สรุป	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.	The Political Ideology Scale measures individual self-placement on a left-right political spectrum, capturing fundamental preferences for government role, economic organization, and social values. The single-item self-placement measure (most common) asks respondents to rate themselves on a 0-10 or 0-100 continuum; multi-item versions assess distinct ideological dimensions (economic policy, social policy, nationalism). The left-right axis remains the dominant organizing principle of political competition globally, predicting party choice, policy preferences, and electoral behavior despite critiques that it oversimplifies multidimensional political space.
