Political science meets physical science: The shared concept of stability.

A biophysical chemist and a political scientist team up to explore striking parallels between the requisites of "stability" and the causes of instability within both the cellular/molecular world of biophysical chemistry and the world of social and political organization of self-assembled, societal structures, such as sovereign states and institutions. The structure, function, and organizational similarities of such parallelisms are particularly noteworthy, given that human agency introduces greater contingency in the sociopolitical world than do the "laws of Nature" in the natural-scientific world. In this perspective piece, we critically identify and analyze these parallels between the natural and the social realms through the prism of the shared concept of stability, including causal factors that embrace the full "stability spectrum" from instability to stability. This spectrum includes the crucial bridging, time-dependent, intermediate, kinetic state of "metastability." Our analyses reveal that, in the microscopic/molecular world of the physical sciences, the thermodynamic and kinetic characterizations of the stabilities and transformations between physiochemical "states" exhibit cognate properties and features in the macroscopic world of sociopolitical arenas in ways that reflect a greater than traditionally assumed continuity between Nature and society. Select examples from the natural and social realms are presented and elaborated on to illustrate these parallelisms, while underscoring the striking similarities in their functional consequences.
