    Deductive Thinking: the 3 geniuses and the hats
    Three geniuses stand in a file (one behind the other). Each can see only to the front, so the rear person can see the middle and the front, the middle person can see the front, and the genius in the front cannot see anyone.
    You have five hats. Two are white, and three are red. You blindfold the three geniuses, who are utterly truthful, and put a hat – at random – on the head of each. Then you hide the other two hats and remove the blindfolds.
    You then ask each genius to name the color of his hat (which he cannot see).
    The rear one says "I don't know." The middle on says, "I don't know." Then the front one says, "I know."
    WHAT COLOR IS THE FRONT GENIUS' HAT??
