The key to staging more productive brainstorming sessions may all be in the preparation, with research pointing to the benefits of ensuring you get conditions right before the actual idea generation commences.
Research outlined by Kellogg School of Management at Northwestern University professor Leigh Thompson in the Harvard Business Review explores how people can be primed for better brainstorming and points to the effectiveness of candour in generating greater creativity.
Thompson and colleagues Elizabeth Ruth Wilson and Brian Lucas conducted a number of experiments in which participants were required to share personal experiences before tackling a brainstorming session.
The first experiment saw one set of participants describe a time they’d felt embarrassed in the previous six months, and a second group describe a time they’d felt proud, with each individual then asked to take 10 minutes to think about new uses for a paper clip.
Thompson writes that the researchers hypothesised that “the ’embarrassing story’ condition would lead people to drop their inhibitions and get more creative”.
Output was measured in terms of idea fluency and flexibility, and the embarrassing stories group lead the way, scoring 7.4 for fluency and 5.5 for flexibility, compared those in the group that had discussed pride, which scored 5.843 and 4.568.
Foibles anecdotes boost brainstorming efficacy
A second study investigated how the same dynamic would work at a group level.
“We suspected that the effects might be magnified if the recounting of accomplishments caused people to worry more about hierarchy and social comparisons, quelling creativity, and if a discussion of foibles (a minor weakness or eccentricity in someone's character) helped people to open up and take more risks, boosting brainstorming efficacy,” Thompson explains.
The researchers randomly assigned 93 managers from a range of companies and industries to three-person teams, with half of the groups told to share embarrassing stories and half talking about times they had felt pride, with the proviso that the stories involved them personally and had occurred in the previous six months.
While the people told to tell embarrassing stories were initially caught off-guard, “within minutes, the trios were laughing uproariously”, while the people told to boast had no trouble commencing their conversations, which were, however, comparatively lacking in laughter.
A brainstorming challenge was introduced after 10 minutes, requiring the participants to generate as many unusual uses for a cardboard box as possible, with the same fluency and flexibility scoring criteria seeing the embarrassing story teams generate 26% more ideas spanning 15% more use categories than their counterparts.
“Candour led to greater creativity,” Thompson writes.
“Thus, we propose a new rule for brainstorming sessions: Tell a self-deprecating story before you start. As uncomfortable as this may seem, especially among colleagues you would typically want to impress, the result will be a broader range of creative ideas, which will surely impress them even more.”
