"The bottom line of our study is that diversity matters: When team members have more unique information, they make more intelligent decisions. But diversity alone is not enough. A bad information-sharing strategy in the team can leave the important information unsaid. The most efficient and scalable approach for information-intensive decisions is to leverage the wisdom of disagreement. It is by challenging the assumptions and opinions of our team members that we produce collective intelligence, a scarce but sorely needed quality for today’s teams."
