 This thought experiment involves a player playing a game against a fortune teller. In this game there are two boxes of which the player may select one or both. One of the two boxes is transparent, let’s call it \(A\), the other is opaque, call it \(B\). Before the player makes her choice the fortune teller, based on her prediction of the player’s choice, puts a certain amount of money in one or both boxes. When the player makes her choice, the following information is available to her: 1) Up to now the fortune teller has been able to predict the future with absolute certainty and has foreseen what other players have chosen. Moreover: 2) sometimes the fortune teller puts 1,000,000 dollars in box \(B\), but only if the player selects box \(B\) and does not take both boxes, whereas she puts 1,000 dollars in box \(A\), regardless of whether the player chooses box \(A\) or both boxes. So when the player has to choose between the two boxes, it is already determined whether box \(B\) contains 1,000,000 or nothing. If the fortune teller is correct in her prediction, the player will get 1,000,000 dollars, only if she selects box \(B\); however, if the player wants to earn 1,001,000 dollars and selects both boxes, she will miss most of the fortune and only receive 1,000 dollars, which she can already see in box \(A\).
