Before we begin, however, l have one more item to add to our toolbox. The relationships between elements in a system are as important as the elements themselves.
Actions often lead to reactions that affect the original actor.
Of the various inputs that contribute to some part of a system, there will always be one that most limits the dynamics of this part. Using these basic concepts, it is possible to model the ebb and flow of cause and effect in surprisingly complex systems. The system will tend to stabilize in a state that is balanced between the various forces. If one player now tries a new strategy to pull the system in his direction, chances are that the other players will soon learn to adjust and move the system back to its original state. For example, when the Romanian government wanted to raise the birth rate, it made abortions illegal.
