Personality traits of world leaders and differential policy responses to the COVID-19 pandemic.

The current study assesses the extent to which government leaders' personality traits are related to divergent policy responses during the pandemic. To do so, we use data from the Oxford COVID-19 Government Response Tracker initiative (OxCGRT) to measure the speed and magnitude of policy responses across countries and NEGex, a dataset that maps the personality traits of current heads of government (presidents or prime ministers) in 61 countries. We find that world leaders scoring high on "plasticity" (extraversion, openness) were quicker to implement travel restrictions and provide financial relief as well as offered a stronger response in general (average overall response). Whereas, leaders scoring high on "stability" (conscientiousness, agreeableness, emotional stability) offered both quicker and stronger financial relief. Our findings underscore the need to account for the personality of decision-makers when exploring decision-making during the pandemic, and during similar crisis situations.

Exploring the Effect of Collective Cultural Attributes on Covid-19-Related Public Health Outcomes.

Infections and deaths associated with COVID-19 show a high degree of heterogeneity across different populations. A thorough understanding of population-level predictors of such outcomes is crucial for devising better-targeted and more appropriate public health preparedness measures. While demographic, economic, and health-system capacity have featured prominently in recent work, cultural, and behavioral characteristics have largely been overlooked. However, cultural differences shape both the public policy response and individuals' behavioral responses to the crisis in ways that can impact infection dynamics and key health outcomes. To address this gap, we used meta-analytic methods to explore the global variability of three public health outcomes (i.e., crude test positivity, case/infection fatality, and mortality risk) during the first wave of the pandemic. This set of analyses identified several cultural/behavioral attributes (e.g., uncertainty avoidance and long-term vs. short-term normative orientation) as independent predictors of public health outcomes after adjusting for key demographic, political, economic, and health-system-related predictors; which were robust in sensitivity analyses. In conclusion, this study clearly demonstrates that cultural attributes do in fact account for some of the global disparities in COVID-19-attributed health outcomes. As a consequence, policymakers should more explicitly consider a society's cultural attributes alongside other important parameters such as demographic characteristics and health system constraints in order to develop better tailored and more effective policy responses.
