Reasoning Logic Check

CORE DEFINITION

The practice checks whether reasoning obeys logical rules, using explicit criteria as the standard of judgment. The usual tests are validity, whether the conclusion follows from the premises; consistency, whether the claims can hold together; relevance, whether the evidence bears on the claim; and sufficiency, whether enough support is present. The core claim is that converting an impression that something is wrong into a named violation makes the defect fixable and the argument assessable by others. The qualification is that formal correctness does not secure substantive truth, since a valid argument from false premises still fails.
