Social corrections act as a double-edged sword by reducing the perceived accuracy of false and real news in the UK, Germany, and Italy.

Corrective or refutational posts from ordinary users on social media have the potential to improve the online information ecosystem. While initial evidence of these social corrections is promising, a better understanding of the effects across different topics, formats, and audiences is needed. In three pre-registered experiments (N = 1944 UK, N = 2467 Italy, N = 2210 Germany) where respondents completed a social media post assessment task with false and true news posts on various topics (e.

When experts matter: Variations in consensus messaging for vaccine and genetically modified organism safety.

Does consensus messaging about contested science issues influence perceptions of consensus and/or personal beliefs? This question remains open, particularly for topics other than climate change and samples outside the United States. In a Spanish national sample (N = 5087), we use preregistered survey experiments to examine differential efficacy of variations in consensus messaging for vaccines and genetically modified organisms. We find that no variation of consensus messaging influences vaccine beliefs.

Correlates of support for international vaccine solidarity during the COVID-19 pandemic: Cross-sectional survey evidence from Germany.

During the COVID-19 pandemic, many residents of high-income countries (HICs) were eligible for COVID-19 vaccine boosters, while many residents of lower-income countries (LICs) had not yet received a first dose. HICs made some efforts to contribute to COVID-19 vaccination efforts in LICs, but these efforts were limited in scale. A new literature discusses the normative importance of an international redistribution of vaccines.

Vaccine attributes and vaccine uptake in Hungary: evidence from a conjoint experiment.

Background: In an ongoing public health crisis, the question of why some people are unwilling to take vaccines with particular attributes is an especially pertinent one, since low rates of vaccination mean that it will take longer for many nations to exit the coronavirus disease 2019 (COVID-19) pandemic.

Methods: In this article, we conduct a pre-registered conjoint experiment in Hungary (N = 2512), where respondents were asked about their attitudes towards hypothetical COVID-19 vaccines whose characteristics varied across a number of attributes.

Results: Results indicate that vaccine attributes matter for the likelihood of uptake when it comes to the prevalence of severe side effects, efficacy and country of origin.

Partisanship and anti-elite worldviews as correlates of science and health beliefs in the multi-party system of Spain.

In a national sample of 5087 Spaniards, we examine the prevalence of 10 specific misperceptions over five separate science and health domains (climate change, 5G technology, genetically modified foods, vaccines, and homeopathy). We find that misperceptions about genetically modified foods and general health risks of 5G technology are particularly widespread. While we find that partisan affiliation is not strongly associated with any of the misperceptions aside from climate change, we find that two distinct dimensions of an anti-elite worldview-anti-expert and conspiratorial mindsets-are better overall predictors of having science and health misperceptions in the Spanish context.
