Carnap's criterion of cognitive significance

Carnap's criterion of cognitive significance is a way to determine whether a statement or theory is meaningful and informative. It suggests that for a statement to be cognitively significant, it must have the potential to be confirmed or falsified through observation or experience. In other words, meaningful statements should connect to empirical evidence, allowing us to test them and distinguish between correct and incorrect ideas. If a statement cannot be tested or linked to observable facts, it is considered cognitively meaningless, as it offers no way to verify or refute it through experience.
