Is Free Will an Illusion?

Don’t trust your instincts about free will or consciousness, experimental philosophers say.

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 past—or they are ­random.

Our intuitions about free will, however, challenge this nihilistic view. We could, of course, simply dismiss our intuitions as wrong. But psychology suggests that doing so would be premature: our hunches often track the truth pretty well [see “The Powers and Perils of Intuition,” by David G. Myers; Scientific American Mind, June/July 2007]. For example, if you do not know the answer to a question on a test, your first guess is more likely to be right. In both philosophy and science, we may feel there is something fishy about an argument or an experiment before we can identify exactly what the problem is.

The debate over free will is one example in which our intuitions conflict with scientific and philosophical arguments. Something similar holds for intuitions about consciousness, morality, and a host of other existential concerns. Typically philosophers deal with these issues through careful thought and discourse with other theorists. 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.

Unknown Influences

To discover the psychological basis for philosophical problems, experimental philosophers often survey people about their views on charged issues. For instance, scholars have argued about whether individuals actually believe that their choices are independent of the past and the laws of nature. Experimental philosophers have tried to resolve the debate by asking study participants whether they agree with descriptions such as the following:

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 making—and 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.

Is Consciousness Just a Brain Process?

Though a young movement, experimental philosophy is broad in scope. Its proponents apply their methods to varied philosophical problems, including questions about the nature of the self. For example, what (if anything) makes you the same person from childhood to adulthood? They investigate issues in ethics, too: Do people think that morality is objective, as is mathematics, and if so, why? Akin to the question of free will, they are also tackling the dissonance between our intuitions and scientific theories of consciousness.

Scientists have postulated that consciousness is populations of neurons firing in certain brain areas, no more and no less. To most people, however, it seems bizarre to think that the distinctive tang of kumquats, say, is just a pattern of neural activation.

Our instincts about consciousness are triggered by specific cues, experimental philosophers explain, among them the existence of eyes and the appearance of goal-directed behavior, but not neurons. Studies indicate that people’s intuitions tell them that insects—which, of course, have eyes and show goal-directed behavior—can feel happiness, pain and anger.

The problem is that insects very likely lack the neural wherewithal for these sensations and emotions. What is more, engineers have programmed robots to display simple goal-directed behaviors, and these robots can produce the uncanny impression that they have feelings, even though the machines are not remotely plausible candidates for having awareness. In short, our instincts can lead us astray on this matter, too. Maybe consciousness does not have to be something different from—or above and beyond—brain processes.

Philosophical conflicts over such concepts as free will and consciousness often have their roots in ordinary intuitions, and the historical debates often end in stalemates. Experimental philosophers maintain that we can move past some of these impasses if we understand the nature of our gut feelings. This nascent field will probably not produce a silver bullet to fully restore or discredit our beliefs in free will and other potential illusions. But by understanding why we find certain philosophical views intuitively compelling, we might find ourselves in a position to recognize that, in some cases, we have little reason to hold onto our hunches.

    My favourite saying is “Nothing is true, everything is permitted” sure its from a game but I still think its valid 🙂 look up its meaning and tell me what you think 🙂

    I agree that there is no absolute truth.

    However I think that ” “your freedom ends where another’s begins” and that we should respect other’s rights.
