As we learn more about how brains work, traditional views can be called into question. Recent research indicates that (at least some) decision-making processes are “prepared” by the brain unconsciously several seconds before there is an awareness of having come to a decision.
“In the study, participants could freely decide if they wanted to press a button with their left or right hand. … The researchers found that it was possible to predict from brain signals which option participants would take already seven seconds before they consciously made their decision.”
I was somewhat surprised by this finding, and look forward to follow-up research as well as independent confirmation. But most of my surprise was not due to the study itself, but rather how the results were interpreted as evidence against the existence of free will.
