Interesting article. The obsession with brainstorming boils down to insecurities and accepted patterns. People tend to feel insecure about their ideas, or their ability to come up with innovative ideas. True innovative ideas are rare. It’s the combining of existing concepts which creates most novel concepts. (So, a group action — combining expertises, and knowledge — might still create more balanced ideas).
People just love patterns. They provide a warm fuzzy feeling of security. It’s the same as breakfasting a full English every day of your life. So, it’s not strange that we take a firm hold of the patter brainstorming and run with it.
Thanks for the insight, perspective and referral to the research.
