explores the thought of human lie detection.
With shows like "Lie to me" and "The Mentalist" in vogue at the moment, realistic demonstrations of similar abilities are also becoming ever more in demand. Here we have a direct, to the point three phase lie detection effect. You will appear to genuinely have this ability if you so wish.
The performer removes two cards from the deck; upon one’s face he writes “Truth” and the other “Lie.” These cards are to be used in an experiment of psychological lie detection.
The performer holds the cards face-down. The spectators are invited to say a statement about themselves; this can be either truth or a lie.
For example: “I live at house number 42.” Or perhaps, “I have a cat.”
Once the statement is said, the performer selects one of the two cards and the spectator reveals if it was truth or lie. The performer is correct. This is a skill that everyone possesses; it’s just a case of tapping in.
A second spectator is offered the chance to guess if the first spectator is lying or telling the truth. A statement is said and it is shown that the second spectator too was correct in their thoughts! Up to now, this has been just a 50/50 chance of success; the performer offers to turn it up a notch.
The rest of the playing cards are taken out and the spectator draws a truly random card from the middle to remember. Four other random cards are dealt out also and the five are well mixed by the spectator. From here the spectator lays out the five cards face up in a row.
They are asked to touch each card, one by one, saying: “This is my card” in each instance. It’s the performer’s job to guess on which occasion is the truth being told. The performer of course names the correct card, proving his lie detection skills to be second to none!
[Note that part of the methodology is a nice version of equivoque. If you have never worked with equivoque this might be a good place to start.]
