Free Will vs. the Programmed Brain: Scientific American
In a clever new study, psychologists Kathleen Vohs at the University of Minnesota and Jonathan Schooler at the University of California at Santa Barbara tested this question by giving participants passages from The Astonishing Hypothesis, a popular science book by Francis Crick, a biochemist and Nobel laureate (as co-discoverer, with James Watson, of the DNA double helix). Half of the participants got a passage saying that there is no such thing as free will. The passage begins as follows: "'You,' your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free will, are in fact no more than the behavior of a vast assembly of nerve cells and their associated molecules. Who you are is nothing but a pack of neurons."
The passage then goes on to talk about the neural basis of decisions and claims that "...although we appear to have free will, in fact, our choices have already been predetermined for us and we cannot change that." The other participants got a passage that was similarly scientific-sounding, but it was about the importance of studying consciousness, with no mention of free will.
