What split-brain experiments revealed about the self

The left hemisphere of the brain contains an "interpreter" that constructs a coherent narrative of our actions and experiences, making us feel unified. Consciousness isn't a linear flow but a convenient story created by the unconscious brain for our "viewing pleasure." This interpreter constantly seeks explanations for our behavior. Studies on patients with disconnected brain hemispheres reveal the left hemisphere's tendency to rationalize actions, even if the underlying cause is unknown to the conscious mind. This suggests our conscious narrative may not be as linear as we perceive. The brain "chunks" information, with the unconscious mind analyzing data to deliver a coherent narrative. Humans are storytelling animals because this system strives for story coherence, even when actions originate outside conscious awareness. Individual experiences shape these narratives, leading to different interpretations and stories. The enjoyment of fiction might prepare us for unexpected life events by allowing us to rehearse responses in a fantasy world.
