(Choke Points)
Line 7: Line 7:
All manner of phenomena - epidemics, traffic, even politics - move through tiny choke points, seemingly inconsequential bottlenecks that may shape the very direction of history. They are points in history where small shifts cause huge effects. A single event can cause huge effects for several reasons: it can trigger for example a major conflict or war which was already "in the air", or it can be multiplied by some kind of amplification. Frozen accidents occur if a process is [[Path Dependence|path-dependent]] and are often the result of positive feedback. Small fluctuations or accidents at the beginning can be reinforced through the positive [[Feedback|feedback]] process to large, unpredictable deviations, until they are finally conserved for a long time in the resulting frozen '''lock-in state''', where one product dominates and allocates the entire system (for example a market).

: "In the world of dynamical systems, from a mathematical standpoint, feedback loops, especially in complex systems, can be really scary. Because of their unintended consequences. They can create all the beauty and richness in the world around us as well as unforeseen horrors."
