A prosocial fake news intervention with durable effects

International audienceAbstract The present online intervention promoted family-based prosocial values—in terms of helping family members—among young adults to build resistance against fake news. This preregistered randomized controlled trial study is among the first psychological fake news interventions in Eastern Europe, where the free press is weak and state-sponsored misinformation runs riot in mainstream media. In this intervention, participants were endowed with an expert role and requested to write a letter to their digitally less competent relatives explaining six strategies that help fake news recognition. Compared to the active control group there was an immediate effect ( d = 0.32) that persisted until the follow-up four weeks later ( d = 0.22) on fake news accuracy ratings of the young, advice-giving participants. The intervention also reduced the bullshit receptivity of participants both immediately after the intervention and in the long run. The present work demonstrates the power of using relevant social bonds for motivating behavior change among Eastern European participants. Our prosocial approach with its robust grounding in human psychology might complement prior interventions in the fight against misinformation

Conspiracy Mentality and Political Orientation across 26 countries

People differ in their general tendency to endorse conspiracy theories (i.e., conspiracy mentality). Previous research yielded inconsistent findings on the relationship between conspiracy mentality and political orientation, showing a greater conspiracy mentality either among the political right (a linear relation), or among both the left and right extremes (a curvilinear relation). We revisited this relationship across two studies spanning 26 countries (combined N=104,253) and found overall evidence for both linear and quadratic relations, even though small and heterogeneous across countries. We also observed stronger support for conspiracy mentality among voters of opposition parties (i.e., those deprived of political control). Nonetheless, the quadratic effect of political orientation remained significant when adjusting for political control deprivation. We conclude that conspiracy mentality is associated with extreme left- and especially extreme right-wing beliefs, and that this non-linear relation may be strengthened by, but is not reducible to, deprivation of political control

Investigating the Links Between Cultural Values and Belief in Conspiracy Theories: the Key Roles of Collectivism and Masculinity

Research suggests that belief in conspiracy theories (CT) stems from basic psychological mechanisms and is linked to other belief systems (e.g., religious beliefs). While previous research has extensively examined individual and contextual variables associated with CT beliefs, it has not yet investigated the role of culture. In the current research, we tested, based on a situated cultural cognition perspective, the extent to which culture predicts CT beliefs. Using Hofstede's model of cultural values, three nation‐level analyses of data from 25, 19, and 18 countries using different measures of CT beliefs (Study 1, N = 5323; Study 2a, N = 12,255; Study 2b, N = 30,994) revealed positive associations between masculinity, collectivism, and CT beliefs. A cross‐sectional study among U.S. citizens (Study 3, N = 350), using individual‐level measures of Hofstede's values, replicated these findings. A meta‐analysis of correlations across studies corroborated the presence of positive links between CT beliefs, collectivism, r = .31, 95% CI = [.15; .47], and masculinity, r = .39, 95% CI = [.18; .59]. Our results suggest that in addition to individual differences and contextual variables, cultural factors also play an important role in shaping CT beliefs
