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.
