- Explanation of the marking system
Any marking system has to be invisible to our spectators but identifiable at first glance by us - the all-knowing mystery performers. Every marking system has to operate between these two poles.
Our marking system is the one that works for us.
In creating our marking system we utilized a special feature of the human sense of sight responsible for the neuronal information processing.
In short you always see what you expect to see at a special place. Our brains tend to replenish visual perceptions to mental images which match our experiences. This is the basis of plenty of optical illusions – and now we will benefit from this mechanism.
You will surely appreciate that an unsuspecting layperson doesn’t notice the markings simply because he sees the backs of our cards as he expects them to be.
Yourself on the other hand, once you know the system, will never be able to miss or disregard the markings; they will appear automatically in front of your eyes!
