In sociological thermodynamics, a Müller stability ratio is the ratio of attraction-to-repulsion in a stable social aggregate. [1] The term is modeled on analogy to the Gottman stability ratio (5/1), in which stable long-term marriages have a 5-to-1 ratio of attraction to repulsion in the exchange force of their bond, but named after Venezuelan chemical engineer Erich Müller for his outline of the subject in the 1998 article “Human Societies: a Curious Application of Thermodynamics”.
