Cognitive dysfunction, and the resulting social behaviours, contribute to major problems, ranging from polarisation spread of conspiracy theories. Most previous studies have explored these problems at a specific scale: individual, group, or societal. This study develops synthesis that links models cognitive failures three scales. First, limits innate drives can lead dysfunctional cognition in individuals. Second, biases effects further influence group behaviour. Third, networks cause cascading increase intensity scale Advances communications information technology, especially Internet AI, exacerbated established by accelerating false beliefs interpretations on an unprecedented scale, become enabler for emergent hitherto only seen smaller scale.

Measuring receptivity to misinformation at scale on a social media platform

Abstract Measuring the impact of online misinformation is challenging. Traditional measures, such as user views or shares on social media, are incomplete because not everyone who exposed to equally likely believe it. To address this issue, we developed a method that combines survey data with observational Twitter probabilistically estimate number users both and specific news story. As proof concept, applied 139 viral articles find although false reaches an audience diverse political views, receptive believing tend have more extreme ideologies. These also encounter earlier than those unlikely This mismatch between overall exposure underscores limitation relying solely interaction measure misinformation, well challenge implementing effective interventions. demonstrate how our approach can challenge, then conducted data-driven simulations common interventions used by media platforms. We these only modestly at reducing among their effectiveness quickly diminishes unless implemented soon after misinformation’s initial spread. Our paper provides precise focusing it, offering insights for mitigation strategies media.

Nudge-based misinformation interventions are effective in information environments with low misinformation prevalence

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: May 20, 2024

Nudge-based misinformation interventions are presented as cheap and effective ways to reduce the spread of online. However, despite online information environments typically containing relatively low volumes misinformation, most studies testing effectiveness nudge present equal proportions true false information. As nudges can be highly context-dependent, it is imperative validate nudge-based in with more realistic misinformation. The current study (N = 1387) assessed a combined accuracy social-norm simulated social-media varying (50%, 20%, 12.5%) relative non-news-based (i.e., "social") intervention was at improving sharing discernment conditions lower providing ecologically valid support for use counter propagation on social media.
