The Graph shows a type of heuristic and thinking process that can be used by  Systems Thinkers to solve problems. It is particularly suited when the systems investigated are intangible entities, such as a health system, political parties or ecosystems. The observation leads to the construction of a mental model of the perceived phenomenon and serves primarily to gain  understanding and to guide possible interventions.  Although the mental model can be represented as a causal-loop-diagram, it does not suggest a truthful representation of the observed phenomenon that led to its creation. In fact, when it comes to intangible entities it is impossible to know if the model created by the observer(s) represents an actual entity out there and to what degree it might be truthful. However, having a precise and truthful representation of the phenomenon or situation modelled is not necessary for the model to be useful and to guide practical interventions.  This is confirmed by the ideas of the German philosopher Hans Vaihinger. Vaihinger speaks of ‘useful fictions’ and shows how useful hey can be useful to navigate in the world- and, of course,  deal with complex situations. Here is a link:  https://en.wikipedia.org/wiki/The_Philosophy_of_%27As_if%27

There is a thin broken line in the graph from ‘GAP  to the investigated phenomenon.  This link symbolizes the notion that only a useful viability can be attributed to the model. This viability can be established (or not)  via small intervention applied iteratively to the real-world situation. The model may well turn out to be a very useful fiction.  

When evidence is complex, incomplete, or emotionally threatening, people tend to accept stories that are plausible enough and meaning-creating, even if they are factually weak.

THE CAUSAL LOOP DIAGRAM (CLD) ILLUSTRATES A SOCIALLY DRIVEN DYNAMIC:

* Greater uncertainty increases the need for meaning, which leads to the acceptance of plausible stories.

* Once the story becomes identity-relevant, challenges to it are seen as a threat.

*  Social repetition substitutes evidence.

Perspective taking reveals aspects of complex systems.  This is a natural starting point for systemic investigations, since one can only see aspects of complex systems and never the entire system. The graph shows that investigating these aspects to get a deeper understanding requires  examining them through appropriate interpretive concepts of which systems thinking has many to offer. However, not all systems thinking methodologies concentrate on the investigation the dynamic feedback mechanism of systems. Systems thinking methodologies that ignore feedback mechanisms  do  not possess  a suitable contextual vocabulary for their investigation, and as a result do not offer any advantage over other  investigative methodologies when it comes to investigating the dynamic systems that are traditionally the target of systemic investigation.
