What type of feedback does a Negative Feedback Loop provide in cybernetics?

• A. Encourages deviation and change
• B. Reduces deviation and maintains the system's status quo
• C. Eliminates unnecessary communication
• D. Creates new feedback channels

Answer: (B)

A Negative Feedback Loop in cybernetics is designed to reduce deviation from a desired state or setpoint, helping to maintain equilibrium within a system. When a system experiences a shift away from its established norms or targets, the negative feedback mechanism activates to counteract that shift, bringing the system back to its original state. This is evident in various biological and mechanical systems where homeostasis or stability is crucial. For instance, in temperature regulation, when the body's temperature rises above the normal range, mechanisms such as sweating are activated to cool the body down, thus reducing the deviation from the ideal temperature. This function is essential for systems that need to preserve a certain balance, highlighting the role of negative feedback in maintaining the status quo and ensuring stability over time. This understanding is crucial for those studying systems theory and cybernetics in various fields, including psychology, engineering, and biology.
