In a certain mythical community, politicians never tell the truth, and non-politicians always tell the truth. A stranger meets three natives and asks the first of them, "Are you a politician?" The first native answers the question. The second native then reports that the first native denied being a politician. The third native says that the first native is a politician. How many of these three natives are politicians? Explain your answer.
ANSWER: If the first native is a politician, then he lies and denies being a politician. If the first native is not a politician, then he tells the truth and denies being a politician. In either case then, the first native denies being a politician.
Since the second native reports that the first native denied being a politician, he tells the truth, and is therefore a non-politician.
The third native asserts the first native is a politician. If the first native is a politician, then the third native speaks the truth, and is therefore a non-politician. If the first native is a non-politician, then the third native speaks lies and is, therefore, a politician. Hence, only one of the first and third natives is a politician, and since the second is a non-politician, there is only one politician among the natives.
