Miracles and Nasty Surprises (MITPress forthcoming) looks at the role of coherence and emergence in organizations.  Coherence is regarded by many psychologists as critical to day to the day productivity and effectiveness of individuals.  Both scholars and managers have adapted this belief to the world of management and organizations.  Coherence is regarded as a sign of a well run organization.  But, the concept of a coherent thought defined as how well an idea holds together as a single entity gradually breaks down as the scale shifts to individuals, groups, and ultimately larger organizations.
