Investigations into the relationships responsible for the success and failure of nations. This investigation was prompted after reading numerous references on the subject and perceiving that *Why Nations Fail: The Origins of Power, Prosperity, and Poverty* by Acemoglu and Robinson seem to make a great deal of sense.

Based on Toward a General Theory of Societal Collapse which references Tainter's Model.

Faced with a performance gap the two most obvious responses are to work harder or work smarter. There are trade offs associated with each, some obvious, some not so obvious.

The establishment of a goal is one way to provide a basis for results thought is has its difficulties.

Success to the successful archetype represents two reinforcing structures which may be in a delicate balance though as soon as one gains a small advantage the resource allocation favors the more successful and the result is then rapidly skewed in the direction of the more successful. See also Archetypes.

There are numerous influences which work against the possibility of sustainable capitalism though there are a few that might be put in place to actually support its emergence.

It's relatively well understood that you can't be all things to all people. Somewhere one has to make choices. An Attractiveness Principle Systems Archetype is essentially a Limits to Growth Systems Archetype with multiple limits, all of which can not be addressed equally. See also Archetypes.

The delays associated with adjusting the shower is a very common example of the Balancing Loop with Delay Systems Archetype.

Two goal seeking structures attempting to resolve and based on the delay one may tend to settle for less. See also Archetypes.

Thoughts on why storytelling is critical for enabling others to understand relationship models once they're developed. This was done for the Learning Community Group at ODU Mar 2019.

A small change in one variable can have a marked impact on multiple variables. Run the model (with height=0)  and consider the output. What happens if  you change to height=5. Run the model to find out. Was the change what you expected?

There are about fifteen known archetypes with an interesting set of relationships among them.

Escape behavior often results in more stress than one escapes from.

The city of Bergen has a goal of becoming fossil-free in 2030. How do we get there? Some weeks ago, local experts from different domains came together and developed a causal loop diagram (CLD). This will form the skeleton for the modelling hackathon.
