Great post. This reminds me of a New Yorker article, Groupthink, from a couple of years ago[0]. Essentially, disagreement fosters creativity, not brainstorming platitudes like 'there are no wrong ideas'.
An excerpt:
...dissent stimulates new ideas because it encourages
us to engage more fully with the work of others and to
reassess our viewpoints. “There’s this Pollyannaish
notion that the most important thing to do when working
together is stay positive and get along, to not hurt
anyone’s feelings,” she says. “Well, that’s just wrong.
Maybe debate is going to be less pleasant, but it will
always be more productive. True creativity requires
some trade-offs.”
1. Thinking on your own can lead to more solutions than thinking in a group.
2. Dissent and constraints stimulate creativity.
3. Insane, off-the-wall, unproductive ideas can stimulate creativity in everyone else.
