Leaders decide to engage diplomatically with their foreign peers for various reasons but, given their limited time and resources, they have to choose which peers to prioritize. As such, the study of international diplomatic visits helps shed light on a government's foreign policy approach and better understand its priorities in how it conceives and builds foreign relations. While the literature on diplomatic engagements has largely debated its drivers and effects, the role of domestic influences, in particular of party politics, has remained understudied. We address this gap and investigate the party politics of diplomatic engagements leveraging a new dataset on Italy's high-level international bilateral diplomatic visits in 2000–2023. Our findings show that partisan differences influence not only the overall frequency of such engagements, following curvilinear left–right patterns, but also the political regimes that left- and right-wing governments prioritize in such endeavours, exposing the lower importance right-wing parties assign to democratic principles when managing their countries' foreign relations, as these governments are systematically more likely to interact with authoritarian regimes than with democracies.

An intriguing study concluded that political conservatives exhibited enhanced self-control using the Stroop task [Clarkson et al.: The self-control consequences of political ideology. Proc. Natl. Acad. Sci. U.S.A, 112(27): 8250–8253 (2015)]. We preregistered our plans to re-examine this finding using a larger, representative, incentivized, and ideologically balanced sample (n = 476). Across a variety of specifications, we report a consistent null effect of ideology on Stroop response latencies and the Stroop interference effect. These findings suggest that the previously reported result may not generalize. We conclude that there is no causal relationship between political ideology and self-control, as measured by the Stroop task.

During the global COVID-19 pandemic, many countries have expanded the level and coverage of current social insurance and social assistance programs as well as implemented new programs. Based on three separate datasets, V-Dem V-Party dataset; fourteen structured expert interviews; and a dataset of 114 social security measures, we study the link between the welfare regime, pandemic-related social policy measures, and incumbents’ ideological stand. Does the pandemic-related social policy measures mirror the political attitudes of the incumbents? What role did the welfare regime play? We scrutinise eight OECD countries (Denmark, Finland, Germany, Netherlands, Norway, Sweden, UK, and the US) representing three different welfare regimes: corporatist-conservative countries, liberal countries, and socio-democratic countries. The key findings of this article show that the pandemic-related social policy measures did not mirror the political attitudes of the incumbents.

The ideological nature of public health is a problem for the profession. Ideological uniformity in the field of public health undermines scholars’ and officials’ legitimacy and compromises their ability effectively to prevent death and disease. I first provide some evidence that public health is ideological and then I argue that the ideology of public health is counterproductive. Additionally, public officials are also likely to violate people’s rights in trying to advance their ideology through public health policy. In light of these moral considerations against the ideological nature of public health, there are compelling reasons for people to resist the expanding scope of public health insofar as it consists in the further imposition of this counterproductive and harmful ideology. I therefore conclude that the profession would be more effective and just if public health officials and scholars focused more narrowly on improving health outcomes instead of promoting their broader ideological agenda through public health policy.

There is growing concern about the impact of declining political trust on democracies. Psychological research has introduced the concept of epistemic (mis)trust as a stable disposition acquired through development, which may influence our sociopolitical engagement. Given trust’s prominence in current politics, we examined the relationship between epistemic trust and people’s choices of (un)trustworthy political leaders. In two representative samples in the UK and US (N = 1096), we tested whether epistemic trust predicts political leader choices through three political dimensions: dogmatism, political trust, and ideology. Although epistemic trust did not directly predict choices of political leaders, it predicted dogmatism and political ideology, which in turn predicted choices of political leaders. A network analysis revealed that epistemic trust and political dimensions only interact through their common connection with dogmatism. These findings suggest that cognitive and affective development may underlie an individual’s political ideology and associated beliefs.

We examine the likely acceptance of the COVID-19 vaccine in the period prior to political polarization around vaccine mandates. Two representative cross-sectional surveys of 1,000 respondents were fielded in August and December 2020. The surveys included items about the COVID-19 vaccine and vaccine mandates. Respondents self-identifying as liberal were the least likely to believe the vaccine had undisclosed harmful effects (p< .001), conservatives were the most likely (p < .001), and moderates fell in between. Individuals with a bachelor’s degree were less likely to think the vaccine had undisclosed harmful effects than individuals without a bachelor’s degree (p < .001), and 60.5% of those individuals did not support a government vaccine mandate. Political ideology was more often strongly associated with avoiding government involvement compared to education level. In summary, both liberal political ideology and higher education were significantly associated with endorsing intended vaccine uptake. We discuss these results in terms of positive versus negative rights.

We use data from the new and nationally representative National Survey of Religious Leaders, supplemented with the 2018 General Social Survey, to examine the extent to which clergy are politically aligned with people in their congregations. Two assessments of alignment—clergy reports of how their political views compare to the political views held by most people in their congregations, and comparisons between clergy and lay voting preferences in the 2016 election—yield the same findings. Clergy in Black Protestant and predominantly white evangelical churches are much more likely to be politically aligned with their people than are Catholic or, especially, white mainline Protestant clergy, who often are more liberal than their people. Contrary to media reports suggesting that evangelical clergy are now likely to be less conservative than their people, the vast majority are either politically aligned with, or more conservative than, their members.

Political conservatives' opposition to COVID-19 restrictions is puzzling given the well-documented links between conservatism and conformity, threat sensitivity, and pathogen aversion. We propose a resolution based on the Dual Foundations Theory of ideology, which holds that ideology comprises two dimensions, one reflecting trade-offs between threat-driven conformity and individualism, and another reflecting trade-offs between empathy-driven cooperation and competition. We test predictions derived from this theory in a UK sample using individuals' responses to COVID-19 and widely-used measures of the two dimensions – ‘right-wing authoritarianism’ (RWA) and ‘social dominance orientation’ (SDO), respectively. Consistent with our predictions, we show that RWA, but not SDO, increased following the pandemic and that high-RWA conservatives do display more concerned, conformist, pro-lockdown attitudes, while high-SDO conservatives display less empathic, cooperative attitudes and are anti-lockdown. This helps explain paradoxical prior results and highlights how a focus on unidimensional ideology can mask divergent motives across the ideological landscape.

Right-wing ideology and cognitive ability, including objective numeracy, have been found to relate negatively. Although objective and subjective numeracy correlate positively, it is unclear whether subjective numeracy relates to political ideology in the same way. Replicating and extending previous research, across two samples of American adults (ns= 455, 406), those who performed worse on objective numeracy tasks scored higher on right-wing authoritarianism (RWA) and social dominance orientation (SDO), and they self-identified as more conservative on general, social, and economic continua. Controlling for objective numeracy, subjective numeracy related positively to measures of right-wing ideologies. In other words, those who strongly (vs. weakly) endorsed right-wing ideologies believed they are good with numbers yet performed worse on numeracy tasks. We discuss implications for the opposing direction of associations between ideology with objective versus subjective numeracy and similarities with literature on overconfidence.

Previous studies relating low-effort or intuitive thinking to political conservatism are limited to Western cultures. Using Turkish and predominantly Muslim samples, Study 1 found that analytic cognitive style (ACS) is negatively correlated with political conservatism. Study 2 found that ACS correlates negatively with political orientation and with social and personal conservatism, but not with economic conservatism. It also examined other variables that might help to explain this correlation. Study 3 tried to manipulate ACS via two different standard priming procedures in two different samples, but our manipulation checks failed. Study 4 manipulated intuitive thinking style via cognitive load manipulation to see whether it enhances conservatism for contextualized political attitudes but we did not find a significant effect. Overall, the results indicate that social liberals tend to think more analytically than conservatives and people’s long term political attitudes may be resistant to experimental manipulations.

