The first principle of systems thinking is that structure influences behavior. In other words, "architecture dominates material".
It doesn't mean that we're powerless, on the contrary. By adopting a systems thinking approach, we can better understand the dynamic of the system and find the actions that will have the most leverage.
Linear thinking, A causes B, is not an appropriate model to think about complex systems. Worse, this type of thinking often makes us act contrary to the best interest of the system as a whole.
Unfortunately linear thinking is deeply embedded in our everyday language. We need a new language that restructure how we think.
This new languages focuses on (1) complex relationships, potentially cyclic, rather than linear causal chains, and (2) process of change rather than snapshots.
Often, the system will be steered by adding a negative or positive feedback loop depending on the desired behavior.
Those feedback loops often have delays that make the effects hard to notice.
It is important to distinguish the relationship that are natural laws from human decisions. We can't change natural laws but we can change human decisions.
When two people blame each other they likely are in a destructive feedback loop.
In The Fifth Discipline, Peter Senge presents systems thinking as the foundation to build learning organizations.
