Positive feedback loops enhance or amplify changes; this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes; this tends to hold a system to some equilibrium state making it more stable.

A feedback loop is a process in which the outputs of a system are wholly or partially circled back and used as inputs in the system. The term was first used in the fields of technology and electrical engineering.

A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction. If we look at a system in homeostasis, a positive feedback loop moves a system further away from the target of equilibrium.

The feedback loop is a communication technique that involves both parties in the conversation having a chance to provide feedback, ask questions, and clarify misunderstandings. It's a two-way process that ensures that both parties understand what is being conveyed.
