Epidemiology and the scientific method.

This article refutes the claim that the field of epidemiology and community health would benefit from the application of the scientific method. It is argued that the methods of physics are not appropriate for other disciplines. When applied to the social sciences, positivism is a conservatizing force, causing theory to become based on a mere description of social phenomenon. Since it cannot lead to a deep understanding of social phenomena, positivism is incapable of revealing ways in which society could be radically changed. Moreover, such theory is far from neutral. Rather, it is formed and influenced by the forms of life experienced and practiced in the society. This is illustrated by an analysis of the origin of modern physics at the time when society was changing from a feudal to capitalist form of organization. It is concluded that advances will be made in epidemiology and community health when this field breaks from its focus on the individual and incorporates class into its analysis. However, given the interconnection between social structure and social theory, resistance to such a radical change can be expected.
