Well, half right (disclaimer: not sure on the other half). In Daniel Goleman's latest book, "The Brain and Emotional Intelligence: New Insights", he said something so interesting that I decided to come out of my cave (i.e., living a really social life) and write a blog post:
Lower in the brain, below the limbic areas, lies a neural network called the basal ganglia. This is a very primitive part of the brain, but it does something extraordinarily important for navigating the modern world.
as we go through every situation in life, the basal ganglia extracts decision rules: when I did that, that worked well; when I said this, it bombed, and so on. Our accumulated life wisdom is stored in this primitive circuitry. However, when we face a decision, it's our verbal cortex that generates our thoughts about it. But to more fully access our life experiences on the matter at hand, we need to access further inputs from that subcortical circuitry [where our basal ganglia lies]. While the basal ganglia may have some connection to the verbal areas, it turns out to have very rich connections to our gastrointestinal tract--the gut. So in making [a] decision, a gut sense of it being right or wrong is important information, too."
Turns out, all of our decisions have an emotional component to them. Earlier in his book, he mentions a study done in which a highly successful and intelligent lawyer had to undergo brain surgery to get a tumor removed. This surgery marked a turning point in his life: he went on to lose his career, his marriage, and move in with a family member. However, he was just as intelligent as he once was.
Turns out, during the surgery, a certain part of the connective tissue in the brain was cut in order to reach the tumor. He can't attach feelings to decisions, so he was unable to determine simple things such as what time would be best to make the next appointment for his study.
CHRIST!! Why is our decision making and personality so tied into our biology? One more point for free will being an illusion :/
Anyways, I encourage you to download the ebook or print version of this book. Great stuff, as you can tell.
