Nearly Hanging

A prisoner is told, “If you tell a lie we will hang you; if you tell the truth we will shoot you.”

What can he say to save himself?

You will hang me. If they hang him, then the statement was true and they could only hang him for telling a lie. If they shoot him, then it makes the statement a lie and they were only to shoot him for telling the truth. An alternate solution is to say, “You will not shoot me,” leading to the same quandary for the killers.

Four of Us In Your Field

Four of us are in your field
But our differences keep us at yield

First, a one that is no fool
Though he resembles a gardener’s tool

Next, one difficult to split in two
And a girl once had one as big as her shoe

Then, to the mind, one’s a lovely bonder
And truancy makes it grow fonder

Last, a stem connecting dots of three
Knowing all this, what are we?

The four suits in a deck of standard playing cards

The Spade is a gardener’s tool.

The Diamond is the hardest gem to break. “Little Girl and Queen” is a Mother Goose rhyme, in which the Queen gave the girl a large diamond for picking the Queen some roses.

The Heart bonds with the mind to form love. Absence makes the heart grow fonder.

The Club, or Clover, is three dots connected around a stem.

Four Cards

Four cards are placed in front of you on the table, each with a number on one side and a color on the other. The visible cards show 3, 8, red and brown. Which cards should you turn over in order to test the truth of the statement that if a card shows an even number on one face, then its opposite face is red?

four-cards

You’d need to turn over only the 8 and brown card. Only a card with an even number on one face and which is not red on the other face can invalidate the stated rule. If you turn over the 3 card and it’s not red, it doesn’t invalidate the rule, nor does turning over the red card and finding it has the label 3.

This test was devised by Peter Cathcart Wason and is known as the Wason selection task. Less than 10% of test subjects got it correct in two separate studies.
