feedback loop
A thermostat uses a feedback loop to maintain a comfortable room temperature.
Noun: 1. A self-regulating system: A process, system, or circuit in which the output (or result) is used to modify or control the input, creating a cycle of cause and effect. 2. A cause-and-effect cycle: A sequence where information about an action's outcome influences future actions, often leading to amplification (positive feedback) or stabilization (negative feedback).
The term describes a mechanism where information from a process is returned ("fed back") to influence the ongoing operation of that same process. * It is commonly used in engineering, biology, business, and social systems. * It can be a technical mechanism (like in electronics) or a metaphorical concept (like in economics or psychology).

- Positive feedback loop: A cycle where the output amplifies the process, leading to exponential growth or decline. (e.g., )
- Negative feedback loop: A cycle where the output dampens or stabilizes the process, maintaining equilibrium. (e.g., )
- Closed-loop system: A system that automatically uses feedback to control itself without external intervention.
- Feedback (n): The information about a result that is returned.
- Loop (n): A structure, series, or process where the end is connected to the beginning.
- Cybernetics (n): The scientific study of control and communication in machines and living organisms, central to which is the concept of the feedback loop.
- Circular causality
- Self-regulating mechanism
- Control circuit
- To create a feedback loop: To establish a system where outputs influence inputs.
- The new policy unintentionally created a feedback loop of increasing costs.
- To be stuck in a feedback loop: To be trapped in a repetitive, often unproductive, cycle.
- The team was stuck in a feedback loop of meetings about having more meetings.
- Vicious circle/vicious cycle: Similar to a harmful positive feedback loop. (e.g., )
- Virtuous circle/virtuous cycle: Similar to a beneficial positive feedback loop. (e.g., )

- a circuit that feeds back some of the output to the input of a system
