สรุป	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.	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.
