Sammanfattning	The Political Knowledge Scale measures the range of factual information about politics that citizens hold and can retrieve, operationalized as a battery of factual quiz items. Delli Carpini and Keeter (1993, 1996) established the canonical short batteries (often five items) and argued that general political knowledge, not domain-specific information, is the most useful and reliable construct for survey research.	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.
