 Two opposite arguments for what the player should decide can be given. Assuming the player has a free will it seems rational to say that the fortune teller cannot in principle predict what the player is going to do. When the player makes her choice, it is already determinate whether box \(B\) contains 1,000,000 dollars or nothing. Therefore her choice cannot be affected by the fortune teller’s prediction, and she would be better off by selecting both boxes, hoping that there already is 1,000,000 dollars in box \(B\). The other argument maintains that based on previous experience—which tells us that the fortune teller has always been correct about her predictions—it would be most rational of the player to take only \(B\). From here philosophers have disagreed about the strength of the argument. One could insist that fortune teller can predict the player’s choice only based on relevant knowledge of that person’s past or present behavior or state of mind (compatibilism). Alternatively one could argue that the fortune teller could have such a perfect knowledge only from information about the player’s choice in the future.
