It is widely supposed that the scientists in any field use identical standards for evaluating theories. Without such unity of standards, consensus about scientific theories is supposedly unintelligible. However, the hypothesis of uniform standards can explain neither scientific disagreement nor scientific innovation. This paper seeks to show how the presumption of divergent standards (when linked to a hypothesis of dominance) can explain agreement, disagreement and innovation. By way of illustrating how a rational community with divergent standards can encourage innovation and eventually reach consensus, recent developments in geophysics are discussed at some length

For positivists and post-positivists alike, methodology had a decidedly suspect status. Positivists saw methodological rules as stipulative conventions, void of any empirical content. Post-positivists (especially naturalistic ones) see such rules as mere descriptions of how research is conducted, carrying no normative force. It is argued here that methodological rules are fundamentally empirical claims, but ones which have significant normative bite. Methodology is thus divorced both from foundationalism and conventionalism.
