Study Suggests Free Will Is An Illusion (iflscience.com) 386

An anonymous reader quotes a report from IFLScience: A new paper published in the journal Psychological Science has attempted to define and investigate the subject of free will. By asking participants to anticipate when they thought a specific color of circle would appear before them, something determined completely by chance, the researchers found that their predictions were more accurate when they had only a fraction of a second to guess than when they had more time. The participants subconsciously perceived the color change as it happened prior to making their mental choice, even though they always thought they made their prediction before the change occurred. They were getting the answers right because they already knew the answer. "Our minds may be rewriting history," Adam Bear, a Ph.D. student in the Department of Psychology at Yale University and lead author of the study, said in a statement. The implication here is that when it comes to very short time scales, even before we think we've made a conscious choice, our mind has already subconsciously decided for us, and free will is more of an illusion than we think.

    The conclusion is bullshit. Free will isn't an illusion and life isn't a game that plays us. (Anyone catch the reference there?)

    On short time scales, reaction time is probably faster if the brain does some processing in advance. The decision is already made so the mental processing need not be done instantly and, instead, can just be acted upon almost right away.

    At longer time scales, though, there probably is free will. There's no clear advantage to intelligence if free will doesn't exist to make use of it.

    Maybe at short time scales, free will doesn't really exist. Instincts and reflexes take over, though these can be conditioned. At longer time scales, though, free will surely does exist. The brain has more than one way of processing information and deciding on a course of action.

      The problem is how to define 'free will'. You're certainly free to choose your choice... I think anyone who suggests that the output is completely divorced from the input is a bit of a wacko. At the same time, I think our available degrees of freedom are so large that you might as well just take it that we have a good approximation of free will. Makes the question almost boring to be honest. Who cares if we have true philosophical free will? Isn't that the same as arguing that the future does not depend on the past, in the context of humanity but in no other context?

      • Yes, the definition if free will is very much the issue. People mostly believe, especially when using the word "decision", that the conscious mind is making decisions. But recent science says that we do not make conscious decisions. They are made subconsciously, with the conscious merely inventing post-hoc plausible explanations for why that decision has been made, if called on to do so.

        For sure we are reacting to inputs, and getting an output, and the illusion is that the conscious mind that is deciding th

      I often compare the inherent error in the "free will is an illusion" conclusion with a normal decision by committee or an election. We often have a pretty good idea of the result of an election before the actual election happens, but we don't see it as a problem of the free will of the electorate. They still can vote how they want. We often have an idea how a judge will rule in court way before the judge actually presents the ruling, but we wouldn't conclude that the judge doesn't have a free will. We also know that often something is decided early on, but it takes some time until the decision is communicated to the outside just because we want to check, look for possible errors or wait for a result not in yet (and which could flip the decision).

      So yes, we often have pretty good predictors of the outcome of a decision, and it often takes some time for a decision to finalize much later than the predictors already show the outcome, but that doesn't mean the decision wasn't free. And yes, if we don't wait for the decision to finalize, but take the preliminary result for the final result, we could speed up the process considerably.

    The paper (or at least its abstract) doesn't seem to mention "free will". This seems to be a term introduced by reports of the paper. The paper itself seems to refer to choices that are made consciously as opposed to those that aren't (and are therefore made subconsciously). I think the term "free will" confuses the issue, because it's used in different ways.

    In practical usage it more or less refers to choices that are made without being controlled by an outside agent (e.g. not choices made under duress), and in philosophical usage it more or less refers to "choices" that are made without any cause (although I don't think this idea makes sense).

      Subjects were given a very quick preview of the color before they had to pick one. The experiment looks more like subliminal advertising; I suppose the subjects thought they were guessing when in fact they had been tricked into selecting the correct answer without realizing their choice had been biased (hence what they thought was a free will choice wasn't). Not exactly groundbreaking science.

    Our primitive mind designed for a world where we are constantly under attack or will need to attack others, is the product of 500 millions years of evolution. Our higher brain functionally only 2 or 3 million years. So yes in term of making quick decision our primitive brain kicks in. We use it while driving, and every day living. That is why magicians are able to pull off their tricks on us. They get the primitive brain distracted on something else while they do something else. The higher human brain is much slower however it will try to process more information. Such as the question to the volunteers of this study if they want to do it or not. There is no immediate danger there is no pressure of instant response they can stand back and think about it. Factor in what rewards would they get, what are the risks, what trade offs from the action will occur. That is free will. However if someone tried to get volunteers and is a natural sales man would apply pressure on them to make a decision far more quickly. Because they will avoid them trying to think about it, they will keep their minds occupied with idle chit-chat, and implying the positive images of what will happen.
    The study shows our primitive mind makes a lot of decisions for us. But nothing about free will.

    I feel ashamed to think of all the years when I went on believing there was some distinction between predestination and free will. In fact, I'm now sure it's just a matter - once again - of us being fooled by our own language.

    Imagine the universe from a God's eye point of view. Think of it as a four-dimensional space, with one dimension being time. (Physics suggests there are probably a lot more dimensions, but this simple model is sufficient). Now when (apologies for the meaningless use of "when", as time is a dimension within the universe) God creates the universe, it is complete: it contains, in His mind, everything that will ever happen. (Please note that this mental experiment does not depend at all on the existance of God). What does this do to free will? Well, it obviously destroys it completely. Imagine the Mississippi River, which notoriously meanders and turns back on itself for hundreds of miles. It creates curves, which become oxbow lakes, and then disappear again. Do you think the river has free will? Or could all of its elaborate changes be predicted, with enough knowledge of the physics and the initial conditions? Yet maybe if you were the river, you might like to think you had free will.

    There is no contradiction here. We feel as if we have free will, yet our actions are mostly quite predictable. Ask yourself, "who is it that has free will?" Isn't it a rather old-fashioned picture that comes to mind, of a little person or imp sitting inside your head, choosing and making decisions for you? But even introspection shows (as David Hume testified) that there is no such little imp of identity. Our actions arise from the state of the whole organism from moment to moment. And if there seems to be an element of freedom, of indeterminacy, to them that may be because so very much of our thinking is unconscious.

    • My personal feeling that the whole concept of "free will" is purely a matter of philosophical perspective- entirely dependent on how you approach and define certain terms- and as such there can be no meaningful definitive answer as to whether it exists or not.

  • From the abstract... Here, we explore the possibility that choices can seem to occur before they are actually made...The experience of choice is susceptible to “postdictive” influence and that people may systematically overestimate the role that consciousness plays in their chosen behavior.

    Free will is too heavy a term for what's at play here. These methods of study simply show that our freedom of choice does not mean that we choose at random. And that's been studied and experimented with [google.com], debated by philosophers throughout human history [behavior.org], and has popped up even on Slashdot [slashdot.org]. As my first source clearly says, "One of the worst ways to generate 'random' numbers is to ask somebody to write down some numbers 'at random'. It won't work...The human mind is built for patterns; it doesn't like boring repititions." Just because we have the freedom to choose, a.k.a. "free will," does not guarantee our choices is random.

    This experiment just shows that, when we aren't given enough time for the "consciousness circuitry" within our minds to make its choice, other circuitry in our minds take over and make for some interesting results. Maybe, instead of debating whether or not free will exists, we should instead attempt to analyze what cranial pathways are taking over. I'd be very interested to know what portions of the mind take over when it's forced to make split-second decisions, then measure whether or not these decisions are more accurate, or in what ways, compared to the "I've had time to think about it, and I've concluded..." choices.

It would be akin to asking them to pick a number between 1 and 10 and then seeing how "good" they are - there's no way to actually guess it and nobody is going to actually be better than someone else.
