I think this study is great. It shows that innovative engineering breakthroughs tend to come in small steps, rather than in large leaps.
By recording conversations and analysing them they found that brainstorming sessions work on the principle of ‘Yes and’. One person proposes something, which sparks off the next step from somebody else, and it continues until they reach a completely new idea. An idea they could not have come up with on their own.
That’s group creativity and I think it’s fascinating to see proof of it in technical fields. It is something that I already believed, that ‘creative’ and ‘scientific’ fields are just overlapping parts of the same human endeavour- an enquiry into how the Universe works and what we can do with it.
