Feedback loops are processes where a system’s outputs are fed back as inputs, influencing future behavior. There are two main types:

• Negative feedback loops stabilize a system by counteracting changes (like a thermostat), keeping performance within set bounds.

• Positive feedback loops amplify change, which can lead to rapid growth or instability.

In systems engineering, managing feedback loops is crucial for creating systems that can adapt and potentially become antifragile—improving from moderate stress rather than simply resisting it.
