When faced with complexity, it is reassuring to tell ourselves that we can uncover and understand every facet of every problem if we just try hard enough. But that's a fallacy. The better approach, I believe, is to accept that we can't understand every facet of a complex environment and to focus, instead, on techniques to deal with combining different viewpoints. If we start with the attitude that different viewpoints are additive rather than competitive, we become more effective because our ideas or decisions are honed and tempered by that discourse. In a healthy, creative culture, the people in the trenches feel free to speak up and bring to light differing views that can help give us clarity.
