Think about it like this: independent decisions give you more information than interdependent decisions. You can look at the success of Gangnam Style, and it seems like people are making a decision to watch the video. But those decisions aren’t independent – they’re interdependent. People are watching because other people are watching, not because it’s necessarily a great song (although it may be).
Within an organization, that means that individuals should be assessing the quality of an idea or product independently -– at least initially. After that, a team can come to a consensus. If you all sit in a room together initially, though, you’re going to lose information because of the effects of social influence.
Ignore the wisdom of crowds and develop your own opinion first.
