Stimulus-Response Model
We are embedded in a larger system and unless we realize it an act accordingly we are likely to be the victim of it. From

The Larger System
An infinite number of mathematicians walk into a bar. The first one tells the bartender he wants a beer. The second one says he wants half a beer. The third one says he wants a fourth of a beer. The bartender puts two beers on the bar and says “You guys need to learn your limits.” From

An escalation structure results from two or more competing entities with the competition taking them to somewhere none of them want to be. See also Archetypes.

While it's rather straight forward to invest money in places that generate interest over time why isn't that more of us don't do that and become rich?

Why We're Not All Rich
A system is an entity that the existence of which is maintained via the mutual interaction of its parts and which demonstrates characteristics not exhibited by any of its parts.

Causal loop diagrams are more rigorous than rich pictures though are still only contain a very few elements with well defined rules for connecting them.

Causal Loop Diagrams
Our actions are based on our beliefs and the results of those actions are the basis for our beliefs. The difficulty we create for ourselves is that we make assumptions as to how to interpret the results we select based on our beliefs. As a result we are often operating on a flawed perspective of reality.

When the typical approach doesn't work we tend to rely on our tried and true problem solving approaches, which as you will see really aren't that good.

Politics Makes Us Stupid by Ezra Klein I though I had discovered a new archetype though it's really just a simple reinforcing structure, or so it seems.

Analysis
There are things we can influence and usually a broader array of things we are concerned about though can't influence. It's important to know the differerence otherwise we waste our energies trying to change things we have no influence over.

This model introduces the S/O and +/- notation for depicting the relations that might exist between two elements along with why the +/- notation is preferred.
