feedback loop

A thermostat uses a feedback loop to maintain a comfortable room temperature.

Definition

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).

Usage

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).

Examples
  • In technology:
  • In biology:
  • In business:
  • In social media:
Advanced Usage
  • 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.
Variants and Related Words
  • 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.
Synonyms
  • Circular causality
  • Self-regulating mechanism
  • Control circuit
Related Phrases
  • 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.
Related Idioms
  • 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., )
