What is the net effect of positive feedback mechanisms?

The net effect of positive feedback mechanisms is amplification of the original change. Positive feedback occurs when the products of a process enhance or increase that process, leading to a larger and larger output or effect. This is commonly seen in various natural processes, such as childbirth, where the release of the hormone oxytocin increases the intensity of contractions, further stimulating its own release. This results in a significant amplification of the original stimulus until a specific outcome is achieved, such as the birth of a baby.

In contrast, restoration of normal conditions and stabilization of internal conditions are characteristic of negative feedback mechanisms, which work to counteract changes and maintain homeostasis. Reduction of output also aligns more closely with negative feedback processes, which aim to lessen the effects of disturbances to return systems to their set points.
