Proofgoal
The elusive, often vaguely defined, piece of evidence that an arguer claims would settle the issue for them. It is presented as a reasonable target but is usually defined with such specificity or grandeur that it is practically unattainable, functioning more as a conversation-ender than a genuine objective.
Example: In a climate debate, someone says, “My proofgoal is a single, undeniable piece of evidence that 100% conclusively proves human activity is the sole cause of all warming, with zero margin for error or natural variation.” This “proofgoal” is a mythical, perfect piece of evidence whose impossibility is used to justify ongoing skepticism.
