Newcomb's Paradox

This gimmick allows you to perform a working version of the famous Newcomb’s Paradox where you the magician are able to perfectly predict the spectator’s decision before they even make it for themselves. Newcomb’s Paradox is a philosophical thought experiment that raises questions about causality, determinism and free will. There are two boxes. Box A is open and clearly contains $1. Box B is shut and has already been set by a perfect predictor.  If the predictor has predicted that the spectator will greedily choose both boxes, then box B contains nothing. If the predictor has predicted that the spectator will choose only box B, then box B contains $2.  This thought experiment is famous because philosophers still cannot agree on which is the correct strategy in this simple game. Should the spectator choose one box or two?   The trick may be repeated any number of times, and sure enough the magician, or their smart phone ai, is always able to predict the spectators choice, and remove the $2 coin any time before a greedy two box choice is made. This gimmick takes the story even further. The magician is able to make the coins disappear completely and finally reveal a surprise item such as a bank note to magically appear from within the box.
