Just came across this thread...
First, is anyone using the "A Truth To Tell" routine from TOTM? I am wondering if a spectator ever messes up (either on purpose or by accident). Or does anyone ever guess the method?
I'm just fascinated by the HUGE potential of this routine and have been working on my scripting and routine. I've been occasionally using Truth by Paul Richards as a demonstration of human lie detection. Paul's Truth is really clever and fun to perform but Barrie's routine is SO frickin organic. And why would anyone buy one of those Minimax gizmos when you can do real, impromptu lie detection. But I digress...
Here is my untested routine. It is pretty much Barrie's routine with my touches and a different reveal method that I think might have a better impact. I'm thinking this would be good for walk around at a restaurant or weddings...at a table of at least 3 people...with napkins available.
The inspiration for this routine comes from my mother. My mom was a human lie detector. Anytime something mischievious happened she would line my brother and I up and say "Look me in the eye....did you spray paint the cat?" Moms are able to tell when their kids lie from the their eye movements and facial expressions. I need the help of 3 people from this table. I'm not going to ask you to lie, that would be unethical. Someone is going to do the lying for you. I want you to imagine a little person in this hand. This person is a liar. He can only lie. If I give him a piece of candy and ask "Do you have a piece of candy?" he will say no. In this hand I have a little person that can only tell the truth.
Reach out and grab two little people like this...I pretend to grab a little person in each hand.
Now in your mind, select the hand the has the liar. During this demonstration, don't forget which hand has the liar. And I will never ask you which hand has the liar.
Excellent, relax your hands for a minute. Tear off a small piece of your napkin and roll it into a ball. As I turn my back place the little ball into one closed hand or the other. Hold both hands in a closed fist above the table. Good. Now recall which hand has the liar.
Let's review. You have not told me which hand holds the liar. Nor do I know which little person has the napkin. Could be the liar. Or it could be the truth teller.
I'm not going to ask for a spokesman like Barrie does. After some pretend concentration, I'm just going to touch one hand of the closest spectator.
I am going to ask the person in the hand I just touched a question. Remember if I am addressing the liar, he must lie and the truth teller must tell the truth. To the hand I just touched "does the liar have the napkin? " After much mental anguish, I am going to have the spectator place the closed fist that is EMPTY on their lap, keeping the other closed fist above the table. If you don't know which hand is empty then buy this great book for the secret! Repeat for each spectator with plenty of acting and suspense.
At this point, all three specs have one hand above the table.
To recap, no one has told me which hand holds the liar. The hand you hold above the table could be the liar or the truth teller. There is no way I could possibly know as you've never told me or anyone else. And you've never told me which hand holds the ball. I have no way of knowing where the napkin balls are. On the count of 3 you will turn your hand palm up and open it...1....2......3Each open hand should hold a napkin ball.
I like this idea. You need repetition in order to make the lie detector believable as more than luck. But the repetition could get boring. With the delayed reveal of all three, it seem much more impossible and dramatic.
I would appreciate any feedback before I take this out into the real world.
