State media outlets spread propaganda disguised as news online, prompting social media platforms to attach state-affiliated media tags to their accounts. Do these tags reduce belief in state media misinformation? Previous studies suggest the tags reduce misperceptions but focus on Russia, and current research does not compare these tags with other interventions.

Search engine audit studies—where researchers query a set of terms in one or more search engines and analyze the results—have long been instrumental in assessing the relative reliability of search engines. However, on alt-tech platforms, users often conduct a different form of search engine audit.

Alternative cancer treatments are associated with earlier time to death when used without evidence-based treatments. Our study suggests alternative cancer clinics providing scientifically unsupported cancer treatments spent an estimated $15,839,504 on Google ads from 2012 to 2023 targeting users in the United States.

We used a modified Delphi method to elicit and synthesize experts’ views on disinformation, misinformation, and malign influence (DMMI). In a three-part process, experts first independently generated a range of effective strategies for combatting DMMI, identified the most impactful barriers to combatting DMMI, and proposed areas for future research.

Social scientists, journalists, and policymakers are increasingly interested in methods to mitigate or reverse the public’s beliefs in conspiracy theories, particularly those associated with negative social consequences, including violence. We contribute to this field of research using an artificial intelligence (AI) intervention that prompts individuals to reflect on the uncertainties in their conspiracy theory beliefs.

The spread of conspiracy theories is expected to have an increasing impact on the vitality of Western democracies and their political culture. Drawing on a 2022 survey from 10 European countries (with n = 20,449), this study uses narratives about immigration and COVID-19 to examine their relation to individual democratic attitudes and preferred forms of political participation.

Recent instances of political violence have prompted concerns over the relationship between conspiracy theory beliefs and violence. Here, we examine the relationships between beliefs in various conspiracy theories and three operationalizations of violence—support for political violence, self-reported engagement in political violence, and engagement in non-political conflict.

While conspiracy theories have long been tied to race, ethnicity, and religion, understanding this relationship is increasingly important in countries where White identity has become politically charged. This study finds that those high in White consciousness are more likely to 1) engage in generalized conspiracy thinking, 2) endorse the racist “great replacement” conspiracy theory, and 3) move from generalized conspiracy thinking to endorsing specific, non-racial conspiracy theories.

Several existing media literacy games aim to increase resilience to misinformation. However, they lack variety in their approaches. The vast majority focus on assessing information accuracy, with limited exploration of socio-emotional influences of misinformation adoption. Misinformation correction and educational games have explored how narrative persuasion influences personal beliefs, as identification with certain narratives can frame the interpretation of information.

While understanding how social media algorithms operate is essential to protect oneself from misinformation, such understanding is often unevenly distributed. This study explores the algorithmic knowledge gap both within and between countries, using national surveys in the United States (N = 1,415), the United Kingdom (N = 1,435), South Korea (N = 1,798), and Mexico (N = 784).
