positive feedback

So-called positive feedback has nothing to do with emotional "positive vibes" or "good feelings" but refers specifically and only to that which tends to increase the overall signal amplitude. Such increase tends to be exponential, e.g. the Fibonacci sequence.

Spiral dynamics is based on positive feedback loops as applied to information flow within belief systems or rulesets - when acted upon, these appear to "work" and so reinforce themselves.

However any such loop can still be curtailed or limited by rule shifts which disrupt the flow of the positive or negative feedback, or cause one to ignore the flows - thus becoming ignorant. See GPC unperson for an example of this method of imposing ignorance.
