Flexible Practice Theory (FPT): A Mid-Range Mathematical Model of Adaptive Consumption across Interdisciplinary Contexts

The "value-action gap"—the pervasive phenomenon wherein individuals hold strong normative beliefs yet fail to act upon them—remains a persistent theoretical challenge across the social sciences. While traditional sociological frameworks offer profound insights into long-term behavioural reproduction, they frequently struggle to account for the rapid, context-dependent fluidity of modern human action. This paper introduces Flexible Practice Theory (FPT), an analytical mid-range socio-mathematical framework designed to address this theoretical void and presents an exploratory conceptual framework intended to stimulate academic discussion rather than provide a fully validated predictive model. By modelling human action as a real-time negotiation between internal dispositions (H, V, I), structural constraints (Cs), and a binary cultural governor (C), FPT offers a preliminary analytical baseline for behavioral analysis. This paper outlines the mathematical and analytical architecture of the model, demonstrates its operationalization through diverse real-world scenarios, and explores its potential as a collaborative foundation for interdisciplinary research. At this stage, the model should be interpreted as a conceptual and analytical proposal rather than a finalized predictive framework. Its primary purpose is to stimulate discussion and guide future empirical testing.
