 The source of the misunderstanding concerning incomparability appears to be Feyerabend’s onetime suggestion that “incommensurable theories may not possess any comparable consequences” (1962, 94). However, here Feyerabend was arguing that although the same experimental set-up might produce a numerical result that can be used to confirm both of two incommensurable theories (e.g. measuring the time of a freefalling stone to test predictions by both Newtonian mechanics and Relativity theory), in order to use the result to confirm a theory, it must be interpreted by that theory. Given that the two incommensurable theories will use qualitatively incompatible concepts to interpret quantitatively identical results, they will interpret the same quantitative sentences as different qualitative statements. Feyerabend concluded directly thereafter: “Hence, there may not exist any possibility of finding a characterization of the observations which are supposed to confirm two incommensurable theories” (1962, 94, italics inserted). This does rule out the possibility of using a neutral observation language to compare the empirical consequences of two incommensurable theories. Yet Feyerabend did not conclude that this inhibits their comparison, but rather that there is no need for a neutral observation language in order to compare them. Feyerabend also mentions other possibilities of comparing incommensurable theories (Feyerabend 1965b, 217; 1970, 228; 1975, 284; 1978, 68; 1981a, 16). Some of these involve making subjective judgments about how to weigh different values that may pull in different directions (methodological incommensurability).
