When Carl Bergstrom labored on plans to arrange the United States for a hypothetical pandemic, within the early 2000s, he and his colleagues had been anxious vaccines may not get to those that wanted them most. “We thought the problem would be to keep people from putting up barricades and stopping the truck and taking all the vaccines off it, giving them to each other,” he recollects.
When COVID-19 arrived, issues performed out fairly in another way. One-quarter of U.S. adults stay unvaccinated in opposition to a virus that has killed greater than 1 million Americans. “Our ability to convince people that this was a vaccine that was going to save a lot of lives and that everyone needed to take was much, much worse than most of us imagined,” Bergstrom says.
He is satisfied this catastrophic failure may be traced to social media networks and their energy to unfold false data—on this case about vaccines—far and quick. “Bullshit” is Bergstrom’s umbrella time period for the falsehoods that propagate on-line—each misinformation, which is unfold inadvertently, and disinformation, designed to unfold falsehoods intentionally.
An evolutionary biologist on the University of Washington (UW), Seattle, Bergstrom has studied the evolution of cooperation and communication in animals, influenza pandemics, and one of the best methods to rank scientific journals. But over the previous 5 years, he has turn into increasingly more keen on how “bullshit” spreads by means of our data ecosystem. He began combating it earlier than COVID-19 emerged—by means of a well-liked e book, a course he offers at UW’s Center for an Informed Public, and, satirically, a vigorous presence on social media—however the pandemic underscored how persuasive and highly effective misinformation is, he says.
“Misinformation has reached crisis proportions,” Bergstrom and his UW colleague Jevin West wrote in a 2021 paper within the Proceedings of the National Academy of Sciences (PNAS). “It poses a risk to international peace, interferes with democratic decision-making, endangers the well-being of the planet, and threatens public health.” In one other PNAS paper, Bergstrom and others issued a name to arms for researchers to review misinformation and discover ways to cease it.
That analysis discipline is now taking off. “You have scholars from so many different disciplines coming together around this common theme”—together with biology, physics, sociology, and psychology—says Philipp Lorenz-Spreen, a physicist who research social media networks on the Max Planck Institute for Human Development.
But the inflow has but to coalesce right into a coherent discipline, says Michael Bang Petersen, a political scientist at Aarhus University. “It’s still spread out in different disciplines and we are not really talking that much together.” There’s additionally disagreement about how finest to review the phenomenon, and the way vital its results are. “The field is really in its infancy,” Lorenz-Spreen says.
Bergstrom grew up in Michigan, however as a toddler twice spent nearly a 12 months in Australia, the place his father, an economist, was on a sabbatical. “That’s where I fell in love with birds,” he says. In his bed room he had a poster of all of the parrots of Australia: “It’s like you handed an 8-year-old a bunch of crayons and a bunch of outlines of parrots and just said, ‘Make them pretty.’” Corvids are his favourite birds due to their cognitive skills. On Twitter, his avatar is a crow.

As a biology scholar at Stanford University, Bergstrom grew fascinated by communication—an evolutionary puzzle due to the potential for deception. “If I listen to you, I give you a handle over my behavior,” Bergstrom says. “I might do the things you want, even if they’re not in my interest.” In his Ph.D. thesis, he tackled the query of how communication can keep helpful when there may be a lot to be gained from misusing it.
In nature, he concluded the reply is usually that lies are pricey. Begging for meals makes child birds susceptible, for instance, so that they have an incentive to do it solely when needed. “If you’re just a defenseless ball of meat sitting in a nest and can’t go anywhere, yelling at the top of your lungs is amazingly stupid,” Bergstrom says. “If they’re not really hungry, they’ll just shut up.” On social media, such repercussions barely exist, he says: Liars have little incentive to close up.
In the early 2000s, whereas a postdoc within the lab of inhabitants biologist Bruce Levin at Emory University, Bergstrom awoke to the specter of infectious illness. He collaborated with a fellow postdoc, Marc Lipsitch—now an epidemiologist on the Harvard T.H. Chan School of Public Health—on papers about pandemic preparedness. Then he delved into community principle, which goals to mathematically describe the properties of networks, together with people who unfold illness. “It appealed to multiple aspects of my intellectual interests,” he says.
Network principle in flip led Bergstrom to the unfold of data. Together with Martin Rosvall, a physicist at Umeå University, he discovered a method to make use of quotation knowledge to create “maps” of the scientific enterprise that confirmed, for instance, how fields cluster and which scientists are most influential. “The algorithms we came up with turned out to work much, much better than I expected,” Bergstrom says. “I still don’t really understand why they are so good.”
Bergstrom’s path by means of totally different disciplines is a testomony to his curiosity and creativity, West says: “You’d be hard-pressed to find someone that really has moved around in such disparate fields and had impacts in all these different areas.”
Around 2017, Bergstrom’s pursuits began to coalesce across the matter of misinformation. The debate about Russian misinformation and the position it performed within the 2016 election of Donald Trump as U.S. president, and an inspiring 2017 assembly about misinformation organized by biologist Joe Bak-Coleman, then at Princeton University, made him notice “this is actually a huge problem and one that’s going to take all these different approaches to deal with it, many of which I personally found very interesting,” he says.
Bergstrom sees social media, like many different issues in life, by means of an evolutionary lens. The common platforms exploit humanity’s want for social validation and fixed chatter, a product of our evolution, he says. He compares it to our yearning for sugar, which was helpful in an atmosphere the place sweetness was uncommon and signaled nutritious meals, however could make us sick in a world the place sugar is in every single place. Facebook exploits people’ thirst for contact, in his view, like a Coca-Cola for the thoughts, permitting individuals to attach with others in bigger numbers throughout a single day than they could have over a lifetime in humanity’s previous.
And whereas Coca-Cola can’t tweak its system on a weekly foundation, social media platforms can always change their algorithms and check out new methods to maintain us engaged. “The social media companies are able to run the largest scale psychological experiments in history by many orders of magnitude, and they’re running them in real time on all of us,” Bergstrom says.

Often, engagement comes from crass battle: “In a schoolyard people cluster around fights, and the same thing happens on Twitter,” he says. Zeynep Tufekci, a sociologist at Columbia University, agrees. “Social connection is ingroup/outgroup,” Tufekci says. That promotes polarization and tribalism in addition to exaggeration and misinformation, she says.
Online networks additionally undermine conventional guidelines of thumb about communication. Before the arrival of the web, for instance, listening to the identical data from a number of individuals made it extra reliable. “In the physical world, it would be almost impossible to meet anyone else who thinks the world is flat,” Stephan Lewandowsky, a psychologist on the University of Bristol, wrote in an electronic mail. “But online, I can connect with the other .000001% of people who hold that belief, and may gather the (false) impression that it is widely shared.”
Social media corporations have little incentive to alter their practices as a result of they earn cash promoting advertisements. “The network structures along which we share information have changed radically in the last 20 years, and they’ve changed without any kind of stewardship,” Bergstrom says. “They’ve changed basically just to help some tech startups sell ads.”
Seeing the issue doesn’t imply he’s resistant to it. Bergstrom admits generally waking up at 4 a.m. and checking his Twitter mentions. “That’s the stupidest thing I could possibly do. Because an hour and a half later, I’m pissed off and can’t sleep,” he says. “It works on all of us, even those of us who know what they’re doing.”
In a perspective revealed in PNAS final 12 months, Bergstrom and 16 different scientists from varied fields argued that the examine of how the data ecosystem influences human collective habits wanted to turn into a “crisis discipline,” very like local weather science, that would additionally recommend methods to deal with the problem. “That paper was just pointing out that the building is on fire,” says Bak-Coleman, the lead creator, who’s now additionally at UW’s Center for the Informed Public. The downside is we don’t know how you can quench the fireplace, he says.
One key downside is that the best way data spreads on social media is decided by the platforms’ proprietary algorithms, which scientists haven’t been in a position to examine. “Even if there was a crisis discipline like Carl wants it, we simply do not have the data,” says Dietram Scheufele of the University of Wisconsin, Madison, who research science communication. “The only way in which we can create that discipline is by policymakers forcing tech companies to provide data access,” Petersen provides.
