This paper by Paul F. Lazarsfeld (1934) offers a methodological paradigm for the emergent field of sociography, defined as comprehensive empirical surveys of social phenomena without rigid object boundaries. Lazarsfeld identifies and elaborates five “heuristic axes”—subjective versus objective data, individual cases versus statistical patterns, present versus historical data, natural versus experimental data, and elementary versus complex units—which together structure robust sociographical data collection. Drawing from exemplary studies such as the Marienthal investigation, the author demonstrates how integrating these axes uncovers multifaceted insights into social behavior and attitudes. The paper further introduces the concept of “matrix formulas” to synthesize and communicate research findings, stressing their practical, heuristic, and communicative value while acknowledging their inherent arbitrariness and dependence on available data. Lazarsfeld situates sociography at the intersection of psychology, sociology, and the humanities, and provides critical reflections on its methodological limitations, especially regarding representational models versus explanatory causal frameworks. The work remains a foundational text for researchers seeking to understand social objects in all their empirical and interpretive complexity.
