pjt111 taylor on 15 Sep 13Caveat: written by Jonah Lehrer, whose star has fallen since it was shown that he recycled his own previous writing without noting it and he quoted people who other people, not him, had interviewed. Messages: K. Sawyer -- "Decades of research have consistently shown that brainstorming groups [who were told not to criticize anything proposed] think of far fewer ideas than the same number of people who work alone and later pool their ideas." Research by Nemeth -- Groups told that "most studies suggest that you should debate and even criticize each other's ideas" produced more ideas together and then subsequently on their own. Research by Uzzi -- (Lehrer's words) "The best Broadway shows were produced by networks with an intermediate level of social intimacy." Lehrer's take-home message -- "The fatal misconception behind brainstorming is that there is a particular script we should all follow in group interactions. The lesson of Building 20 is that when the composition of the group is right-enough people with different perspectives running into one another in unpredictable ways-the group dynamic will take care of itself. All these errant discussions add up."
