Document Summary
If you see a behavior that persists over time, there is likely a mechanism creating that consistent behavior this is the first hint of a feedback loop. A feedback loop is formed when changes in a stock affect the flows into or out of that same stock. Ex bank balance goes down, you decide to work more hours. Can adjust income (hours working), adjust outflow of cash. Whoever/whatever is monitoring the stock"s level begins a corrective process, adjusting rates of in flow or outflow, and changing the stock"s level (thin curved arrow on diagram=information link) Change is fast at first, then slower discrepancy between stock and goal decreases. The world is full of goal-seeking feedback loops body adjusting blood sugar levels, pulling care to a stoplight. Presence of feedback mechanism doesn"t mean mechanism works well may not be strong enough to bring stock to desired level. Can cause healthy growth or runaway destruction.
