Promoting Anti-Rape Attitudes in Young Men Through the Repetition-Induced Truth Effect
The repetition-induced truth effect (RITE) refers to the robust observation that repeated statements are more likely to be believed than new ones. We propose that this mechanism can be used to promote anti-rape attitudes. We conducted three experimental studies (n1 = 103, n2 = 206, n3 = 339) to test whether repetition increases agreement with statements from an anti-rape attitude scale. Participants, all heterosexual men aged 18-25, were presente…
Addressing climate change with behavioral science: A global intervention tournament in 63 countries
Effectively reducing climate change requires marked, global behavior change. However, it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. Here, we tested 11 expert-crowdsourced interventions on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. Across 59,440 participants from 63 countries, the interve…
Selective exposure bias predicts views on diversity over time
Despite growing diversity, many individuals do not support it, posing a challenge to the successful functioning of societies, institutions, and organizations. We investigated the role of the selective exposure bias on diversity beliefs. In a large-scale nationally representative Spanish sample ( N = 2,297), we conducted a time-lagged experiment with two time points 5 months apart in which we offered participants a monetary incentive to (allegedly…
Disliked but Free to Speak: Cognitive Ability Is Related to Supporting Freedom of Speech for Groups Across the Ideological Spectrum
Freedom of speech for all citizens is often considered as a cornerstone of democratic societies. In three studies, we examined the relationship between cognitive ability and support for freedom of speech for a variety of social groups across the ideological spectrum ( N 1 varies between 1,373 and 18,719, N 2 = 298, N 3 = 395). Corroborating our theoretical expectations, although cognitive ability was related to more affective prejudice toward rel…
Bright mind, moral mind? Intelligence is unrelated to consequentialist moral judgment in sacrificial moral dilemmas
Toward an Integrated Cognition Perspective on Ethnic Prejudice: An Investigation Into the Role of Intelligence and Need for Cognitive Closure
Both ability and motivation aspects of cognition have been shown to relate to ethnic prejudice. In line with recent theorizing, the present study advances an integrated cognition perspective on ethnic prejudice by examining the interplay between cognitive ability (measured with the Kaufman Adolescent and Adult Intelligence Test) and cognitive motivation (measured with the Need for Cognitive Closure [NFC] Scale) in a Belgian, heterogeneous adult s…
The relationship between emotional abilities and right-wing and prejudiced attitudes
Previous research revealed that cognitive abilities are negatively related to right-wing and prejudiced attitudes. No study has, however, investigated if emotional abilities also show such a relationship, although this can be expected based on both classic and recent literature. The aim of the present study was 2-fold: (a) to investigate the relationship between emotional abilities and right-wing and prejudiced attitudes, and (b) to pit the effec…
‘Fake news’: Incorrect, but hard to correct. The role of cognitive ability on the impact of false information on social impressions
The present experiment (N = 390) examined how people adjust their judgment after they learn that crucial information on which their initial evaluation was based is incorrect. In line with our expectations, the results showed that people generally do adjust their attitudes, but the degree to which they correct their assessment depends on their cognitive ability. In particular, individuals with lower levels of cognitive ability adjusted their attit…
The Motivated Cognitive Basis of Transphobia: The Roles of Right-Wing Ideologies and Gender Role Beliefs
The Mobilizing Effect of Right‐Wing Ideological Climates: Cross‐Level Interaction Effects on Different Types of Outgroup Attitudes
The present research investigated a multilevel person‐context interactionist framework for the relationship between right‐wing ideologies and prejudice across two large, representative samples (Study 1: European Social Survey: N = 56,752; Study 2: World Values Survey: N = 74,042). Across three different operationalizations of right‐wing ideology, two contextual levels (regional and national) of right‐wing climate, and three types of outgroup atti…
Need for Closure Effects on Affective and Cognitive Responses to Culture Fusion
This research examined how affective and cognitive responses to culture fusion, a specific type of culture mixing that features the blending of different cultures or parts thereof into a new entity, are influenced by individual differences in Need for Closure (NFC). Two studies showed that individuals high (vs. low) in NFC felt less favorable toward culture fusion (i.e., the affective response), both at an abstract level (i.e., society structure …
