While watching the BBC video on the human mind called The Secret You, Marcus de Sautoy delves into the question of whether our conscious self is responsible for our decisions or if it is our unconscious mind that makes decisions for us. He starts with a simple experiment that explores the source and timing of his choices. It involves Sautoy pressing either a right or left button while lying in a brain scanner that monitors when his brain actually made the decision. After the test, it is revealed that the brain knew what button he would press an astonishing six seconds before he actually pressed it. In other words, Sautoy's conscious decision is secondary to his unconscious brain activity. This leads to the question of whether or not we as human beings are making our own choices, or if this "gray matter" of our brain is. Some questions I have after watching this discovery revolves around those convicted of crimes. Is it possible that people could blame their bad decisions, say murder, on the unconscious activity of the brain? Or do we still have enough control to decide right from wrong, and good from bad? Overall, I found the discoveries of Marcus Sautoy to be very interesting.
