There is a lot of discussion about free will and whether humans have it. I don’t pretend to understand all the arguments. I want to learn a lot more in future.
One of the arguments that is made by advocates of the position that humans don’t have free will is based on brain scan results from when people are asked to perform a simple task. For example when someone is asked to move their index finger. Brain scan results show that our brains unconsciously decide to make the finger movement several seconds before we have conscious awareness of the decision. Similar results have been shown for other brain processes. I don’t think the fact that our brains make some decisions in our subconscious, before the conscious brain is aware of them, is in doubt.
Some people posit that this means we don’t have free will. If our subconscious brain is making decisions then how are we making informed conscious decisions is the argument. I don’t agree with this position. Our subconscious is still part of our brains. We don’t fully understand how brains work. Even if we didn’t have the option not to perform the action that is decided in our subconscious (we do have that option), then the decision in the subconscious is still ours.
