Bipolar II dynamics
In this simulation an afflicted individual with Bipolar II disorder is put to treatment after 20 months the calibration of the medicine or treatment he recieves is such that it simulates the natural cycles of a "normal being". You can note by manipulating the parameters that sometimes too much treatment disrupts equilibria. Also note that in the state diagrams there are 2 limit cycles, the lower one being the healthiest as there are less changes.

The dynamic that prevents confronting climate change
The fact that we all strive to reduce psychologically inconsistent thoughts is a well-researched phenomenon. When we hold two conflicting thoughts in our heads we feel an overwhelming desire to reduce this conflict. This desire can be a powerful driver in the way we behave. Most of us are aware at some level that if we took the threat of climate change seriously we would need to completely change our routines and the way we behave. Flying off on holiday would be out of the question. Swimming pools would be a past luxury. Most of us would need to give up our cars and become vegetarians. The list can be extended almost endlessly. Very often, subconsciously, we try to reduce troubling and inconvenient facts by minimizing, ignoring or even by denying them. Could this be why we hardly talk about climate change even in the face of increasingly frequent extreme weather events and obvious signs that it is occurring now?
This subject needs to be openly talked about between us and in the press. The seriousness of global warming makes it a necessity. Only when this happens will politicians have the space and incentive to act on our behalf. But before this can happen we need to be aware of the reason why we avoid talking about this subject – this graph tries to illustrate the harmful dynamic that could be responsible for it.
This model encodes both hierarchy relationships (brain and senses are part of an individual's body, which is, in turn, part of the environment), as well as causal relationships.
The hierarchy is containment and is represented by nested folders. The environment is modeled as a folder containing all objects of interest, including the individual's body as a whole system. The individual's body is modeled as a folder containing a brain and senses. The individual's body folder is contained inside of the environment folder to represent the idea that the individual's body is contained in, and is a part of, the environment.The brain object and senses objects are contained inside the individual's body folder to represent that the brain and senses together form an object and process that is internal to the individual's body (that is, is contained inside the individual's body and are part of the individual's body).
