Hamburger Anzeiger - Recycled 'zombie' misinformation targets US voters

Americans are deluged with misinformation about political hot-button issues that observers say have the potential to sway voters in the widely anticipated rematch between President Joe Biden and Donald Trump in November.

That includes misinformation that is recycled online despite being repeatedly knocked down by fact-checkers in what seems like a never-ending game of whack-a-mole.

The trend illustrates the ability of long-debunked falsehoods to mutate into viral political discourse on social media platforms, which now offer fewer guardrails as they scale back content moderation.

"This type of misinformation gets repeated so often that it eventually becomes the gospel truth to believers," Mike Rothschild, an expert on conspiracy theories, told AFP.

"The same tropes get recycled over and over and they work because they're always going to appeal to a certain type of person" in a polarized environment, he added.

That includes a surge of false claims -- inspired by record crossings along the US-Mexico border -- that Democrats are recruiting migrants to sway the presidential election in favor of Biden.

Among the key misinformation spreaders is Elon Musk, the owner of X, formerly Twitter, who claimed ahead of primaries in swing states such as Arizona that the government was "importing voters" by welcoming unvetted illegal immigrants.

AFP's fact-checkers debunked the narrative, noting that migrants admitted on a temporary basis undergo background checks and have no direct path to citizenship or voting rights.

But the claim -- which echoes years-old false narratives from Trump and other US conservatives that seek to demonize migrants -- still received renewed traction, amassing hundreds of thousands of posts and comments across platforms.

- 'Lot of popularity' -

Republican politicians have made immigration a top issue in swing states such as New Hampshire, even as political observers say their claims are not always backed up by facts.

Some 43 percent of residents said illegal immigration is a "very serious" or "somewhat serious" issue in the state, according to a recent poll by the University of New Hampshire.

In recent weeks, AFP has also debunked numerous claims that vaccines are harmful or ineffective, a narrative that has surged since the Covid-19 pandemic despite being repeatedly swatted down.

The deluge comes as Robert F. Kennedy Jr, a longtime vaccine skeptic whose nonprofit raised millions of dollars during the pandemic, makes political inroads in some states as a challenger to Biden and Trump

In part due to the spread of recycled falsehoods, the anti-vaccine community "is in a stronger and better place than it was pre-pandemic," said Kolina Koltai, a senior researcher at the digital investigative group Bellingcat.

"RFK is gaining a lot of popularity and running as an independent," she said. "He's a very well-known anti-vaxxer. That's not nothing."

Distrust in the government is one reason why zombie claims continue to spread, analysts say -- a trend exemplified by the staying power of the "Pizzagate" conspiracy theory.

The theory, which falsely linked a pizza restaurant in the US capital to an underground child sex trafficking ring involving high-ranking Democrats, has been thoroughly debunked since 2016.

Yet it later grew into the sprawling QAnon conspiracy movement, which gained popularity ahead of the 2020 election. Social media users, including Musk, have repeatedly revived the unfounded allegations in recent months.

- 'Cognitive bias' -

Sensational claims that prey on people's innate fears are always going to be fodder for misinformation, experts say.

"Debunking such claims has relatively low impact since people and institutions who do the debunking are considered part of the corrupt system or 'establishment' in the eyes of the people who believe" them, Mert Bayar, from the Center for an Informed Public at the University of Washington, told AFP.

Baseless claims that the 2020 election was ridden with fraud and stolen from Trump still resurface online –- despite being thoroughly debunked by fact-checkers, government officials and audits.

Some of the recycled misinformation goes unchallenged as platforms such as X reduce content moderation in a climate of cost-cutting that has gutted trust and safety teams.

Analysts say misinformation purveyors have a financial motive to continue posting, as X's ad revenue-sharing program incentivizes extreme content designed to boost engagement.

Influencers also tend to reinforce their followers' beliefs.

"This can often be attributed to a cognitive bias known as confirmation bias," Bayar said.

"Content creators might have financial incentives or personal reasons for recycling such claims, but many of the people who spread such claims also genuinely believe in them."
