 By itself, this 2D framework offers no guarantee that the hypothetical judgments recorded by an A-intension are produced by a stable reference-fixing criterion. Nor does it guarantee that the very same A-intension will be generated for all competent speakers in your linguistic community. However, according to Jackson, we have solid empirical reasons to think these conditions are satisfied in the case of names and natural kind terms. First, the widespread acceptance of the externalist thought experiments demonstrates that we do in fact share similar reference-fixing criteria for terms like ‘water’ and ‘Gödel’ (Jackson 1998a, 38–39). Second, the empiricist model of meaning provides the best psychological explanation of how such linguistic coordination is achieved (Jackson  1998b).[13]
