Psychological inoculation interventions, which seek to pre-emptively build resistance against unwanted persuasion attempts, have shown promise in reducing susceptibility to misinformation. However, as many people receive news from popular, mainstream ingroup sources (e.g., a left-wing person consuming left-wing media) which may host misleading or false content, and as ingroup sources may be more persuasive, the impact of source effects on inoculation interventions demands attention.

While algorithms and crowdsourcing have been increasingly used to debunk or label misinformation on social media, such tasks might be most effective when performed by professional fact checkers or journalists. Drawing on a national survey (N = 1,003), we found that U.S. adults evaluated fact-checking labels created by professional fact checkers as more effective than labels by algorithms and other users. News

Bolsonaro’s supporters used social media to spread content during key events related to the Brasília attack. An unprecedented analysis of more than 15,000 public WhatsApp groups showed that these political actors tried to manufacture consensus in preparation for and after the attack. A cross-platform time series analysis showed that the spread of content on Twitter predicted the spread of content on WhatsApp.

Statements of fact can be proved or disproved with objective evidence, whereas statements of opinion depend on personal values and preferences. Distinguishing between these types of statements contributes to information competence. Conversely, failure at fact-opinion differentiation potentially brings resistance to corrections of misinformation and susceptibility to manipulation.
