 Although it is not always explicit in FSCs, the counterfactual intervener appears to reply on some prior sign of what the agent is about to do (Blumenfeld 1971). Black’s device, for example, is sensitive to Jones’ inclination: if it detects an inclination (call it “Pro-D”) to choose the Democrat, Black will intervene; if it detects an inclination (“Pro-R”) to choose the Republican, Black will remain idle. As matters turn out, Pro-R appears, Black does nothing, and Jones votes for the Republican on his own. The dilemma is this: either Pro-R determines (or is associated with something that determines—a qualification to be left out for simplicity) that Jones will vote for the Republican, or it doesn’t. Either way, the FSC fails as a counterexample to PAP.
