요약	Open-ended political response coding is the systematic content analysis of verbatim survey answers, classically the American National Election Studies likes/dislikes about parties and candidates, into a categorical scheme so they can be analyzed quantitatively. It applies content-analysis methodology (Krippendorff, 2004) to capture the substance and sophistication of citizens' political thinking that closed-ended items cannot.	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.
