Beliefs play a central role in our lives. They lie at the heart of what makes us human, they shape the organization and functioning of our minds, they define the boundaries of our culture, and they guide our motivation and behavior. Given their central importance, researchers across a number of disciplines have studied beliefs, leading to results a...

Misinformation about mRNA vaccination is a barrier in the global fight against the COVID-19 pandemic. Thus, authorities often rely on text-based refutations as a countermeasure. In two experiments ( N = 2,444), text-based refutations effectively reduced the belief in misinformation and immunized participants against the impact of a misleading socia...

Background: Vaccine confidence among health care professionals (HCPs) is a key determinant of vaccination behaviors. We validate a short-form version of the 31-item Pro-VC-Be (Health Professionals Vaccine Confidence and Behaviors) questionnaire that measures HCPs' confidence in and commitment to vaccination. Research design and methods: A cross-...
Article
Full-text available
Although conspiracy theories are only endorsed by a minority, conspiracy theories can nonetheless compromise public health measures to control the COVID-19 pandemic. Individuals who endorse conspiracy theories were less likely to wear masks, comply with social distancing, or get vaccinated. This poses a challenge to public health policy, in particu...

Background Vaccination coverage needs to reach more than 80% to resolve the COVID-19 pandemic, but vaccine hesitancy, fuelled by misinformation, may jeopardize this goal. Unvaccinated older adults are not only at risk of COVID-19 complications but may also be misled by false information. Prebunking, based on inoculation theory, involves ‘forewarnin...
Article
Objectives: The lack of validated instruments assessing vaccine hesitancy/confidence among health care professionals (HCPs) for themselves, and their patients led us to develop and validate the Pro-VC-Be instrument to measure vaccine confidence and other psychosocial determinants of HCPs' vaccination behavior among diverse HCPs in different countr...
Article
We explore the common attributes of political conflicts in which scientific findings have a central role, using the COVID-19 pandemic as a case study, but also drawing on long-standing conflicts over climate change and vaccinations. We analyze situations in which the systematic spread of disinformation or conspiracy theories undermines public trust...
Article
Full-text available
Contact tracing apps have been identified as a promising technology to curb the spread of COVID-19. To be effective, a sufficient number of individuals needs to install the app and to disclose information like a COVID-19 infection to such an app. Yet, usage data demonstrates that a large amount of app users does not disclose a COVID-19 infection to...
Article
Misinformation has been identified as a major contributor to various contentious contemporary events ranging from elections and referenda to the response to the COVID-19 pandemic. Not only can belief in misinformation lead to poor judgements and decision-making, it also exerts a lingering influence on people’s reasoning after it has been corrected...

Trotz aktuell steigender Impfbereitschaft unter den Erstimpfungen ist nicht abzusehen, dass die vom RKI geforderten Impfquoten für die künftige Kontrolle des SARS-CoV-2 Virus mit den bisherigen Maßnahmen zur Steigerung der Impfbereitschaft erreicht werden können (Stand: Ende November, 2021). Daher werden in diesem Artikel drei Typen verpflichtender...

Introduction At least 68% of persons with aphasia (PWA) experience reading difficulties. Even though strategy-based interventions are a promising treatment approach for text level reading comprehension deficits in PWA, empirical evidence for their efficacy remains rare. The primary objective of this study is the analysis of the efficacy of a strate...
Article
Full-text available
In mass media, the positions of science deniers and scientific-consensus advocates are repeatedly presented in a balanced manner. This false balance increases the spread of misin-formation under the guise of objectivity. Weight-of-evidence strategies are an alternative, in which journalists lend weight to each position that is equivalent to the amo...

Governments around the world have implemented measures to manage the transmission of coronavirus disease 2019 (COVID-19). While the majority of these measures are proving effective, they have a high social and economic cost, and response strategies are being adjusted. The World Health Organization (WHO) recommends that communities should have a voi...
Article
Background In Germany, vaccination gaps exist mainly among adolescents and adults. Family physicians (FPs) administer adult vaccines. FPs strongly influence the vaccination behavior and attitudes of their patients, so their own vaccination-related attitudes and behaviors are critical to achieve high vaccination coverage. The aim of this study was t...
Article
Objective: Previous studies have shown that even when a statistical base-rate of vaccine adverse events (VAE) is provided, a small sample of single-case narratives influences vaccination risk perceptions and vaccination intentions, irrespective of various content characteristics. This study investigated whether this narrative bias is moderated by a...

Full-text available
Science deniers question scientific milestones and spread misinformation, contradicting decades of scientific endeavour. Advocates for science need effective rebuttal strategies and are concerned about backfire effects in public debates. We conducted six experiments to assess how to mitigate the influence of a denier on the audience. An internal me...

When people judge risk or the probability of a risky prospect, single case narratives can bias judgments when a statistical base-rate is also provided. In this work we investigate various methodological and procedural factors that may influence this narrative bias. We found that narratives had the strongest effect on a non-numerical risk measure, w...
