It is amazing how a single post by the right person can stir up so much commentary. The latest I have read is One head is better than two or more. As Patricia pointed out in a comment to my previous post on this, The Medici Effect author also goes on to say:
“So, should we all stop brainstorming? I don’t think so. Done right, brainstorming is a highly effective way to actively generate intersectional ideas.”
Brainstorming, like any other human-centric activity, needs a process. Throwing a bunch of people into a room and saying “create brilliant ideas” is not an effective process. To me, this is analagous to putting a bunch of programmers in a room with no process and saying “create a wonderful product” (though admittedly, I have seen a fair number of companies try to do software development this way!). Similarly, badly run, pointless meetings with no clear purpose, and no process, do indeed make us collectively dumber.
Anyone who has ever been on an over-acheiving team (work, sports, or otherwise) knows from experience that the right team, working together with an effective process, can achieve things that none of the individuals could come close to working seperately.
Undertaking any group activity, whether brainstorming, software development, or running a business with no process or a bad process will indeed frequently lead to the result that working alone is more productive and more satisfying than working in a group. Does that mean you stop the activity? No, it means you fix the process.
