In **Newcomb's problem**, a superintelligence called Omega shows you two boxes, A and B, and offers you the choice of taking only box A, or both boxes A and B. Omega has put $1,000 in box B. If Omega thinks you will take box A only, he has put $1,000,000 in it. Otherwise he has left it empty. Omega has never been wrong in his predictions about whether someone will take both boxes or not.

Terms used in relation to this paradox:

**Omega**, the superintelligence who decides whether to put the million in box A.**one-box**: to take only box A**two-box**: to take both boxes