Recent evidence suggests that Americans’ beliefs about upward mobility are overly optimistic. Davidai & Gilovich (2015a), Kraus & Tan (2015), and Kraus (2015) all found that people overestimate the likelihood that a person might rise up the economic ladder, and underestimate the likelihood that they might fail to do so. However, using a different methodology, Chambers, Swan and Heesacker (2015) reported that Americans’ beliefs about mobility are much more pessimistic. Swan, Chambers, Heesacker and Nero (2017) provide a much-needed summary of these conflicting findings and question the utility of measuring population-level biases in judgments of inequality and mobility. We value their summary but argue that their conclusion is premature. By focusing on measures that best tap how laypeople naturally think about the distribution of income, we believe that researchers can draw meaningful conclusions about the public’s perceptions of economic mobility. When more ecologically representative measures are used, the consistent finding is that Americans overestimate the extent of upward mobility in the United States. To explain the divergent findings in the literature, we provide evidence that the methods used by Chambers et al. (2015) inadvertently primed participants to think about immobility rather than mobility. Finally, using a novel method to examine beliefs about economic mobility, we show that Americans indeed overestimate the degree of mobility in the United States.

Several scholars have suggested that Americans’ (distorted) beliefs about the rate of upward social mobility in the United States may affect political judgment and decision-making outcomes. In this article, we consider the psychometric properties of two different questionnaire items that researchers have used to measure these subjective perceptions. Namely, we report the results of a new set of experiments (N = 2,167 U.S. MTurkers) in which we compared the question wording employed by Chambers, Swan and Heesacker (2015) with the question wording employed by Davidai and Gilovich (2015). Each (independent) research team had prompted similar groups of respondents to estimate the percentage of Americans born into the bottom of the income distribution who improved their socio-economic standing by adulthood, yet the two teams reached ostensibly irreconcilable conclusions: that Americans tend to underestimate (Chambers et al.) and overestimate (Davidai & Gilovich) the true rate of upward social mobility in the U.S. First, we successfully reproduced both contradictory results. Next, we isolated and experimentally manipulated one salient difference between the two questions’ response-option formats: asking participants to divide the population into either (a) “thirds” (tertiles) or (b) “20%” segments (quintiles). Inverting this tertile-quintile factor significantly altered both teams’ findings, suggesting that these measures are inappropriate (too vulnerable to question-wording and item-formulation artifacts) for use in studies of perceptual (in)accuracy. Finally, we piloted a new question for measuring subjective perceptions of social mobility. We conclude with tentative recommendations for researchers who wish to model the causes and consequences of Americans’ mobility-related beliefs.

We conducted additional analyses of Pennycook et al.’s (2015, Study 2) data to investigate the possibility that there would be ideological differences in “bullshit receptivity” that would be explained by individual differences in cognitive style and ability. As hypothesized, we observed that endorsement of neoliberal, free market ideology was significantly but modestly associated with bullshit receptivity. In addition, we observed a quadratic association, which indicated that ideological moderates were more susceptible to bullshit than ideological extremists. These relationships were explained, in part, by heuristic processing tendencies, faith in intuition, and lower verbal ability. Results are inconsistent with approaches suggesting that (a) there are no meaningful ideological differences in cognitive style or reasoning ability, (b) simplistic, certainty-oriented cognitive styles are generally associated with leftist (vs. rightist) economic preferences, or (c) simplistic, certainty-oriented cognitive styles are generally associated with extremist (vs. moderate) preferences. Theoretical and practical implications are briefly addressed.

