Description
This monograph develops a unified theory of decision, belief, and social interaction by reinterpreting the major paradoxes of rationality as manifestations of a single underlying structure: a cognitive field. Beginning with the St. Petersburg paradox and extending through the Allais paradox, Ellsberg paradox, Parrondo paradox, the Traveler's Dilemma, and collective phenomena such as the Condorcet paradox and Arrow's impossibility theorem, the work demonstrates that apparent inconsistencies in rational behavior are not anomalies but projections of deeper geometric, dynamic, and epistemic properties. The central contribution is the replacement of function-based models of rationality with a field-theoretic framework, in which decisions are modeled as configurations evolving under a global functional that integrates local payoffs, configurational structure, epistemic uncertainty, interaction effects, antagonism, and normativity. Within this framework, classical assumptions - such as additivity, independence, transitivity, equilibrium sufficiency, and ergodicity - are shown to hold only in restricted regions of the field. Their violations correspond to identifiable geometric features, including curvature, non-integrability, non-commutativity, and phase transitions.
