COVID-19 conspiracy theories emerged almost immediately after the beginning of the pandemic, and the number of believers does not appear to decline. Believing in these theories can negatively affect adherence to safety guidelines and vaccination intentions, potentially endangering the lives of many. Thus, one part in successfully fighting the pandemic is to understand the antecedents and consequences of COVID-19 conspiracy beliefs, which are here presented in a rapid review summarizing research from more than 28 countries. We evaluate the contribution of individual difference variables (demographic variables, personality traits, coping with threat and uncertainty), beliefs, biases, and attitudes (epistemically suspect beliefs, thinking styles and cognitive biases, attitudes towards science), and social factors (group identities, trust in authorities, social media) to COVID-19 conspiracy theories. We discuss the consequences of COVID-19 conspiracy beliefs in regard to safeguarding behaviours (hygiene, distancing, and mask-wearing), self-centred (hoarding) and misguided behaviours (pseudoscientific practices), vaccination intentions, mental health and negative social consequences (e.g., discrimination and violence). Differences between countries as well as various conspiracy theories are considered. Summarising, we suggest that belief in COVID-19 conspiracy theories is boosted by low levels of trust in a context of threat and low levels of comprehensive, accessible information in a context of uncertainty and unknowns. We conclude that research is urgently needed to address potential interventions to (re-)establish trust and provide accessible information about COVID-19.
We present evidence from two studies probing into whether perceived numerical decline in the White population translate into collective existential threat to Whites, leading in turn to defensive reactions. In Study 1, we used correlational data to show whether collective existential threat mediates the relationship between perceptions of White population decline and defensive political reactions (i.e., racial biases and conservatism) among Whites. In Study 2, we replicate the results of Study 1 experimentally manipulating perceptions of White population decline and growth. Our results suggest that Whites’ perceptions of the ingroup’s numerical decline have a unique effect on their racial and political attitudes via heightened feelings of collective existential threat.
The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world.
Using large samples that are nationally diverse or nationally representative (total N ϭ 44,836), this article presents evidence that citizens' prejudice does not usually benefit or undermine politicians who are from a particular demographic group, as many past studies assumed; instead, citizens' prejudice is associated with support for conservative politicians and opposition to liberal politicians, regardless of politicians' demographic background. Study 1a and Study 1b show that, regardless of the race and gender of real politicians, racism and sexism negatively predict support for liberal politicians, and positively predict support for conservative politicians. This overall pattern is experimentally confirmed in Study 2 where participants evaluate a hypothetical politician. Using data collected between 1972 and 2016, Study 3 shows that, historically, the predictive effect of racism and sexism on support for politicians in general is moderated by politicians' perceived ideology. Study 4 addresses a limitation of Study 1-3, and Study 5 extends the results for prejudice to the religious domain (i.e., prejudice toward Muslims). Together, these studies suggest that the way prejudice is related to support for a politician is primarily moderated by the politician's political ideology, not the politician's demographic background. Thus, this article highlights the oftenoverlooked role of politicians' ideology, clarifying theories that explain how citizens' prejudice is translated into their political preferences.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
