Early sociologist Max Weber prefers a form of structuralism over a base and superstructure model of society in which he proposes that the base and superstructure are reciprocal in causality—neither economic rationality nor normative ideas rule the domain of society. In summarizing results from his East Elbia research, he notes that contrary to what he considers the base and superstructure model "we have become used to," he observed a reciprocal relationship between the two.[6]
