because it is so hard to apply. Also, the theory itself does not claim and exact applications other than "reframing". Reframing asks the communicators to step outside of the situation and reinterpret what it means. This can be hard because the theory states that only an outside source can see a problem because people are "speaking their own language". This theory also shows how a relationship has already changed, but it does not give practical ways to go about changing it. This system resists change and it can be hard to actively use the five axioms. Related to the first axiom, non-verbal communication can be viewed as informative rather than communicative. With the behavioral characteristic of equifinality involved, it is hard to know when the system of the Interactional View is happening or not. Equifinality is the systems theory assumption that a given outcome could have occurred due to any or many interconnected factors rather than being a result in a cause—effect relationship. This theory rests on the word communication, but this word can be interpreted very differently between people. The definitions of communication can be very controversial. Overall, the axioms do a great job of explaining problems, but do not provide solutions to the problems they bring up.
