The Copernican Method Against the Copernican Principle: Anthropic Typicality over Partial Information States
Abstract
How can a predeclared record constrain observer abundance under an observer-conditioned sampling model? We derive a finite testing result from a single principle, the Accordance Principle, which governs typicality over partial, observer-indexed information states rather than complete histories and follows from two mediocrity commitments by one application of Bayes’ theorem. Given a predeclared record of m rare-side realizations at prior below one half, suitable probability bounds, and a stated statistical antecedent imported as a premise, the test rejects an abundance hypothesis P(H) ≥ ε at a level that falls with m and can approach zero. The result is a statistical rejection rather than a contradiction: typicality, assessment under the cosmic weighting over possible histories, and the abundance hypothesis can all hold while the test rejects, with probability at most its level. Applied to the astrobiological Copernican principle, the test addresses an explicit quantitative hypothesis under auxiliary assumptions, and its Rare Earth conclusion holds under an abundance-and-independence condition whose empirical inputs the paper’s status table does not yet certify. On the diagnosis proposed, the received reference-class problem is an artifact of reasoning over completed histories, with the choice of sampling measure and granularity remaining in its place.
