I have always rebelled against the tyranny of the usual team meeting dynamics. Yes, there ARE stupid questions! And why capture an idea that we already know is impractical just because the official brainstorming rule is to avoid any criticism? Who made that the rule, anyway?
Turns out research supports this contrarian view: debate and discussion actually do make us more creative.
An excellent article in this week’s The New Yorker, “Groupthink, The brainstorming myth“, by Jonah Lehrer, gives a solid overview of research and examples around the best ways to drive creativity in groups. (Unfortunately you have to subscribe to The New Yorker to see the entire article on that link, so I’ll give a summary.)
Alex Osborn, partner at BBDO, presented brainstorming to the world in his book Your Creative Power, in 1948. His most important rule was the absence of criticism and negative feedback, saying, “Creativity is so delicate a flower that praise tends to make it bloom while discouragement often nips it in the bud.” Brainstorming took off like a rocket, and remains deeply influential to the point of unquestioned dogma.
Yet the research to quantify or disprove brainstorming’s effectiveness date back to 1958, at Yale University. Forty-eight students were told to brainstorm a set of puzzles in groups of four, while forty-eight other students worked solo. The independent students were twice as productive in number of solutions, and were judged to have created solutions that were more feasible and effective.
Subsequent research consistently reinforces that conclusion.
On the other hand, Osborn’s observations from client B.F. Goodrich’s research center that science was best approached in creative teams, has been reinforced in multiple subsequent studies and case studies, most notably in MIT’s Building 20, where a hodge podge of science departments worked side by side and were unusually productive.
What these example all have in common are:
- multiple perspectives and diverse backgrounds working together
- an atmosphere of debate and open challenge to ideas
Charlan Nemeth, at the University of California at Berkeley, demonstrated this effectively in 2003, with 65 undergraduates divided into teams of five. One set of teams followed standard brainstorming rules, one set were advised to debate and even criticize each other’s contributions, and one set was left to their own devices.
The results were telling. The brainstorming groups slightly outperformed the groups given no instructions, but teams given the debate condition were the most creative by far.
Even after the teams disbanded, the individuals in the debate teams continued to come up with more ideas.
According to Nemeth, dissent stimulates new ideas because it encourages us to engage more fully with the work of others and to reasses our viewpoints. “There’s this Pollyannaish notion that the most important thing to do when working together is stay positive and get along, to not hurt anyone’s feeling,” she says. “Well, that’s just wrong. Maybe debate is going to be less pleasant, but it will always be more productive.”
Overall, the lesson seems clear: creativity works best in mixed groups without the constraints of artificial rules of engagement.
Lehrer sums it up, “It is the human friction that makes the sparks.”
