New Scientist usually puts out great stuff, but this video? Eh. I was tossed up over whether to post it or not. Check it out for yourself, maybe i’m missing something. 🙂

Every now and then an idea comes along that upends how we see ourselves and our place in the cosmos. The rumblings of the next revolutions in our thinking may already have started. Here are four potential “what ifs” with the potential to change us forever.
I have been a fan of Dr. Susan Blackmore ever since i read her book In Search of the Light: The Adventures of a Parapsychologist.
One of my favorite topics she writes and talks about is her theory that we don’t have free will. I am fascinated by such a counterintuitive idea. Maybe you will be too.
This video is about an hour long, i haven’t finished watching it yet, but i’m sure i will enjoy it if it’s like all her other discussions.
We all like magic and more importantly we all like to think we can work out magic tricks if we really want to. But as it turns out, even a simple card trick utilizes neuro-scientific principles to trick our brain in ways that we usually can’t consciously control. So what exactly is wrong with our brain? Well nothing really, but years of evolution has left it with traits that leave it wide open to be duped by magic. For example . . .
10 • Focus
Multi tasking is a myth, the human brain simply wasn’t designed to focus on two things at once and magicians take full advantage. Our attention is pulled to one thing in particular due to the ‘moving-spotlight‘ theory. In short, the theory says that our attention is like a spotlight, highlighting one thing while leaving what surrounds it in the dark. When an item or action is within the spotlight the parts of the brain involved in processing it work more efficiently, but anything beyond the spotlight is barely processed at all, at least not by our conscious mind. This allows magicians to pull a sleight of hand right under our noses, as long as something else is drawing our spotlight what happens beyond it, to our brain isn’t happening at all.
9 • Made Up Memories
The ‘misinformation effect’ occurs when information we are given after an event alters our memory of it. For example, a magician asks you to choose a card from the left side of the deck and return it without telling him. Before the razzle-dazzle where he guesses your card he may say something like ‘Now you chose any card you wanted, correct?’ And in the heat of the moment you will say you did. The truth is you were only given the option of the left side of the deck, but the ambiguous comments from the magician alters how you remember the trick, leaving you with a false memory making the trick seem perhaps more incredible than it was.
8 • Predicted Wrong Future
When you see a ball get thrown in the air, it comes back down. You’ve a seen it a million times. You know that what comes up must come down and so does your brain. In fact because of something called the ‘Memory-prediction framework’ our brain sometimes remembers certain actions so well, it stops paying close attention because it predicts how they will end. When a ball gets thrown in the air our brain instantaneously recalls memories of similar events and produces an idea of what’s going to happen next, but sometimes it’s wrong. When a magician puts a ball in a cup only to have it disappear when the cup is lifted, we are shocked because what our brain predicted didn’t come true. Our brains often feed us a prediction and convinces us we saw it happen, which leaves us even more shocked when the predicted action didn’t happen at all.
7 • Free Will
When we ‘pick a card, any card’ we are very rarely picking at random, no matter what it seems. It is usually the magician choosing for us, only without our knowledge. In many card tricks the card we apparently choose is ‘forced’ meaning the magician did something, mental or physical, to make us choose exactly what they wanted us to. But our brain will often over look or deny this as an option, in favor of free choice. Our brain simply does not want to believe it was forced and will often omit facts that may indicate that it was, instead jumping fully into the false idea that all choices were all our own.
6 • Filling in The Blanks
The ‘woman sawed in half trick’ is old enough that most people know the secret. The head we see in one end of the box doesn’t belong to the legs we see at the other. But our brain insists and assumes it does, why? Because our brain is a sucker for continuity. When it sees a head in rough alignment with a set of legs it uses past experience to fill in the blank and tell us that obviously a torso exists between those two body parts. In many magic tricks an object is partially covered, and our brain uses what it CAN see to continue the image and fill in the blank, of course that is exactly what the magician wants.

Humans have debated the issue of free will for millennia. But over the past several years, while the philosophers continue to argue about the metaphysical underpinnings of human choice, an increasing number of neuroscientists have started to tackle the issue head on — quite literally. And some of them believe that their experiments reveal that our subjective experience of freedom may be nothing more than an illusion. Here’s why you probably don’t have free will.
Indeed, historically speaking, philosophers have had plenty to say on the matter. Their ruminations have given rise to such considerations as cosmological determinism (the notion that everything proceeds over the course of time in a predictable way, making free will impossible), indeterminism (the idea that the universe and our actions within it are random, also making free will impossible), and cosmological libertarianism/compatibilism (the suggestion that free will is logically compatible with deterministic views of the universe).
Now, while these lines of inquiry are clearly important, one cannot help but feel that they’re also terribly unhelpful and inadequate. What the debate needs is some actual science — something a bit more…testable.
And indeed, this is starting to happen. As the early results of scientific brain experiments are showing, our minds appear to be making decisions before we’re actually aware of them — and at times by a significant degree. It’s a disturbing observation that has led some neuroscientists to conclude that we’re less in control of our choices than we think — at least as far as some basic movements and tasks are concerned.
At the same time, however, not everyone is convinced. It may be a while before we can truly prove that free will is an illusion.
