Theory and methodology Spaulding remains one of the early forerunners of the
New Archaeology. He was known for urging his fellow scholars to make use of quantitative statistics in archaeological research and maintaining his belief that anthropology was a rightful scientific discipline. As a result, his rigorous statistical methodologies and perseverance towards due scientific recognition remain pivotal elements in the historical evolution of archaeological research.
Quantitative archaeology Undoubtedly, Spaulding's greatest contribution to the field of archaeology was his insistence on using appropriate methods, namely
quantification. He asserted that quantitative applications promoted a more accurate methodology— a necessary component of scientific research. This is reflected in his hypotheses of archaeological data, where patterns can be inductively extracted from an attentive analysis of the data itself. The Ford-Spaulding Debate publicly emphasized this ideology and was instrumental in establishing an artifact classification method, acting as an impetus behind the
processual movement of the 1960s. His introduction of the
chi-squared test in evaluating the validity of typological patterns according to behavioral relations contributed to the "behavioral turn" seen in the
New Archaeology of quantitative application and behavioral reasoning. His theories greatly influenced
Lewis Binford (arguably the "founder" of the
New Archaeology) who found virtue in his statistical rigor and similarly believed in archaeology as a science, actively seeking to explain human experience rather than simply describe it. Binford, once a graduate student at the University of Michigan, credited Spaulding as his "most valuable teacher", "an intellectual rock of constructive thought and keen insight."
Archaeological dimensions In 1960, Spaulding explored his doctoral ponderings of the "dimensions of archaeology" in a critical— yet relatively forgotten— paper in which he defined a dimension as "an aspect or property of the subject matter which requires its own special measuring device." The basic analytical measurements within archaeology consisted of space, time, and form (and their interrelations), an essential concept still recognized in archaeological analysis today. Archaeologists study artifacts in the context of these three dimensions, and all archaeological inferences are affixed to any of these measurements. The relation of form and time represents a
diachronic approach while the relation of form and space represents a
synchronic approach; the alliance of all three constitutes a comprehensive archaeological unit and the foundation of
context. Although Spaulding's discussion focused largely on form and its conceivable statistical measurements, his understanding of the reality of all three dimensions can be considered a moment of clarity in the theory of archaeology.
National Science Foundation The discipline of anthropology has long been torn between the realms of science and the humanities. While those studying archaeology, physical anthropology, and cultural anthropology contend that their fields are entitled scientific inquiries, others believe anthropologists are restricted to the boundaries of the humanities. Spaulding was a staunch advocate of the former due to his passionate tenets concerning the place of quantification in archaeology. He carried this perspective with him to his director's chair at the
National Science Foundation, transforming the way the agency viewed the discipline of anthropology and instituting an invaluable resource. Millions of dollars became available to anthropologists through the NSF as the agency came to recognize the significance of their fieldwork. Today, the NSF still provides funding and support for scientific anthropological research including archaeology,
archaeometry, biological anthropology, cultural anthropology, and linguistics. ==Honors and leadership roles==
