According to Thomas Kuhn, theory-choice is guided by a set of shared values. However, scientists differ concerning the way these values are interpreted. They also differ about the respective weight given to those values. Kuhn’s conclusion is, then, that theory-choice is an inherently subjective decision. By taking into account recent methodological practice, this essay argues that subjectivism can be minimized. Model-selection and Bayesian inference are subsequently considered. Criteria for comparing models show that values are not independently pursued while Bayesian inferential apparatus can be applied so that subjective factors are partially neutralized.
