The Invasion of the ROBOTS!!
Friday, January 18th, 2008It’s True!
Watch out!! They’re out there!! They look like people; they eat like people; they listen to music; they seem to feel emotion. But don’t let that fool you!
Some scientists, devotees and writers today talk about the “illusion” of free will. The choices that we seem to experience thousands of times a day, are really out of our hands. Perception of what we’re doing comes later. Some how observations that researchers make a couple dozen times a day, are different from our propensity to fool ourselves.
So we have a frequent and commonly agreed perception which as far as I know still continues to work, despite not having been confirmed by Science. Taking both facts and relating them we have ample evidence of the brain fooling itself. Yet a researcher is often spoken of as if they were a disembodied observer, somehow not barraged my the brain’s evident ability to confuse itself about what came first.
Sometimes, I can’t believe they are talking about the same brains that they are trying to convince us have fooled us all along.
The “proof” of this is, as the New York Times puts it (here) “A bevy of experiments in recent years suggest that the conscious mind is like a monkey riding a tiger of subconscious decisions and actions in progress, frantically making up stories about being in control.” Like other agents of this idea, they cite the Libet studies of the 70s and 80s.
Dr. Libet found that brain signals associated with these actions occurred half a second before the subject was conscious of deciding to make them.
The order of brain activities seemed to be perception of motion, and then decision, rather than the other way around. http://www.nytimes.com/2007/01/02/science/02free.html?pagewanted=2
Where was Libet standing? What was his body doing at the time. Was he looking at the monitor? Did his body just decide to point his head toward the monitor and he said, “Hey I want to look at the monitor”? Look how that worked out! He ended up seeing what it was his research to see!
Here’s another representation from Science Week:
Libet’s team measured [how?]two objective parameters: the electrical activity over the motor areas of the brain, and the electrical activity of the muscles involved in the wrist movement.
But Libet also found [any physical actions?] a surprising temporal relation between subjective experience and individual neural events. The actual neural preparation to move (RP) preceded conscious awareness of the intention to move (W) by 300 to 500 milliseconds. Put simply, the brain prepared a movement before a subject consciously decided to move.
You gotta’ wonder if these scientists touch the floor as they are flitting about out of their bodies like this. They just “find”, “measure”, “correlate”, and “conclude”.
It Looks Bad for Our Heroes…
Sometimes, though, if you take a second look, you can spot the absurdity before your eyes. Take a look at the framework: (Again, from Science Week.)
In 1983, Benjamin Libet and his colleagues at the University of California San Francisco [did some stuff]. In this study, participants watched a small clock hand that completed one full revolution in 2.56 seconds. While fixated on the clock, a participant voluntarily flexed his wrist at a time of his choosing. After the movement, the clock hand continued to rotate for a random time and then stopped. Then, a participant reported the position of the clock hand at the time when she first became aware of the will to move.
Now such a things as “voluntarily flexed” and “at the time of his choosing” can’t happen, if it’s just the wrist moving and him deciding that he wanted to move it later. So it’s odd that Libet (provided he was rational) conceived of this experiment. Because the experiment seems to be a figment of his imagination as originally planned.
Why was the subject even conscious of his wrist moving? We can imagine a seen of a participant sitting serenely in a chair staring at the clock that his eyes and neck decided to look at, moving mostly just his wrist.
And, we can imagine the participants sitting serenely in the chair, because Tai-Bo or dancersize would kind of prove a distraction to judging when they decided to move that one part of their body.
So, what’s going on? Apparently his leg didn’t just fly up out of nowhere doing an imitation of John Cleese’s Silly Walks. But somehow his body just decides to do mostly only that which he was instructed to do by the researchers. Somehow his wrist, eyes, and neck decided to obey. As well as whatever firmware it is that tells time.
The experiment would be a joke if the doctors didn’t believe that they could plan (intend) to instruct a subject, that the subject could conceptualize it enough to code intentions to sit quietly and flex his wrist whenever it hit him.
So we have ample evidence of the instructions preceding the event. Instructions in the form of planning the test and explaining to the participant, and the participants odd feeling that he knew how to do all that and avoid his body doing something else.
If this is how the body acts, how could they in the preliminary trial even have trusted that the eyes would be in focus on the clock at the time the decision dialog box popped up? “Ding. You’ve got Movement.” We have to have a collision between the eyes just feeling like being in focus and the brain’s attempt to represent a time on the clock as the time.
He clearly intended to sit there (if he sat). He clearly intended to move his wrist and watch the clock. So what it seems to be the case is that the scientists can’t measure it yet.
So how much is this like “like a monkey riding a tiger of subconscious decisions and actions in progress, frantically making up stories about being in control”? The monkey might shake his head and convey that he’s going to sit still and only move the tiger’s wrist. But we don’t see him as being as effective at that as Libet (assuming he’s rational) saw in designing the experiment. I would suspect that no time-outs were planned for spontaneous Charlestons. The monkey on the other hand, will only say that he was intending the tiger to maul you, and he might decide later to move that wrist, but he’s mauling you now, and that’s kind of how things are going.
Real monkeys on the backs of real tigers (however unlikely that combination) have a connotation that we well recognize in providing the picture of futility. Real people planning, conducting, and complying with experiment plans also have an expected range of outcome. That provides the idea that Libet can even do this in the first place. (Provided he was rational in thinking that he could instruct anyone to move their body.)
In Clunk-clusion
It’s nothing like it at all. And both expectations (assuming Libet was rational) are likely to be highly successful. We can conclude a couple of things:
- Although scientist seldom touch the floor in their disembodied form, they can be very wrong about suggesting that they can pick up a pencil and plan how they are going test in experiments, and I’m guessing that because Science is not prey to brain illusions like I am that it is not a meat-forced error.
- Despite this unforced error, if Science don’t see it, it don’t happen.
- We should always live our lives by “best guess scenarios” which take lesser documented, alternate ideas off the table. Especially, if they don’t sound as “sciencey”.
- The same science that toasts your bread every morning, tells you that your legs have already figured out that your stomach wants toast.
- Wrists apparently listen real good. And even if we are riding around on a raging tiger, it’s wrists that we can expect to buckle down and complete the experiment.
- OR Science has a view that is limited by what has been proved before, but manages to turn that into a conviction that we can only accept what it can and has measured, no matter how much that conclusion ignores.
The Claim to Frame
It’s this last point that really makes it like Zeno’s most famous paradox. I resolve that one, not by playing along with the rules of the micro-game, but by contrasting it to its frame. If Hercules cannot win the race, having to pass through so many lines, then he can’t have gotten to the coliseum to stand at the start of the race just by walking at a slower pace. And nobody would be there to witness it (so there wouldn’t be a coliseum, where nobody goes) and nobody would know of anything called “a race” where movement that can’t happen happens.
Zeno may have had an academic point, but it is almost incontestable that that model was wrong for things known as races. Greeks will move and race, the tiger will eat you, the monkey won’t tell you stories, but people can be expected to execute a planned experiment doing something called “voluntary movement”. And that doesn’t change just because we can’t fit it all into a system or measure it.
This has been a presentation of my fingers.
