Moving the Proofgoal Example: After being shown multiple eyewitnesses and forensic reports for an event, a skeptic says, “Okay, but my ultimate proofgoal was always a continuous, unedited video from a neutral third party covering every single second. Since that doesn’t exist, I remain unconvinced.” They’ve retroactively moved the finish line to a different planet.
