Cultural values may constructively have impact on scientific practices, and lead to legitimate culture-based variations in approaches to them. It follows that traditional or indigenous knowledge need not stand opposed to scientific knowledge, and only investigation on a case-by-case basis can establish whether or not the cognitive credentials of particular traditional knowledge claims are adequate or deficient. Building on an analysis of how different methodological strategies may both compete and complement one another, I argue that what is defensible about Thomas Kuhn's notion of incommensurability, and the possibility of the sound scientific status of traditional knowledge, have the same source.
