scientists and advertising executives from the 3M Company. Half the subjects worked in groups of four. The other half worked alone, and then their results were randomly combined as if they had worked in a group, with duplicate ideas counted only once. In every case, four people working individually generated between 30 to 40 percent more ideas than four people working in a group. Their results were of a higher quality, too: independent judges assessed the work and found that the individuals produced better ideas than the groups. "
