Abstract

This paper defends two principles of methodological conservatism on the grounds that they help to promote an effective social structure for a knowledge‐seeking community. Conservatism has some prima facie justification because it provides for an effective division of cognitive labor, it promotes the effective use of scientific resources, and it provides for a certain amount of stability. However, the principles I defend in this paper should not be treated as absolute or unconditional criteria of theory‐choice, since they can be overridden by other rules or maxims. Since the decision to override a principle of conservatism depends on various contextual factors, the appropriateness of conservatism can vary from context to context.
