概要	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.	Leadership Trait Analysis (LTA), developed by Margaret Hermann (1980), profiles political leaders' personalities from their spoken words to explain and anticipate foreign-policy behavior. It scores seven characteristics — the belief in one's ability to control events, the need for power, conceptual complexity, self-confidence, distrust of others, in-group bias, and task focus — from patterns in a leader's verbal material, norms them against reference groups, and combines them into broader leadership styles. It is a leading at-a-distance method for assessing leaders who cannot be interviewed or tested directly.
