概要	Ideological constraint analysis measures the degree to which an individual's or a public's political attitudes hang together in a coherent, predictable structure, the extent to which knowing a person's position on one issue lets you predict their positions on others. Introduced by Converse (1964) as the defining feature of a belief system, it is assessed through inter-item correlations, factor/latent-dimension models, and constraint indices.	Political sophistication measurement assesses the size, range, and organization of an individual's political belief system, the degree to which a person's political cognitions are numerous, wide-ranging, and well integrated. Luskin (1987) developed rigorous operationalizations, and Zaller (1992) showed that political awareness, his preferred sophistication indicator, governs how citizens receive and accept political messages.
