The Covid-19 pandemic has sparked renewed attention to the risks of online misinformation, emphasizing its impact on individuals’ quality life through spread health-related myths and misconceptions. In this study, we analyze 6 years (2016–2021) Italian vaccine debate across diverse social media platforms (Facebook, Instagram, Twitter, YouTube), encompassing all major news sources–both questionable reliable. We first use symbolic transfer entropy analysis production time-series dynamically determine which category sources, or reliable, causally drives agenda vaccines. Then, leveraging deep learning models capable accurately classify vaccine-related content based conveyed stance discussed topic, respectively, evaluate focus various topics by sources promoting opposing views compare resulting user engagement. Our study uncovers misinformation not as a parasite ecosystem that merely opposes perspectives offered mainstream media, but an autonomous force even overwhelming from latter. While pervasiveness is evident in significantly higher engagement compared reliable ones (up 11 times median value), our findings underscore need for consistent thorough pro-vax coverage counter imbalance. This especially important sensitive topics, where risk spreading potentially exacerbating negative attitudes toward vaccines higher. have successfully promoted efficacy, reducing anti-vax impact, gaps safety led highest with content.

Much like a viral contagion, misinformation can spread rapidly from one individual to another. Inoculation theory offers logical basis for developing psychological “vaccine” against misinformation. We discuss the origins of inoculation theory, starting with its roots in 1960s as “vaccine brainwash,” and detail major theoretical practical innovations that research has witnessed over years. Specifically, we review series randomized lab field studies show it is possible preemptively “immunize” people by preexposing them severely weakened doses techniques underlie production along ways on how spot refute them. evidence interventions developed governments social media companies help citizens around world recognize resist unwanted attempts influence mislead. conclude discussion important open questions about effectiveness interventions.

Some strategies, such as scare tactics, appear be ineffective may increase endorsement. Communicating with certainty, rather than acknowledging uncertainty efficacy risks, found backfire. Promising approaches include weight-of-evidence scientific consensus related myths, humour incorporating warnings about encountering misinformation.

Here, across four experiments (n = 3,364), we motivated US participants by providing financial incentives for correct responses about the veracity true and false political news headlines. Financial improved accuracy reduced partisan bias judgements headlines 30%, primarily increasing perceived from opposing party (d 0.47). Incentivizing people identify that would liked their allies, however, decreased accuracy.

Abstract Misinformation can have a profound detrimental impact on populations’ wellbeing. In this large UK-based online experiment (n = 2430), we assessed the performance of false tag and inoculation interventions in protecting against different forms misinformation (‘variants’). While previous experiments used perception- or intention-based outcome measures, presented participants with real-life posts social media platform simulation measured their engagement, more ecologically valid approach. Our pre-registered mixed-effects models indicated that both reduced engagement misinformation, but was most effective. However, random differences analysis revealed protection conferred by differed across posts. Moderation immunity provided is robust to variation individuals’ cognitive reflection.
