Moving-the-goalposts is the argumentative fallacy in which the standard of proof required to accept a claim is changed mid-debate after the original standard has been met or challenged. PARAMETERS: (1) an initial evidentiary threshold set or implied by the claimant; (2) an attempt to meet that threshold; (3) the claimant rejects the attempt as insufficient; (4) the claimant raises the threshold to a higher standard that was not previously required. PERSISTENCE: the pattern persists through instruction in debate, documentation in rhetorical handbooks, naming in logical fallacy catalogs, and repetition in public discourse where participants invoke the term to call out the tactic.

    Definition carves per Law 4: parameters are explicit (initial evident standard, mid-debate change, challenge to original). The persistence mechanism is language/teaching — argumentative tactics persist through social learning and rhetorical training.

    Definition meets Law 4: states parameters (changing standards, mid-debate timing, evasion of refutation) and persistence mechanism (argumentative practice, rhetorical education). Law 6 trailer present. The definition carves specifically — it does not fit many things (other fallacies like strawman, ad hominem, red herring don't share the mid-debate standard-shifting feature) and fits this one precisely.

    Definition correctly identifies moving-the-goalposts as an argumentative fallacy. Carves the concept with clear parameters — initial standard, meeting/challenging it, then changing. Ends with proper trailer.

    Definition correctly carves moving-the-goalposts with parameters (initial standard, change after meeting/challenge, shifted burden). Law 4 satisfied.
