Misinformation lends itself to social contagion – here’s how to recognize and combat it

In 2019, a rare and shocking event in the Malaysian peninsula town of Ketereh grabbed international headlines. Nearly 40 girls age 12 to 18 from a religious school had been screaming inconsolably, claiming to have seen a “face of pure evil,” complete with images of blood and gore.

Experts believe that the girls suffered what is known as a mass psychogenic illness, a psychological condition that results in physical symptoms and spreads socially – much like a virus.

I’m a social and behavioral scientist within the field of public health. I study the ways in which individual behavior is influenced by prevailing social norms and social network processes, across a wide range of behaviors and contexts. Part of my work involves figuring out how to combat the spread of harmful content that can shape our behavior for the worse, such as misinformation.

Mass psychogenic illness is not misinformation, but it gives researchers like me some idea about how misinformation spreads. Social connections establish pathways of influence that can facilitate the spread of germs, mental illness and even behaviors. We can be profoundly influenced by others within our social networks, for better or for worse.

The spreading of social norms

Researchers in my field think of social norms as perceptions of how common and how approved a specific behavior is within a specific network of people who matter to us.

These perceptions may not always reflect reality, such as when people overestimate or underestimate how common their viewpoint is within a group. But they can influence our behavior nonetheless. For many, perception is reality.

Social norms and related behaviors can spread through social networks like a virus can, but with one crucial caveat. Viruses often require just one contact with a potential host to spread, whereas behaviors often require multiple contacts to spread. This phenomenon, known as complex contagion, highlights how socially learned behaviors take time to embed.

Watch the people in this video and see how you react.

Fiction spreads faster than fact

Consider a familiar scenario: the return of baggy jeans to the fashion zeitgeist.

For many millennials like me, you may react to a friend engaging in this resurrected trend by cringing and lightly teasing them. Yet, after seeing them don those denim parachutes on multiple occasions, a brazen thought may emerge: “Hmm, maybe they don’t look that bad. I could probably pull those off.” That’s complex contagion at work.

This dynamic is even more evident on social media. One of my former students expressed this succinctly. She was looking at an Instagram post about Astro Boy Boots – red, oversize boots based on those worn by a 1952 Japanese cartoon character. Her initial skepticism quickly faded upon reading the comments. As she put it, “I thought they were ugly at first, but after reading the comments, I guess they’re kind of fire.”

Moving from innocuous examples, consider the spread of misinformation on social media. Misinformation is false information that is spread unintentionally, while disinformation is false information that is intentionally disseminated to deceive or do serious harm.

Research shows that both misinformation and disinformation spread faster and farther than truth online. This means that before people can muster the resources to debunk the false information that has seeped into their social networks, they may have already lost the race. Complex contagion may have taken hold, in a malicious way, and begun spreading falsehood throughout the network at a rapid pace.

People spread false information for various reasons, such as to advance their personal agenda or narrative, which can lead to echo chambers that filter out accurate information contrary to one’s own views. Even when people do not intend to spread false information online, doing so tends to happen because of a lack of attention paid to accuracy or lower levels of digital media literacy.

Inoculation against social contagion

So how much can people do about this?

One way to combat harmful contagion is to draw on an idea first used in the 1960s called pre-bunking. The idea is to train people to practice skills to spot and resist misinformation and disinformation on a smaller scale before they’re exposed to the real thing.

The idea is akin to vaccines that build immunity through exposure to a weakened form of the disease-causing germ. The idea is for someone to be exposed to a limited amount of false information, say through the pre-bunking with Google quiz. They then learn to spot common manipulation tactics used in false information and learn how to resist their influence with evidence-based strategies to counter the falsehoods. This could also be done using a trained facilitator within classrooms, workplaces or other groups, including virtual communities.

Then, the idea is to gradually repeat the process with larger doses of false information and further counterarguments. By role-playing and practicing the counterarguments, this resistance skills training provides a sort of psychological innoculation against misinformation and disinformation, at least temporarily.

Importantly, this approach is intended for someone who has not yet been exposed to false information – hence, pre-bunking rather than debunking. If we want to engage with someone who firmly believes in their stance, particularly when it runs contrary to our own, behavioral scientists recommend leading with empathy and nonjudgmentally exchanging narratives.

Debunking is difficult work, however, and even strong debunking messages can result in the persistence of misinformation. You may not change the other person’s mind, but you may be able to engage in a civil discussion and avoid pushing them further away from your position.

Spreading facts, not fiction

When everyday people apply this with their friends and loved ones, they can train people to recognize the telltale signs of false information. This might be recognizing what’s known as a false dichotomy – for instance, “either you support this bill or you HATE our country.”

Another signal of false information is the common tactic of scapegoating: “Oil industry faces collapse due to rise in electric car ownership.” And another is the slippery slope of logical fallacy. An example is “legalization of marijuana will lead to everyone using heroin.”

All of these are examples of common tactics that spread misinformation and come from a Practical Guide to Pre-Bunking Misinformation, created by a collaborative team from the University of Cambridge, BBC Media Action and Jigsaw, an interdisciplinary think tank within Google.

This approach is not only effective in combating misinformation and disinformation, but also in delaying or preventing the onset of harmful behaviors. My own research suggests that pre-bunking can be used effectively to delay the initiation of tobacco use among adolescents. But it only works with regular “booster shots” of training, or the effect fades away in a matter of months or less.

Many researchers like me who study these social contagion dynamics don’t yet know the best way to keep these “booster shots” going in people’s lives. But there are recent studies showing that it can be done. A promising line of research also suggests that a group-based approach can be effective in maintaining the pre-bunking effects to achieve psychological herd immunity. Personally, I would bet my money on group-based approaches where you, your friends or your family can mutually reinforce each other’s capacity to resist harmful social norms entering your network.

