The social function of rationalization: An identity perspective.

In this commentary, we offer an additional function of rationalization. Namely, in certain social contexts, the proximal and ultimate function of beliefs and desires is social inclusion. In such contexts, rationalization often facilitates distortion of rather than approximation to truth. Understanding the role of social identity is not only timely and important, but also critical to fully understand the function(s) of rationalization.

National Narcissism predicts the Belief in and the Dissemination of Conspiracy Theories During the COVID-19 Pandemic: Evidence From 56 Countries.

Conspiracy theories related to coronavirus disease 2019 (COVID-19) have propagated around the globe, leading the World Health Organization to declare the spread of misinformation an "Infodemic." We tested the hypothesis that national narcissism-a belief in the greatness of one's nation that requires external recognition-is associated with the spread of conspiracy theories during the COVID-19 pandemic. In two large-scale national surveys (NTotal = 950) conducted in the United States and the United Kingdom, and secondary analysis of data from 56 countries (N = 50,757), we found a robust, positive relationship between national narcissism and proneness to believe and disseminate conspiracy theories related to COVID-19. Furthermore, belief in COVID-19 conspiracy theories was related to less engagement in health behaviors and less support for public-health policies to combat COVID-19. Our findings illustrate the importance of social identity factors in the spread of conspiracy theories and provide insights into the psychological processes underlying the COVID-19 pandemic.

A Small Price to Pay: National Narcissism Predicts Readiness to Sacrifice In-Group Members to Defend the In-Group's Image.

Collective narcissism is a belief in one's in-group greatness that is underappreciated by others. Across three studies conducted in the context of the coronavirus disease 2019 (COVID-19) pandemic, we found that collective narcissism, measured with respect to the national group, was related to support of policies that protect the national image at the expense of in-group members' health. In Study 1, British national narcissism was related to opposing cooperation with the European Union (EU) on medical equipment. In Study 2, American national narcissism predicted opposition to COVID-19 testing to downplay the number of cases. In Study 3, American national narcissism was related to support for releasing an untested COVID-19 vaccine, to beat other countries to the punch. These relationships were mediated by concern about the country's reputation. Our studies shed light on collective narcissism as a group-based ego-enhancement strategy in which a strong image of the group is prioritized over members' well-being.

How social media shapes polarization.

This article reviews the empirical evidence on the relationship between social media and political polarization. We argue that social media shapes polarization through the following social, cognitive, and technological processes: partisan selection, message content, and platform design and algorithms.

The dark side of social movements: social identity, non-conformity, and the lure of conspiracy theories.

Social change does not always equal social progress-there is a dark side of social movements. We discuss conspiracy theory beliefs - beliefs that a powerful group of people are secretly working towards a malicious goal - as one contributor to destructive social movements. Research has linked conspiracy theory beliefs to anti-democratic attitudes, prejudice and non-normative political behavior. We propose a framework to understand the motivational processes behind conspiracy theories and associated social identities and collective action. We argue that conspiracy theories comprise at least two components - content and qualities-that appeal to people differently based on their motivations. Social identity motives draw people foremost to contents of conspiracy theories while uniqueness motives draw people to qualities of conspiracy theories.
