Sintesi	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.	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.
