Positive feedback is a process in which an initial change in a system leads to further changes in the same direction. This can occur in various contexts, such as in biology, where the release of a hormone can stimulate more hormone production. In this way, positive feedback amplifies the effects of the initial stimulus, creating a cycle that can lead to significant changes. In technology, positive feedback can be seen in social media algorithms. When a post receives likes and shares, the algorithm promotes it further, increasing its visibility. This creates a snowball effect, where the initial engagement leads to even more interaction, demonstrating how positive feedback can enhance outcomes in different systems.
