Meta founder and CEO Mark Zuckerberg has announced big changes in how the company addresses misinformation across Facebook, Instagram and Threads. Instead of relying on independent third-party factcheckers, Meta will now emulate Elon Musk’s X (formerly Twitter) in using “community notes”. These crowdsourced contributions allow users to flag content they believe is questionable.

Zuckerberg claimed these changes promote “free expression”. But some experts worry he’s bowing to right-wing political pressure, and will effectively allow a deluge of hate speech and lies to spread on Meta platforms.

Research on the group dynamics of social media suggests those experts have a point.

At first glance, community notes might seem democratic, reflecting values of free speech and collective decisions. Crowdsourced systems such as Wikipedia, Metaculus and PredictIt, though imperfect, often succeed at harnessing the wisdom of crowds — where the collective judgement of many can sometimes outperform even experts.

Research shows that diverse groups that pool independent judgements and estimates can be surprisingly effective at discerning the truth. However, wise crowds seldom have to contend with social media algorithms.

Many people rely on platforms such as Facebook for their news, risking exposure to misinformation and biased sources. Relying on social media users to police information accuracy could further polarise platforms and amplify extreme voices.

Two group-based tendencies — our psychological need to sort ourselves and others into groups — are of particular concern: in-group/out-group bias and acrophily (love of extremes).

INGROUP / OUTGROUP BIAS

Humans are biased in how they evaluate information. People are more likely to trust and remember information from their in-group — those who share their identities — while distrusting information from perceived out-groups. This bias leads to echo chambers, where like-minded people reinforce shared beliefs, regardless of accuracy.

It may feel rational to trust family, friends or colleagues over strangers. But in-group sources often hold similar perspectives and experiences, offering little new information. Out-group members, on the other hand, are more likely to provide diverse viewpoints. This diversity is critical to the wisdom of crowds.

But too much disagreement between groups can prevent community fact-checking from even occurring. Many community notes on X (formerly Twitter), such as those related to COVID vaccines, were likely never shown publicly because users disagreed with one another. The benefit of third-party factchecking was to provide an objective outside source, rather than needing widespread agreement from users across a network.

Worse, such systems are vulnerable to manipulation by well organised groups with political agendas. For instance, Chinese nationalists reportedly mounted a campaign to edit Wikipedia entries related to China-Taiwan relations to be more favourable to China.

POLITICAL POLARISATION AND ACROPHILY

Indeed, politics intensifies these dynamics. In the US, political identity increasingly dominates how people define their social groups.

Political groups are motivated to define “the truth” in ways that advantage them and disadvantage their political opponents. It’s easy to see how organised efforts to spread politically motivated lies and discredit inconvenient truths could corrupt the wisdom of crowds in Meta’s community notes.

Social media accelerates this problem through a phenomenon called acrophily, or a preference for the extreme. Research shows that people tend to engage with posts slightly more extreme than their own views.

These increasingly extreme posts are more likely to be negative than positive. Psychologists have known for decades that bad is more engaging than good. We are hardwired to pay more attention to negative experiences and information than positive ones.

On social media, this means negative posts – about violence, disasters and crises – get more attention, often at the expense of more neutral or positive content.

Those who express these extreme, negative views gain status within their groups, attracting more followers and amplifying their influence. Over time, people come to think of these slightly more extreme negative views as normal, slowly moving their own views toward the poles.

A recent study of 2.7 million posts on Facebook and Twitter found that messages containing words such as “hate”, “attack” and “destroy” were shared and liked at higher rates than almost any other content. This suggests that social media isn’t just amplifying extreme views — it’s fostering a culture of out-group hate that undermines the collaboration and trust needed for a system like community notes to work.

THE PATH FORWARD

The combination of negativity bias, in-group/out-group bias and acrophily supercharges one of the greatest challenges of our time: polarisation. Through polarisation, extreme views become normalised, eroding the potential for shared understanding across group divides.

The best solutions, which I examine in my forthcoming book, The Collective Edge, start with diversifying our information sources. First, people need to engage with — and collaborate across — different groups to break down barriers of mistrust. Second, they must seek information from multiple, reliable news and information outlets, not just social media.

However, social media algorithms often work against these solutions, creating echo chambers and trapping people’s attention. For community notes to work, these algorithms would need to prioritise diverse, reliable sources of information.

