Is there a term for this type of logical fallacy?
One person asserts that theory A would predict outcome X. We have observed, however, that outcome Y occurred and not outcome X. The first person asserts that this is evidence that theory A made a bad prediction. A second person asserts that theory A would not predict outcome X, and therefore outcome Y is not problematic for our faith in theory A.
Is there a type of fallacy where a person dismisses the possible ex ante prediction of A-->X based on ex post knowledge, fitting their interpretation of the theory and its predictions to observed outcomes.
