Amid great anticipation, Giacomo slowly lowered the electrode into the callosum. As is commonly done in neurophysiology, the recording system was hoo… - Michael S. Gazzaniga

The brain has millions of local processors making important decisions. It is a highly specialized system with critical networks distributed throughout the 1,300 grams of tissue. There is no one boss in the brain. You are certainly not the boss of the brain. Have you ever succeeded in telling your brain to shut up already and go to sleep?

This great zone of cerebral activity is where plans are made to speak, write, throw a baseball, or pick up a dish from the table.

You would not infer causality at all. Not only do you not infer that your neighbor is angry because you left the gate open and her dog got out, you don’t infer that the dog got out because you left the gate open. You don’t infer that the car won’t start because you left the radio on. While you would be good at spatial relations, you would not grasp the causes and effects described by physics. You will not infer any unobserved causal forces, whether they be gravitational or spiritual. For example, you would not infer that a ball moved because a force was transferred to it when it was hit by another, yet because of your inability to draw inferences, you would do better in Vegas at the gaming tables. You would bet with the house and not try to infer any causal relationship between winning and losing other than chance. No lucky tie or socks or tilt of the head. You would not string out some cockamamy story about why you did something or felt some way, not because you aren’t capable of language, but again because you don’t infer cause and effect. You won’t be a hypocrite and rationalize your actions. You would also not infer the gist of anything, but would take everything literally. You would have no understanding of metaphors or abstract ideas. Without inference you would be free of prejudice, yet not inferring cause and effect would make learning more difficult. What processing comes bubbling up in your separate hemispheres determines what the contents of that hemisphere’s conscious experience will be.
