For example, when we want to play golf, Purpose is to play golf. If we can not play golf, this situation is Output. If we can not play golf because of a bad weather, the bad weather is Outside Cause, because we can not change the weather. In contrast, if we cannot play golf because we left golf bags in our home, this cause is solvable. Then, that we left bags in our home is an Inside Cause.
Systems thinking is a very clear and useful method to solve problems.

Contingent thinking Game Theory is a typical contingent thinking method. If we think about as many situations as possible, which may happen, and prepare solutions for each situation, this process is a contingent thinking approach.
