“Our findings show that debate and criticism do not inhibit ideas but, rather, stimulate them relative to every other condition.”

Nemeth’s studies suggest that the ineffectiveness of brainstorming stems from the very thing that Osborn thought was most important. As Nemeth puts it, “While the instruction ‘Do not criticize’ is often cited as the important instruction in brainstorming, this appears to be a counterproductive strategy. Our findings show that debate and criticism do not inhibit ideas but, rather, stimulate them relative to every other condition.” Osborn thought that imagination is inhibited by the merest hint of criticism, but Nemeth’s work and a number of other studies have demonstrated that it can thrive on conflict.

According to Nemeth, dissent stimulates new ideas because it encourages us to engage more fully with the work of others and to reassess 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 feelings,” she says. “Well, that’s just wrong. Maybe debate is going to be less pleasant, but it will always be more productive. True creativity requires some trade-offs.”

One comment to ““Our findings show that debate and criticism do not inhibit ideas but, rather, stimulate them relative to every other condition.””
  1. I think these findings are spot on. The confusion comes in blurring distinctions between group work ( a more general collaborative organization) and brainstorming ( a specific task that groups can undertake). I would say that criticism while brainstorming is detrimental to that particular task, even though when offered impersonally and effectively criticism is generally healthy for group work.
