Scrolling through your Twitter feed, it may not be obvious when you come upon a bot account — something that is more likely to occur in the era of COVID-19. Carnegie Mellon University researchers have discovered that much of the discussion around the pandemic and stay-at-home orders is being fueled by misinformation campaigns that use convincing bots.
To analyze bot activity around the pandemic, CMU researchers since January have collected more than 200 million tweets discussing coronavirus or COVID-19. Of the top 50 influential retweeters, 82% are bots, they found. Of the top 1,000 retweeters, 62% are bots. […]
“We’re seeing up to two times as much bot activity as we’d predicted based on previous natural disasters, crises and elections,” said Kathleen Carley, a professor in the School of Computer Science’s Institute for Software Research and director of the Center for Computational Analysis of Social and Organizational Systems (CASOS) and Center for Informed Democracy & Social - Cybersecurity (IDeaS.) […]
Carley’s research team uses multiple methods to determine who is or isn’t a bot. Artificial intelligence processes account information and looks at things such as the number of followers, frequency of tweeting and an account’s mentions network. […]
More than 100 types of inaccurate COVID-19 stories have been identified, such as those about potential cures. But bots are also dominating conversations about ending stay-at-home orders and “reopening America.”
Many factors of the online discussions about “reopening America” suggest that bot activity is orchestrated. One indicator is the large number of bots, many of which are accounts that were recently created. Accounts that are possibly humans with bot assistants generate 66% of the tweets. Accounts that are definitely bots generate 34% of the tweets.
“When we see a whole bunch of tweets at the same time or back to back, it’s like they’re timed,” Carley said. “We also look for use of the same exact hashtag, or messaging that appears to be copied and pasted from one bot to the next.” […]
A subset of tweets about “reopening America” reference conspiracy theories, such as hospitals being filled with mannequins or the coronavirus being linked to 5G towers.
“Conspiracy theories increase polarization in groups. It’s what many misinformation campaigns aim to do,” Carley said. “People have real concerns about health and the economy, and people are preying on that to create divides.”
Carley said that spreading conspiracy theories leads to more extreme opinions, which can in turn lead to more extreme behavior and less rational thinking.
