> [!tldr] 6, 12, 30, and ~150 There is a "best size" for the number of people at gatherings associated with the nature of the event. Trying to force an intimate dinner with 300 people doesn't work. Nor does a March in Washington held by 3. - **six** - deep and intimate conversation & sharing, not often large enough to solicit a multitude of opinions though. Can be prone to groupthink. - **twelve** - about the largest where a group can have *one conversation* where everyone is equal, but large enough to hear multiple perspectives and have a discourse about a diverse thought pool - **thirty** - was mentioned in the book, but honestly I don't remember. This might have been about the biggest group where you can still expect audience members to be able to contribute. - **one hundred fifty** - somewhere between 100 and 200 is about where you can expect everyone there to be able to know each other, really. This corresponds with [[Groups of 150 - Dunbar's Number]]. **** # More ## Source - [[The Art of Gathering]]
