Two people reach an impasse over a simple factual question. One has checked the records, traced the sequence, and arrived at a clear conclusion. The other insists on an alternative that contradicts every verified step. Only one can occupy the ground marked correct.
The logic of exclusion
Correctness is not a shared resource. A statement either aligns with the evidence or it does not. Once alignment is established, any contrary claim is displaced. The speaker who can demonstrate that alignment therefore occupies the only tenable position. Appeals to mutual respect or plural perspectives change nothing about that displacement.
Consider the basic structure. If set A is accurate, then any set B that negates A must be inaccurate. The negation cannot be rescued by politeness, volume or institutional weight. Those factors may prolong the disagreement, yet they leave the underlying contradiction untouched.
Correctness does not bargain for company.
Evidence decides, not consensus
Concrete checks settle the matter. A date recorded in an official ledger, a measurement taken under controlled conditions, or a chain of custody that can be examined all function as fixed points. When those points support one narrative and undermine another, the first narrative stands alone. Attempts to treat both narratives as equally viable require ignoring or misrepresenting the same fixed points.
Even in fields where provisional findings are common, the moment a claim is shown to match the best available data, contradictory claims lose standing. Subsequent revisions may occur, but they do so on the basis of new data that again privileges one account over others. The pattern remains the same: one description fits; the rest do not.
Rebuttals that defeat themselves
Objections often arrive in two forms. The first claims both sides might be partly right. This dissolves once the contradiction is examined; partial alignment on peripheral details does not repair central incompatibility. The second insists that certainty is impossible. That insistence itself asserts a definite view about knowledge and is therefore subject to the same test: if it cannot be sustained by evidence, it falls.
Both objections ultimately seek to restore symmetry where symmetry has already been broken by the evidence. They do not create a second correct position; they merely delay acceptance of the single one that exists.
The rule is therefore straightforward. The person whose account matches the facts is correct. Anyone whose account negates those facts is not. No amount of subsequent protest alters that distribution.