Simply put, if multiple members of your social network have strong resistance skills, then your group has a better chance of resisting the incursion of harmful norms and behaviors into your network than if it’s just you resisting alone. Other people matter.

In the end, whether we’re empowering people to resist the insidious creep of online falsehoods or equipping adolescents to stand firm against peer pressure to smoke or use other substances, the research is clear: Resistance skills training can provide an essential weapon for safeguarding ourselves and young people from harmful behaviors.

Encouraging Sustainable Travel Habits

“Earth Day is a reminder that small changes, like choosing public transit over driving one day a week, can have a meaningful impact on our environment,” said Doug Chaffee, chair of the Metrolink Board.

With gas prices continuing to strain household budgets, the agency hopes the initiative will inspire more residents to consider rail as part of their regular commute.

Regional Connections Expand Access

Metrolink’s Earth Day promotion aligns with similar efforts by other Southern California transit providers. Riders can seamlessly connect to services operated by: LA Metro and the Orange County Transportation AuthorityRiverside County Transportation CommissionSan Bernardino County Transportation Authority and Ventura County Transportation Commission.

These partnerships extend the reach of fare-free travel across a six-county region, making it easier for riders to explore destinations without relying on personal vehicles.

Service Adjustments and Rider Tips

Passengers should note that trains will operate on a reduced weekday schedule, implemented earlier this spring. Despite the adjustment, all Metrolink lines and station cities remain in service.

For those planning a trip:

  • No ticket is required — simply board the train
  • Bikes are welcome, with capacity ranging from three bikes per standard car to nine in designated bike cars
  • A curated destination guide highlights attractions within walking or biking distance of stations

Environmental and Economic Impact

Metrolink is also promoting its Personal Impact Calculator, a digital tool that allows riders to estimate how switching from driving to rail can reduce greenhouse gas emissions and lower fuel expenses.

A Broader Trend in Public Transit

Fare-free transit days have gained traction nationwide as agencies look to boost ridership and promote sustainability. Southern California’s expansive commuter rail network makes it particularly well-suited for such initiatives, offering a viable alternative to one of the country’s most car-dependent regions.


Bottom Line

Metrolink’s Earth Day promotion is more than a one-day free ride — it’s a strategic effort to shift commuter behavior, reduce environmental impact, and showcase the convenience of regional rail. For Southern Californians, April 22 presents a low-risk opportunity to rethink how they travel.

Drones paired with AI could help search‑and‑rescue teams find missing persons faster

AI-powered drones equipped with thermal and infrared imaging are transforming search-and-rescue operations, enabling teams to locate missing persons faster and assess their condition—including signs of injury, consciousness, or life-threatening temperature changes—in real time.

A combination of infrared imaging, thermal imaging and color cameras on an uncrewed drone, along with an AI system to interpret the data, can help emergency responders and search-and-rescue teams locate, identify and track people who have gone missing in the wilderness. The experimental system helps responders pinpoint where a missing person is and determine whether they are hurt or even alive.

People who get lost or hurt while exploring nature can become stranded for days. Rescue teams often use drones to look for the person or signs of their whereabouts. The small drone my colleagues and I built at my lab at Kennesaw State University flies autonomously using a grid search pattern. It sends live video and images to a ground station operated by the rescue team.

When the AI system finds a person, it analyzes images to determine whether the individual is upright or lying on the ground. It segments parts of the person’s body, identifying the person’s head and the body’s position. It then zeroes in on the forehead. It extracts forehead temperature readings, pixel by pixel, from the imaging data to estimate forehead temperature. We have two papers detailing these findings accepted for the American Institute of Aeronautics and Astronautics Aviation Forum 2026 conference.

Our AI model then assesses whether the person is conscious or unconscious and identifies abnormal temperatures that could indicate heat stress, hypothermia or other physical complications, or death – all vital information for a search-and-rescue team.

In field trials we have conducted, the system has provided consistent temperature readings of the heads of volunteers from our research team who have walked out into a variety of environments, under different conditions.

Why it matters

It is critical to get accurate and timely information on the whereabouts of a missing person. The likelihood that the person will survive decreases steeply as time passes.

An AI-enhanced drone can make search-and-rescue operations significantly more efficient than sending teams of people out into the environment to search on foot, especially in poor weather conditions or under thick foliage. Rescuers who know whether a person is conscious or unconscious can also better gear up for what they need to do to retrieve the person and administer aid. Our technology could save lives.

What other research is being done

Search-and-rescue personnel use various kinds of drones, but the machines often lack the ability to positively identify humans, especially under thick foliage, in bad weather or when the person is lying down or unconscious. The AI-based technology we have developed overcomes those challenges.

Better sensors that are very lightweight, that can function at night or in rain, and can see more clearly through thick foliage could further improve our drone and drones used by others. Researchers are devising AI-powered sound recognition for detecting screams for help, advanced thermal imaging for better nighttime vision and autonomous drones that could act as first responders.

Also under development are drones that can carry heavy payloads, such as flotation devices, fly for up to 14 hours or perform real-time mapping of the ground below.

What’s next

One of our next steps is to have multiple drones fly together and autonomously coordinate search-and-rescue operations among themselves. This will allow the technology to cover a much larger area, perhaps hundreds of square miles.

We are also designing a large drone that can carry up to 110 pounds (50 kilograms) of payload and stay aloft for an hour.

The Research Brief is a short take on interesting academic work.
