DEVIATION AMPLIFYING FEEDBACK
Positive feedback. A circular causal process which may start from an initially unstable (see stability) condition after which the difference between the value of a variable and that condition progressively increases. E.g., underlying an arms race may well be the two countries' desire for peace but a kernel of distrust in the other's motivation to be satisfied with the balance of military power induces an imbalance into the equation which stimulates the production of more and more powerful weapons on both sides, seemingly without end (see runaway). Deviation amplifying feedback either disintegrates the system giving rise to it, runs to a new limit (see morphostasis), or necessitates structural changes (see morphogenesis). (Krippendorff)
