A minute change in one variable can yield a vastly disproportionate change in the system at a later time. It is also difficult, if not impossible, to make exact predictions of how a system will behave in the future. Psychological Type systems are no exception Jung admitted that it is sometimes impossible to determine a person s true Type. If Type is viewed as a system, then the interdependency between the components of a Type system creates a recognizable identification, or pattern, that separates the system from its environment. The point of transition from system to environment is the boundary of the system.
Outer walls provide the boundary, or pattern, of a house.
Skin provides the physical boundary of the human body and defines the visual pattern of a human. The boundaries of human behavior provide a recognizable pattern of psychological Type. The pattern formed by nonlinear systems is controlled by one or more attractors operating within the system. The movement of a pendulum is influenced by a point attractor trying to bring it to rest in a vertical position. Tornados have a limit cycle attractor that tries to keep the air moving in a circle around the center of the funnel.
