" "We live in the era of the “bottom line” mentality, with TED talks, sound bites, and news summaries. There is so much information to digest, we can only hope to grasp the world with compact and seemingly complete stories. We don’t want to be left dangling.
We are all suckers for this information diet, and we all have come to depend on it, just like we have all succumbed to the instant gratification of texting and cell phones. And yet what separates the dilettante from the sophisticate is the appreciation that everything is not simple. The trick seems to be able to talk clearly while remaining fully aware of the underlying complexity of any story. For me it is the overwhelming realization that when trying to figure out how the brain does its masterful trick of
enabling minds, we are barely at the starting line. Dig as deep as you want into human history: As long as there is a written record of thought, there is a record of humans wondering about the nature of life. It becomes obvious that all of us are just hopping into an ongoing conversation, not structuring one with a beginning, a middle, and an end. Humans may have discovered some of the constraints on the thought processes, but we have not yet been able to tell the full story.

There was another major phase of split-brain research where we studied the patients as a way of getting at the other questions very much alive in neuroscience, everything from questions about visual midline overlap to spatial attention and resource allocations. At this point the split-brain patients provided a way of examining cortical-subcortical relationships, and other matters.
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.
