This paper presents the Tragic Triad Decision Framework (ttdf), a novel inferential and inductive methodology for decision-making under conditions of moral complex- ity, competing values, and irreducible uncertainty. Drawing systematically from the philosophical architectures embedded in the works of the three major Athe- nian tragediansAeschylus, Sophocles, and Euripideswe formalize ve founda- tional axioms, ve theorems with corollaries, seven operational rules, and a compre- hensive decision matrix. The framework synthesizes Aeschylean systemic-temporal reasoning, Sophoclean ethical-agential deliberation, and Euripidean psychological- practical insight into an integrated decision methodology applicable to contempo- rary strategic, organizational, and policy contexts. We demonstrate that ancient tragic wisdom, when properly formalized, oers rigorous analytical tools for navi- gating the tragic choices characteristic of high-stakes decision environments where all options involve sacrice of legitimate values.
