| Sintesi≠ | Political ideology scaling estimates actors' positions on one or more latent ideological dimensions from their observed choices, most often legislators' roll-call votes, but also survey responses and donations. The dominant methods are Poole and Rosenthal's NOMINATE (1985) and the Bayesian item-response-theory (IRT) approach of Clinton, Jackman and Rivers (2004), which place legislators and the proposals they vote on in a common spatial map. | 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. |
