There has been a huge upswell of Twitter bot activity since the start of the coronavirus pandemic, amplifying medical disinformation and the push to reopen America.
Kathleen M. Carley and her team at Carnegie Mellon University’s Center for Informed Democracy & Social Cybersecurity have been tracking bots and influence campaigns for a long time. Across US and foreign elections, natural disasters, and other politicized events, the level of bot involvement is normally between 10 and 20%, she says.
But in a new study, the researchers have found that bots may account for between 45 and 60% of Twitter accounts discussing covid-19. Many of those accounts were created in February and have since been spreading and amplifying misinformation, including false medical advice, conspiracy theories about the origin of the virus, and pushes to end stay-at-home orders and reopen America.
They follow well-worn patterns of coordinated influence campaigns, and their strategy is already working: since the beginning of the crisis, the researchers have observed a greater polarization in Twitter discourse around the topic.
A number of factors could account for this surge. The global nature of the pandemic means a larger swath of actors are motivated to capitalize on the crisis as a way to meet their political agendas. Disinformation is also now more coordinated in general, with more firms available for hire to create such influence campaigns.
But it’s not just the volume of accounts that worries Carley, the center’s director. Their patterns of behavior have grown more sophisticated, too. Bots are now often more deeply networked with other accounts, making it easier for them to disseminate their messages widely. They also engage in more strategies to target at-risk groups like immigrants and minorities and help real accounts engaged in hate speech to form online groups.
