خلاصه	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.	The Need for Cognition in Politics Scale measures individual differences in the tendency to engage in and enjoy effortful cognitive processing related to political information and decision-making. Originally conceptualized by Cacioppo and Petty (1982), the trait reflects whether individuals seek, process, and rely on substantive information when forming political attitudes. High NFC individuals prefer detailed policy discussions; low NFC individuals may rely on heuristics, endorsements, or emotional appeals.
