About half of the Twitter accounts pushing misinformation about COVID-19 and calling for "reopening America" may be bots, researchers at Carnegie Mellon University said Wednesday. The tweets appear to be aiming to sow division and increase polarization during the pandemic.

"Conspiracy theories increase polarization in groups. It's what many misinformation campaigns aim to do," Kahtleen Carley, a computer science professor, said in a statement about the ongoing research. "People have real concerns about health and the economy, and people are preying on that to create divides."

Since January, the researchers have collected more than 200 million tweets discussing COVID-19 and coronavirus. They found that 82% of the top 50 influential retweets are bots, and 62% of the top 1,000 retweeters are bots, too.

Bots have been spreading more than 100 types of inaccurate COVID-19 stories, such as information about unproven "cures." But they have largely dominated the discussions about "reopening America" and ending stay-at-home orders — issues that have led to real-life protests in states nationwide. Some of the tweets about reopening also spread baseless conspiracy theories

The researchers said 66% of accounts discussing "reopening America" are possibly humans with bot assistants, and about 34% are definitely bots.

She warned that the misinformation "will have a variety of real-world consequences, and play out in things like voting behavior and hostility towards ethnic groups."

Since January, the researchers have collected more than 200 million tweets discussing COVID-19 and coronavirus. They found that 82% of the top 50 influential retweets are bots, and 62% of the top 1,000 retweeters are bots, too.

Bots have been spreading more than 100 types of inaccurate COVID-19 stories, such as information about unproven "cures." But they have largely dominated the discussions about "reopening America" and ending stay-at-home orders — issues that have led to real-life protests in states nationwide. Some of the tweets about reopening also spread baseless conspiracy theories, such as hospitals being filled with mannequins, or a supposed link between coronavirus and 5G towers.

The researchers said 66% of accounts discussing "reopening America" are possibly humans with bot assistants, and about 34% are definitely bots.

Bots can usually be detected in accounts that were recently created and appear to be tweeting copy-and-pasted messages, or putting out a series of tweets that are timed to promote a certain topic.

In addition, "Tweeting more frequently than is humanly possible or appearing to be in one country and then another a few hours later is indicative of a bot," Carley said.

The researchers have also started looking into posts on Facebook, YouTube and Reddit.

Carley said the misinformation campaigns look like "a propaganda machine" and match "the Russian and Chinese playbooks," but the research have not yet determined who is behind the bots. China and Russia have already been detected in spreading misinformation about the pandemic.
