Abstract: The Russian influence operations in 2016 and the Russia-Ukraine war have revealed the limitations of siloed, disciplinary analyses of social media. A sufficiently unhealthy information environment is an existential threat to democracy; non-democratic actors understand this, and they are acting to undermine their rivals. The democratization of the task of information curation and verification—a role that the mass democracies of the 20th century assigned to an educated, elite profession—happened vertiginously quickly. This new networked infosphere is only as strong as its weakest links.

Individuals who have very low digital literacy and who lack the tools to understand the information environment (in today’s U.S., the very old) act as weak points in the social information-verification system on social media, enabling the beginning of “credibility cascades” even in the absence of credible information sources. The addition of even a small number of this kind of actor significantly degrades the infosphere—especially when combined with other actors who are actively trying to disrupt the information ecosystem. Post-social media democracy cannot flourish without investing in citizens’ information verification and curation capacities.
