The man sitting across the table from you is known for trickery. He is a
stage magician. You know he employs trickery, so he tells you he is
going to do a card trick in which he can't possibly manipulate the
cards. In this trick, you will do all of the card handling. He won't
touch the cards at all.
He instructs you to cut the deck into
four piles. You do so. He then tells you that you are going to randomize
the order of the cards by shuffling them around and moving cards from
one pile to another. Pointing to a pile of cards, he instructs you to
take the top three cards and place them at the bottom of that pile.
Then, take the next three cards and place them, one each, on top of the
three piles remaining on the table. You repeat the procedure with all
four piles of cards. The cards should now be very well mixed.
The
man then begins his patter in earnest. He asks you to confirm the fact
that he has not touched the cards. You agree. In no way could he have
manipulated how you would cut the cards or handle them. Again, you
agree. With a smile, he asks you to turn over the top card from each
pile. You are amazed. The four aces sit at the top of each of the four
piles of cards. For a moment, your mind might actually entertain the
possibility that real magic has been performed, though you "know" you've
been duped.
The fact is, this trick can be taught in a couple of minutes to
any child capable of understanding the instructions. It requires no fine
motor skills for clever card handling since the performer does not even
handle the deck. The only thing required is setting up the deck before
the trick is performed and being able to do a little sales patter in
which you get the audience to agree to a statement that is blatantly
false.
Take a moment and see if you can identify the lie that
makes the trick believable. Everything the magician says is true with
one exception. The trick is based completely on a facet of human
psychology that most people--stage magicians, salesmen and politicians
aside--don't understand. When a person is given a number of facts that
are demonstrably true, they will tend to group all statements in that
group together, agreeing to everything said, including an embedded lie....<<<Read More>>>...
