An integrative social identity model of populist leadership

In recent years, the questions of what populism is and how populist leaders mobilize their followers have been the subject of extensive debate. While the social psychology literature holds unique theoretical tools that can be used to explain leader-follower dynamics, these have not yet been applied to understand populism and populist leadership. In this paper, we aim to discuss populism as a social-psychological concept and provide a comprehensive approach to examine the interactions between populist leaders and followers by using the identity leadership model (see New Psychology of Leadership, Haslam et al., 2020). Accordingly, we propose an integrative model in which we suggest that populism should be treated as a social-psychological concept based on (i) strong ingroup identification; (ii) interactive leadership processes that open spaces to followers for enacting their ingroup identity that end up with mobilization against vertical (e.g., elites) and horizontal (e.g., minorities, refugees, opponents) outgroups; (iii) leader's ingroup prototypicality and identity entrepreneurship that is boosted by using shared grievances, narratives of collective victimhood, and the destabilization of mainstream opponent leaders. Furthermore, by discussing real-world examples and recent studies, we aim to show how the content of what it means to be ‘us’ and what is seen as moral to ‘us’ can be shaped by populist leaders for mobilization

Global economic burden of unmet surgical need for appendicitis

Background There is a substantial gap in provision of adequate surgical care in many low- and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially
