Instinct refers to a natural and inherent behavior or reaction that is not learned or consciously thought out. It is an innate ability possessed by all living beings, guiding them to act in specific ways to ensure their survival or the survival of their species. Instincts are deeply ingrained and can be seen in various forms, such as a baby's instinct to suckle for nourishment or an animal's instinct to hunt for food. These unconscious impulses are often driven by instincts related to protection, reproduction, or self-preservation. Instincts can play a significant role in decision-making and instinctual responses are usually quick and automatic.
