Ideological Ambiguity and Political Spectrum

TL;DR

This paper explores how political parties' ideological positions relate to their use of ambiguity, revealing a non-linear pattern where centrist parties tend to be more ambiguous, supported by data from European parties and economic indicators.

Contribution

It introduces a novel theory explaining the non-monotonic relationship between ideology and ambiguity, emphasizing the perceived risk and electoral advantages of centrist parties.

Findings

Centrist parties are perceived as less risky by voters.

A non-monotonic (inverted U-shaped) relationship exists between ideology and ambiguity.

Electoral outcomes and economic indicators support the proposed theory.

Abstract

This study examines the relationship between ambiguity and the ideological positioning of political parties across the political spectrum. We identify a strong non-monotonic (inverted U-shaped) relationship between party ideology and ambiguity within a sample of 202 European political parties. This pattern is observed across all ideological dimensions covered in the data. To explain this pattern, we propose a novel theory that suggests centrist parties are perceived as less risky by voters compared to extremist parties, giving them an advantage in employing ambiguity to attract more voters at a lower cost. We support our explanation with additional evidence from electoral outcomes and economic indicators in the respective party countries.
