Group brainstorming often fails to maximize collective intelligence due to ego threats, noise, and conformity pressures, leading to a lack of diverse thought and groupthink.
"Brainwriting" is a more effective alternative to brainstorming. It involves individual idea generation, pooling and sharing ideas anonymously, individual evaluation, and finally, team selection and refinement.
Examples, like Dow Chemical's innovation tournament and the Chilean miner rescue, demonstrate the success of brainwriting in bringing forth innovative ideas and solutions.
