Podsumowanie	The Post-Materialism Index, developed by Ronald Inglehart (1971), classifies individuals as materialist, postmaterialist, or mixed based on the priority they assign to physical and economic security versus self-expression, belonging, and quality of life. It operationalizes Inglehart's silent-revolution thesis that prosperity and security in postwar democracies caused an intergenerational shift from materialist to postmaterialist value priorities.	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.
