It seems obvious to me that I have free will. When I have just made a decision, say, to go to a concert, I feel that I could have chosen to do something else. Yet many philosophers say this instinct is wrong. According to their view, free will is a figment of our imagination. No one has it or ever will. Rather our choices are either determined - necessary outcomes of the events that have happened in the pas - or they are -- random....
In the past decade, however, a small group of philosophers have adopted more data-driven methods to illuminate some of these confounding questions. These so-called experimental philosophers administer surveys, measure reaction times and image brains to understand the sources of our instincts. If we can figure out why we feel we have free will, for example, or why we think that consciousness consists of something more than patterns of neural activity in our brain, we might know whether to give credence to those feelings. That is, if we can show that our intuitions about free will emerge from an untrustworthy process, we may decide not to trust those beliefs....
Imagine a universe in which everything that happens is completely caused by whatever happened before it. So what happened in the beginning of the universe caused what happened next and so on, right up to the present. If John decided to have french fries at lunch one day, this decision, like all others, was caused by what happened before it.
When surveyed, Americans say they disagree with such descriptions of the universe. From inquiries in other countries, researchers have found that Chinese, Colombians and Indians share this opinion: individual choice is not determined. Why do humans hold this view? One promising explanation is that we presume that we can generally sense all the influences on our decision makingand because we cannot detect deterministic influences, we discount them.
Of course, people do not believe they have conscious access to everything in their mind. We do not presume to intuit the causes of headaches, memory formation or visual processing. But research indicates that people do think they can access the factors affecting their choices.
Yet psychologists widely agree that unconscious processes exert a powerful influence over our choices. In one study, for example, participants solved word puzzles in which the words were either associated with rudeness or politeness. Those exposed to rudeness words were much more likely to interrupt the experimenter in a subsequent part of the task. When debriefed, none of the subjects showed any awareness that the word puzzles had affected their behavior. That scenario is just one of many in which our decisions are directed by forces lurking beneath our awareness.
Thus, ironically, because our subconscious is so powerful in other ways, we cannot truly trust it when considering our notion of free will. We still do not know conclusively that our choices are determined. Our intuition, however, provides no good reason to think that they are not. If our instinct cannot support the idea of free will, then we lose our main rationale for resisting the claim that free will is an illusion.
