সারসংক্ষেপ	Prospect theory, the behavioral account of choice under risk developed by Kahneman and Tversky, has been applied across international relations to explain foreign-policy decisions that expected-utility models struggle with. As surveyed and assessed by Jack Levy (1997), the key ideas are that leaders evaluate outcomes as gains and losses relative to a reference point rather than in absolute terms, that losses loom larger than equivalent gains (loss aversion), and that people are risk-averse for gains but risk-seeking to avoid losses. These departures from rationality illuminate why states gamble to recover losses and take excessive risks to defend the status quo.	Operational code analysis measures a political leader's belief system — their fundamental assumptions about the nature of politics and the best strategies for pursuing goals — from the leader's own words. Originating in Nathan Leites's study of the Bolshevik mindset and reformulated by Alexander George (1969) into a structured set of philosophical and instrumental questions, it later became a quantitative method through the Verbs in Context System (VICS). By coding how a leader talks about conflict, cooperation, control, and risk, analysts characterize the cognitive framework through which that leader interprets the world and chooses action.
