Imagine knowing something that would normally be impossible to know. For example you might want to reveal someone’s surname, even though you never met them before. You might want to know what their best friend’s hamster is called. Whatever it is, this Prediction effect will allow you to do so. In this case we will reveal the PIN number of a person’s bank account.
You ask to borrow a pen and pencil from the subject. You confirm with them that they have a PIN number for their bank and that there is no way you could possibly know it. You write down a 4 digit number and return them the pencil. You ask them your pin number and it matches what you have written on the paper.
