Game Theory Joke


A Scorpion begged a Frog to carry him across the river because he could not swim. The Frog hesitated for fearing being stung by the Scorpion. The Scorpion said: "Don't worry, you know I won't sting you since we will both drown if I do that". So the Frog carried Scorpion across the river. But in the middle of the river, it happened--the Frog got a sting. Before he died, the Frog asked Scorpion in disbelief: "I don't understand why you did this!?" "Because I am not a game theorist and you are", replied the Scorpion.

I think our scorpion is a game theorist. It was his dominate strategy to sting all along. He is a noncooperating game player.
