US podcast misinformation goes largely unchecked

Unlike social media platforms, podcasts offer little or no opportunity for listeners to comment or push back on misinformation. This 'makes it easier for false, misleading, or unsubstantiated content to spread with little oversight,' Brookings researchers said in their February report. — AFP

WASHINGTON: Rob Lever Misinformation about everything from election fraud to Covid-19 vaccines is reaching millions of Americans through a popular but opaque medium: podcasts.

Many podcasts – on-demand audio programs which users can listen to on smartphones – bluntly promote false and unproven claims.

The Brookings Institution found War Room from former Donald Trump aide Steve Bannon has aired the most false statements, amassing more than 135 million downloads while promoting allegations of vote rigging in the 2020 US election.

Commentator Joe Rogan, whose podcast is the most popular on Spotify, has also used his platform to push unproven Covid-19 treatments.

Analysts say people seek out the shows that reaffirm their own beliefs. But the intimate, conversational format also helps enable the spread of rampant misinformation.

"There's something inherent to the relationship between a host and the audience that lends this level of credibility, this level of trust," Valerie Wirtschafter, a senior data analyst who led the Brookings research, told AFP.

"And the challenge, of course, is that anybody can be a podcaster, anybody can get a microphone and start talking about whatever they want."

Wirtschafter's team analysed 36,000 episodes and found 70% of the most popular US podcasts had shared at least one claim debunked by fact-checkers. Many cast doubt on the 2020 election or the coronavirus pandemic.

Unlike social media platforms, podcasts offer little or no opportunity for listeners to comment or push back on misinformation. This "makes it easier for false, misleading, or unsubstantiated content to spread with little oversight," Brookings researchers said in their February report.

Rogan took down an episode in January after he discussed a fake tweet about Covid-19 vaccines that was falsely attributed to a Florida doctor.

But such a move is rare - and Wirtschafter said moderation is "really complicated" for technology companies.

High listener trust

A Pew Research Center study published in April found about half of Americans listen to podcasts - and 87% say they expect the information to be accurate, representing a higher level of trust than other media.

"The relationship with the host is different," said Sylvia Chan-Olmsted, director of media consumer research at the University of Florida.

"It's like having a one-on-one conversation; you feel this person is talking to you," she told AFP. "People trust it more, and that's why it's more impactful."

Another podcast cited by Brookings is one of Apple's top news commentary programs from conservative activist Charlie Kirk, who has falsely claimed athletes are dying from Covid-19 vaccines and that election officials in Arizona manipulated 2020 results.

Rogan, Bannon and Kirk did not respond to requests for comment. Bannon told The New York Times he considered his inclusion in the report a "badge of honor" and that what others label misinformation, he calls "truth."

'Human intelligence' required

Responding to podcast misinformation is challenging because it is a decentralised, primarily audio-based ecosystem on multiple platforms with different moderation rules.

Spotify, for example, has a policy banning "dangerous" content but also seeks to "respect creator expression." The company stood by Rogan in 2022 when he was accused of spreading coronavirus misinformation.

NewsGuard, a firm that rates the credibility of websites, announced in May it would begin evaluating the trustworthiness of popular podcasts.

NewsGuard said it will release the ratings for some 200 podcasts in 2024, giving more transparency to listeners and enabling advertisers to avoid podcasts featuring misinformation or content at odds with their brand.

Editorial Director Eric Effron said rating podcasts is "more challenging" than other content because of the audio format, which requires time to listen and to examine transcripts.

"This takes a tremendous investment because we use human intelligence," Effron said.

Responsibility for countering podcast misinformation is murky, with some pointing to the hosting platforms or recommendation algorithms from tech giants like Apple, Google and Facebook.

Wirtschafter, the Brookings analyst, said governments, podcast hosts and listeners can all work to improve information quality.

"Taking things down is maybe not the best solution," she said. "But adding more context, providing a richer environment so that people actually can explore evidence or have conversations I think would be extremely useful." – AFP
