A core assumption of deliberative theory is that deliberation helps generate legitimate decisions in the political sphere and beyond. In this context, this paper seeks to investigate whether deliberation increases citizens perception of regime legitimacy, which is conceptualized and measured as regime support.

To this end, deliberation and its relationship with regime support are examined across the world by combining multiple cross-national survey projects (World Values Survey, Asian Barometer, Afrobarometer, Latinobarómetro, AmericasBarometer and European Social Survey) covering more than 100 countries and over 300,000 individual respondents. As this paper is the first known to the authors that examines the effects of deliberation on regime support in a cross-country design, the used deliberation measurement, the Deliberative Component Index from the “Varieties of Democracy”-Project, is thoroughly examined and analyses are conducted for its components as well. Given that self-reported regime support is expected to be biased in countries where freedom of discussion is inhibited, a weight is applied to account for possible distortions in the survey data.

The results of the multilevel regression analysis indicate that deliberation fulfills its legitimacy claim by increasing regime support first and foremost in democracies. The evidence for non-democracies and the complete sample is ambiguous and less robust although it points in the same direction. A possible limitation of the study is the high correlation between the used deliberation measurements and democracy indices which might indicate that the measurement does not accurately reflect the grade of deliberation in each country. Nevertheless, some interesting deviations in these correlations could be found between the subsamples, as well as in regard to the index and its components. In order to arrive at robust results, more sensible ways to measure deliberation on the country level seem necessary. It is further suggested that following studies and survey projects in the field should find methods to remedy possible bias in self-reported regime support, especially in countries with more authoritarian regimes.

The findings of this paper can hopefully be used as a starting point for more detailed investigation of the relationship between deliberation and regime legitimacy in the future.