Researchers have tried to grasp the move of mis- and disinformation in different methods, however the outcomes are sometimes not clear-cut. Last 12 months, a report by the Center for Countering Digital Hate claimed that simply 12 individuals—which it dubbed the “disinformation dozen”—had been the supply of 73% of misinformation about COVID-19 on Facebook. Banning these “superspreaders” might scale back the quantity of misinformation considerably, the authors urged. But Meta, Facebook’s guardian firm, pushed again in opposition to what it referred to as “a faulty narrative” in a weblog submit. The report was based mostly on simply 483 items of content material from solely 30 teams and “in no way representative of the hundreds of millions of posts that people have shared about COVID-19 vaccines in the past months on Facebook,” Meta stated.
The social media corporations are in a position to run the biggest scale psychological experiments in historical past by many orders of magnitude, they usually’re working them in actual time on all of us.

In 2018, researchers from the Massachusetts Institute of Technology’s Media Lab revealed a examine in Science displaying false information spreads “farther, faster, deeper, and more broadly than the truth.” The motive is that folks like novelty, and false tales are more likely to be extra novel, the authors urged. If true, this may permit false information to be recognized mechanically, merely by means of the best way it spreads.
But a reanalysis of the information revealed late final 12 months suggests the image is extra difficult. The Science paper used knowledge on misinformation that had been fact-checked by impartial organizations equivalent to Snopes, which meant it was biased towards misinformation that had already unfold large sufficient to advantage that type of consideration. When researchers factored on this bias, the distinction between the velocity and attain of false information and true information disappeared.
Bak-Coleman, who has studied how faculties of fish suppress false alarms from fish within the periphery of the swarm, believes the density of connections on social media make it tougher to filter out dangerous data. Bergstrom agrees. “If we actually cared about resisting disinformation, Twitter and Facebook might be better off if they said, ‘Look, you can have 300 friends and that’s it,’” he says.
But that, too, wants examine, he says, as do strategic questions: “What would agents do if they wanted to try to inject misinformation into a network? Where would they want to be? And then the flip side: How do you try to counter that?”
To make progress, some researchers say, the budding discipline must focus much less on the community’s properties and extra on its human nodes. Like viruses, misinformation wants individuals to unfold, Tufekci says. “So what you want to really do is study the people end of it,” together with individuals’s causes for clicking Like or Retweet, and whether or not misinformation adjustments their habits and beliefs.
That’s additionally troublesome to review, nevertheless. At UW’s Center for an Informed Public, billions of on-line conversations are captured yearly. If a sure piece of misinformation is recognized, “you can go about measuring how it’s amplified, how fast it grows, who’s amplifying it,” says West, who directs the middle. “But it is very difficult to see whether that translates into behavior, and not just behavior, but beliefs.”
A overview of 45 research on misinformation about COVID-19 vaccines, not too long ago revealed as a preprint by researchers in Norway, concluded that—though misinformation was rampant—there have been few high-quality research of its results. “There is a need for more robust designs to become more certain regarding the actual effect of social media misinformation on vaccine hesitancy,” the authors concluded.
Scientists have tried to review the problem by isolating a really small a part of the issue. A latest paper in Nature Human Behaviour, for instance, reported the outcomes of an experiment carried out in September 2020, earlier than COVID-19 vaccines grew to become accessible. Researchers requested 4000 individuals in each the United Kingdom and the United States whether or not they deliberate to get vaccinated, uncovered them to both information or false details about the vaccines in growth, then measured their intent once more. In each international locations, publicity to misinformation led to a decline of six proportion factors within the share of individuals saying they might “definitely” settle for a vaccine.
Tufekci has little doubt social media has a significant impression on society: “Just look around. It’s a complete shift in how the information ecology works at a social level. How can you not expect it to have an impact?” But small-scale lab research merely can’t correctly measure the issue, she says. “An ecological shift of this nature doesn’t lend itself to that kind of study.” People in the actual world are seemingly uncovered to not one piece of misinformation, however to lots of it over time, usually coming to them by means of pals, household, or different individuals they belief. And on-line misinformation cascades by means of the data ecosystem, pushing extra conventional media to unfold it as properly. “Fox News is kind of competing with that stuff on Facebook,” Tufekci says. “Fox News doesn’t operate in a vacuum.”
