The authors of this article attempt to describe in detail the determinants and structure of the beliefs and views of Polish society on a liberal to anti-liberal values continuum. The first research objective was to determine the extent of social and economic freedom that respondents expect in their relations with others and in their relations with state institutions. In addition, the authors wanted to identify the socio-demographic characteristics that significantly differentiate these liberal orientations, as well as the factors that independently determine the adoption of liberal views. The detailed hypotheses were verified based on an analysis of data collected in a nationwide telephone survey (CATI) conducted on a representative sample of 1,000 adult Polish citizens. The survey used an original questionnaire consisting of 31 quantitative scales, which were used to construct the Liberalism/Libertarianism Index (LLI) and to categorize respondents into “Polish Liberals” and “Polish Libertarians.” Higher index values indicate stronger and more consistent liberal attitudes in economic as well as axiological (social) terms. More liberal orientations were found to be held by respondents declaring higher incomes, younger, better educated, and less religious, although only age, some party preferences, and religious practices act as independent predictors of LLI.
