Feeling positively connected to other people is a basic human need. If this need is threatened by feeling lonely, people might become more susceptible to conspiracy theories to help make sense of their surroundings. Simultaneously, conspiracy beliefs could lead to loneliness because they can strain existing relationships. Using two pre‐registered l...

Throughout human history, political leaders, oppositional forces, and businesspeople have frequently coordinated in secret for their own benefit and the public’s disadvantage. In these cases, conspiracy theories are capable of accurately describing our environment. However, the vast majority of research today operationalizes conspiracy theories as...

The experience of meaning has been found to be mapped onto spatial proximity whereby coherent—in contrast to incoherent—elements in a set are mentally represented as closer together in physical space. In a series of four experiments, we show that spatial representation of coherence is malleable and can employ other meaningful concrete dimensions of...

This methodological paper uses a new conceptualization of attitudes, the Causal Attitude Network (CAN) model, to investigate populism and nativism. The CAN model conceptualizes attitudes as a complex system of interrelated factors and captures different attitude components' interplay and mutual dependence. Drawing on two previously collected, repre...

Previous research on predictors of populism and nativism has predominantly focused on socio-economic (e.g., education, employment, social status), and socio-cultural explanations (e.g., social identity and social status). In recent years, however, the role of negative emotions has become increasingly important in the study of populism and related c...

Coherence has been found to be metaphorically mapped onto spatial proximity whereby coherent––in contrast to incoherent––elements in a set are mentally represented as closer together in physical space. In a series of 4 experiments, we show that spatial representation of coherence is malleable and can employ other meaningful concrete dimensions of s...

Vaccine scepticism poses a significant global health risk, which has again become clear during the ongoing Covid-19 pandemic. Previous research has identified spirituality as an important contributor to general vaccine scepticism. In the present manuscript, we assessed whether self-identified spirituality similarly contributes to scepticism towards...

Although sometimes used interchangeably, the present review highlights the important differences between generalized worldviews suspecting conspiracy at play (conspiracy mentality) and specific beliefs about the existence of a certain conspiracy (conspiracy theory). In contrast to measures of beliefs in specific conspiracy theories, those of conspi...

Citizens around the world increasingly express support for populism. Here, we apply the reinforcing spirals model to examine whether, and how, social media news use shapes populist attitudes over time. Specifically, we assess if using social media as a news source serves to maintain existing populist attitudes or facilitates a shift in attitudes to...