We within the infectious illness epidemiology world spent a long time getting ready for a disaster like this, however had been by no means imagining that we might be combating on two fronts, the virus on one and this kind of hyper-partisan disinformation on the opposite.

On Twitter, Carl Bergstrom has battled in opposition to—and mirrored on—the rise of disinformation.
But Scheufele isn’t so certain misinformation has a huge impact. “There is a correlation of course between all this misinformation and the decision by so many people not to get vaccinated, but correlation does not mean causation,” he says. He believes individuals select data to evolve to their world view, not the opposite method round. In his view, misinformation is a symptom, however the actual illness is polarization and a political system and societal local weather that rewards it. Given the deep political polarization within the United States and Trump’s “unusual” presidency, the pandemic “was always going to be a shitshow” there, Scheufele says.
A latest overview in Nature, nevertheless, argued that folks don’t fall for misinformation due to polarization. The authors cited research suggesting true data is extra more likely to be believed than false data, even when it doesn’t align with one’s political opinions. “Politics does not trump truth,” they concluded. The actual downside is individuals sharing data with little consideration as to if it’s true, the authors wrote. “Rather than being bamboozled by partisanship, people often fail to discern truth from fiction because they fail to stop and reflect about the accuracy of what they see on social media.”
Reining in such inconsiderate sharing is the aim of two approaches to tackling misinformation. One, identified within the discipline as “nudging,” contains something from flagging suspicious data—for instance as a result of it’s based mostly on few or nameless sources—to creating it tougher to share one thing. A platform may drive customers to repeat and paste materials earlier than sharing it, or put a restrict on how usually a submit may be reshared. “It’s being shown again and again that it has some benefits when you give people a little time to think about their decision to share something,” Lorenz-Spreen says.
The different method, “boostering,” is designed to enhance customers’ important expertise. This contains “prebunking”—educating individuals how you can spot misinformation—and “lateral reading,” verifying new data while you’re studying it by searching for outdoors data. Those expertise are what Bergstrom has tried to show in a course he taught with West and of their e book, Calling Bullshit: The Art of Skepticism in a Data-Driven World.
When the pandemic began in early 2020, Bergstrom initially thought it might be an important alternative to review the unfold of misinformation, drawing on his background in community principle. “I thought when this has all gone away in March, then I can go through these data sets and figure out what were the spread patterns that we were seeing.” But the pandemic didn’t go away and Bergstrom was sucked into the sensible work of explaining the science and calling out misinformation. He does so primarily in lengthy threads on Twitter, the place he now has greater than 150,000 followers.
In early 2020, for instance, he took on Eric Feigl-Ding, a dietary epidemiologist then at Harvard Medical School who amassed an enormous following with what many scientists felt had been alarmist tweets. When Feigl-Ding tweeted a couple of preprint claiming that SARS-CoV-2 contained sequences from HIV and was seemingly engineered, Bergstrom referred to as him an “alarmist attention-seeker.” (The preprint was withdrawn inside days.)
But the spat confirmed that defining misinformation is troublesome. Feigl-Ding rang the alarm many instances—he’s “very, very concerned” about each new variant, Bergstrom says, and “will tweet about how it’s gonna come kill us all”—however turned out to be proper on some issues. “It’s misinformation if you present these things as certainties and don’t adequately reflect the degree of uncertainty that we have,” Bergstrom says.
Feigl-Ding says utilizing Twitter early within the pandemic was “a big learning curve” for many scientists and that Bergstrom and he “have long made amends and got along well since mid 2020.” Indeed, Bergstrom worries that his tone stoked pointless division and helped unfold the sense that scientists are simply combating over their egos. “The overall lesson, whether it’s dealing with Eric or others, is that I would have done better to be a bit drier, a bit more dispassionate.”
Bergstrom realizes his battle in opposition to misinformation is a Sisyphean process. He likes to cite Brandolini’s regulation, which says “the amount of energy needed to refute bullshit is an order of magnitude larger than is needed to produce it.” Tufekci concurs. “I like Carl’s stuff. I benefit from following him and I’m sure the people who follow him benefit from following him,” she says. “But the societal solution is not to need Carl.”
