This article explores how populist attitudes are correlated with foreign policy postures at the public level in four European countries: France, Germany, Great Britain, and Italy. We provide first evidence adjudicating between two rivalling perspectives. One perspective focuses on the ideational core of populism and argues that it entails substantive beliefs and values that may inform foreign policy preferences – just like any other ideology. Another perspective focuses on the thin-centredness of populism and argues that no policy implications can be derived from populist ideas. Analysing original survey data, we find strong and consistent associations of populist attitudes with two foreign policy postures, militant internationalism and isolationism, and weaker and less systematic associations with two others, cooperative internationalism and global justice orientations. Importantly, these patterns are independent of host ideologies. We discuss the implications of these findings for the question of how “thick” populism is and what that may mean for the politics of (European) foreign policies in times of a continuing populist Zeitgeist.

The literature on populist attitudes frequently makes one of two assumptions: populist attitudes are either stable or unstable. However, few studies have examined these diverging assumptions empirically. We use panel data collected over six panel waves between 2017 and 2021 in Germany to assess the stability of populist attitudes. Integrating inter-individual stability (variable-centred) and intra-individual stability (individual trajectories), we find that populist attitudes are neither fully stable (trait) nor fully flexible (state). For example, some respondents constantly changed their view on populism while the attitudes in one out of three individuals remained stable. We also explore empirical consequences and find that populist attitudes are more closely linked to vote choice when they are stable. Accordingly, we argue for a more nuanced understanding of the dynamics of populist attitudes, both at the variable and individual levels, where these attitudes are stable and consequential for only a subset of individuals.

Populist discourse—which tends to benefit anti-systemic parties—has been on the rise in the world’s democratic states. Powerful non-democratic states have both the means and the incentive to spread such discourse to democratic states. We clarify the incentives illiberal states have to produce such communication, and delineate how this type of political communication fuses traditional state-to-state propaganda with election interventions. We draw on the case of Kremlin-sponsored communication on the issue of refugees in Germany to illustrate the mechanisms through which the discourse operates in target countries. We create a corpus of over a million news stories to identify the prevalence of illiberal discourse and its timing relative to Germany’s elections. We show that the Kremlin intervened in the 2017 federal elections by promoting refugee stories over and above the rate at which German outlets did. We discuss the broader implications for the use of directed political communication as a form of election intervention.

Democracies without democrats are not sustainable. Yet, recent studies have argued that Western citizens are turning their backs on the system of self-governance, thereby eroding the societal foundations of consolidated democracies. This study contributes to discussions about citizen support of democracy by (1) analyzing new cross-national survey data in 18 European countries that facilitate assessments of the temporal and geographical generalizability of previous findings, (2) disentangling age, cohort and period effects, thereby aligning the analytical methods with the theoretical arguments and (3) transparently reporting all evidence derived from pre-registered analyses to avoid cherry-picked findings. The findings show that citizens of consolidated democracies continue to endorse self-governance. Yet in some (but not all) countries, there is evidence of a growing number of ‘democrats in name only’, particularly among the young generation. These findings suggest a second phase in research on democratic fatigue that broadens the analytical scope for the multi-faceted nature of democratic support.

Multidimensional concepts are non-compensatory when higher values on one component cannot offset lower values on another. Thinking of the components of a multidimensional phenomenon as non-compensatory rather than substitutable can have wide-ranging implications, both conceptually and empirically. To demonstrate this point, we focus on populist attitudes that feature prominently in contemporary debates about liberal democracy. Given similar established public opinion constructs, the conceptual value of populist attitudes hinges on its unique specification as an attitudinal syndrome, which is characterized by the concurrent presence of its non-compensatory concept subdimensions. Yet this concept attribute is rarely considered in existing empirical research. We propose operationalization strategies that seek to take the distinct properties of non-compensatory multidimensional concepts seriously. Evidence on five populism scales in 12 countries reveals the presence and consequences of measurement-concept inconsistencies. Importantly, in some cases, using conceptually sound operationalization strategies upsets previous findings on the substantive role of populist attitudes.

National identities are often conceived of as factors that lend structure and stability to citizens’ political opinions on issues such as immigration. While citizens who define national membership in ethno-cultural terms are less likely to support immigration, those with a civic conception are more likely to do so. The authors propose that defining national identity along both ethno-cultural and civic lines may give rise to conflicting considerations, leading people to experience ambivalence, implying that national identities may serve less as a stabilizing force than suggested by previous research. Findings from heterogeneous choice models and a unique survey experiment show that German citizens with mixed conceptions of national identity had more variable and more malleable opinions than individuals with ideal-type conceptions during the 2015/2016 European refugee crisis. The findings point to an identity-based source of ambivalence and extend current understandings of how people form attitudes towards immigration.
