Break the class into groups of three (this exercise can be adjusted for groups of four). Have each student write down four statements about themselves—three should be truths, and one should be a lie. The lie should not be obvious; each student’s objective is to sell the lie as truth along with the actual truth. Going around the circle, each student states the truths and the lie. The group may ask a maximum of two follow-up questions for each statement. Then the group votes on each of the statements: truth or lie? The student can finally reveal the lie after everyone has voted. After everyone in the circle has taken a turn, the group answers the following questions:
6-8. How many of the lies were detected? Were they easy or difficult to detect?
6-9. What made you think a statement was a lie: was it the probability of the statement itself, or the
delivery by the student?
6-10. Do you think it is possible to be a good liar? What factors would a good liar have to control in order
to pass off a lie as truth?
