This proof that our brain try to provide a plausible explanation that has nothing to do with what is happening in reality.

People with brain-split separated brain hemispheres, for example sight and speak capabilities, try to make plausible reasoning that are not grounded. Here is an example From (1) about brain-splitted subject called Joe: In a particularly dramatic recorded demonstration, the famous patient “Joe” was able to draw a cowboy hat with his left hand in response to the word “Texas” presented in his left visual half field. His commentary (produced by the verbal left hemisphere) showed a complete absence of insight into why his left hand had drawn this cowboy hat.
