Especially during the Covid-19 pandemic, it has become evident that conspiracy beliefs are not just a harmless phenomenon but can actually pose a challenge to social cohesion. This paper hypothesizes that tolerance for ambiguity—the ability to deal with ambiguous stimuli and situations—plays an important role in the emergence of Covid-19 conspiracy beliefs. Theoretically, the connection between tolerance for ambiguity and the emergence of conspiracy beliefs can be understood as an epistemic motivation—a desire for understanding, accuracy, and subjective certainty. Empirically, few studies have examined this relationship, and those that have found only small negative associations. However, these assessments were conducted using unreliable scales for measuring tolerance for ambiguity and neglected the concept of right-wing authoritarianism, which is associated with tolerance for ambiguity and can become salient during times of crisis, such as a pandemic. To reexamine this relationship, a survey instrument for tolerance for ambiguity, recently validated for the German-language context, was applied. The data for this study were collected via an online panel surveyed between November 2020 and June 2021. After identifying confounding variables using directed acyclic graphs (DAGs), random-effects panel models are computed using data from two waves (<i>n</i> = 3819 observations, <i>N</i> = 2244 persons). To test the mediation assumption regarding right-wing authoritarianism, structural equation modeling (SEM) was applied to data from the second wave. Results show that tolerance for ambiguity has no significant direct impact on Covid-19 conspiracy beliefs, but an indirect effect via right-wing authoritarianism.</p>","PeriodicalId":48404,"journal":{"name":"Journal of Applied Social Psychology","volume":"55 6","pages":"429-441"},"PeriodicalIF":2.2,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jasp.13098","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144190971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, we conducted a large-scale analysis over the last 28 years (since the Bosman ruling in 1995) of how the exogenous variable, players' social group membership (domestic vs. foreign players), predicts recognition of “player of the season” awards across all professional European soccer leagues. On the basis of social identity theorizing, we argued shared social identity provides a frame of reference from which to perceive and evaluate performance and so hypothesized that foreign players would need to exhibit superior performance than their domestic counterparts for their performance to be recognized with an award. Supporting this hypothesis, results show that foreign players whose performance was recognized in best player awards scored significantly more goals in a season than domestic award winners. The same pattern is evident for goal-per-game ratio, with foreign award winners outperforming their domestic counterparts. Finally, there is evidence that this pattern is moderated by the status of the league such that this differentiation was more pronounced in high-status leagues, indexed by associations' UEFA coefficient.

To test this assumption, we focus on the belief in a norm-consistent (i.e., popular and plausible) climate policy conspiracy theory alleging that powerful groups (i.e., politicians and the business sector) act without public oversight, leading to climate policies that suit their interests but are harmful to the public. Across three studies—one using a quota-based German sample and two preregistered replications (<i>N</i><sub>total</sub> = 1257)—we investigate how the belief in such a theory relates to the endorsement of non-normative collective action, and test whether this relationship also emerges for the belief in a norm-inconsistent (i.e., implausible and unpopular) climate policy conspiracy theory suggesting a similar social reality (Study 3). Our data show that beliefs in both norm-consistent and norm-inconsistent climate policy conspiracy theories correlate positively with support for non-normative collective action, while only the belief in a norm-consistent climate policy conspiracy theory was related to normative collective action.
