Controlled comparison is a methodological approach in anthropology, archaeology, and the social sciences that involves systematically comparing a small number of societies, cultures, or cases under carefully selected and limited variables. It is designed to highlight similarities and differences while minimizing confounding factors.
๐ Definition
- Controlled Comparison: A comparative method that restricts the scope of analysis to cases with shared baseline characteristics, allowing researchers to isolate the effects of specific variables.
- Purpose: To avoid overly broad or misleading comparisons by focusing on contexts that are similar enough to yield meaningful contrasts.
๐ Characteristics
- Selective Case Choice: Researchers choose societies or contexts that share certain features (e.g., ecological setting, subsistence base, political organization).
- Variable Isolation: By holding some factors constant, differences in other variables can be more clearly observed.
- Small-N Analysis: Typically involves a limited number of cases rather than large-scale cross-cultural surveys.
- Middle Range: Falls between single-case ethnography and global comparative studies.
๐ Anthropological Significance
- Kinship Studies: Controlled comparison has been used to examine marriage rules across societies with similar descent systems.
- Political Anthropology: Comparing chiefdoms in different ecological zones to see how environment shapes hierarchy.
- Archaeology: Comparing settlement patterns in regions with similar resources but different cultural traditions.
- Theory Building: Helps refine hypotheses by showing how specific variables influence outcomes.
๐ Examples
- Evans-Pritchard & Fortes (1940s): Compared African kinship systems by controlling for lineage-based organization.
- Marshall Sahlins: Used controlled comparison to study economic systems in societies with similar subsistence bases.
- Archaeological Case Studies: Comparing mound-building cultures in North America under similar environmental conditions but different social structures.
โจ Summary
Controlled comparison is a focused comparative method that limits the scope of cases to isolate variables, making it a powerful tool for theory-building in anthropology and archaeology. It balances depth (like ethnography) with breadth (like global surveys), offering nuanced insights into cultural variation.
