Size, Complexity, and Organizational Variation: A Comparative Approach

Abstract

In 1963, Melvin Ember illustrated the overarching cross-cultural relationship between societal scale (specifically, maximal community size) and hierarchical complexity. Yet this study (and subsequent ones) found much less regularity in the size-complexity relationship when focused down on human groupings of less extensive/narrower size ranges. Here, it is argued that this lack of a more precise fit requires the consideration of a third key parameter, different modes of integration or interpersonal connectivity. Comparative findings (both synchronic and diachronic) are marshaled to make the case that integrative differences mediate the overarching relationship between demographic size and political complexity. It is proposed that when they are small, groups that operate more collectively often dampen the emergence of decision-making hierarchies; alternatively large, more collective, or democratic formations may necessitate greater administrative or hierarchical political complexity per capita than is found in more autocratic groups of comparable size.
