" Complex and unpredictable
The claims work best in well-ordered situations. Well-ordered domains are structured and stable. We know what causes the effects we want to achieve. We can think systematically about well-ordered domains because we know how they work. We can calculate what decisions to make and how to predict the future.
However, we don't usually live in that world of clarity. Much of the time we find ourselves in a different world-a world of shadows where we don't know all the causes or how they work, we can't pin down all the knowledge we need in order to be successful, and we aren't sure we understand the goals.
