Research Summary: Multidimensional Political Attitudes and Polarization Across 141 Countries

Recent research challenges the traditional understanding of political polarization, revealing that the single left-right axis developed in Western democracies does not adequately describe political divisions across most of the world. A new study, harmonizing data from 1.14 million individuals across 141 countries, identifies four key dimensions: social liberalism, economic left-right, democratic commitment, and anti-elite sentiment, suggesting a more nuanced approach is required to understand global political landscapes.

Why it matters

Understanding the true nature of political attitudes and polarization is crucial for effective governance, policy formulation, and international relations. Relying on an oversimplified left-right spectrum can lead to misinterpretations of societal dynamics, hindering strategic planning and stakeholder engagement efforts globally.

Key insights

• Societies are widely perceived as increasingly polarized, but prior measurement of issue polarization primarily relied on a single left-right political axis.
• The applicability of a single left-right axis to describe political division beyond Western democracies has been largely untested due to a lack of multi-dimensional cross-national attitude surveys.
• Researchers harmonized 1,299 items from nine cross-national survey programs and 23 national election studies, encompassing 1.14 million individuals.
• The analysis identifies four distinct dimensions of political attitudes: social liberalism, economic left-right, democratic commitment, and anti-elite sentiment.
• A single left-right axis is deemed insufficient to describe political division in the majority of countries analyzed, highlighting the complexity of global political alignments.
