In this video Julie Galef, host of the Rationally Speaking podcast (about philosophy, rationality, science) presents one of my favorite paradoxes - Newcomb's Problem (and the related and "Parfit's Hitchhiker" dilemma).
Before Carla and I started the bOING bOING zine, I published another zine in the mid-1980s called Toilet Devil (Koko the talking ape calls people and her pet kitties "dirty toilet devils" when she is mad at them).

A highly superior being from another part of the galaxy presents you with two boxes, one open and one closed. In the open box there is a thousand-dollar bill. In the closed box there is either one million dollars or there is nothing. You are to choose between taking both boxes or taking the closed box only. But there's a catch.
The being claims that he is able to predict what any human being will decide to do. If he predicted you would take only the closed box, then he placed a million dollars in it. But if he predicted you would take both boxes, he left the closed box empty. Furthermore, he has run this experiment with 999 people before, and has been right every time.
What do you do?
On the one hand, the evidence is fairly obvious that if you choose to take only the closed box you will get one million dollars, whereas if you take both boxes you get only a measly thousand.
