Graphology

Handwriting is something which may or may not identify one person from another. It's a moot question and therefore leaves the path open for an astute performer to make the most of things. Effect: The performer explains that he is a student of graphology and will give a test of his ability to read people's characteristics from their handwriting. He passes out ten to twenty business cards and asks those receiving them to write a certain sentence on the blank sides of the cards, while he is out of the room.

These cards are collected by an obliging spectator in a hat and shaken up. When the performer returns to the room, he picks a card at random from the hat, studies it for a moment... looks over the faces of the guests, and then hands it to the person who had written it. He proceeds to do the same thing with the rest of the cards, to the amazement of those present, not making a single mistake.
