Nope, being in a group just makes it harder to brainstorm. This has been proven over and over. The correct technique is to define the problem together, then each person alone develops solutions via brainstorming / investigation, then the team meets again and everyone discusses their findings.Having everything happen in a group setting discourages people from sharing their ideas after two or three members start agreeing with each-other because of the unconscious social pressure to fit in

What’s wrong with a small brainstorming meeting?

I'm certainly more innovative when it's the opposite. When you're all on the same page from the beginning and you're deliberating in that way, you will often end up following a very narrow path. Divergence and ideation happens when you're given an initial problem and you attempt to solve said problem independently. THEN you come together and you can start to fashion together a solution, synthesizing the best parts of each solution. Even if someone is completely off the m

Interesting idea, but wouldn't it lead to groupthink and prevent outliers from pushing the envelope?

The article mistakes more ideas for better ideas. The benefit of working in a good group is not that you get more ideas, but that you take the ideas that you get, prune the bad ones and combine the good ones to come up with the 'best' idea. If 'mutual respect' or 'fear of looking stupid' gets in the way of suggesting something while working in a group (as it quite often does) then you need to work on overcoming that fear (individually) and improving your rapport (as a group)Now if they cou

The evidence suggests that brainstorming doesn't work so well - the loudest and earliest views tend to dominate.Instead, the recommendation seems to be to allow people to generate ideas in silence first. This is my approach, which has worked very effectively in groups of up to a dozen remotely for a variety of questions:https://www.ma

Group brainstorming is useful for creating a domain set of ideas to test and kill, especially if a simple-ish or vague problem needs to be solved immediately when optimal soon isn't required. Multiple people together can sometimes create better ideas through on-the-fly refinement. But, people who are less assertive aren't able to make their voices heard or convince others about alternative ideas.Independent contributors have the potential of submitting better ideas privately utilizi

Wow just at a time I was considering this. So currently in a workshop doing an evaluation with a group of people and the amount of group think that starts to occur is unbelievable. You notice it when people start ignoring relevant information. So wrote the problem down and came up with a solution of doing a split between: 1-formulate your own ideas. 2. Then meet and discuss.Based on this maybe ideal maybe 1. Formulate own ideas 2. Meet 3. Forumulate own ideas 3. Meet
