Feedback

Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause and effect that forms a circuit or loop. The system can then be said to feed back into itself. The notion
Feedback can give rise to incredibly complex behaviors. The Mandelbrot set (black) within a continuously colored environment is plotted by repeatedly feeding back values through a simple equation and recording the points on the complex plane that fail to diverge.
Positive feedback

Positive feedback is a process that occurs in a feedback loop where the outcome of a process reinforces the inciting process to build momentum. As such, these forces can exacerbate the effects of a sm

…they become even more embarrassed, which leads to further blushing, and so on. Climate science Some effects of global warming can either enhance (positive feedbacks) or inhibit (negative feedbacks) warming. The climate system is characterized by strong positive and negative feedback loops between processes that…
A vintage style regenerative radio receiver. Due to the controlled use of positive feedback, sufficient amplification can be derived from a single vacuum tube or valve (centre).
A phonograph turntable is prone to acoustic feedback.

In sociology a network effect can quickly create the positive feedback of a bank run. The above photo is of the UK Northern Rock 2007 bank run.