Davidai and Gilovich (2018) contend that (a) Americans tend to think about their nation’s income distribution in terms of quintiles (fifths), and (b) when Americans’ perceptions of socio-economic mobility rates are measured properly (e.g., by asking online survey respondents to guess upward-mobility rates across quintiles), a trend of overestimation (too much optimism concerning the number of people who manage to transcend poverty) will emerge. In this reply, we hail Davidai and Gilovich’s new data as novel, important, and relevant to the former (a), but we doubt that they can support the latter (b) claim about population-level (in)accuracy. Namely, we note that even if mobility-rate perceptions could be measured perfectly, inferences about the accuracy of those perceptions still depend on a particular comparator—a point-estimate of the "true" rate of upward social mobility in the U.S. against which survey respondents’ guesses are evaluated—that is itself an error-prone estimate. Applying different established comparators to survey respondents’ guesses changes both the direction and magnitude of previously observed overestimation effects. We conclude with a challenge: researchers who wish to compute the average distance between socio-economic perceptions and socio-economic reality must first select and justify a fair comparator.

How does political ideology affect the processing of information incongruent with one’s worldview? The disagreement in prior research about this question lies in how one’s ideology interacts with cognitive ability to shape motivated numeracy or the tendency to misinterpret data to confirm one’s prior beliefs. Our study conceptually replicates and extends previous research on motivated numeracy by testing whether monetary incentives for accuracy lessen motivated reasoning when high- and low-numeracy partisans interpret data about mask mandates and COVID-19 cases. This research leverages the ongoing COVID-19 crisis, as Americans are polarized along party lines regarding an appropriate government response to the pandemic.

Sleep research presents an important frontier of discovery for political science. While sleep has largely been neglected by political scientists, human psychology is inextricably linked with sleep and so political cognition must be as well. Existing work shows that sleep is linked to political participation and ideology, and that contentious politics can disrupt sleep. I propose three directions for future research—on participatory democracy, on ideology, and on how context shapes sleep-politics links. I also note that sleep research intersects with the study of political institutions, of war and conflict, of elite decision-making, and of normative theory. In short, political scientists across subfields can and should consider whether and how sleep influences political life in their area of expertise and how to influence relevant policies. This new research agenda will enrich our theories of politics and enable us to identify pressing areas for policy interventions to revitalize our democracy.

Older adults have been statistically proved to be at a higher risk of getting severely infected by the coronavirus COVID-19, evoking sweeping narratives of compassionate ageism surrounding them in different discourses. By analysing the media content, scholars from different areas have alerted us about the amplified ageism aroused by the pandemic crisis. However, we are still short of empirical evidence to learn how ageism is constructed in diverse sociocultural contexts in the wake of this global pandemic crisis. This study provides the case of Hong Kong to reflect on how ageism, as a set of social inequalities, is constructed. By examining 814 articles collected from the three most popular newspapers with different political orientations in Hong Kong, this study uses quantitative and qualitative content analysis to examine how older people have been generally represented. Then it further compares how these representations have been influenced by the media's liberal or conservative preferences. Third, it examines the relationship between the political orientation of newspapers and how different forms of ageism are constructed. The findings indicate that despite the liberal or conservative inclination of the three newspapers, they portray the older population as frail, dependent and deprived not only at the biomedical level but in all aspects of life. This study also reveals that the newspapers with a populist inclination in both camps have shown more hostile attitudes in representing compassionate ageism. In contrast, liberal and conservative-leaning media affirmed the government's dominant role in taking full responsibility for caring for the older population. The findings indicate that the polarised ageism frame cannot fully explain the underpinnings of ageism and implied policy processing in different contexts.

Left-leaning and right-leaning governments hold opposing views on economic policy, resulting in disparities in economic behaviours and outcomes. Given this context, we explore the effect of political ideology on domestic credit using an unbalanced panel data of 29 countries from 1960 to 2014. Our empirical analysis shows that left-leaning governments reduce total domestic credit allocations. Also, we find that right-leaning governments provide more credit to the private sector, while left-leaning governments prefer to boost domestic credit to the public sector. In a further analysis, we show that political parties and their domestic credit strategies remain unchanged even during electoral periods. Our novel insights, that are robust to alternative measures, samples, and a set of econometric identifications, contribute to the literature on partisan politics and lending behaviour.
