Klappentext

Positive feedback, sometimes referred to as "cumulative causation", refers to a situation where some effect causes more of itself. A system undergoing positive feedback is unstable, that is, it will tend to spiral out of control as the effect amplifies itself. Technically, a system exhibiting positive feedback responds to perturbation in the same direction as the perturbation. That is, "A produces more of B which in turn produces more of A". In contrast, a system that responds to the perturbation in the opposite direction is said to exhibit negative feedback. These concepts were first recognized as broadly applicable by Norbert Wiener in his 1948 work on cybernetics.
