👉 The IDs fluid, also known as the Identity Flow or Identity Stream, is a concept from the field of cognitive science and neuroscience that describes how the brain dynamically updates and maintains an internal representation, or "identity," of a person over time. This fluid process allows for the seamless integration of new sensory information with existing memories, enabling us to perceive ourselves as consistent entities despite continuous changes in our physical and mental states. The IDs fluid is crucial for maintaining a coherent sense of self, allowing us to recognize ourselves in mirrors, recall past experiences, and anticipate future actions based on our current identity.