While community notes could theoretically harness the wisdom of crowds, their success depends on overcoming these psychological vulnerabilities. Perhaps increased awareness of these biases can help us design better systems — or empower users to use community notes to promote dialogue across divides. Only then can platforms move closer to solving the misinformation problem.

Palm Beach, Florida:

US President-elect Donald Trump said Facebook-parent Meta’s abrupt policy shift on content moderation, including ending fact-checking in the United States, was “probably” motivated by his threats against CEO Mark Zuckerberg.

Speaking to reporters at his Mar-a-Lago estate in Florida, Trump expressed satisfaction with Meta’s move, and when asked if he believed it was a response to his threats against Zuckerberg, responded: “Probably, yeah.”

Social media giant Meta on Tuesday slashed its content moderation policies, including ending its US fact-checking program on Facebook and Instagram, in a major shift that conforms with the priorities of incoming president Donald Trump.

“We’re going to get rid of fact-checkers (that) have just been too politically biased and have destroyed more trust than they’ve created, especially in the US,” Meta founder and CEO Mark Zuckerberg said in a post.

Instead, Meta platforms including Facebook and Instagram, “would use community notes similar to X (formerly Twitter), starting in the US,” he added.

Meta’s surprise announcement echoed long-standing complaints made by Trump’s Republican Party and X owner Elon Musk about fact-checking, which many conservatives see as censorship.

They argue that fact-checking programs disproportionately target right-wing voices, which has led to proposed laws in states like Florida and Texas to limit content moderation.

“This is cool,” Musk posted on his X platform after the announcement.

Zuckerberg, in a nod to Trump’s victory, said that “recent elections feel like a cultural tipping point towards, once again, prioritizing speech” over moderation.

The shift came as the 40-year-old tycoon has been making efforts to reconcile with Trump since his election in November, including donating one million dollars to his inauguration fund.

Trump has been a harsh critic of Meta and Zuckerberg for years, accusing the company of bias against him and threatening to retaliate against the tech billionaire once back in office.

Speaking to reporters at his Mar-a-Lago estate in Florida, Trump when asked if he believed the move was a response to his threats against Zuckerberg, responded: “Probably, yeah.”

The Republican was kicked off Facebook following the January 6, 2021, attack on the US Capitol by his supporters, though the company restored his account in early 2023.

ENDING ‘FACEBOOK JAIL’

Zuckerberg, like several other tech leaders, has met with Trump at his Mar-a-Lago resort in Florida ahead of his January 20 inauguration.

Meta has made moves in recent days that are likely to please Trump’s team, such as appointing former Republican official Joel Kaplan to head up public affairs at the company.

He takes over from Nick Clegg, a former British deputy prime minister.

Zuckerberg also named Ultimate Fighting Championship (UFC) head Dana White, a close ally of Trump, to the Meta board.

Kaplan, in a statement Tuesday, insisted the company’s approach to content moderation had “gone too far.”

“Too much harmless content gets censored, too many people find themselves wrongly locked up in ‘Facebook jail,'” he said.

As part of the overhaul, Meta said it will relocate its trust and safety teams from liberal California to more conservative Texas.

“That will help us build trust to do this work in places where there is less concern about the bias of our teams,” Zuckerberg said.

Zuckerberg also took a shot at the European Union “that has an ever increasing number of laws institutionalizing censorship and making it difficult to build anything innovative there.”

The remark referred to new laws in Europe that require Meta and other major platforms to maintain content moderation standards or risk hefty fines.

Zuckerberg said that Meta would “work with President Trump to push back against foreign governments going after American companies to censor more.”

Additionally, Meta announced it would reverse its 2021 policy of reducing political content across its platforms.

COMMUNITY NOTES

News agency AFP currently works in 26 languages with Facebook’s fact-checking program, in which Facebook pays to use fact-checks from around 80 organizations globally on its platform, WhatsApp and Instagram.

In that program, content rated “false” is downgraded in news feeds so fewer people will see it and if someone tries to share that post, they are presented with an article explaining why it is misleading.

Community Notes on X (formerly Twitter) allows users to collaboratively add context to posts in a system that aims to distill reliable information through consensus rather than top-down moderation.

Meta’s move into fact-checking came in the wake of Trump’s shock election in 2016, which critics said was enabled by rampant disinformation on Facebook and interference by foreign actors, including Russia, on the platform.
