Why brainstorming in a meeting often produces worse ideas
Group brainstorming suffers from anchoring, status pressure, and speaking queues. What works better: think alone first.
Brainstorming is considered the standard way to come up with ideas. But research repeatedly shows that people who think alone and then pool results produce more and better ideas than the same people in one room.
What gets in the way in the room
Anchoring. The first idea voiced sets the frame. Others start variations on the theme instead of fundamentally different options.
Status pressure. If the manager speaks first, it feels awkward to propose the opposite. Ideas adapt to the strongest opinion.
The queue. At any moment one person speaks. Others wait and forget what they wanted to say, or bend the thought to fit the flow of conversation.
Evaluation too early. An idea gets judged before it develops. A weak lead that could have grown into something good dies at the first grimace.
Social loafing. In a group it is easier to underperform: someone else will come up with it.
What works better
- Write first, individually. Give 10 minutes: everyone writes ideas without showing others.
- Then gather and discuss. Read ideas anonymously so status doesn’t matter.
- Separate evaluation from generation. Collect everything first, then select.
- Add an async phase. Part of generation can leave the meeting: let people think for a day and add ideas to a shared document.
Where this is convenient
A shared document in Branzy notes suits collecting ideas: blocks, checklists, voice notes for those who find it easier to talk a thought through. The best ideas then become tasks via /task so they don’t remain words.
A meeting is good not for inventing but for choosing among what has already been invented and agreeing on the next step.
